Rare earth micro-fertilizers can promote crop growth, and mastering the key application points is crucial
Rare earth micro-fertilizers are a type of micro-fertilizer whose main active ingredients are rare earth elements. Agricultural rare earths are mostly made from nitrates or chlorides of light rare earth elements such as lanthanum and cerium, with a relatively low content of active ingredients. They belong to the category of auxiliary fertilizers and can regulate the physiological activities of crops, but they cannot replace macro-element fertilizers such as nitrogen, phosphorus and potassium.
Rational application of rare earth micro-fertilizers has a certain promoting effect on seed germination, root growth and leaf photosynthesis, and can also help crops absorb nutrients from the soil more effectively. In production, they are commonly used on crops such as grain, vegetables and fruit trees, mostly sprayed at key stages such as the seedling stage and flowering stage, playing an auxiliary role in improving quality and efficiency together with conventional fertilization.
Common application methods include foliar spraying, seed soaking, seed dressing and soil application, and the usage differs for different crops and different growth stages. When foliar spraying, dilute to the appropriate concentration according to the product instructions, choose a windless sunny morning or evening, try to spray the fertilizer solution onto the underside of the leaves, and avoid high-temperature periods to prevent leaf burn.
When using them, adhere to the principle of using a small amount and an appropriate amount; too high a concentration may instead inhibit crop growth. Rare earth micro-fertilizers generally should not be mixed directly with alkaline fertilizers or alkaline pesticides, to avoid precipitation and reduced fertilizer efficiency. Products should be stored in a cool, dry place and used up as soon as possible after opening. Before large-scale application, a small-area trial can be conducted first, and after observing the crop response, it can be gradually extended.
