Abstract
|
|
|
|
To investigate the effects of applying animal feces to the mulberry field on the chemical properties and mulberry leaf yield, poultry, pig and cattle feces were applied to the mulberry field making-up the sand loam from 1988 to 1990. The chemical properties of the mulberry field have been improved by the application of the poultry, the pig, and the cattle feces, increasing pH level, organic matter, P2O5 and exchangeable cation, especially Mg and K. Applying the pig feces and poultry feces to the mulberry field increased leaf yield during autumn rearing season, but not increased during spring rearing season. Applying animal feces to the mulberry field increased the content of total-carbohydrate in the leaf in autumn.
