Theme 04: Soil Fertility and Plant Nutrition
Description
Studies were carried out to investigate the change of soil characteristics and pasture minerals as affected by fermented saw-dust pig manure(FSM) applied to mixed pasture of a brown volcanic ash soil during the period from October 1996 to October 1998. Pasture mixed with orchardgrass (Dactylis glomerata L.) and white clover (Trifolium repens L.) was treated with N 200kg/ha + P 300kg/ha +K 200kg/ha(T1), N 100kg/ha + 10 ton/ha FSM(T2), FSM 10 ton/ha(T3), 20ton/ha FSM(T4), 40ton/ha FSM(T5) or 80ton/ha FSM(T6). K and P contents of mixed pasture in the 3rd year after sowing increased significantly with increasing levels of FSM (P< 0.01). P and Ca contents of pasture applied with FSM was higher than those of pasture applied with chemical fertilizer (P< 0.05), while K was opposite. Soil pH, available phosphorus, exchangeable Ca and exchangeable Mg contents increased significantly with FSM application (P< 0.05).
