Green manure application to young coffee plants after establishment. II: Effects on soil properties
An experiment was carried out at Coffee Research Station Ruiru, Kenya, between May 1991 and December 1993 to study the effect of applying green manure derived from Leucaena leucocephala, Sesbania sesban, Calliandra calothyrsus, Medicago sativa, Desmodium intortum and Cajanus cajan to coffee plants on soil physicochemical properties. The application of the green manures resulted in an increase of 19 and 42 percent in soil organic carbon and exchangeable acidity, respectively. The soil N, K, Ca, Mg and P declined by 35, 37, 8, 37 and 8 percent respectively. It was concluded that green manures could not be used continuously in coffee. In addition, soil analysis ought to be carried out regularly so as to monitor and remedy adverse physiochemical changes that may affect coffee plant growth.
