1. the so-called organic fertilizer is used widely in the nature of the distribution of microorganisms, under controlled conditions, the organic components in waste is not stable to decomposition, converted to stable humus composition, namely compost.
2. characteristics of humic substances
2.1 the color is dark brown to black, the soil color is deep, helps absorb heat to maintain the temperature, promote crop growth.
2.2, the surface area ratio is large, can absorb a lot of water, so that volume expansion, and help soil water retention
2.3 can adsorb large amounts of cations and anions, which can buffer soil pH and salinity.
2.4, humus, cohesion, plasticity and viscosity are not strong, making the soil loose, conducive to water infiltration, soil cultivation and reduce plant root growth resistance.
2.5 to promote soil mass (aggregation), so that the soil ventilation and water permeability is good, suitable for plant root growth, and reduce erosion.
2.6 humic substances in the soil, continuous release of nitrogen, phosphorus, potassium and other nutrients necessary for plant growth and development.
Organic fertilizer effect
Organic fertilizer containing microorganisms and rich source of nutrients, soil can be directly absorbed by plants, or by microorganisms and other biological activity and metabolism, penetration into effective ingredients for plant absorption use.
Organic matter organic fertilizer rich in a large number of available soil microbial population growth needs the source of nutrition, promote soil microbial community activity, maintain the balance of ecological environment.
•To improve the soil properties, reduce soil stickiness, prevent soil plate section, soil mass dies tectonic stability, soil fertility, water holding ability, ability of ventilation, promote crop root development, improve the utilization rate of water and nutrient.
- by organic matter decomposition and microbial metabolism, have to plant growth substances, including organic acids, nucleic acids, vitamins, antibiotics, amino acid, He Ermeng, the plants with insect resistance, disease resistance, resistance to bad weather strength, improve the quality and quantity of production.
- in the decomposition of soil acid, chemical fertilizer, pesticide and some harmful substances, and released for use of plant nutrient elements in the soil, promote the growth of plants.
- can provide a lot of buffer capacity, enhanced soil pH and soluble salt for 2 types, organic pollutants, harmful heavy metal and other pollutants load capacity, reduce the crop suffer harm the scale.
