How to apply fertilizer in the critical period of crop nutrition?
2024-03-27
In the process of crop growth and development, the requirements for nitrogen, phosphorus, potassium and other mineral nutrients often have two very important periods, which are also the key period of fertilization. If the demand for nutrients can be met in time during these two periods, it will improve crop yield and quality.

How Do Crops Absorb and Use Nutrients?
2024-03-27
The root system of crops is the main organ to absorb nutrients and water, and most of the nutrients needed for their growth and development are absorbed from the soil by the root system. The nutrients absorbed by the roots are mainly various inorganic nutrient ions dissolved in the soil solution, including anions and cations. For example, the absorbed chlorine is mainly ammonium ion and nitrate ion, the absorbed phosphorus is mainly hydrogen phosphate ion, and the absorbed potassium is mainly potassium ion, etc.

The applied fertilizer can not only supply the nutrients needed by crops, but also improve the soil. For example, the application of lime to acidic soils can neutralize the acidity of the soil, reduce the toxic effects of iron and aluminum, and improve the effectiveness of soil nutrients. On the contrary, the application of gypsum and yellow repellent to the soil can chemically react with sodium and sodium bicarbonate in the soil surplus solution to generate soluble sodium sulfate, which can reduce the alkalinity of the soil in combination with irrigation and drainage measures.
