Types and Effects of Soil Conditioners

Soil conditioners reduce soil erosion, soil crusting, nutrient loss and soil erosion by improving soil structure and soil viscosity. The role of soil conditioner mainly focuses on the following points: first, to improve soil pH so as to achieve a suitable growing environment for crops; second, to improve the physical properties of soil to enhance the ability of soil water retention, soil retention and fertilizer retention; third, to increase the activity of beneficial microorganisms and enzymes in the soil, inhibit pathogenic microorganisms and enhance the effect of plant resistance; fourth, to reduce the migration capacity of heavy metal elements such as Cd and Pb in heavy metal polluted soil and inhibit the uptake of heavy metals by crops. Different soils should use different soil conditioners according to local conditions.

1, Alkaline Soil Conditioning Agent and Its Preparation Methods and Use
The conditioner belongs to the technical field of fertilizer consumption and is made of charcoal, dried pine needles, vermiculite, natural zeolite, humus, well-rotted farm manure, aluminum sulfate, zinc sulfate and manganese sulfate. The conditioner can loosen the soil of alkaline farmland, improve the physical and chemical properties of alkaline farmland soil, promote crop growth, improve the utilization rate of fertilizer and increase crop yield.

2, Nutrient-Based Orchard Acidified Soil Conditioner and Its Preparation Method and Use
The raw material components of the conditioner are fly ash, slag, calcium carbonitride, urease inhibitor, general calcium, magnesium, phosphorus and potassium fertilizer, zinc oxide and refined bentonite. This preparation method is simple, suitable for apple, pear and other orchards of acidified soil improvement, can improve the efficiency of fertilizer utilization; can also be used as a carrier, become a microbial conditioner or mixed with inorganic substances fermented into inorganic fertilizer with high nitrogen content, increase the number of populations of beneficial soil microorganisms; can significantly increase fruit yield and improve crop quality.

3, Coal Gangue Compound Soil Conditioner and Production Process
The raw material components of the conditioner include gangue, sodium hydroxide, used polyurethane foam, phosphoric acid, potassium chloride, urea and so on. Foam hardened into particles, the foam particles, gangue and sodium hydroxide neutralization and reaction of the material, potassium chloride, urea in turn added to the mixer, stirring and adsorption of the particles made into the converter drying that made, widely used in sand ginger black soil, sandy soil, white pulp soil, etc. improvement, with the dual role of improving and fertilizing the ground.

4, Mushroom Making Base Waste Used as Soil Conditioner
The conditioner is made of wheat straw, horse manure, chicken manure, soybean meal, grass charcoal, gypsum powder and other raw materials mixed with mushroom making material after the application of mushroom making base waste, after low temperature sterilization indirectly used as a conditioner or by low temperature sterilization, and then used as a soil conditioner after natural fermentation by deposition. The soil conditioner can not only reduce the pollution of the waste to the environment, but also make full use of the waste so that it can become an important source of fertilizer to promote crop growth and improve crop yield and quality.
