SCOPE OF ACTIVITIES

The Bureau of Plant Industry, Soils, and Agricultural

Engineering does research on crops, soil, machinery, storage,

transportation, and housing problems of general and sjjecialized farming and gardening. Most of the work is in cooperation with the State agricultural experiment stations.

At the close of the fiscal year 1952 the Bureau had research in

progress on 925 projects at 199 locations in 45 States, the

District of Columbia, Puerto Rico, Canal Zone, and 11 Latin

American countries.

Studies in the plant sciences are concerned with reducing

the hazards of production, improving the yield and quality

of crop plants, and lowering costs of producing and marketing crops. They include :

1. Introduction and testing of promising seeds and plants

from foreign countries as potential domestic crops and for

the genetic improvement of crops now grown. Ladino clover

and Korean lespedeza are good examples of introduced crops.
2 PLANT INDUSTRY, SOILS, AND ENGINEERING

Today's winter-hardy grains, disease-resistant vegetables,

and high-yielding forage crops reflect improvements resulting from introduced plants.

2. Breeding plants that will produce crops of high yields

and good quality and with resistance to diseases, insects, heat,

cold, drought. The research covers field crops, horticultural

crops, problems of transportation and storage, and disease

investigations of forest and shade trees.

3. Studies of the causes of plant diseases and methods for

their control. Crop plant diseases are under continual survey. The Bureau conducts a warning service to alert growers when severe outbreaks of certain major diseases threaten.

4. Fundamental studies of the nature of plants and key

factors in their environment. The findings help build up a

reservoir of knowledge out of which may come many practical applications. The discovery that plant-growth regulators such as 2,4-D could be used to kill weeds is an example.

Research on soils cmd their management is focused on the

relation between the soils and the crops grown on them. It

covers:

1. The basic physical and chemical properties of soils and

studies of microscopic plants and animals and their effect on

crops.

2. Methods of cultivation, irrigation, and crop rotation

and problems associated with saline and alkaline soils.

3. Investigations on the development of new fertilizers and

other soil amendments, their application to the soil, and new

techniques for measuring them precisely with radioactive

isotopes.

4. Classification and mapping of the soils of the United

States in detail—usually on a county basis—to indicate potentials for production. Studies are in progress in connection with the development of the basins of the Missouri,

Colorado, and Columbia Eivers.

Investigations in agricultural engineering are concerned

with the efficient use of power, labor, machines, and materials

in farming. They include:

1. Improvement of farm machinery and equipment for

seedbed preparation, planting, fertilizer placement, cultivation, and harvesting of crops, and for protecting the crops

from insects and other plant pests.
PLANT INDUSTRY STATION 3

2. Methods of drying hay and grains, ginning cotton, and

processing other crops and farm products on the farm or in

rural communities.

3. Studies dealing with income-producing applications of

electrical energy in farming, both as power and as radiations

that may affect the growth and production of plants or the

health and comfort of farm animals.

4. Improvement of designs of farm storage and service

buildings for strength and economy in materials and construction, of animal housing with special attention to environmental factors related to the health and production of

animals, and of farm housing for more livable homes.

National Arboretum.—The Bureau has charge of the development and maintenance of the National Arboretum, established by Congress in 1927. A National Advisory Committee,

appointed by the Secretary of Agriculture, assists in the

development plans.

PLANT INDUSTRY STATION

Headquarters of the Bureau are at Plant Industry Station,

a part of the 14,000-acre Agricultural Eesearch Center near

Beltsville, Md. The Station is on U. S. No. 1,14 miles north

of the Administration Building of the Department of Agriculture in Washington, D. C. It can be reached by Greyhound and Trailway busses traveling between Washington

and Baltimore.

Here are located the offices of the Chief of the Bureau, the

business staff, heads of all research divisions except those in

agricultural engineering, which are located in the North

Laboratory of the Center 3 miles away, and nearly half of

the Bureau's 2,100 employees. Five three-story red brick

buildings house offices and laboratories, the library, and an

auditorium. The four ranges of greenhouses, with connecting brick buildings for offices and laboratories of scientists

engaged in greenhouse work, cover more than 4 acres of glass.

One large greenhouse is used exclusively for research with

radioisotopes. A cafeteria at the Station is operated by the

USDA Employees Welfare Association.

More than 900 Bureau employees are scientists. The remainder are in the subprofessional, clerical, fiscal, crafts,

protective, and custodial jobs required to keep research mov-

ing smoothly. More than 1,000 members of the Bureau staff

are employed at field stations or are engaged in cooperative

research at the State agricultural experiment stations. In

addition the staff includes 705 collaborators, many of whom

are outstanding scientists on the staffs of the State experiment stations.

Bureau employees in the Washington area include a small

group of workers at the National Arboretum, which covers

about 400 acres in the District of Columbia, and at the Plant

Introduction Garden at Glenn Dale, Md.

BACKGROUND

Some of the work of the Bureau goes back more than a

century. In 1819 the Treasury Department directed United

States consuls to collect seed, plants, and information on climate, soil, propagation, cultivation, and insect pests in the

countries where they were assigned. Twenty years later

the Commissioner of Patents was authorized to collect foreign seeds and plants for distribution to farmers in the

United States. In 1856 the Commissioner employed a botanist in the Agricultural Division and set up a garden on the

Mall in Washington for the propagation of sorghum. The

distribution of cotton and tobacco seed was begun in 1862,

the year the Department of Agriculture was established.

Several lines of research were brought together in 1901 to

form the Bureau of Plant Industry. These included the

study of fruit and vegetable diseases and physiology, research to improve cereals, fibers, tropical crops, grasses and

other forage plants, investigations in the production of tea

in the United States, and the introduction of foreign seeds

and plants. Many of the studies were carried on in the experimental gardens and grounds of the Mall around the Department in Washington. Some work had been initiated at

the Arlington Experimental Farm across the Potomac. Cooperative research with the States has been an important part

of the Bureau since its beginning. That first year joint research in grass and forage crops was carried on in 13 States.

Studies in both soils and agricultural engineering were

at one time in separate Bureaus. The Bureau of Soils was

established in 1901, that of Agricultural Engineering in 1931.
ORGANIZATION 5

The work in soils was transferred to the Bureau of Plant

Industry in the 1930's. When the research in agricultural

engineering was combined with that of plants and soils in

19Î3, the Bureau was given its present name.

The Bureau has been directed by seven Chiefs : Beverly T.

Galloway, 1901-13 ; William A. Taylor, 1913-33 ; Knowles A.

Ryerson, January-October 1934; Frederick D. Eichey,

1934-38; E. C. Auchter, 1938-42; Robert M. Salter, 1942-51;

and Albert H. Moseman, November 1951 to present time.

ORGANIZATION

The Office of the Chief of Bureau exercises general supervision over the work of the divisions; formulates general

policies; makes decisions as to changes in the trend of research ; coordinates the activities of the Bureau in conformity with Federal statutes and governmental regulations;

promotes cooperation between divisions to obtain maximum

efficiency commensurate with freedom of action necessary to

successful research; and develops and makes effective general policies affecting relations with other bureaus of this

and other Departments and with State agricultural agencies.

The administrative divisions are responsible for the business contacts and operations of the Bureau, including : The

preparation of the budget and estimates, the allotment of

funds, and the approval, audit, and maintenance of expenditure records; the appointment of employees and the maintenance of records of all personnel transactions ; the purchase

of property, supplies, and equipment, and the maintenance

of property records; the handling of claims for injury to

Federal employees and damage to private or Government

property ; the preparation of leases ; the supervision of cooperative arrangements; and the supervision of the business

practices of the Bureau's field stations.

The management of buildings and grounds at the Plant

Industry Station is under the direction of two superintendents—one in charge of buildings and utilities, the other

in charge of the experimental farm.

Biometrical Services acts primarily as a biometrical consulting service unit to the research staff of the Bureau. The

work relates mainly to problems of design of experiments

and of sampling schemes and to methods of analysis of ex-
6 PLANT INDUSTRY, SOILS, AND ENGINEERING

perimental data. Also, some research on applied statistical

methodology pertinent to Bureau research problems is carried out. The services of this unit are available to all research personnel of the Bureau.

The Division of Information is responsible for the editing

of the scientific, technical, and popular manuscripts of the

Bureau and the reviewing and compiling of other research

material for publication; for the preparation of material

for radio broadcasts and statements for the press on scientific

developments of current interest ; for special report writing;

for the maintenance of photographic and other illustrative

material for use within the Bureau ; and for aid to free-lance

and other writers interested in the Bureau's accomplishments.

The Beltsville Branch Library, located on the third floor

of the Administration Building, is a branch of the Library of

the United States Department of Agriculture. Through cooperation with that and other libraries and with the

Entomology Sub-Branch Library at the Agricultural Eesearch Center, it provides the facilities needed by research

workers.

field stations to cooperating agencies and individuals in suitable localities, and provides technical assistance on all phases

of hevea rubber production. Investigations include study

and control of important diseases, factors affecting growth

and yield, and, through jungle selections and a comprehensive breeding program, the development of superior strains

combining resistance, high yield, and other desirable qualities. It makes field and laboratory studies of guayule and

other native and introduced plants that can be grown in the

United States as possible domestic sources of rubber. Investigations include selection, breeding, and disease studies

to develop strains with improved growth and yield characteristics. It furnishes information on wild or cultivated

rubber-bearing plants to other governmental agencies, private companies, and individuals interested in sources of rubber for normal or emergency needs.

Sugar Plant Investigations

C. H. WADLEIGH, head of division. Room 215, South Building, Plant

Industry Station.

The Division of Sugar Plant Investigations, in cooperation with State agricultural experiment stations and with
ORGANIZATION 11

organizations representing farmers and factories comprising

the sugar beet and sugarcane industries, conducts research

on production of sugar beets and sugarcane, the important

domestic sources of sugar, and on sugar sorghum, now grown

for sirup but recognized as a potential new source of sugar.

The research objectives are to discover more efficient methods

of crop production by means of breeding, agronomy, plant

physiolojgy, and plant pathology investigations.

Breeding is conducted to develop varieties of sugar beets,

sugarcane, and sugar sorghums improved in disease resistance and with yield and quality maintained or increased.

Foundation stocks of seed and plant cane of the varieties

produced in the breeding programs for the three sugar plants

are supplied to cooperating agencies to make large-scale increases of the new and improved sorts whereby they may

be promptly furnished to growers. In the phases of work

that deal with multiplication of the improved planting

stocks, cooperation with the industry is particularly valuable.

In agronomic research more efficient methods in growing the

sugar plants are investigated, including restudy of cropping

practices to make possible greater mechanization of opera.-

tions. In plant pathological investigations, measures arc

sought to protect the sugar crops from losses from plant diseases, including prevention of deterioration of sugar beets

and sugarcane while stored prior to processing. Recent research has stressed the development, by breeding, of sugar

beet and sugarcane varieties suited to a fully mechanized

program of crop production.

ORGANIZATION 13

tion of forest products. Throughout the lifetime of trees,

in the nursery, plantation, or forest, they are exposed to

many organisms that may reduce their growth rate, kill

them, or otherwise destroy their value for commercial,

esthetic, or other uses. Forest products are subject to decay

and degrade by fungi. The Division conducts surveys, including airplane surveys, to determine distribution and rates

of spread and intensification of forest-tree diseases. The

Division studies the causes of native and introduced diseases

and devises practical control measures for them. The Division maintains 19 field laboratories and in its activities cooperates with other Federal agencies. Itis directly responsible for forest-disease research for the Forest Service, the

Soil Conservation Service, and the National Park Service.

Cooperation is also maintained with State agricultural experiment stations and State and municipal forest and shadetree officials, with colleges and universities, and with private

timberland owners. The Division conducts investigations on

decay in buildings in cooperation with the Housing and

Home Finance Agency and investigations on decay in ships

and in wooden containers for the Federal defense agencies.

and other stone fruits; grape; and small fruits such as

strawberry, blackberry, raspberry, blueberry, and cranberry ;

citrus and subtropical fruits such as date, avocado, mango,

and fig; edible nuts such as pecan, almond, walnut, filbert,

and chestnut; and the oil-bearing tung. The research^ includes studies of the nutritional requirement of the various

crops and of cultural methods and practices and their relations to size, regularity, and quality of the crop ; studies of

varieties to determine their suitability for diverse uses and

conditions ; studies of rootstocks for resistance to fungi,

nematodes, and other disease-producing agents, salt tolerancej and compatability ; breeding and selection to obtain

varieties of greater merit for different purposes and to extend
14 PLANT INDUSTRY, SOILS, AND ENGINEERING

ranges of adaptation, partly through detection and induction

of polyploidy (basic studies that make possible some valuable crosses) ; and studies of fungus, bacterial, and virus

diseases, physiological disorders, and nutritional deficiencies

and their prevention or control. In these lines of research

extensive cooperation is maintained with other Federal

agencies and with State agricultural experiment stations and

less extensive cooperation is maintained with commercial

and grower groups.

quality evaluation for fresh, frozen, or canned use ; various

methods of packaging, including consumer packages ; packing-house practices such as washing and waxing; precooling

methods, including warehouse precooling, vacuum cooling,

hydrocooling, and car precooling; refrigeration and protection against freezing during transport in refrigerator

cars, trucks, airplanes, and ships ; development of best methods of storing horticultural crops and displays in retail

stores ; and means of controlling diseases that cause damage

to the crop during shipment, storage, and marketing. The

Division tests various types of equipment developed for

transporting fruits and vegetables and assists in drawing up

specifications for improving construction of refrigerator

cars, trucks, air cargo compartments, and refrigerated ships*

holds. Particular attention is given to rail refrigeration

services best suited to the commodity, considering cost and

temperature required. It investigates the physiological response of horticultural crops to temperature, relative humidities, and modified atmospheres that may be encountered in

storage or shipment. The diseases that cause most damage

to horticultural crops after harvest are identified and studied
ORGANIZATION 15

to determine what transit and storage temperatures are

needed to retard their growth. Tests are made with chemical washes, treated wrappers, and volatile fmnigants to

perfect means of reducing losses from post-harvest diseases.

The general aim of the work is to improve the quality of

fruits and vegetables offered for sale to the consumer and

to prevent needless loss hj the use of faulty practices or

equipment. This research is conducted in cooperation with

State agricultural colleges and experiment stations, other

Federal agencies, growers, shippers, marketing groups, and

transportation agencies.

florists.

Plant Exploration and Introduction

C. O. ERLANSON, head of division. Room 234, North Building, Plant

Industry Station.

The Division of Plant Exploration and Introduction serves

as a coordinating agency for obtaining from all parts of the

world new, rare, and promising plants. These may be useful

in the development of new crop industries directly, for the

diversification or expansion of economic needs, or as mate^

rial to be used by plant breeders, especially as related to the

development of disease-resistant and insect-resistant crops.

The Division provides initial protection against the introduction of foreign insects and diseases through inspection and

quarantine propagation in cooperation with the Bureau of

Entomology and Plant Quarantine. Through Federal and

cooperative introduction stations, propagation and preliminary testing of plant introductions are undertaken, followed
ORGANIZATION 17

by distribution to growers or by the maintenance of important germ-plasm for future breeding programs. The Division conducts studies of potential crop plants and of soils

and climates of foreign countries as compared with those of

this country, with a view to introducmg materials best

Vegetable Crops and Diseases

V. R. BoswELL, head of division. Room 302, North Wing, Administration Building, PlantIndustry Station.

The Division of Vegetable Crops and Diseases is concerned

with the development through research of new varieties, new

methods and practices, or both : To reduce the cost of vegetable production; to decrease the hazards from diseases; to

increase yields and nutritive value; and to improve the quality of the crops for various regions and seasons, for diverse

or specific home, farm, and industrial uses, and for different

methods of culture, handling, and processing. In addition

to vegetable crops, research on peanuts, mushrooms, and

vegetable seeds is also included. To obtain the objectives,

basic and applied research is done by plant breeders, phytopathologists, plant physiologists, horticulturists, and other

specialists of the Division in cooperation with other Federal

agencies, State agricultural experiment stations, and industrial and other commercial agencies including growers, seedsmen, shippers, food processors, and manufacturers.

SOIL GROUP

F. W. PARKER, Director of Soils Research. Room 237, Soils Building,

Plant Industry Station.

research on the preparation, technology, and use of fertiliz-
18 PLANT INDUSTRY, SOILS, AND ENGINEERING

ers, liming materials, and soil amendments ; develops standards and methods for analysis of these products; and

compiles statistics on the resources, supplies, production,

consumption, and trade.

Soil Management and Irrigation Agriculture

R. Q. PAEKS, head of division. Room 323, Soils Building, Plant Industry Station.

The Division of Soil Management and Irrigation Agriculture conducts research on soil management practices to

develop successful agricultural systems that are capable of

maintaining or raising the level of soil productivity under

dry-land agriculture, under humid conditions, under irrigation and drainage, and on saline soils ; conducts basic research

on factors governing soil productivity and plant growth and

quality, such as physical, chemical, and biological factors

affecting fertilizer requirements, salinity, organic matter,

and soil organisms, and studies the genesis, morphology, and

nomenclature of soils.

Soil Survey

C. E. KELLOGG, chief of division. Room 328, North Building, Plant

Industry Station.

The Division of Soil Survey carries on a Nation-wide program of classifying and mapping the soils of the United

States. In this program, known as the Soil Survey, the

soils of the entire country will eventually be mapped in such

detail that anyone who is interested in them—farmer, land

buyer, agronomist, horticulturist, appraiser, tax assessor, or

highway engineer—can locate the kinds found on each farm,

know their characteristics, and compare them directly with

the soils on any other farm. Such a survey tells the farmer

whether his soils are like those on other farms in his county.

State, or region or on the experimental plots or fields of his

State agricultural experiment station where new crops, tillage methods, fertilizer practices, or drainage or irrigation

practices are being tried or have proved successful. It

enables him, therefore, to tell with more certainty whether
FIELD ACTIVITIES 19

the introduction of a new crop, variety, or farm practice is

likely to succeed on his farm. All this work involves the

identification, definition, description, classification and correlation, and mapping of many kinds of soil types throughout the country. The published reports on each survey,

whether county-wide or of less extent, describe each soil as to

depth, drainage, stoniness, slope, thickness, friability, and

permeability of layer, its texture, and the important chemical characteristics that affect its fertility. In addition to

this program, which is directed under four regions, with

headquarters, respectively, in Maryland, Tennessee, Nebraska, and California, the Division cooperates with State

agricultural experiment stations, the Soil Conservation Service, the Forest Service, the Tennessee Valley Authority, and

other agencies by furnishing experienced correlators to assist

in classifying the soils in terms of the Nation-wide system, so

that the work of these agencies will help complete the soi?

survey coverage of the whole country.

National Arboretum

H. A. GUNNING, assistant director, acting in charge. Twenty-eighth

and M Streets NB., Washington, D. 0.
