Why does modern agriculture encourage the increase of potassium humate fertilizer input?

 

The application of potassium humate is a comprehensive solution to modern agricultural soil degradation, resource waste and environmental pollution. It not only improves crop yield and quality, but also repairs the ecosystem, which is in line with the global strategy of sustainable development. In the future, with technological progress and cost optimization, its application potential will be further released.

 

1. Improve soil health and structure

Alleviate soil degradation: Long-term use of chemical fertilizers leads to soil compaction, organic matter loss, and reduced microbial activity. Potassium humate is rich in humic acid, which can promote the formation of soil aggregate structure, enhance air permeability and water and fertilizer retention capacity.

Activate nutrients: Humic acid can chelate with mineral elements (such as phosphorus, iron, and zinc) in the soil, reduce nutrient fixation, and improve fertilizer utilization.

Regulate acid-base balance: Potassium humate can buffer soil pH, alleviate acidification and salinization problems, and is especially suitable for farmland with long-term continuous cropping.

 

2. Improve crop stress resistance and yield**

Promote root development: Humic acid stimulates root growth and enhances water and nutrient absorption capacity, especially in drought or poor soil.

Enhance stress resistance: Potassium is a key element for plant disease resistance, cold resistance, and drought resistance. Humic acid can activate the plant enzyme system and synergistically improve the tolerance of crops to adversity (such as high temperature, pests and diseases).

- Increase yield and improve quality: Potassium humate can promote photosynthesis, fruit enlargement, and sugar accumulation, and improve the appearance, taste, and nutritional value of agricultural products.

 

3. Reduce environmental pollution and resource waste

Replace some chemical fertilizers: Potassium humate, as an organic-inorganic compound fertilizer, can reduce the use of traditional chemical fertilizers (such as urea and potassium chloride) and reduce the risk of eutrophication of water bodies caused by excessive fertilization.

Fix heavy metals: Humic acid can combine with heavy metals (such as cadmium and lead) in the soil, reduce their bioavailability, reduce the absorption of heavy metals by crops, and ensure food safety.

Resource recycling: Potassium humate is mostly derived from natural humus or industrial and agricultural waste (such as lignite, straw), which is in line with the concept of circular economy.

 

4. Responding to sustainable agricultural policies**

 

Policy orientation: Policies such as "zero growth of chemical fertilizers" and "organic fertilizer substitution" are promoted globally. Potassium humate, as an environmentally friendly fertilizer, is in line with the development trend of green agriculture.

 

Market demand: The growing demand for organic and pollution-free agricultural products by consumers promotes the adoption of safer fertilizer technology at the planting end.

 

5. Optimization of economic benefits

 

- Long-term cost reduction: Although the initial investment of potassium humate may be high, its effect on improving soil is cumulative, which can reduce the use of chemical fertilizers and soil remediation costs in the long run.

 

Multifunctionality: One fertilizer can be used for multiple purposes (potassium supplement, organic matter supplement, soil improvement), reducing the cost of farmers purchasing multiple fertilizers.
