Enhancing soil health: humic acid organic fertilizer and biostimulants in agriculture

CAUSES AND EFFECTS OF SOIL ORGANIC MATTER REDUCTION

Soil organic matter is one of the key factors of soil fertility, and its reduction will lead to a decline in soil fertility and loss of ecological functions. The main reasons include unreasonable nutrient management, excessive use of chemical fertilizers, unscientific land management, and reduced input of organic fertilizers.

These factors not only deplete the nutrients in the soil but also reduce the carbon return index of the soil, thereby affecting the structure and function of the soil. To counter these effects, the use of biostimulants in agriculture can enhance soil health by stimulating natural processes that improve nutrient uptake and plant growth. Causes and effects of soil compaction.

Soil compaction is another serious degradation problem caused by factors such as heavy soil texture, shallow tillage layers, low input of organic materials, plastic waste pollution, single fertilization, soil structure damage from mechanical operations, accumulation of harmful substances, and soil erosion due to heavy rains. The use of biostimulants in agriculture can help alleviate soil compaction by enhancing soil structure and promoting healthier root systems.
