Water-soluble fertilizers double their effectiveness in this way

Water-soluble fertilizer has obvious advantages in improving fertilizer utilization rate, saving agricultural water, reducing ecological environmental pollution, improving crop quality and reducing labor force.Today, we bring you the key points of water-soluble fertilizer application:

1. Avoid direct flushing

Secondary dilution water-soluble fertilizer should be adopted to have a higher nutrient content than general compound fertilizer with a relatively small amount. Direct irrigation can easily cause burning seedlings and damaging roots and weak seedlings. Secondary dilution is not only conducive to uniform fertilizer application, but also can improve fertilizer utilization rate.

2. Apply a small amount more than once

Because water-soluble fertilizer is quick and effective, it is difficult to remain in the soil for a long term. A small amount of repeated fertilization is the most important principle of fertilization, which conforms to the characteristics of uninterrupted absorption of nutrients by plant roots and reduces the leaching loss caused by one-time large-scale fertilization.Generally each mu dosage in 3 ~ 6 kg.

3. Pay attention to nutrient balance

Water-soluble fertilizer is generally applied by pouring, spraying, or mixing it into water, along with irrigation (drip irrigation, sprinkling irrigation).It should be reminded that, when applying drip irrigation and fertilization, due to the dense growth and large amount of crop roots, the dependence on soil nutrient supply is reduced and more dependent on the nutrients provided by drip irrigation.If the water-soluble fertilizer formula is not balanced, it will affect the growth of crops.In addition, water-soluble fertilizer should not be applied with traditional irrigation methods such as flood irrigation or running water irrigation to avoid waste of fertilizer and uneven application.

4, with the application

Water - soluble fertilizers are quick - acting fertilizers and can only be used as top - dressing fertilizers.Especially in the conventional agricultural production, water-soluble fertilizers cannot replace other conventional fertilizers.We should combine base fertilizer with top fertilizer, organic fertilizer with inorganic fertilizer, water-soluble fertilizer with conventional fertilizer, so as to reduce costs and give full play to the advantages of various fertilizers.

5, try to use alone or mixed with non-alkaline pesticides

When vegetable appears be short of element disease or root system grows bad, many farmer use spray to apply the method of water dissolves fertilizer to try to alleviate more.Remind here, water dissolves fertilizer to want to apply alone as far as possible or mix with the pesticide of blame alkalinity, lest metal ion reacts to produce precipitation, cause leaf fertilizer to harm or medicine to harm.

6. Avoid excessive irrigation

When the main purpose of irrigation is fertilization, the root layer depth can be reached.The depth of root layer varies greatly from crop to crop.Excessive irrigation not only wastes water, but also makes nutrients leached below the root layer, which cannot be absorbed by crops and wastes fertilizers.Especially, urea and nitrogenous fertilizer (such as potassium nitrate, calcium ammonium nitrate, nitrophosphate fertilizer and water-soluble fertilizer containing nitrogenous nitrogen) in water-soluble fertilizer are easily lost with water.

7. Prevent surface salt accumulation

Long-term application of drip irrigation and fertilization in greenhouses or greenhouses will cause salt accumulation on the surface and affect root growth.Submembrane drip irrigation can be used to inhibit salt migration to the surface.
