Vegetable manure is naturally essential for growing vegetables. Common types of manure include pig manure, sheep manure, cow manure, chicken manure, etc. So which type of manure is better? Pig manure and sheep manure have strong water and fertilizer retention abilities, significant soil loosening effects, and high organic matter content. Therefore, pig manure and sheep manure are the preferred manure for vegetable cultivation; Cow manure has a low organic matter content and is a cold fertilizer. After being applied to the soil, the release of nutrients is relatively slow, so cow manure is generally not used for vegetable cultivation.
Chicken manure is a manure with a high organic matter content, which is around 24%. After being applied to the soil, it can significantly enhance soil fertility. However, it is not recommended to use chicken manure for vegetable cultivation all year round. Firstly, due to the high organic matter content of chicken manure, incomplete decomposed chicken manure will release a large amount of heat when applied to the soil, which can easily cause plant root burning; Secondly, perennial application of chicken manure can easily lead to soil salinization and increase soil alkalinity, which seriously restricts soil permeability and activity; In addition, chicken manure that is not well fermented is particularly prone to breeding root knot nematodes. Root knot nematodes can bite the roots of crops, affecting their growth and development. For example, some chicken manure also has the problem of excessive heavy metals, so it is not recommended to use chicken manure for vegetable cultivation all year round.
