Nutrient Interactions
Apr 11, 2016

What is nutrient interactions? His relationship with what is fertilization? Effect of crop root system from soil solution by ion. Interactions of these ion effects on the root absorption of nutrients is extremely complex and major ion ' antagonism and synergy. 

⑴ antagonism of antagonism between the so-called ion refers to the existence of a certain nutrient ions in the soil solution, can inhibit the plant to another or the absorption of nutrients, ions. This are bad for plants to absorb nutrients. Examples of this on the production a lot, for example, nitrogen in acid soil should not be too much, or crops absorb calcium ion concentration is high, crops absorb calcium problems in potassium deficiency on the sandy soil of nitrogen combined application of potassium, potash and not excessive, because potassium ions of calcium and magnesium and ammonium uptake could have antagonistic effects. Potassium fertilizer, plants caused by lack of calcium, and magnesium. In addition, the nitrate ion antagonism with phosphate ions exist in production. Therefore, when the effect of nitrate-nitrogen fertilizer, fertilizer should be attached. When crop phosphorus deficiency due to zinc deficiency induced by excessive application of nitrogen fertilizer and crops are also typical examples of antagonism. 

⑵ synergy so-called ion synergy refers to the existence of a certain nutrient ions, can promote root on ion uptake of other nutrients. This is beneficial to the crop nutrient absorption. Anion absorption of oxygen ions generally have synergies, such as combined application of nitrogen and potassium are one example. This is because the transport of phosphorus can promote carbohydrate and amino acid synthesis, amino acid to protein synthesis. All in all, understand the interactions between nutrients and be applied in agricultural production through fertilization measures, full use of the synergies between the ion and avoid antagonism, we can achieve the objective of increasing.
