Soil Improvement
Targeted Treatment for Desertification, Salinization, and Gobi Desertification Desertified Land
Windbreak and Sand Stabilization: Lay grass grids and sod, planting drought- and cold-resistant plants (such as seabuckthorn, goji berries, blueberries, saxaul, and lemon saltbush) outside the grids to reduce wind erosion.
Increase Organic Matter: Apply organic fertilizers, straw, and wood ash to the soil, and use slash-and-burn methods to improve soil organic content.
Salinized Land
Salt Leaching Treatment: Use freshwater irrigation and deep soil soaking, combined with leaching to remove salts.
Chemical Improvement: Apply gypsum to neutralize sodium ions and improve soil structure.
Plant Salt-Tolerant Crops: Plant salt-tolerant species, such as alkali-weed and saltbush.
Gobi Desertified Land
Soil Covering and Improvement: Use straw, plastic film, or shading nets to cover the soil surface, reducing moisture evaporation.
Irrigation: Construct water channels to introduce water and improve soil moisture content.
Soil pH Adjustment
Acidic Soil Improvement
Lime Application: Apply an appropriate amount of lime per acre to raise the pH level.
Increase Organic Fertilizer: Organic fertilizers can improve soil buffering capacity.
Alkaline Soil Improvement
Ammonium Sulfate and Sulfur Powder: Apply to lower the soil pH.
Green Manure Cropping: Plant green manure crops and incorporate them into the soil to increase organic matter.
Normal Soil Maintenance
Balanced Fertilization: Apply nitrogen, phosphorus, and potassium fertilizers based on soil nutrient conditions.
Crop Rotation and Fallowing: Practice crop rotation and periodic fallowing to maintain soil fertility.
Precautions
Fertilizer Control: Avoid excessive use of chemical amendments to prevent secondary salinization.
Monitoring and Adjustment: Regularly monitor soil pH and nutrient levels, adjusting improvement methods as necessary.
