Balanced composite fertilizer

Abstract

The invention discloses balanced composite fertilizer. The balanced composite fertilizer is prepared from the following raw materials in percentage by weight: 4 to 7 percent of calcium nitrate, 20 to30 percent of ammonium sulfate, 15 to 36 percent of potassium sulfate, 15 to 20 percent of calcium triple superphosphate, 10 to 25 percent of composted organic fertilizer and 0.05 to 1 percent of trace nutrient elements. The balanced composite fertilizer disclosed by the invention selects multiple acidic raw materials, can be used for improving alkaline soil, balancing the soil pH (Potential of Hydrogen), and is also capable of avoiding fertilizer efficiency loss caused by acid-base neutralization reaction generated after mixing of the raw materials; meanwhile, the composted organic fertilizeris added in composite fertilizer coarse fertilizer, not only abandoned coffee grounds, banana peel, egg shells, hay and the like can be subjected to waste utilization, but also nutrient elements in the balanced composite fertilizer can be increased, so that the nutritive value of the balanced composite fertilizer is increased, nutrients required by crops are balanced, and growth of the crops is promoted.

Description

technical field [0001] The invention relates to a balanced compound fertilizer and belongs to the technical field of chemical fertilizers. Background technique [0002] After a certain period of production until maturity, crops can produce fruits that are thousands of times heavier than their original seeds, and must absorb a large amount of nutrients from the soil or the surrounding environment. This type of nutrition includes two categories: organic nutrition and inorganic nutrition; the required amount The most are nitrogen, phosphorus, and potassium. Since the content of these three types of elements in the soil is far less than the growth needs of plants, it is usually supplemented by fertilization to meet the needs of plant growth, thereby achieving the purpose of increasing production and income; currently in the market Common fertilizers in the world, from single nutrient fertilizers to compound fertilizers, have different physical and chemical properties.

[0002] After a certain period of production until maturity, crops can produce fruits that are thousands of times heavier than their original seeds, and must absorb a large amount of nutrients from the soil or the surrounding environment. This type of nutrition includes two categories: organic nutrition and inorganic nutrition; the required amount The most are nitrogen, phosphorus, and potassium. Since the content of these three types of elements in the soil is far less than the growth needs of plants, it is usually supplemented by fertilization to meet the needs of plant growth, thereby achieving the purpose of increasing production and income; currently in the market Common fertilizers in the world, from single nutrient fertilizers to compound fertilizers, have different physical and chemical properties. In particular, compound fertilizers are often difficult to match raw material fertilizers due to factors such as high nutrient content and complex components, and occur during storage and use. Caking and nutrient release are unreasonable, which brings the problems of inconvenient application and low effective utilization rate to agricultural production
