Description

Soil Conditioner for Growing Crops {A Soil Conditioner}

The present invention relates to a soil improvement agent for growing crops, and more particularly, to a soil improvement agent for growing a crop, which can maximize the improvement effect of the soil by spraying a small amount of microorganisms and functional materials into natural minerals.

Improving soil properties has been carried out as one of the methods for increasing harvest in agriculture. For this purpose, it is widely used to use soil with a high clay content to soil soil with exhausted land. However, when the above-mentioned method is employed, there is a problem that it is difficult to find a superior ground source, and when a superior land source is selected in another region, economical deterioration is accompanied by transport costs for carrying the ground.

Artificial chemical fertilizers and pesticides are increasingly used to solve the problem caused by such a ground. However, due to the use of chemical fertilizers and pesticides, the lack of special constituents (trace elements) in the soil, the base of the soil is melted and nutrient deficiency appears in the soil layer, and the soil is acidified so that the side effects . As a result, the quality of harvested crops is degraded, and problems arise due to the occurrence of various environmental pollution, and the resistance against use of chemical fertilizers and pesticides is spreading.

Recently, a soil improvement agent using natural mineral resources has been continuously developed for the purpose of preventing the acidification of the soil due to chemical fertilizer. Soil modifiers change the properties of the soil to the growth of crops in order to increase crop yield and quality. In addition, the soil conditioner is usually sprayed on acidified agricultural land to weaken or neutralize the acidity of the soil, and calcareous fertilizer is a typical example. The primary purpose of spraying lime on acidified agricultural land is to neutralize the soil and reinforce its intellect. However, when lime is used, lime penetrates between soils of the soil and gradually solidifies to block the pores of the soil, thereby deteriorating the air permeability, resulting in a side effect that the oxygen supply to the soil is not smooth. As a result, the respiration of the crops is disturbed by the spraying of the lime, which causes the soil to be disadvantageous to the growth of crops.
