How to spray water soluble fertilizer scienctifically?
Water soluble fertilizer is a kind of quick effect fertilizer, if with good water soluble ability and no residue, that can dissolve in water completely.It can be directly absorbed by the roots and leaves of crops.
Nowadays, with the shortage of water resources, the application of water-soluble fertilizer has become one of the important measures for increasing agricultural efficiency and farmers’ income. So, what skills should be mastered and what should be paid attention to when applying water-soluble fertilizers?
1. Avoid direct impact
Take secondary dilution water soluble fertilizer is higher than general compound fertilizer nutrient content, consumption is relatively small, directly applied can be easily burn seedlings root , the phenomenon such as weak seedling rootstocks, secondary dilution is not only conducive to fertilizer applied evenly, it can also improve the fertilizer utilization ratio.
2. Apply a small amount by several times
Water-soluble fertilizers are quick and effective, and are difficult to be retained in soil for long time. Therefore, the most important principle is a small amount applied by multiple times.In line with the characteristics of continuous nutrient absorption in plant roots, the leaching loss caused by a large amount of fertilization can be reduced.
3. Pay attention to nutrient balance
Generally, we use irrigation, spraying and drip irrigation.Due to the dense growth and large quantity of crop roots, the dependence on soil nutrient supply is reduced and more dependent on nutrients provided by drip irrigation.If the water-soluble fertilizer formula is not balanced, it will affect the growth of crops.
4. Apply kinds of fertilizer together
Water – soluble fertilizer is fast – efficient fertilizer, general speaking,it can only be used as track fertilizer,
especially in conventional agricultural production, water-soluble fertilizers cannot replace other conventional fertilizers. In order to reduce the cost and give full play to the advantages of various fertilizers, it is necessary to combine base fertilizer with fertilizer, organic fertilizer with inorganic fertilizer, water soluble fertilizer with conventional fertilizer.
5. Avoid excessive irrigation
With fertilization as the main purpose of irrigation, the depth of the root layer just be moist.
Excessive irrigation not only wastes water, but also drains nutrients below the root layer, leaving crops unable to absorb it and waste fertilizer. Especially, urea and nitrogenous fertilizer in water soluble fertilizer are easily lost with water.
