Introduction

Soil degradation is a global challenge affecting agricultural productivity and environmental sustainability. Fortunately, specific fertilizers can play a crucial role in soil restoration by replenishing nutrients, improving soil structure, and introducing beneficial microorganisms. This article explores how various fertilizers can address common soil problems including poor fertility, acidification, salinization, and contamination.

Types of Restoration Fertilizers

• Organic Fertilizers(composted straw, animal manure): Enhance soil organic matter content, improve soil aggregation, and increase water retention capacity while providing energy for soil microorganisms.
• Microbial Fertilizers(nitrogen-fixing bacteria, phosphate-solubilizing bacteria): Activate fixed nutrients in soil through microbial metabolism, suppress harmful pathogens, and restore soil microecological balance.
• Conditioning Fertilizers(humic acid, amino acid fertilizers): Regulate soil pH, alleviate acidification or alkalization, reduce heavy metal ion activity, and minimize crop uptake of contaminants.
• Mineral-based Fertilizers(zeolite, bentonite): Adsorb heavy metals and excess salts through their porous structure while improving soil aeration and permeability.

Restoration Methods for Specific Soil Issues

Poor Soil Fertility

Apply organic fertilizers as the primary treatment (2000-3000 kg per hectare) combined with chemical fertilizers containing nitrogen, phosphorus, and potassium. Incorporate deeply through plowing to gradually increase organic matter content. Avoid single-nutrient fertilization to prevent nutrient imbalance.

Soil Acidification (pH < 5.5)

Use humic acid fertilizers or alkaline conditioning fertilizers (50-100 kg per hectare) accompanied by irrigation to help neutralize soil acidity. Limit the long-term use of acidic chemical fertilizers like ammonium sulfate.

Soil Salinization (EC > 2 mS/cm)

Increase application of organic and microbial fertilizers. The organic acids released during decomposition help reduce salt concentration. Implement drip irrigation with frequent, small applications to leach surface salts while reducing chemical fertilizer usage.

Soil Compaction

Focus on organic fertilizers and crop residue incorporation. Apply 500-1000 kg of crushed straw per hectare combined with deep plowing to break up compacted layers. Reduce tillage intensity to preserve soil structure.

Heavy Metal Contamination

Apply humic acid fertilizers or mineral-based amendments to immobilize heavy metals through adsorption. Combine with specific microbial inoculants that promote the transformation of heavy metals into stable forms, reducing crop uptake risks.

Important Considerations
