What to do about the many harms of soil continuous cropping? Microbial fertilizer to the rescue
As China's agriculture develops faster and faster, the problem of continuous cropping has become increasingly serious, becoming a major disease in today's agriculture, sweeping across the country, causing crop root rot and dead plants, stunted development, and seriously affecting crop quality and yield, especially for high-value cash crops like ginseng. To avoid the harm of continuous cropping, farmer friends have no choice but to relocate their planting, wasting a great deal of cost.
Reasons why continuous cropping causes serious harm to crops:
Planting the same crop year after year causes soil-borne disease bacteria to gradually accumulate, leading to increasingly serious root rot and dead plants; at the same time, some organic matter that has not been fully decomposed will also cause the accumulation of nematodes; when carrying out soil disinfection, beneficial microorganisms in the soil are also killed, causing an imbalance in the soil microbial flora.
Because crops absorb relatively large amounts of certain nutrient elements, this leads to the deficiency of those elements in the soil layer; heavy application of nitrogen, phosphorus and potassium will also cause other trace elements in the soil to be fixed, causing nutrient deficiency symptoms in crops, lowering immunity, and making soil-borne diseases spread faster.
Due to years of continuous cultivation, the soil has accumulated excessive salt, which inhibits the crop's absorption of nutrients and water from the soil and has a toxic effect on crop roots.
During the growth process, crops produce an "autotoxicity phenomenon," that is, certain metabolites or decomposed chemical substances released into the area around the root system have harmful effects on individuals of the same crop species, often shown as weakened growth, reduced yield, and so on.
Effective ways to solve the continuous cropping problem:
Applying microbial fertilizer to soil with severe continuous cropping problems can solve the soil continuous cropping problem at its root.
Applying microbial fertilizer can greatly increase the content of live beneficial microorganisms in the soil. Through a series of their own life activities, these beneficial bacteria can kill or inhibit soil-borne pathogens, repair the soil microbial flora, and degrade the harmful substances secreted by plant roots due to the "autotoxicity phenomenon."
Applying microbial fertilizer can improve soil structure, activate trace elements that have been fixed in the soil, and promote crop absorption of nutrient elements, thereby improving crop resistance, achieving increased yield, and enhancing crop quality.
