What are the disadvantages of fertilizer guns?
If the concentration of fertilizer is too high, the fertilizer gun is easy to cause plant root burning and root water loss, and the concentration of soil solution is seriously higher than that of cell sap in plant root cells, and the water in the cell sap flows to the soil. As a result, the plant withered or even died due to lack of water. However, if used properly, not only will this not happen, but also have the following benefits.
