MANURE AND STRAW. 



When manure is applied to a particular crop, other crops following 

 in the rotation get part of the benefit. This cost then should be 

 distributed among the different crops grown. When applied directly 

 to wheat, 50 per cent of the estimated value was charged; when 

 applied to the crop imjnediately preceding, 30 per cent was charged; 

 and when two other crops preceded, 20 per cent was charged to the 

 wheat. 



The largest number of farmers reporting the use of manure (80 

 per cent) was for Saline County, Nebr., while the smallest number 

 was for Keith County, Nebr. In Ford County, Kans., and Keith 

 County, Nebr., only 1 per cent of the total wheat acreage was 

 manured. Farmers in these counties regard manure and straw of 

 more value for top dressing to conserve moisture and prevent "blow- 

 ing" of the land than as a fertilizer. In these two counties not 

 enough moisture is available to make manure valuable as a fertilizer. 



For the spring-wheat districts 8 per cent of the total wheat acreage 

 received an application of manure and straw, while for the winter 

 wheat only 5 per cent of the total acreage was covered. (See Table 

 XXIV.) 



OREEN MANURE. 



In St. Charles County, Mo., it is a common practice to plow under 

 a certain number of acres of new clover seeding each year. Corn 

 is usually grown on this land for one or two years, followed by wheat 

 for one or two years more. It will be readily seen that this practice
