Description

A maunfacturing method for soil conditioner comprising activated kaolin as an active ingredient}

  The present invention relates to a method for producing a soil improving agent based on active kaolin, and more particularly, to prevent the acidification of the soil when cultivating the crop, to give the soil to prevent pests and cold damage, and to prevent pests and cold It is to provide the minerals needed for growth.

  Soil modifiers are supplied to the soil of the arable land in order to make the soil of the arable land to the optimum lipids for cultivating a predetermined crop, such soil modifiers have been used in various forms.

  Conventionally, excessive use of pesticides and chemical fertilizers makes the soil more acidic, and the microbial activity in the soil gradually decreases, reducing the activity of microorganisms in the soil, and suppressing the generation of gases due to the lack of organic matter that microorganisms must break down. As a result, the small space in the soil was lost, and the soil's intellect was lost, thus adversely affecting crop growth.

  Therefore, in order to solve the above problems, in order to neutralize the soil, land has been used or lime or siliceous fertilizer or the like has been used as a soil improving agent.

  The present invention uses activated kaolin products to improve the use of known soil modifying agents, such as lime or siliceous fertilizers, and is expected to be a new dimension in the development of soil modifying agents. It is to provide a method for producing a soil improving agent used.

  However, when the soil is applied with conventional soil neutralizing agents as described above, it may cause side effects due to unaging soil, and when lime or siliceous fertilizer is used, lime or siliceous fertilizer particles enter between soil soil particles. Gradually solidified, due to the lack of oxygen in the soil is a problem that the soil loses intelligence and causes acidification, and because it adversely affects the growth of crops has not solved the fundamental problem.

  Ion exchange between soil particles and plant roots is just as important as photosynthesis and absorption in terms of vitalizing plant life.

  Cation and anion exchange mostly occur on the surface of fine organic or inorganic colloidal particles, such as clay or decaying plants. The colloidal particle surface provides a place for preserving inorganic ions such as calcium, potassium, sulfur, etc. in the soil to prevent the loss of inorganic ions due to inundation or rainfall. In this way, the inorganic ions are stored in the soil colloid or supplied to the colloid again through the addition of chemical fertilizer, lime, and compost plant residue.

  The present invention has been made to solve the above problems by activating the kaolin to give a porous by making a wide space in the soil to facilitate the distribution of air to increase the activity of microorganisms in the soil, activated kaolin Since the rich trace elements provided by the soil are present in the colloidal state with corrosion and are generally charged with anions, the soil colloids can adsorb cations and the adsorbed cations are absorbed and supplied to plants for crop growth. It prevents acidification of the soil from oyster shells activated to prevent soil acidification, and gives the intellect to the soil and at the same time, the far-infrared rays radiated from kaolin contribute to the increase of crop income by actively growing the roots of crops. Thereby more effective soil improvement To provide a soil amendment that can be expected is the purpose of the invention.

  In order to achieve the above object, the present invention has the following features.

  The present invention is characterized in that 70 to 90% by weight of the active kaolin in the form of 150 mesh particles, and 10 to 15% by weight of active oyster shell activated at a temperature of 850 ℃.

  In another aspect, the present invention is the drying step of drying the kaolin collected from domestic exposure for 10 to 15 days, and the grinding step of grinding the dried kaolin to about 150 mesh by a dense (Jor mill), and the crushed kaolin An active step of firing at a temperature of 500 ℃ to activate a wide pore area on the surface, and a washing step to remove salt from the oyster shells taken from the beach, and in the firing furnace to develop pores on the surface of the washed oyster shells as possible It is characterized by consisting of a mixing step of activating by firing at a temperature of 850 ℃ for 40 ~ 60 minutes, and mixing each of the processed activated kaolin and active oyster shell in a mixer.

The kaolin is a typical mineral unique to clay that has been developed and used for the longest time in Korea, and the general formula is represented by SiAl ₂ O ₅ (OH) ₄ . Although clay minerals have been developed and used for the longest time in Korea, they have been applied mainly to ceramics, refractory fillers, and building materials by simple processing due to the lack of awareness of technology development due to the small size of domestic manufacturers.

The kaolin is mainly composed of silicic anhydride (SiO ₂ ) and aluminum oxide (Al ₂ O ₃ ), which are trace elements necessary for the growth of crops (Ca), magnesium (Mg), potassium (K), sodium (Na), and germanium. (Ge) and the like, the processed activated kaolin is formed on the surface of the pore area is wide, so that the air in the soil smoothly and radiates a lot of far infrared rays. Far infrared rays radiated by activated kaolin activate the water molecules in the soil to grow the roots of the crops actively, contributing to the increase of crop income.The germanium (Ge) contained in the kaolin is absorbed by the crops and converted into organic germanium. Since humans consume organic germanium in crops, they contribute to the health of the body by activating cells in the body.

  The oyster shell was collected from the seashore to go through the washing step to remove the salt to produce an active oyster shell activated by firing at 850 ℃ for 40 to 60 minutes in the calcination furnace to develop the pores on the surface of the oyster shell. The kaolin was collected by exposure and subjected to sun drying for 10 to 15 days, and then pulverized to about 150 mesh by a pulverizer to prepare activated kaolin activated by firing at 500 ° C. in a kiln to form a wide pore area on the surface of kaolin. . The activated kaolin and the activated oyster shell were mixed in a mixer to complete a soil improver for inhibiting acidification of the soil.
