According to the characteristics of crops and fertilizers, the spring plowing can select suitable fertilizer varieties, which can fully exert the fertilizer efficiency, reduce the production cost and obtain high yield.
Different crops apply ammonium nitrogen (such as ammonium bicarbonate, ammonium sulfate, ammonium chloride, urea) or nitrate nitrogen fertilizer (such as ammonium nitrate) to cereal crops such as corn and wheat. Potato and sweet potato should use ammonium nitrogen fertilizer. In addition, different crops have different nitrogen requirements. Leafy vegetables require more nitrogen fertilizer for the crops to be harvested, while legume crops only need to apply a small amount of nitrogen fertilizer at the early stage of growth and when the nodule has not yet functioned.
Different crops responded to phosphorus differently from legume crops (soybeans, peanuts), fiber crops, potato crops (potato, sweet potato) and melons. Phosphorus fertilizers had better effects. Both calcium and heavy calcium are water-soluble phosphate fertilizers, which are easily absorbed and utilized by crops.
Different crops have different potassium requirements for different crops containing carbohydrates (potato, sweet potato, watermelon, etc.). Nitrogen is avoided in these potassium-producing crops. If potassium chloride is applied, the yield and quality will decrease. Potassium sulphate is suitable for various soil crops, and can be used as base fertilizer, seed fertilizer, top dressing and top dressing. Potassium chloride is not suitable for seed fertilizer.
Different crops react differently to sulfur, sodium and chlorine. Potato, soybean, peanut and rape are the sulfur-loving crops, and the calcium is better than heavy calcium. Beet sodium, sodium nitrate is a good fertilizer for sugar beet. Chlorine can increase the toughness and tensile strength of fiber. Ammonium chloride is suitable for cotton, hemp and other crops.
