Hay and Grain Crops.

J. B, Lawes. 4 Compared with ift selling price, hay removes more of the soil constituents from the land than mostuf'onr other salable products. One bandied potinds or nay will remove nearly as much nitrogen and touch more mineral malter than 100 pounds of wheat. These considerations most all be studied when th«rquestion comes as to the profitable application of expensive manures. While, therefore, the evidence ia somewhat against the use of artificial manures when hay is grown for sale, it by wnfttyjrass tana &. ossa for the production of meat, milk; butter or cheese; and to Illustrate this ! will .merely allude to o^o e ingrediant/viz.: • more than ons pound. Of 100 flbsrweight oontaines little over half a podtuf'-of mineral matter, or about onethirteenth part of what would be contaiped in 100 lbs. of hay, while butter robs the land of nothing. If land has been Impoverished by the sale of hay,

and hay is to be sold, dung isTtlje Awjirt manure to apply; hut if lima so impoverished is intended for toe future to produce milk, meet or other enlmel products, potash is sure farbe wanting, and the best manure to apply quantity qf kanit salts, and} in addition to whichever of these substances is [■elected, 200 lbs. of superphosphate of lime andtrom sixty of nitrate of soda. If, however, the land 4ie» been Impoverished merely by feeding stoek then the exhaustion will b® nacre likely due to- the absence of nitrogen and phosphate, and fertility must be restored by an application of these substances as manures.
