The dynamics of phosphate in cattle manure compost were surveyed in a yellow soil cabbage field that used cattle manure compost for a period of 5 years (2010-2015). During this period, cabbage was alternately cultivated from September to February and from January to June. The cattle manure compost used in the present study contained phosphate that dissolves slowly, cabbage absorbed this phosphate efficiently. Soil in which cabbage was cultivated with phosphate from fertilizer contained more Al-P (phosphate that binds to aluminum) than the soil in which cabbage was cultivated with phosphate from cattle manure compost. When cabbage was cultivated with phosphate from fertilizer in soil to which cattle manure compost was applied, the soil contained considerable surplus phosphate that cabbage could not absorb. In addition, surplus phosphate could bind to aluminum. Hence, phosphate application should be reduced when cattle manure compost is applied during cabbage cultivation.
