RESULTS OF BASIC SLAG TESTS WITH CORN. 



In Tables XVI and XVII are embraced the results of these tests 

 conducted during 1906 at the Edgecombe and Iredell farms. The 

 application yielding most favorably at Edgecombe above cost of fer- 

 tilizer was one consisting of 65 pounds of dried blood, 55 pounds of 

 basic slag and 25 pounds of manure salt per acre, applied in the drill 

 just before planting. This gave a value above cost of fertilizer as 

 seen by Table XVI of one and sixty-six hundredths more than 

 the unfertilized plat. The application per acre ranking second, 

 third, fourth and fifth were: 65 pounds of dried blood, 110 pounds 

 judged by this year's results, were in the following order: 3214 

 pounds of dried blood, 30 pounds of nitrate of soda, 110 pounds 

 of basic slag and 25 pounds of manure salt; and 65 pounds of dried 

 blood, 220 pounds of basic slag and 25 pounds of manure salt respect- 

 ively. 



At the Iredell farm the most favorable applications per acre, as 

 judged by this year's results, were in the following order: 32 Vo 

 pounds of dried blood, 30 pounds of nitrate of soda, 110 pounds of 

 basic slag and 25 pounds of manure salt; 130 pounds dried blood, 

 220 pounds of basic slag and 50 pounds of manure. salt; 65 pounds 

 of dried blood, 220 pounds of basic slag and 25 pounds of manure
