Abstract

The present invention relates to an organic calcium fertilizer based on contaminants and a method for producing the same. The pollutant means a substance containing a large amount of organic substances such as human manure, livestock manure, food waste, fish and shell waste.

Long-term application of chemical fertilizers to the soil will lead to acidification of the soil, leading to a loss of intelligence and weakening crop yields and pests. Therefore, recently, organic farming using compost instead of chemical fertilizer is encouraged, and lime is sprayed to neutralize or weakly alkaline the acidified soil with compost.

In view of the above, the present invention allows organic fertilizer to be obtained by mixing lime and contaminants at a constant ratio, and to obtain organic calcium fertilizer by mixing calcium oxide, which is quicklime, and contaminants in a certain ratio. .

Description

Organic Calcium Fertilizer and its Manufacturing Method

The present invention relates to an organic calcium fertilizer based on various pollutants that destroy the natural environment, and a method for producing the same.

The various contaminants mean manure, livestock manure and food waste, fish and shell waste. Long-term use of chemical fertilizers on the ground can lead to acidification of the soil and lessen its ability to reduce crop yields and pests. Therefore, in recent years, the situation is encouraging organic farming using compost instead of chemical fertilizer.

Compost is a state in which carbohydrates are depleted due to the decomposition and decomposition of fiber of plants, and its main component is corrosion, and it is a dark colored material. Such compost absorbs mineral colloids and makes the soil porous and slowly decomposes to release nutrients, improving the physical properties of the soil and restoring the soil's intellect.

In addition, in order to increase the content of organic matter in the composting compost by adding animal manure or by-products of fish and shellfish. In addition, lime is administered in order to transform acidified soil into neutral or weakly alkaline by prolonged administration of chemical fertilizers.

Thus, compost and lime is used as a soil reinforcing agent to restore the intellect by alkalizing the soil that has been acidified due to excessive use of chemical fertilizers.

Manure was the main fertilizer before the production of chemical fertilizers, but nowadays it has not been used as a fertilizer due to the problems of odor, toxicity, and collection, transportation, and storage.

However, the manure corresponds to an organic substance containing a large amount of organic substances such as nitrogen (N), phosphoric acid (P), potassium (K) and the like.

The composition table of livestock manure is as follows.

In addition to livestock manure, phosphate manure is being used as an environmental pollutant instead of being used as a fertilizer due to organic matter or odor, toxicity and difficulty in collecting, transporting and storing moisture and nitrogen, phosphoric acid and potassium. Not only livestock manure and phosphorus manure, but also food waste, fish and fish waste or by-products are organic substances, but they are not only difficult to collect and store, but also difficult to process as fertilizers. Is recognized.

The present invention has been devised to provide an organic calcium fertilizer having no odor in a short time from various organic ingredients and various pollutants.

Lime may be used to neutralize acidic soils or transform them into weakly alkaline. Lime used in farms uses calcium hydroxide [Ca (OH) ₂ ] and calcium carbonate [CaCo ₃ ]. Calcium hydroxide [Ca (OH) ₂ ] is a state in which physical properties are stabilized in the form of water added to calcium oxide [CaO] which is quicklime, and calcium carbonate [CaCo ₃ ] is a mixture of carbon dioxide [Co] in calcium oxide [CaO]. As a result, the physical properties are also stable.

Such calcium hydroxide [Ca (OH) ₂ ] and calcium carbonate [CaCo ₃ ] adsorb the acidic ions in the soil to change the soil from neutral to weak alkaline. However, quicklime calcium oxide [CaO] is an expensive and very unstable compound that reacts explosively, especially when reacted with water, and generates high heat, which is very dangerous. Therefore, calcium oxide [CaO] has conventionally been used in the form of the above-mentioned calcium carbonate [CaCo ₃ ] and calcium hydroxide [Ca (OH) ₂ ] rather than directly used as a fertilizer.

In the present invention, however, the calcium oxide (CaO) in such a dangerous state can be stirred and mixed with the powder or other contaminants which are the raw materials of the fertilizer to obtain an organic fertilizer.

The contaminants collected in the collection tank were stirred so that there was no lump, and then 30-50% by weight of contaminants and 40-60% by weight of calcium oxide (CaO) were stirred and mixed for about 30-50 minutes.

The pollutants include human manure, manure manure, pig manure, manure manure and livestock manure and livestock manure such as chicken, duck, goose, etc., means food waste and fish waste. Such various contaminants will increase or decrease the content of calcium oxide (CaO) according to the water content thereof.

In addition, in the above it may be prepared by administering 30-50% by weight of contaminants, 20-30% by weight of calcium oxide and 20-30% by weight of ocher soil in a stirring tank and then stirred and mixed for 30-50 minutes. The ocher soil is preferably a reddish clay, which is preferably administered in a powder state by crushing the lump before administering it to the stirring tank.

When calcium oxide (CaO) and manure are stirred and mixed in the stirring tank, the water (H ₂ O) contained in the contaminants is converted into calcium hydroxide (CaO) and calcium hydroxide [Ca (OH) ₂ ] and generates high heat. The reaction scheme is as follows.

CaO + H ₂ O → Ca (OH) ₂ + cal

Therefore, the moisture contained in the pollutant is naturally evaporated, and various bacteria contained in the pollutant are sterilized by the exotherm. In addition, the odor contained in the pollutant is extinguished by exothermic action and chemical reaction to obtain an odorless organic fertilizer.

Phosphorus manure or manure manure is a good fertilizer because it contains a large amount of organic matter, but because of its high toxicity and bad smell, it cannot be used directly as a fertilizer. In addition, food waste and fish waste are also rich in organic materials, which are excellent fertilizers, but if left unsettled by odor during rotting, they become environmental pollutants and destroy natural ecosystems and pollute the environment.

Contaminants such as food waste and various manure or fish and fish waste were long time to ferment or decay into fertilizer, so the rate of recycling food waste and various manure as fertilizer was very low.

However, when various pollutants containing a large amount of moisture are mixed with calcium oxide [CaO] to make it a fertilizer, it can be reproduced as a fertilizer within a short time (30 minutes-1 hours). Odor and moisture are removed to be in a state of easy storage and transport for a long time.

Various organic substances contained in such pollutants are reproduced as organic fertilizers by exothermic processes and chemical reactions, and various bacteria contained in contaminants are sterilized during exothermic processes. In addition, if the pollutant and the ocher soil are mixed together, the odor contained in various pollutants is adsorbed by the adsorption and cohesive force of the ocher soil, thereby making it easier to remove the odor. After spraying on the ground, the plant is in a good state to absorb.

This invention can be reproduced as organic fertilizer from pollutants such as nutrients, animal meal, food waste, fish and shell waste that have been used as environmental pollutants, and can be used as soil stabilizer to neutralize acidified soil with chemical fertilizer. It is a very useful invention.
