In the spring ploughing, the author found that many farmers used livestock manure, leaf weeds, grass ash and other fertilizers. Farmers who are making fertilizers said: "After a week, the 'soil fertilizer' can be used to not only burn the roots of crops but also enhance the fertility of the soil to make the crops grow better."
It is understood that the use of in-situ houses, idle houses, and fields to process agricultural products and waste materials for local use will not only reduce manpower transportation but also reduce waste to save fertilizer costs. Here's a look at homemade fertilizer technology:
Ammonia water: Take 50 kg of fresh cow dung, 50 g of soy flour, 5 kg of cooked gypsum powder and mix for 3 days. Place it in a cool place below 25 ° C for 3 days. Apply 3 times more water than ammonia.
Ammonium sulfate: Take 50 kg of human urine, 5 kg of plaster, 25 kg of water, mix and mix for 10 days, and then apply fertilizer equivalent to ammonium sulfate.
