Description

Soil improver {SOIL CONDITONER}

The present invention relates to a soil improving agent that can improve soil properties.

The soil covers the earth's surface with a thin layer, and when the right amount of air and water is contained, it mechanically supports the plant, and also supplies some of the nutrients to the plant to grow the plant. The soil is mixed with weathered products of the rock and organic matter that is decomposed and decayed therein, and its properties can be changed by the action of climate, living organisms, and the like.

The soil can be largely divided into topsoil (表 토), subsoil (心土), matrix material (母 質 物) and the like depending on the depth. Among them, the topsoil is dark because of its high organic content and is a site for storing and supplying most of the nutrients and moisture absorbed and used by plants. The topsoil of the topsoil is closely related to the biodegradation of the soil. For example, soils lacking in large-scale reclamation projects or other soil works can be cut down to secure their shortages or by using artificial soils, but it is almost impossible to secure topsoil to convert them into soils capable of healthy plant growth. In other words, topsoil is a difficult resource to regenerate, and after a good topsoil is lost due to indiscriminate construction, or after the soil's origin is destroyed, it takes a long time and a lot of expense to reconstitute it.

Soil modifiers may be used to improve the physical and chemical properties of the soil to suit plant growth. According to the background art, compost (manure), rice straw, barley straw and the like, or chemical fertilizers were used as the soil improving agent. However, the soil improving agent according to the background art is poor in its ability to store moisture, so it is difficult to use it in places such as ultrathin or artificial ground. In particular, as in Korea, the soil moisture storage capacity is urgently required in the region where the rainfall is severely changed according to the season.

The present invention provides a soil improving agent capable of continuously supplying water to the soil and / or plants growing in the soil by having a moisture storage capacity.

The present invention also provides a soil improving agent capable of activating soil microorganisms.
