There are many methods for the application of trace element fertilizers, such as soil fertilization, seed treatment, and top dressing.
Soil fertilization. When applying basal fertilizer, seed fertilizer or top dressing, apply trace element fertilizer to the soil. Although this fertilizer has a low utilization rate of fertilizer, it has a certain aftereffect. This fertilization method is often used for industrial waste containing trace elements and slow-effect micronutrients.
Seed treatment. Including soaking and dressing two methods. When soaked, the seed is immersed in a trace element solution, the seed absorbs the solution and swells, and the fertilizer enters with the water. The commonly used concentration is 0.01% to 0.1% and the time is 12 to 24 hours. Seed dressing is to use a small amount of water to dissolve the trace element fertilizer, spray the solution on the seed, stir evenly, so that the seeds outside the solution stained after the dry seeding, generally with 2 to 6 grams of fertilizer per kilogram of seed.
Root dressing outside. That is, the trace element fertilizer solution is sprayed onto the plant with a sprayer, and is absorbed into the leaf surface or stomata and then transferred to the plant body. The commonly used solution concentration is 0.01% to 0.1%.
Roots. This is a special fertilization method for rice. Other crops that need to be transplanted can also be fertilized with roots.
