💩 粪便

动物粪便用作有机肥料来改良土壤。

粪便

粪肥是动物粪便，通常与垫料稻草或尿液混合，用于改良土壤。农民们数千年来一直将其施用于田地，它至今仍是最全面的有机改良剂之一。

新鲜粪肥与堆肥粪肥截然不同。新鲜粪肥氨和盐含量高，会灼伤幼苗，而且可能携带病原体或杂草种子。经过堆肥或陈化处理，新鲜粪肥中的有害化合物被分解，许多病原体被杀死，最终形成稳定、疏松的肥料，既能增加土壤有机质，又能为作物提供养分。

类型和用途

粪便也是一个环境问题。来自农田和饲养场的径流会将磷和氮带入水道，导致藻类大量繁殖。避开雨季施用粪便，并将粪便混入土壤中，可以降低这种风险。

    The smell when it's being spread is intense but temporary. Results in the garden are worth it.

    Well-composted manure is gold for soil structure and nutrients. Fresh can burn plants though.

    Manure is a great fertilizer but it needs to be composted first. Fresh manure can burn plants.

    Horse versus cow versus chicken have different nutrient profiles. Matching to soil needs helps.

    My grandfather swore by horse manure for his garden. He had the best tomatoes in the neighborhood.
