The Bulletin 43 



In the table above is given not only data with reference to the com- 

 position of the different soils but a record is made of the plats of the 

 different fields from which the soil samples for analyses were drawn. 



KATE OF SEEDING OF ALL CKOPS. 



The rate of seeding on the different experimental fields was the same. 

 For the different crops the manner and rate of seeding were as follows: 



Corn was planted in 4-foot rows, and about 8 pounds of seed were 

 used per acre. 



Wheat was sown broadcast or drilled at the rate of 1^4 to 1^/2 bushels 

 per acre. 



Oats were sown broadcast or drilled at the rate of 2 bushels per acre. 



Cotton was planted in 3^^ to 4-foot rows, the seed being put in at the 

 rate of a bushel per acre. 



Red clover was seeded broadcast during the early spring on fall-sown 

 wheat, using about 12 to 15 pounds of seed per acre. 



Criinson clover was sown during the early fall and lightly covered by 

 means of a spike toothed harrow or single horse cultivator. 



Cowpeas were sown broadcast in late spring or early summer at the 

 rate of about 4 pecks per acre. 



Rye M'as sown during the early fall at the rate of 4 pecks per acre. 



Hairy vetch, sown with oats, went in at the rate of 30 pounds of vetch 

 seed with about 1% bushels of Red Rust Proof oats. 



TREATMENT AND RESULTS ON CHARLOTTE FIELD NO. I. 



The soil of this field is typical Cecil clay. This type of soil is found 

 more or less widely distributed throughout the Piedmont Region of the 

 State, and of other States through which the Piedmont Plateau extends. 

 The field is typical of the soil in Mecklenburg and Gaston counties. 

 In both the counties Ave find this soil type running comparatively high 

 in phosphoric acid. These experiments were started in the spring of 

 1910. The field was laid off into ten one-thirtieth acre plats, the plats 

 being 20 by 72.6 feet and a four-foot space between plats. Com was the 

 first crop of the following two year rotation grown on the field : 



First Year — Corn, with cowpeas. 



Second Year — Cotton, with crimson clover. 



The cowpeas in the rotation are sown broadcast in the com at the 

 last cultivation, and the crimson clover in the cotton after the first pick- 

 ing. As these crops were grown in the rotation purely for soil improve- 

 ment, they were in all cases turned back into the soil. The cowpeas 

 did not in any of the years get more than eight to ten inches high and 

 bore but few pods. The crimson clover sown during the falls of 1911 

 and 1913 in the cotton plats made practically very little showing. 



In the following table is given the fertilizer treatment, the yields 

 from the different plats and the gains resulting from each fertilizing 

 constituent used alone and in combination with the other two on this 

 field :
