1, prepare materials: to prepare rotting agent, clean membrane cloth, shovels and other tools. 2, pile up the rotting: canola cake piled on the surface, each layer 20-30 cm high, stacked in 3-4 layers. 3, nutritional value: contains high protein, can provide nutrients for the crop. 4, the use of methods: take out the appropriate size of the block, mixed with sand and soil to the plant to be applied.
How to ferment rapeseed cake into organic fertilizer
