The Effect of Citric Acid on Soil Improvement
Citric acid is a food additive, complexing agent, masking agent, has a strong buffering effect. In agriculture, it is mainly used as soil acid-base regulator and soil salinity improver. It has unique effect and remarkable efficacy.
Citric acid alleviates soil salt damage and is an excellent complexing agent, masking agent and has a strong buffering effect.
Soil salt damage, which can also be referred to as soil salinization, is the process by which salt capillary water from deep soil water rises to the surface and water evaporates, causing salts to accumulate in the surface soil. In the surface soil these salts include sulfates, chlorides, carbonates and bicarbonates of sodium, potassium, calcium and magnesium. When the salt content in the topsoil is too high or exceeds the limit of what the crop can tolerate, growth is stunted and the dangers of soil salinization are manifested. Citric acid on salinized soil can complex with metal ions on the soil surface, and can effectively reduce the ion concentration and its activity, which is an effective complexing agent. High soil salt content is manifested by high soil EC value, and the plant manifests itself by slow root growth or no rooting. High soil salinity is a difficult problem in modern agriculture.
Citric acid can clean the drip pipe, sprinkler irrigation system, is an excellent chelating agent.
Sprinkler irrigation, drip irrigation system for long-term use of the inner wall will produce a variety of precipitation, precipitation will be accumulated over time to block the drip hole, affecting the effect of fertilizer application. Citric acid can dissolve the precipitation material inside the drip irrigation wall, and play the effect of cleaning drip irrigation. Effectively prevent dripper clogging. Usually 45 days to use once, drip when the water can be matched in the water. Crops have the effect of promoting root growth and reducing soil EC value.
Citric acid has the ability to regulate soil acidity and alkalinity and activate soil trace elements.
Citric acid is an organic acid with strong buffering properties. Regular use of citric acid can keep the pH value of the soil in a weakly acidic environment, which is conducive to the absorption of trace elements, especially iron, manganese, copper and zinc, and the nutrient absorption and utilization rate of the soil is best when the pH value is 6.5-7.
Citric acid has some fungicidal properties and can inhibit the growth of soil pathogens.
Citric acid has a certain bactericidal effect and can kill some of the soil pathogens. Inhibit the propagation and growth of soil pathogens.
