Although water soluble fertilizer has a lot of advantages, but many growers in the use of the time because of the use of incorrect and can not play its fertilizer effect, and even produce fertilizer damage. So today let's talk about the correct use of water soluble fertilizer:

1. avoid direct application

Many growers think that since water-soluble fertilizer is soluble in water, it is only necessary to apply it directly, but this view is incorrect. The direct application of water-soluble fertilizer may cause uneven concentration of water-soluble fertilizer solution, resulting in weak seedlings in places with low concentration and burning seedlings in places with high concentration.

Therefore, the correct way to use water-soluble fertilizer is to dilute it twice, which can not only ensure the uniformity of the fertilizer, but also give full play to the maximum fertilizer effect of the fertilizer.

2. control the amount of fertilizer, a small amount of multiple applications

The biggest characteristic of water soluble fertilizer is that the nutrient composition is relatively high, that is to say, the fertilizer efficiency is relatively large, and the fertilizer efficiency is fast, it is easy to be absorbed by crops, the water soluble fertilizer dissolves fast, the absorption and utilization rate is high, and the crops are easy to absorb. When applying fertilizer, the amount of water soluble fertilizer should be controlled, and a small amount of more fertilizer should be applied. Under normal circumstances, 3~5Kg.

3. attention to nutrient balance

Water soluble fertilizer is generally applied by pouring, spraying, or mixing it into water, along with irrigation (drip irrigation, sprinkler irrigation) application. It should be reminded that when using drip irrigation fertilization, due to the intensive and large amount of crop root growth, 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 unbalanced, it will affect crop growth.

In addition, water soluble fertilizer should not be applied with traditional irrigation methods such as flood irrigation or water irrigation to avoid fertilizer waste and uneven application.

4. application

Water soluble fertilizer for quick-acting fertilizer, generally only as top dressing. Especially in regular agricultural production, water soluble fertilizer can not replace other regular fertilizers. It is necessary to combine base fertilizer with top dressing, organic fertilizer with inorganic fertilizer, and water-soluble fertilizer with regular fertilizer, so as to reduce costs and give full play to the advantages of various fertilizers.

5. as far as possible to use alone or mixed with non-alkaline pesticides

When vegetable deficiency occurs, many growers use imported water-soluble fertilizers, which can effectively alleviate vegetable deficiency and promote vegetable growth. The public number of chemical fertilizer price information hereby reminds that water-soluble fertilizer should be applied alone or mixed with non-alkaline pesticides as far as possible to avoid precipitation due to reaction of metal ions, resulting in leaf fertilization or pesticide damage.

6. avoid excessive irrigation

When the main purpose of irrigation is to fertilize, the root layer depth can be wet. The depth of the root layer of different crops varies greatly. You can use a shovel to dig up the soil at any time to understand the specific depth of the root layer. Excessive irrigation not only wastes water, but also causes nutrients to be leached below the root layer, which can not be absorbed by crops and wastes fertilizer.

In particular, urea and nitrate fertilizers (such as potassium nitrate, calcium ammonium nitrate, nitro phosphate fertilizer and water-soluble fertilizer containing nitrate nitrogen) in water-soluble fertilizers are easily lost with water.

7. to prevent surface salt accumulation

Long-term use of drip irrigation and fertilization in greenhouses or greenhouses will cause surface salt accumulation and affect root growth. Drip irrigation under mulch can be used to inhibit salt migration to the surface.

In addition to multi-element compound fertilizers, there are also some bio-organic fertilizers, water-soluble fertilizers, and bio-bacterial fertilizers, water-soluble fertilizers. When using these fertilizers, we must pay attention to the use methods in order to better exert the fertilizer effect.
