SEEDING TO GRASS. 

 In this State spring seeding, with a shade crop of grain, 

 (usually oats) is the common practice. Summer seeding is 

 practiced to some extent, but does not fit in to the usual rotation 

 as well as spring seeding. It is doubtful if it is profitable to 

 grow oats or wheat in this State except as a nurse crop for 

 grass. They are exhaustive of plant food, particularly nitrogen, 

 and in proportion to the value of the crop are costly to grow. 

 In spring seeding with grain it is, of course, necessary to take 

 the demands of the grain as well as the grasses into account in 

 selecting a fertilizer. Where seeding follows corn in the rota- 

 tion, it usually happens that all of the farm manure is used on 

 the corn crop, and all the plant food for the grasses must be 

 otherwise provided. Where potatoes precede seeding, however, 

 usually farm manure can be used in seeding down. The old, 

 and still by far more common way, is to seed with rather slowly 

 available fertilizers, and crop the field until the grass yield is too 

 small to be profitable. A better way is to fertilize the land 

 annually and in case it is desiredto keep the field in grass more 

 than one or two years to top dress with soluble commercial ferti- 

 lizers. Based upon these various methods of treatment and 

 taking into account the amounts of fertilizing materials removed 

 by each crop (see page 137), the following formulas are sug- 

 gested. It should be remembered that thorough preparation of 

 the soil is as essential with grass as any crop.
