Problems solved by technology

On slopes with sparse vegetation, P nutrients are easily eluted by runoff into surface water bodies and groundwater, resulting in eutrophication of water bodies, which is not conducive to environmental protection. Nutrient abundance, plant growth and microbial biomass carbon are all severely affected, creating a vicious cycle

Abstract

The invention discloses an environment-friendly soil amendment which is prepared from the following components including ferrous sulfate, polyacrylamide, potassium humate, polyglutamic acid, spirulina, a silicate microbial agent, a carrier and feces and is prepared by the following steps of performing fermentation on the silicate microbial agent, the carrier and a nitrogen-free medium firstly to form a high-activity and high-density flora; mixing the flora and the feces for secondary fermentation; and uniformly mixing the other nutrients and a secondary leavening. The environment-friendly soilamendment has the advantages that through combination of the three of the polyacrylamide, the ferrous sulfate and the potassium humate, loss of P in soil can be reduced, microbial biomass carbon is increased at the same time, so that plants can acquire enough nutrients; and meanwhile, the microbial agent can be combined with heavy metals in the soil to form a complex, so that absorption of the plants to the heavy metals is reduced, the growth condition of the plants is improved, pollution of the heavy metals to crops is lowered, and the yield of the crops is increased.

Description

technical field [0001] The additive for improving soil fertility of the invention particularly relates to an environment-friendly soil conditioner. Background technique [0002] Soil fertility is one of the most important factors affecting plant growth. Fertilization is a common means of enhancing soil fertility, but it is not enough to ensure that plants can get enough nutrients by applying a large amount of elements needed for plant growth. Under the dissolution and erosion of runoff, the nutrients in the soil will be lost. On slopes with sparse vegetation, P nutrients are easily eluted by runoff into surface water bodies and groundwater, resulting in eutrophication of water bodies, which is not conducive to environmental protection. Nutrient abundance, plant growth and microbial biomass carbon are all severely affected, creating a vicious cycle. In addition, heavy metal pollution is a major problem for plant growth and food safety. It is necessary to reduce the adverse...
