The two yearlings were pastured from May 10 until September 30 at 

 a cost of 40 cents each per Aveek. Steer Xo. 1 gained l'2o pounds and 

 Ko. 2, 83 pounds in live weight, at which rate the cost per pound of 

 gain would be 6.58 cents for Xo. 1 and 0,01 cents for Xo. 2.

Soil tests witu fektilizkks, W. V. BiKxtKs, 15. S. — A report of 13 

 cooperative experiments with corn made in 18tK) in ten different counties 

 of the State. As in theex])erim('nts of 1SS".>. n'i>ort*'din r>ulletin No. 

 of the station (see Kxperinu-nt Station l\ec(»rd, vol. ii. p. 233), the ])lan 

 followed was that adopted by the conference of experiment station rep- 

 resentatives at AVashington in March. ISOl. and published in Circular 

 Xo. 7 of this t)llice. 



Fifteen twentieth-acre plats were u.sed in each of the experiments 

 except one. These plats were separated l)y intervening strips, making 

 the total area 1 acre. Tlie soils represented were mostly loams, 

 ranging from light .sandy to clayey loam. As indicated by the yields 

 of the unfertilized plats, they were in g(iicv:il (juite even in fertility, 

 being in this respect better adai>te(l for experimenting than nmny of 

 those used in 1SS!>, Nitrate of soda at tin- rate of 1<»0 i»ounds ]»er acre, 

 dis.solvcd boneblack at the rate of 320 pounds, and muriate (»f potash 

 at the rate of 100 pcmnds were used singly, two l>y two. and all thr«*e 

 together on seven plats; land i>lasler 10(> jtonnds. lime 100 ]»ounds, and 

 bainyard nuinure ."i cords p«'r acre were each usi'd on one ]>lat. and •"» 

 plats recei\(d no ai»i»lication. The analy.ses of these materials are 

 gi^ en. The fertilizing nnitcrials were in all ca.ses api)lied broadcast 

 u]»on the plo\v«'d huid an<l harrowed in just befon' planting. The corn 

 was planted in rows 3.J feet apart, and, with one or two exceptions, in 

 hills. The selection of the variety was left to the individual experi 

 menter, but in most ca.ses a yellow Hint variety was u.sed. The fertili- 

 zers, except the barnyard manure, were sui>])lied by the station. I']ach 

 experinu'nter was also furnished with maximum and mininuim registei' 

 ing thermometers nnd a rain gauge. In nearly every case the w<uk 

 Avas carried out according to the directions given. 



Each experiment was inspected twice during the season lt\ repre- 

 sentatives iVom the stati(»n. and the harvesting and weighing of the 

 croi>swere done in the ]>resence of an assistant. 



Kach of the thirteen exi>eriments, including two made at the station, 

 is reported by itself, and details are given in each case with reference 

 to the fertiliz(»rs a])i)lied ; the yield of corn and stover per acre ; the gain 

 or loss compared with the nnfertilized plats; the result of nu>asurements 

 made during the growing seas<»ii; the calculated results of the addition 

 of nitrogen, phosphoric acid, potash, complete fertilizer, Itarnyard 

 miinnre, land jHaster, and lime; the linaucial results; summary ot the
