1. Green Manuring For Horticulture Production

2. Green Manuring Green manuring is a part of organic farming which can be defined as” the practice of ploughing or turning of undecomposed green plant tissue into the soil for the purpose of improving physical structure as well as fertility of soil.

4. Methods Of Green Manuring Basically green manure is prepared in 2 ways. Such as: In-Situ Green Manuring : In this system the short duration suitable crops are grown in a field prior to crop cultivation and then cut and buried in the same site when approximately 50% of all plants are flowering. Ex-Situ Green Manuring: Green leaves and tender plant parts of the plants are collected from shrubs and trees growing on bunds, degraded lands or near by forest and they are incorporated or mixed into the soil 15-30 days before sowing of the crops depending on the tenderness of the foliage or plant part.

5. Why Green Manuring? Bangladeshi soils are deficient in Nitrogen and Phosphorus and there is hardly any soil from which yield can be obtained without fertilization .

6. Conclusion Green manuring is a cost-effective way to improve soil fertility and increase crop yields. It can be used to reduce the need for chemical fertilizers and to improve soil structure and microbial activity. Green manuring can also help to conserve water and reduce soil erosion. When green manuring, it is important to select the right crop for the right soil conditions and to ensure that the soil is well-prepared before planting. Green manuring can also be used in combination with other soil amendments, such as compost and manure, to further improve soil fertility and crop yields.
