How To Use Water Soluble Fertilizer

- Jun 05, 2019-

With the increase in planting years, the fertility of the land is getting lower and lower, most people will choose to use fertilizer, and water soluble fertilizer is a common one. So how to use water soluble fertilizer? This article will introduce you to the use of water soluble fertilizer tips and precautions.


First, fertilizers and facilities are appropriate

Drip irrigation can be achieved without a pipe. Although the water-soluble fertilizer is marked with “completely dissolved and no residue”, there are still some substances that are insoluble in water. Pay attention to the content of insoluble matter when connecting the pipeline. Generally, the drip irrigation requirement is less than 0.2%, the micro-irrigation is less than 5%, and the sprinkler irrigation is less than 15%. Generally, the lower the water insoluble content, the better the fertilizer efficiency and the higher the price.

Second, avoid direct application

The concentration of water-soluble fertilizer is very high. If it is not used well, it will easily cause burnt seedlings. The second dilution will reduce the amount of water-soluble fertilizer, and it will not affect the effect, and indirectly improve the utilization efficiency of fertilizer. Generally, about 3 per acre. About 6 kg can be.


Third, grasp the details of fertilization

When fertilizing and fertilizing, first drip the water, and then start the fertilization after the pipeline is filled with water. In theory, the slower and more uniform the fertilization, the better the effect, and the longer the fertilization time can effectively improve the utilization rate of fertilizer efficiency; immediately after the end of fertilization, the water is poured for 20-30 minutes to drain the residual fertilizer liquid; the quick-acting effect of water-soluble fertilizer Strong, difficult to retain in the soil for a long time, so need to apply less times, reduce the leaching loss caused by one-time large-scale fertilization, and only need to make the root layer deep moist when fertilizing, do not need to fill, so as not to cause waste.

Fourth, pay attention to nutrient balance

When the water-soluble fertilizer is applied to the soil, it reaches the root system directly. If the fertilizer formula is not balanced, it will affect the growth of the crop. Because water-soluble fertilizer is a quick-acting fertilizer and cannot function for a long time, it needs the cooperation of other fertilizers to play the role of various fertilizers while reducing costs.


Fifty, Try to use it alone or in combination with non-alkaline pesticides.

Water-soluble fertilizers are generally acidic, so do not mix them with alkaline fertilizers when using them, so as not to cause fertilizer waste, and water-soluble fertilizers are dissolved in water. Try not to mix other fertilizers as much as possible to avoid phytotoxicity.

Sixth, to prevent the accumulation of salt on the surface

If the facilities such as drip irrigation and sprinkler irrigation are used for a long time in the greenhouse, the water-soluble fertilizer may accumulate the salt on the surface and affect the growth of the root system. If the drip irrigation under the membrane is used, the salt can be inhibited from migrating to the surface.
