Green Leaf Manuring
Green manure is a type of organic fertilizer that is made from growing and then incorporating green plants into the SoilSoil. Green manure plants are typically legumes, such as alfalfa or clover, but they can also be non-legumes, such as buckwheat or mustard.

Plant Sources
Green leaf manuring utilizes readily available foliage from plants in the surrounding landscape:
- Trees and Shrubs: Leaves from a variety of trees and shrubs are suitable, with nitrogen-fixing species like acacia or glyricidia being particularly beneficial.
- Herbaceous Plants: Young, tender leaves from fast-growing herbaceous plants can be gathered for green leaf manure.
- Weeds (non-invasive): Before they flower and set seed, many common weeds are a valuable source of green material for enriching the soil.
Nutrient Content
- Nitrogen (N): Green leaves are a good source of nitrogen, the fuel for leafy growth in plants. The nitrogen content varies based on plant type, with higher levels found in young, fresh growth.
- Potassium (K): Green leaf manures supply potassium, essential for water regulation, disease resistance, and overall plant health.
- Other Micronutrients: Depending on the plant source, leaves contain a range of micronutrients, including calcium, magnesium, and iron, contributing to a more balanced nutrient profile in the soil.
Collection and Preparation
Ideally, collect young, succulent leaves and tender twigs. They decompose faster and have a higher nutrient concentration. Chopping or shredding the material before use speeds up the decomposition process further.
Application Methods
- Direct Incorporation: The collected green material can be directly tilled or dug into the soil, providing a readily decomposable source of nutrients.
- Mulching: Spread green leaves as a mulch around plants. As they decompose, they suppress weeds, conserve moisture, and gradually release nutrients.
- Composting Ingredient: Adding green leaves to a compost pile enriches the finished compost and helps balance the “brown” materials like dried leaves and wood chips.
Benefits of Green Leaf Manuring
- Soil Fertility Boost: Similar to traditional Green Manuring, incorporating green leaves releases nitrogen, potassium, and other nutrients, enhancing the soil’s overall fertility.
- Improved Soil Structure: As the green leaf material decomposes, it contributes organic matter to the soil, improving its structure, water-holding capacity, and aeration.
- Moisture Retention: Green leaf mulch helps conserve soil moisture around plants, reducing the need for frequent watering.
Potential Limitations
It’s important to avoid collecting leaves from poisonous or invasive plants, and there’s a risk of introducing weed seeds if using weeds as a source. In some cases, green leaf material can have an immobilizing effect on soil nitrogen temporarily, so adding supplemental nitrogen fertilizer might be needed.
Overall, green leaf manuring is a valuable practice, especially in areas with limited resources. It’s a simple, low-cost way to utilize plant matter for improving soil health and fertility, maximizing the use of Natural Resources within the agroecosystem.
Green manure plants are grown specifically to be turned into the soil, and they provide a number of benefits to the soil and to the plants that are grown in it. Green manure plants help to improve soil structure, increase soil fertility, and suppress weeds. They also help to improve water infiltration and drainage, and they can help to reduce soil erosion.
Green manure plants are typically grown in the spring or fall, and they are turned into the soil before they flower. This helps to prevent the plants from setting seed, which can become weeds in the future.
There are a number of different ways to incorporate green manure plants into the soil. One way is to simply chop the plants up and then till them into the soil. Another way is to mow the plants and then spread them on the soil as a mulch. Green manure plants can also be grown in a cover crop, which is a type of crop that is grown between Cash Crops. Cover crops help to protect the soil from erosion and to improve soil fertility.
Green manure plants are a valuable tool for farmers and gardeners, and they can provide a number of benefits to the soil and to the plants that are grown in it.
Benefits of Green Leaf Manuring
Green leaf manuring has a number of benefits, including:
- Improving soil structure: Green manure plants help to improve soil structure by adding organic matter to the soil. Organic matter helps to bind soil particles together, which makes the soil more stable and less likely to erode.
- Increasing soil fertility: Green manure plants help to increase soil fertility by adding nutrients to the soil. These nutrients can be used by plants to grow and produce a healthy crop.
- Suppressing weeds: Green manure plants can help to suppress weeds by competing with them for water and nutrients. This can help to reduce the number of weeds that need to be controlled with herbicides.
- Improving water infiltration and drainage: Green manure plants help to improve water infiltration and drainage by loosening the soil and creating pores. This allows water to enter the soil more easily and to drain more effectively.
- Reducing soil erosion: Green manure plants help to reduce soil erosion by holding the soil in place. This is especially important in areas that are prone to erosion, such as hillsides.
How to Use Green Leaf Manuring
Green leaf manuring can be used in a number of ways, including:
- IntercroppingIntercropping: Intercropping is a method of growing two or more crops together. Green manure plants can be intercropped with cash crops, such as corn or soybeans. This helps to improve soil fertility and to suppress weeds.
- Cover CroppingCropping: Cover Cropping is a method of growing a cover crop between cash crops. Cover crops help to protect the soil from erosion and to improve soil fertility.
- Green manure mulching: Green manure mulching is a method of spreading green manure plants on the soil as a mulch. This helps to improve soil structure and to suppress weeds.
- Green manure composting: Green manure plants can be composted to create a nutrient-rich compost that can be used to improve soil fertility.
