Sustaining agricultural productivity and soil health under intensive cultivation requires a comprehensive understanding of fertilization effects, particularly on deeper soil layers, which has received limited attention compared to surface soils. This study investigated how different fertilization regimes (inorganic, organic, and combined organic–inorganic fertilizers) influence soil ...

2、Organic fertilization promotes crop productivity through changes in

Agricultural fertilization is one of the most well-known drivers for increasing soil aggregation (Abiven et al., 2009; Bronick and Lal, 2005). The input of organic fertilizers such as compost derived from dung increases the physical protection of organic matter through enhancing macro-aggregate formation (Jiang et al., 2013; Singh, 2018).

3、How Organic Matter Influences Soil Fertility

This article delves into how organic matter influences soil fertility, exploring its composition, functions, benefits, and management practices to optimize soil productivity.

Soil Organic Matter and Its Impact on Soil Properties and Nutrient

Organic matter determines larger part of soil and has tremendous ecological significance; it influences ecosystem productivity, soil health, and climate quality. The soil organic matter maintains and improves many physical, chemical, and biological properties.

How Organic Matter Enhances Soil Fertility

Want to know what happens when organic materials like leaf litter, bark, or wood chips are added to soil? In this blog post, I explain the process and impact of organic matter on soil fertility.

THE IMPORTANCE OF SOIL ORGANIC MATTER (SOM) ON SOIL PRODUCTIVITY AND

Agricultural management of soils has led to severe losses of soil organic matter (SOM), accompanied by an increased release of CO 2 into the atmosphere and a reduction of soil fertility.

Organic fertilizer enhances soil aggregate stability by altering

Both soil organic carbon (SOC) and iron (Fe) oxide content, among other factors, drive the formation and stability of soil aggregates. However, the mechanism of these drivers in greenhouse soil fertilized with organic fertilizer is not well understood.

The Impact of Organic Matter on Soil Structure and Fertility

Organic matter significantly enhances soil structure and fertility. It improves soil aggregation, which increases porosity and aeration, allowing for better water infiltration and root penetration.

The Central Role of Soil Organic Matter in Soil Fertility and Carbon

Soil organic matter, its stable components (humic substances) and its transient components can strongly improve nutrient availability and acquisition by higher plants. Soil organic matter also strongly affects nutrient storage and its availability in soils.

Role of Organic Fertilizers in Improving Soil Fertility

Biofertilizers enhance soil fertility by adding organic matter to the soil that acts as binder for the soil particles together, preventing soil erosion, eructing, and desertification.

Organic matter is a critical component of soil fertility. It not only provides essential nutrients for plants but also improves soil structure, enhancing water retention and nutrient-holding capacity. increasing soil fertility by boosting organic matter content is a key task in modern agricultural production. Below are some recommendations for improving soil fertility and organic matter content:

1. Apply Organic Fertilizers Organic fertilizers, such as animal manure, compost, and green manure, are rich in organic material. Their application effectively increases soil organic matter, improves soil structure, and enhances water retention and nutrient-holding capacity. Additionally, microorganisms in organic fertilizers promote plant growth, increasing crop yield and quality.

2. Practice Crop Rotation and Intercropping Crop rotation and intercropping reduce pest and disease risks while enhancing soil fertility. These practices allow soil nutrients to cycle efficiently, preventing imbalances caused by monocropping. Different crops have varying soil requirements, so rotating or intercropping helps avoid overexploiting specific nutrients, maintaining stable soil fertility.

3. Deep Till the Soil Deep tillage is vital for improving soil fertility. It exposes soil organic matter to air, enhancing aeration and permeability, which fosters microbial activity and root growth. Deep tillage also breaks up compacted soil, improving water retention and nutrient availability.

4. Incorporate Green Manure Green manure, such as leguminous plants (e.g., soybeans) and alfalfa, adds organic matter to the soil. Planting these crops increases soil fertility, improves water retention, and enhances soil structure by promoting aeration and permeability.

5. Irrigate Rationally Balanced irrigation is essential for maintaining soil fertility. Excessive irrigation reduces soil aeration and fertility, while appropriate watering supports healthy plant growth. Rational irrigation also minimizes pest and disease risks, improving crop yield and quality.

6. Fertilize Scientifically Optimal fertilization is crucial. Overfertilization raises soil salinity, harming plants, while proper nutrient application meets plant needs and boosts soil fertility. Scientific fertilization also increases organic matter and improves soil structure.

7. Use Biological Pest Control Biological pest control, leveraging beneficial insects and microorganisms, suppresses soil pathogens and reduces chemical pesticide use. This eco-friendly approach enhances soil fertility and promotes plant health.

8. Apply Soil Amendments Soil amendments like lime or gypsum adjust soil pH, improve fertility, and enhance aeration and permeability. These changes support microbial activity and root development.

9. Monitor Soil Health Regular soil testing for nutrient levels, pH, and microbial activity helps detect fertility changes early. Timely adjustments and repairs ensure sustained soil health.

improving soil fertility and organic matter requires integrating multiple strategies: organic fertilization, crop rotation, deep tillage, green manuring, rational irrigation, scientific fertilization, biological pest control, soil amendments, and continuous monitoring. These combined efforts foster agricultural sustainability and resilience.
