The absorption of mineral elements by forage plants. I. The phosphorus, cobalt, manganese, and copper content of some common grasses
1947
Beeson, K.C. | Gray, L. | Adams, M.B.
The phosphorus, cobalt, manganese, and copper contents of 15 grasses grown under uniform conditions in the greenhouse have been determined. Kentucky bluegrass absorbed the highest quantities of all elements except manganese. Timothy proved to be one of the least nutritious grasses as measured by these constituents. Dallis grass, orchard grass, Johnson grass, and red top are intermediate. There was no overall correlation of composition with yield. Grasses of comparable composition have been grouped for survey purposes.
