Experiments by l\ 'SL Mktcalf^ 4i/2 Miles North op 



Geneva. 



Kiraij or light sand^ upland with stiffcr red subsoil, eight 



inches from surface. 



For .yields see table on pages 64 and 74. 



Jn UJOl. This was lie fourth crop after clearing, all pre- 

 vious crops being corn with cowpeas and peanuts between. 

 Xo mention is made of rust. 



On this fresh laud where leguminous crops had grown for 

 ■several years, phosphate was the only material of marked 

 value. Phosphate alone increased the yield 29G pounds of 

 -seed cotton per acre, affording a net profit of $6.02 per acre, 

 •after paying cost of fertilizer and picking and ginning of 

 increase. 



Ill iDO^ The imni -'ii-i^ely preceding crop was oats, which 

 in turn had been preceded by two crops of corn, probably 

 Vith cowpeas or peanuts between, as is customary in that 

 'locality. 



The time since clearing is not stated. 



Protracted drought and abundance of cotton caterpillars 

 in October reduced the yields. No mention is made of black 

 rust, but ^rr. Metcalf writes that "Plots 1, 2, 3, 4 and 8 had 

 anucli of what we know as red rust." In this unfavorable 

 ..veav kainit was by far the most effective single fertilizer, 

 increasing the yield when used alone 369 pounds. The com- 

 plete fertilizer containing a full ration of kainit increased 

 the yield 488 pounds of seed cotton, affording a net profit of 

 ^6.31 per acre. 



Mr. Metcalf writes: "I learn from this experiment that 

 It pays to use lots of guano and of high quality." 



In 1903. This was the sixth vear since the clearing of 

 this land. The crops in 1902 were oats, followed by Span- 

 ish peanuts. There was no rust. This experiment is ren- 

 <dered inconclusive by the wide variation in the yields of
