FERTILIZER TEST
 CHART PREPA AIRED
TEN TEAMS TO INSPECT
County Agent to Give Farmers De. tailed Record-Big Business Men
 Show Interest.

| A printed chart, to be when com
 pleted complete record sf the tests
 of fertilizer being made on the A. C.
 Armstrong farm at Martinville, is be-
 ing prepared by County Agent T. NJ.
 Williams for use when the r patches
 are inspected on Friday, September 3. AS now planned by MT. Williams, ten team captains will be appointed and each will select nine men. These teams will check up the patches ac- cording to instructions given them by Mr Williams and Alfred Sachs, fer
 tilizer expert of the University of Arkansas. When the days inspection is finished, the cards will be complete except for the actual yield, which the holders can later copy from the coun- | ty newspapers, rounding out an ac- curate record of all the patches.
 In planning the tests, two objects have been kept in mind. The first was to make the tests accurate, and then to have them in form for easy Inspection by the public. Each plat consists of five rows, one end planted to corn and the other one to cotton with the same amount and formula of fertilizer used all through. Stakes placed in the dead" space in the center of each row show the amount and formula of fertilizer used. This "dead' space in the center is plant | ed, but not counted, being left out to avoid overlapping by either cotton or corn. Dead spaces at the end of each row were also left so that the strength of the fertilizer would not be wasted on weed growth, but would all go into the plants being cul- tivated. All estimates of yield will be on the basis of one acre.
 The planting of cotton or corn in the same row will furnish easy com parison, MT. Williams said, while the stakes In the center will readily show the amount and formula used.
 On the chart being prepared, the components of the fertilizer used on first column will list the chemical each patch, this being largely for l the technical men who will be at Mar tlnville. The second column will ex- press the formula in every day terms, such as acid phosphate, nitrate of soda, potash, etc, while the third column will show the amount used per acre. In the fourth column will be shown in figures the amount of actual plant food derived from the fertilizer. For example, 100 pounds of a certain formula of fertilizer may analyze 8.2.2, meaning eight pounds of phosphorus, two of nitrogen and two of potash or 12 pounds of plant food to the 100. In the fifth column will be printed the cost of the fertilizer treatment given each patch.
 The sixth, seventh and eighth col umns will be filled in by the teams. First, the teams will make a count ot bolls in the cotton patches. Then they will estimate the yield, separate columns being provided for cotton and corn. The last column will be left blank, to be filled in when crops have been harvested and the actual yield given publication. With the excep- tlon of the brief instructions given them by Mir. Williams and MT. Sachs, the teams will be allowed to devise their own methods of checking over results.
 Further interest is being created among the business men outside of this county. Two business men from Little Rock who will come to Martinville for the inspection are J. B. Young, president of the Southern Cotton Oil Company, and J. N. Adler, president of the Arkansas Fertilizer Company, both of Little Rock According to their letters to MT. Williams, their mission will be to gather information and to study the results of the tests for use in their business. Conway and Morrilton business men will be there Tn numbers, including merchants in- terested in improving farm production by the use of fertilizer and dealers in fertilizer.
 1 Outside of tests made at the college of agriculture, University of Arkan- sas, the tests undertaken by Mir. Will hams are perhaps the most extensive started in Arkansas. Much care and attention was given to the selection and preparation of the land used, and all the patches have been kept under close observation. Mir. Sachs has al-
 ready made one trip from the uni versity to aid in preparing the tests,
 and his further counsel will be avail
 able when he is at Martinville for the inspection.
