FARM DRAINAGE
 VERY IMPORTANT
Can Be Secured From o. G. Bax- ter, Old State House.

l attention Of the land owners Of Ark ansas at this season of the year. En-
 gineering advice on these subjects
 can be secured for tho asking by sp- | plying to o. c. Baxter at the Old
 State House, Little Rock, Ark. Mr- | Baxter, who is the Senior Drainage Engineer for the U. S. Departm ent of
 Agriculture in this district, is co-ope- rating with the Extension Division of | the University Of Arkansas, through 1 the county agents, in an effort to be Of greater service to the people of l this state. In speaking of the need and value of proper farm drainage, MT. Baxter says:
 "In traveling over the agricultural
 districts of Arkansas and the sur rounding states, one is impressed by is due to a lack of proper drainage. This lack of drainage Is indicated by the growth of coarse grass and weeds, and by sicllly, thin, and stunted crops where attempts have been made at cultivation. It is customary to blow around the wet spots, thereby incur ring a loss on account of cultivation methods in addition to that due to the poor quality of the crop. The yield can be increased on many farms that are entirely under cultivation by the construction of good drainage sys- tems.
 The effect of later planting and 1oo .3, is also apparent in the harvest, espe- cially where the crop must be made before the droutl begins. Some of , the largest cotton planters in Missis
 sippi state that drainage is one of the main factors in the fight against the boil weevil, as thorough drainage allows the crop to be planted from 10 days to two weeks earlier in the spring and permits more timely c,ilti- vation. thereby resulting in an earlier
 maturing of the crop.
 Tile drains will not only dry and warm land that is wet and cold, but they have a marked effect upon tho physical structure of the soil. After drainage, the soil becomes looser; it therefore is moro easily cultivated and the surplus water readily passes through the larger pore spaces. No fear need be had of too much drain age as sufficient moisture for plant growth remains on the soil particles and cannot be removed by the drains.
 Drainage adds no plant food to the soil, except the nitrogen that certain plants gather from the air and that replaces the surplus water between the soil particles. But the warm air circulating through the soil induces the growth of bacteria that release certain food clements from insoluble compounds and make them available for the use of plants. In this way,
 drainage increases the fertility of soils
 In drained soil crops have deeper roots systems than do those on wet CT poorly drained soils. The roots of most crops will not go into saturated soil, aud will die if kept in water without air for more than short time. The root system does not ex- tend to the depth at which the soil is permanently wet, but only to depth that is somewhat above the stage where the water table remains long enough to injure the roots. In wet soils the water table is high during the planting season and early growth of the crop. The root system adapts itself to this depth and later, when the
 
 ter is lowered, the plants suffer from drouth and for want of food.
 The most practical drainage system is one that is adequate, permanent, uses the least possible land, and Is not hindrance to cultivation. Tile drains which empty into either open or closed outlets most nearly provide such a system. With the open-ditch system, much valuable land is occu- pied, the drainage is seldom thorough. and the ditches become filled and have to be frequently cleaned. Open ditches occupy considerable per cent of the area drained.
 Taking all factors into considera, tion tile drains are more economical in the end even though they are more expensive to install. There is no req son why the tile drainage system, properly constructed, should not re- main in proper condition and give sat isfaction indefinitely.
 In order that the best results may be obtained from a drainage system. it is essential that it be p: operly de- signed. One not eXperierced in this kind of work should not take the re- | sponsibility Of planning any consider able expenditure for drainage. Com plete surveys and examinations should be made in order to determine the most practical and economical plan. ] Constructor work should be careful. 1 ly done in order that the tile shall be
 laid in strict accordance with the grades established by the engineer who planned the work.
