REQUIREMENTS OF FIELD CROPS.

County, N. Dak., Spink County, S. Dak., and Pawnee and Ford 

 Counties, Kans. 



A light crop of straw in the spring-wheat region accounts in part 

 for the low twine requirements in these districts. The header was 

 used on 90 per cent of the wheat acreage in Morton County, N. Dak. 

 The header was also used extensively in several of the winter-wheat 

 districts. 



Eighty per cent of the farmers in Saline County, Nebr., reported 

 the use of manure. In Ford County, Kans., and Keith County, 

 Nebr., only 1 per cent of the wheat acreage was manured. Here 

 manure appears to have its greatest value as a top dressing, to 

 prevent blowing. Eight per cent of the total wheat acreage received 

 an application of manure and straw in the spring-wheat districts, 

 and in the winter-wheat belt only 5 per cent of the total area was cov- 

 ered. Manuring may therefore be considered a minor operation in 

 the production of wheat. 



Commercial fertilizer was not used in any of the areas visited except 

 Missouri, and in this State not to an appreciable extent except in 

 Jasper County.
