Healthy soils support abundant and diverse soil biota, contributing to overall soil fertility and ecosystem resilience. Practices such as reduced tillage, cover cropping, and organic matter addition can promote soil biota diversity and activity, improving soil health and productivity.


Green Manure Seeding

Green manure seeding is a practice in agriculture where specific plant species, known as green manure crops, are sown into the soil with the intention of improving soil fertility, structure, and health. These crops are typically grown for a certain period and then incorporated into the soil, where they decompose and release nutrients, organic matter, and beneficial microorganisms.

The process of green manure seeding involves selecting suitable cover crops that contribute to soil improvement, such as legumes like clover, vetch, or peas, which fix nitrogen from the air into the soil. Other non-leguminous plants like rye, oats, or buckwheat are also commonly used for their ability to add organic matter and improve soil structure.

Green manure seeding is usually timed to coincide with periods when the land would otherwise remain fallow, such as during winter or between cash crop seasons. The cover crops are planted densely to suppress weed growth and maximize biomass production. Before the main crop is planted, the green manure crops are either cut down and left on the soil surface as mulch or tilled into the soil to decompose.


How To Measure Soil Fertility

Measuring soil fertility involves assessing various factors that contribute to a soil’s ability to support plant growth and sustain agricultural productivity. Here are some common methods used to measure soil fertility:

Causes And Effects Of Decreased Fertility In The Soil


Nutrient Depletion: Continuous cropping without adequate nutrient replenishment leads to depletion of essential nutrients in the soil, such as nitrogen, phosphorus, and potassium.

Soil Erosion: Erosion removes the topsoil layer rich in organic matter and nutrients, reducing soil fertility over time.

Soil Compaction: Heavy machinery and foot traffic compact the soil, reducing pore space and limiting root growth, nutrient uptake, and water infiltration.

Acidification: Acid rain, excessive use of acidic fertilisers, and certain agricultural practices can lower soil pH, inhibiting nutrient availability and microbial activity.

Salinization: Irrigation with saline water or poor drainage can lead to salt accumulation in the soil, causing toxicity to plants and disrupting soil structure.



Reduced Crop Yields: Decreased soil fertility results in poor plant growth, lower yields, and decreased agricultural productivity.

Nutrient Deficiencies: Plants grown in nutrient-deficient soils exhibit symptoms such as stunted growth, yellowing leaves, and reduced fruit or seed production.

Loss of Soil Structure: Soil with decreased fertility is often compacted, eroded, and lacks proper aggregation, leading to poor water infiltration, increased runoff, and susceptibility to erosion.

Increased Input Costs: Farmers may need to apply more fertilisers, pesticides, and water to compensate for poor soil fertility, leading to increased production costs and environmental impacts.

Erosion and Land Degradation: Soil erosion and degradation worsen as soil fertility declines, leading to loss of arable land, decreased biodiversity, and adverse environmental consequences.


How to Increase Fertility in Soil

Soil Testing: Begin by conducting soil tests to assess nutrient levels, pH, and other soil properties. This information helps tailor fertility management practices to specific soil needs.

Cover Cropping: Plant cover crops during fallow periods to protect the soil surface, reduce erosion, and add organic matter. Select cover crops based on their ability to fix nitrogen, scavenge nutrients, or suppress weeds.

Crop Rotation: Rotate crops to break pest and disease cycles, enhance soil nutrient diversity, and improve overall soil health. Different crops have varying nutrient demands and root structures, which can benefit soil fertility when rotated.

Nutrient Management: Apply fertilisers judiciously based on soil test results and crop nutrient requirements. Use slow-release fertilisers, organic amendments, or precision application techniques to minimise nutrient losses and improve efficiency.

Mulching: Apply organic mulches such as straw, leaves, or grass clippings to the soil surface to conserve moisture, suppress weeds, moderate soil temperature, and gradually release nutrients as they decompose.

Water Management: Implement efficient irrigation practices to maintain optimal soil moisture levels for plant growth while minimising water runoff and leaching of nutrients. Proper drainage management prevents waterlogging and salinization issues.


Crop Rotation

Crop rotation is a farming practice where different crops are grown sequentially on the same piece of land over time. It involves alternating the types of crops planted in a specific field, typically following a planned rotation schedule. Here’s how crop rotation works and its benefits:

Diversification: Crop rotation helps diversify the types of plants grown on a farm, which can break pest and disease cycles. Different crops have varying nutrient needs, root structures, and growth habits, which can help improve soil health and fertility.

Pest and Disease Management: Planting different crops in succession disrupts the buildup of pests and diseases that target specific crop species. Rotating crops can reduce the need for pesticides and fungicides, leading to more sustainable pest management practices.

Nutrient Management: Different crops have different nutrient requirements. Crop rotation allows for more efficient use of soil nutrients, as crops with varying nutrient needs are grown in succession. For example, legume crops can fix atmospheric nitrogen, replenishing soil nitrogen levels for subsequent crops.

Soil Health: Crop rotation can improve soil structure, increase organic matter content, and enhance microbial diversity in the soil. Certain crops, such as cover crops or deep-rooted plants, can help break up compacted soil and improve soil aeration and drainage.

Weed Control: Crop rotation, especially when combined with cover cropping, can help suppress weed growth by disrupting weed life cycles and competing for resources. This can reduce the need for herbicides and mechanical weed control methods.

Yield Stability: Rotating crops can help stabilise yields by spreading risk across different crops. If one crop fails due to unfavourable weather conditions or pest outbreaks, other crops in the rotation may still thrive, reducing the overall impact on farm income.


No-Till Farming

No-till farming revolutionises traditional agricultural practices by eliminating soil disturbance. Instead of ploughing or cultivating before planting, seeds are directly sown into tilled soil or onto crop residues from the previous harvest. This method conserves soil structure and organic matter, reducing erosion and preserving soil health. By keeping crop residues on the soil surface, no-till farming also enhances water retention, reduces evaporation, and promotes carbon sequestration, contributing to climate change mitigation efforts.

Furthermore, no-till farming minimises energy use and greenhouse gas emissions associated with tillage operations. Additionally, the presence of crop residues provides a protective cover for emerging seedlings, improving crop resilience to environmental stressors like drought and extreme temperatures. Overall, no-till farming represents a sustainable approach to agriculture that benefits both farmers and the environment.


Fertilization is a crucial aspect of modern agriculture, ensuring that crops receive the essential nutrients needed for optimal growth and productivity. Soil testing plays a key role in determining nutrient levels and pH balance, guiding farmers in selecting the right fertilizers and application rates. Various types of fertilizers, including synthetic, organic, and mineral supplements, offer different nutrient compositions and release rates. Applying fertilizers using appropriate methods, such as broadcasting, banding, or foliar feeding, helps maximize nutrient uptake by crops while minimizing nutrient runoff and leaching into water bodies.

Sustainable fertilizations practices aim to balance nutrient inputs with crop needs, promote nutrient recycling through organic matter decomposition, and minimize environmental impacts such as water pollution and soil degradation. By integrating fertilisation with other soil and crop management practices, farmers can maintain soil fertility, enhance crop yields, and support long-term agricultural sustainability.
