Farmhouse manure contains not only all kinds of macro and trace elements, but also some substances that can stimulate root growth and various beneficial soil microorganisms, which can improve soil structure because it is rich in humic acids and can promote the formation of soil aggregates. The soil becomes soft, improves soil moisture and air conditions, facilitates root growth, increases soil fertility and water retention, increases ground temperature, and promotes beneficial microbial activity and reproduction in the soil.
So, how to make farmyard fertilizer? The most common accumulation of farmyard manure is high-temperature composting, which is mainly based on raw materials containing more fiber. The appropriate amount of horse dung and human urine are added, and the fermentation temperature is higher. There are two ways: First, the ground method of high-temperature composting. Firstly spread 15-20 centimeters of stove-thick straw (5 centimeters or so) on the ground, then spread corn or stalks into a well-shaped ventilation ditch. Composting materials, piled up after the mud, unplug the erected ventilation stalk, into a vent hole. Second, pit high-temperature composting. The pit is a circular (also square) stalk column placed in the ditch to facilitate ventilation, but the bottom of the stalk is only a vertical and horizontal layer, about 3 cm thick. Spread the chopped compost material again, about 60 centimeters thick. After that, splash the dilute horse manure, human urine manure mixture and 4% lime and water layer. If you repeat the accumulation until the raw material is finished.
In the application of farmyard fertilizers also pay attention to several points: First, horses, cattle, pigs, chicken manure must be cooked after application. The second reason is that due to the slow release of nutrients from farmyard fertilizers and long fertilizers, and the time required for nutrient release and crops is often inconsistent, it must be used in conjunction with chemical fertilizers in order to fully realize its benefits. Third, some organic fertilizers have odors, pathogens, parasitic eggs, and some contain excessive heavy metals and harmful substances. They must be harmlessly treated before they can be used. The second year of animal manure composting is appropriate ( Fully fermented and cooked.
