In these 12 towns 59 per cent, of all farm acreage, 59 per cent, of all 

 tillage land, and 78 per cent, of the cows were represented in the farms 

 which were signed up in 1937. 



Practically all of the progressive conservation farming practices were 

 carried out on farms in the program. This is indicated in the total 

 practices carried out on the 1,900 farms as compared with those on the 

 667 which signed up for the program. 



The following practices were reported on the 1,900 farms:

Acres of new seeding 2,528 2,229 88.13

There has been a definite increase in progressive practices as indicated 

 by a comparison of 1937 and 1935. For instance, in 1937 the acres of 

 new seedings were 2,528 as compared with 1,841 in 1935. This is an in- 

 crease of 681 acres, or 37 per cent. However, the acres of new seeding 

 are still very low and represent only two per cent, of the total tillage 

 land on the farms in the program.

Milk Solids-Not-Fat Upset Standards 



Milk standards based on total solids content are in danger of being 

 unfair because of normal fluctuations in the solids-not-fat. Studying 

 composite samples run on the University dairy herd for the last three 

 years, H. C. Moore finds that there is almost an inverse relationship be- 

 tween the production per cow per day and the average per cent, fat in 

 the milk — a normal relationship to be expected — but that there is no 

 correlation between the per cent, solids-not-fat and the production per 

 cow per day. 



Pastures at the University have been especially good each spring and 

 fall for the last two years, and this condition is reflected in the fact that
