The response of lespedeza to lime and fertilizer
1939
Stitt, R.E.
1. On a Cecil loam soil which had received a complete fertilizer during the previous season Korean lespedeza did not give a significant response to lime and fertilizer and Kobe lespedeza responded slightly to lime. 2. On a Cecil gravelly loam soil, which was too poor for normal growth without treatment, Kobe, Korean, common, and sericea lespedeza responded to phosphae and lime. The Korean variety responded more to lime than either Kobe or common. 3. In their ability to survive drought under conditions of low phosphate availability the varieties ranked with Kobe first, Korean second, and common third. Common seemed unable to survive drought with the level of fertilizer treatment provided. Lespedeza sericea with its perennial root was not affected by the drought. 4. The calcium and crude protein content of Kobe and Korean lespedeza plants growing on the Cecil gravelly loam were increased by the addition of both lime and superphosphate. The phosphorus content was increased by application of superphosphate.
