Liquid fertilizer for soil improvement

Abstract

The invention discloses a liquid fertilizer for soil improvement. The liquid fertilizer for soil improvement comprises the following components in percentage by weight: 5 to 15 percent of sugar alcohol, 20 to 35 percent of nitrogen fertilizer, 10 to 20 percent of phosphorus fertilizer, 5 to 15 percent of potassium fertilizer, 20 to 30 percent of organic acid and the balance of water. According to the liquid fertilizer for soil improvement, provided by the invention, through reasonable proportioning correspondence of the sugar alcohol, the nitrogen fertilizer, the potassium fertilizer, the phosphorus fertilizer and the organic acid, the sugar alcohol and the elements such as potassium, calcium and magnesium form a stable compound, so that the liquid fertilizer can promote crops to absorb nutrients, the soil environment is improved, the utilization rate of the fertilizer is increased and the quality of the crops is improved; meanwhile, the organic acid can adjust the pH value of the soil and can promote release of the phosphorus in the soil, and the phosphorus can be compounded with heavy metal ions in the soil to form the stable compound, so that the soil environment is improved, the utilization rate of the fertilizer is increased, and the quality of the crops is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a liquid fertilizer for soil improvement. Background technique [0002] Soil is the substrate for crop growth, and the quality of soil is the key to the quality of crop growth. There are three kinds of problems in my country's current soil environment: 1) the nutritional ratio of nitrogen, phosphorus and potassium in the soil is out of balance; 2) residual pollution from excessive use of chemical fertilizers; 3) soil structure is damaged and hardened. The root cause of the above soil environmental problems is that the utilization rate of fertilizers is low, resulting in fertilizer residues in the soil, reducing soil permeability, and reducing the ability of crop roots to absorb nutrients in the soil. [0003] In order to solve the above problems, the method commonly used at present is to add organic acid to the fertilizer, which can adjust the pH of the soil, increase the pe...

AI Technical Summary

Problems solved by technology

The following three problems exist in my country's current soil environment: 1) The nutrient ratio of nitrogen, phosphorus and potassium in the soil is out of balance; 2) The residual pollution of excessive use of chemical fertilizers; 3) The soil structure is damaged and hardened

However, adding organic acids to fertilizers does not improve the soil environment significantly. After a period of time, there are still problems such as poor soil permeability.
