Preparation and Application of a Composted Chicken Manure Composite Crop Substrate

The core ratio consists of 4 parts of ultra-high temperature composted chicken manure, 3 parts of biochar and 3 parts of vermiculite, and 0.5~1.5 parts of wood vinegar can also be added to enhance the effect. Ultra-high temperature composted chicken manure overcomes many drawbacks of traditional composting.

This composite substrate has excellent physical and chemical properties. When applied to the seedling raising of tomatoes and rice, it can significantly improve plant height, stem diameter, biomass and other growth indicators compared with commercial substrates, and exhibits excellent seedling emergence rate and strong seedling index. In addition, it realizes the resource utilization of solid waste, which is both economical and environmentally friendly.
