What are the precautions for winter farm composting? It is a good time to build farmyard manure in winter, but due to the low temperature in winter, the fertilizer is not easy to ferment. The following links must be grasped when composting:
Site selection
When composting, choose a place that is closer to the fertilizer source, leeward to the sun, and convenient to transport.
2. Base pile
The shape of the manure pile is preferably rounded and has a height of more than 1 m to facilitate heat preservation. After determining the bottom surface of the compost, first lay a layer of culvert soil or chaotic grass, and then pile up the mixed farmyard manure layer by layer. When composting, it is necessary to pay attention to appropriately increase the proportion of hot fertilizer and reduce the amount of water and soil, so that not only the fermentation is fast, but also the quality is good.
Antifreeze
Winter manure piles are easily frozen and affect the quality. The fertilizer pile should be properly increased, so that the heat is slowly emitted and is beneficial to fermentation. In addition, in order to speed up the fermentation of frozen fertilizer, you can plan a pit in the fertilizer pile (two can be planed for large piles), weeds are piled up in the pit, and then the smoke is ignited and slowly smoked, but care should be taken not to burn the grass. .
4. Seal
Cover the soil around the pile with straw, so that it forms a 30-50 cm thick insulation layer, then the mud is closed, and the condition can also cover the waste plastic film insulation.
