How many common fertilization mistakes are there? What counts as unreasonable fertilization? What should you pay attention to when fertilizing? The following is a brief introduction from Gengzhongbang Planting Network, for our readers' reference.1. Shallow or surface fertilization: fertilizer volatilizes easily, is lost, or struggles to reach the crop roots, which is not conducive to crop uptake and results in low fertilizer use efficiency. Fertilizer should be applied 16-26 cm to the side and below the seed or plant.
2. Applying too much chloride fertilizer to leafy (stem) vegetables: compound fertilizer produced from ammonium chloride and potassium chloride is called double-chloride fertilizer, contains about 30% chlorine, easily burns seedlings, and requires timely watering. Chloride-containing fertilizer must not be applied on saline-alkali land or to chlorine-sensitive crops. Applying too much potassium chloride and the like to leafy (stem) vegetables not only makes the vegetables less tender and more fibrous, but also makes them taste bitter, with poor mouthfeel and low returns. Urea-based compound fertilizer is high in nitrogen, and biuret is also somewhat high in nitrogen, so it easily burns seedlings; pay attention to watering and application depth.
3. Application method: improper application methods can cause fertilizer damage, with phenomena such as burned seedlings and wilting plants. For example, applying too much chemical fertilizer at once or insufficient soil moisture after fertilization will make the soil solution concentration too high, making it difficult for crop roots to absorb water, leading to plant wilting and even death. In addition, when there is too much ammonium nitrogen in the soil, plants absorb excessive ammonia, causing ammonia poisoning.
4. Excessive use of a certain nutrient element: this will not only poison the crop, but also hinder the crop's uptake of nutrient elements, causing deficiency symptoms. For example, excessive nitrogen application causes calcium deficiency; too much nitrate nitrogen causes molybdenum deficiency and chlorosis; too much potassium reduces the availability of calcium, magnesium and boron; too much phosphorus reduces the availability of calcium, zinc and boron.
5. Applying fresh human and animal manure directly to vegetables: undecomposed livestock and poultry manure, during the decomposition process, produces large amounts of harmful gases such as hydrogen sulfide, which easily suffocates vegetable seeds from lack of oxygen; it also generates a large amount of heat, which easily burns the seeds or causes root rot, and is not conducive to vegetable seed germination and growth.
