MEADOWS AND PASTURES 101 



If a high percentage of clover is desired m the hay the 

 nitrate of soda should be omitted, and the following 

 applied to the acre : 



Acid phosphate 100 pounds 



Basic slag meal 400 pounds 



High grade sulfate of potash 150 to 200 pounds 



For permanent meadows producing market hay com- 

 posed largely of grass, Brooks recommends with much 

 confidence the use to the acre of the following amounts of 

 fertilizer : 



Nitrate of soda 150 to 250 pounds 



Basic slag meal . 300 to 400 pounds 



High grade sulfate of potash 75 to 100 pounds 



Top-dressings of nitrate of soda alone are not considered 

 desirable for a longer period than two years. 



On peat marsh soils in Wisconsin the yield of hay from 

 a mixture of timothy and alsike yielded without treatment 

 2727 pounds hay an acre. An application of 275 pounds 

 acid phosphate an acre increased the yields on two plots 

 to 5015 and 5158 pounds respectively. Sulfate of potash, 

 100 pounds to the acre, increased the yields on two plots 

 to 4588 and 4781 pounds respectively. When both ferti- 

 lizers were used together in the amounts above indicated 

 the results were not as good as the phosphate alone. 



At the West Virginia Experiment Station the applica- 

 tion of both barnyard manure and commercial fertilizers 

 greatly increased the yields of timothy. On the larger 

 part of a 4-acre field that yielded 1 ton hay or less a year 

 the average application for 6 years of 17 loads of manure 

 brought up the yield to the acre from 3775 pounds the 

 first year to 11,315 pounds the sixth year, or an average
