3. Green Fertilizer: Utilizing Legume Plants
Green fertilizer is a natural method of enriching soil by cultivating specific plants, particularly from the legume family. These plants are then buried, enhancing the soil as a sustainable fertilizer.
This technique significantly improves soil fertility and structure, promoting better plant growth. By integrating green fertilizer into farming practices, farmers can boost crop yields while maintaining environmental health and sustainability.
Suitable Plants for Green Fertilizer:
– Legumes (peanuts, mung beans, soybeans)
– Clover
– Alfalfa
– Crotalaria (orok-orok)
Implementation Steps:
– Select the area to be fertilized and prepare the soil as usual.
– Plant green manure seeds according to the type selected.
– Allow the plants to grow until the flowering phase or before producing seeds.
– Cut the plants and leave them on the surface of the soil for a few days.
– Bury the remaining plants into the soil by hoeing or using agricultural tools.
– Let the soil “rest” for 2-3 weeks before planting the main crop.
Benefits and Applications:
Green fertilizer is highly effective in boosting soil nitrogen levels, particularly when legume plants are used. This technique also contributes to enhancing soil structure, minimizing erosion, and promoting the activity of beneficial soil microorganisms, leading to improved soil health and fertility over time.
