Green manuring is a sustainable agricultural technique that consists of growing certain species of plants with the objective of improving soil structure and health. These plants, known as "cover crops," are planted specifically to be incorporated into the soil after growth to make it more productive.
Species suitable for the creation of green manure cover crops.
- Legumes Nitrogen fixation in the soil.
- Grasses They help to maintain the soil structure.
- Cruciferae They attract beneficial insects and help natural pest control.
Why use green manure?
Improves Soil Structure
The roots of green manure plants help aerate the soil and prevent soil compaction, which favors water penetration and subsequent crop growth.
Increased nutrients
There are species such as leguminous plants that, when cultivated, fix nitrogen in the soil, increasing natural fertility and avoiding the use of chemical fertilizers.
Weed Control
Their rapid and high germination capacity reduces the presence of other unwanted species.
Increased organic content
When incorporated into the soil and decomposed, these plants provide organic matter, creating and favoring the presence of beneficial microorganisms as well as increasing water retention capacity.
Prevent erosion and loss of fertile soil
How to implement a green manure cover
- Selection of appropriate species according to climate and soil of the area.
- Sow at the right time and in periods not used by other crops.
- Incorporate selected plants into the soil before or during flowering to maximize benefits.
Incorporating agricultural practices such as the use of green manure not only improves crop productivity, but also contributes to a more integrated and sustainable agriculture for future generations.
