Four methods of application of trace element fertilizers

There are many methods for the application of trace element fertilizers, such as soil fertilization, seed treatment, and top dressing.

When fertilizing the soil, the basic fertilizer, seed fertilizer or top dressing is used to 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 includes soaking and dressing. 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 usual concentration is 0.01%-0.1% and the time is 12-24 hours. The seed dressing is to dissolve the trace element fertilizer with a small amount of water, spray the solution onto the seed, stir it evenly, so that the seed is soaked with the solution after the outside, dry seeding, usually 2-6 grams of fertilizer per kilogram of seed.

The top dressing fertilizer is to spray the trace element fertilizer solution onto the plants with a sprayer, and it is absorbed into the leaves or stomata and run into the plants. The commonly used solution concentration is 0.01%-0.1%.

This is a special fertilization method for rice. Other crops that need to be transplanted can also be fertilized with roots.
