The roots of the absorption of citrus fruit trees are mostly concentrated in the horizontal depth of about 20-40 cm below the top soil. Therefore, the shallow ditches to be fertilized are 15 cm deep from the topsoil, which will not affect the plants. And, even after cutting off a small portion of the root, it is easy to grow new roots. In addition, the soil after fertilization can reduce nitrogen volatilization, and the closer the fertilizer is to the location where the roots are absorbed, the better the plants can absorb nutrients. As to whether or not the roots will be burned when the fertilizer is applied, the main reason for this is to see how much fertilizer is used and whether the organic fertilizer is fully decomposed. If the amount of fertilizer is too much, it is too concentrated in one place, or the high temperature produced by rot in the soil after the application of the decomposed organic fertilizer is applied, of course, will damage the root system.
