Kitchen waste includes food wastes such as leftovers, bones, roots, leaves and peels. After in-situ treatment of compost by biotechnology, 0.6-0.7 tons of organic fertilizer can be produced per ton.
Leaves can be used as fertilizer, and the fallen leaves can be collected and concentrated in the roots of trees. After natural degradation, the content of organic matter in soil can be increased, the ventilation condition of soil can be improved, the water and fertilizer retention capacity of soil can be improved, and the acidity and alkalinity of soil can be adjusted, so that trees can grow more luxuriantly in the coming year.
