Peanut. 



The peanut is a leguminous plant, and, like others of 

 this family, is not specifically benefited by nitrogen, 

 but responds readily to liberal dressings of phosphoric 

 acid and potash. The fertilization suggested for green- 

 manure crops, namely, a mixture of three parts acid 

 phosphate and one part muriate of potash, or equal 

 parts of acid phosphate and kainit, may be used for 

 this crop with great advantage. The applications, if 

 frequently made, need not exceed 300 to 400 pounds 

 to the acre. Like other leguminous crops, it is specifically 

 benefited by lime, medium dressings of which (20 bushels 

 to the acre) should be made at least once in four years. 

 In the districts in which this crop is successfully grown, 

 lime marls are frequently obtainable at slight expense, 

 and may be used with great advantage. 



Roses and other flowering plants. 



In the growing of roses and other herbaceous plants, 

 of which the flowers constitute the crop, great care is 

 usually taken in the preparation of the soil, and natural 

 soils are seldom used. Notwithstanding the richness of 

 the prepared soils, the crops are benefited by the addition 

 of commercial fertilizers, particularly those phosphatic 

 in their nature. Ground bone is especially useful, since 

 it furnishes both nitrogen and phosphoric acid in slowly 

 available f onns, and usually sufficient nitrogen to meet the 

 needs of the plant, as excessive quantities of this element 

 cause a too vigorous and rank growth of foliage, which is 

 not accompanied by profuse flowering. A good mixture 

 for the prepared soils, therefore, may consist of four parts 

 of ground bone and one part of muriate of potash, which
