Which is Better, Water Soluble Fertilizer or Compound Fertilizer

Water Soluble Fertilizer

It is a kind of fast-acting fertilizer with good water solubility and no residue, which can be completely dissolved in water and can be directly absorbed and utilized by the root system and foliage of crops. It can be directly absorbed and utilized by the roots and foliage of crops. By using water and fertilizer together, water with fertilizer, water-fertilizer integration is realized, and its effective absorption rate is more than double that of ordinary chemical fertilizers, reaching 80~90%; and the fertilization effect is fast, which can solve the nutritional needs of high-yielding crops in the rapid growth period. With the drip irrigation system, the water requirement is only 30% of that of ordinary chemical fertilizer, and the fertilization operation can be done almost without manual labor, which greatly saves labor cost.

Compound Fertilizer

Compound fertilizers have a wide variety of nutrients, and a single application of compound fertilizer can supply at least two or more major nutrients to the crop at the same time. For example, ammonium phosphate does not contain any useless by-products, its anions and cations are the main nutrients absorbed by the crop. This fertilizer has a more uniform distribution of nutrients, and after causing granules compared to powdered or crystalline unit fertilizers, it has a tight structure, uniform nutrient release, and a stable and long fertilization effect. It has less adverse effects on the soil due to fewer by-products.

Difference One. Nutrient Composition

Water-soluble fertilizer refers to a compound fertilizer completely soluble in water, the form is mainly divided into solid and liquid, the nutrient content is divided into large amounts of elements, medium elements and trace elements water-soluble fertilizer, the market also commonly exists in the functional water-soluble fertilizer containing amino acids, humic acid, etc.. Water-soluble fertilizers not only have more types, and a variety of ratios, such as a balanced ratio of nitrogen, phosphorus and potassium balanced fertilizer, high nitrogen fertilizer, high potassium fertilizer and high phosphorus fertilizer, etc., while the fertilizer itself also contains a variety of trace elements that play a key role in the growth of different crops, while the traditional compound fertilizer, although it contains two or more elements of fertilizer, but the main component is only nitrogen, phosphorus and potassium, the formula and nutrient elements are relatively single.

Difference Two, Method Dosage

Water-soluble fertilizer is more widely used in almost all regions of China, taking the application method mainly for foliar spraying, drip irrigation under the membrane, root flushing and mountain sprinkler irrigation, etc., can be developed for different geographical characteristics of the planting environment application methods, unlike compound fertilizers must be used entirely for planting crops under the soil. Water-soluble fertilizer is usually concentrated powder or liquid, the amount used is generally less, to the ordinary balanced water-soluble fertilizer, for example, if flushing, the amount required per acre is only about 5kg, while the use of compound fertilizer is less than about 40kg.

Difference Three, the Effect

Water soluble fertilizer is mainly used as a crop fertilizer, and other traditional fertilizers such as urea, the difference is that water soluble fertilizer is a fast-acting fertilizer, the crop absorption rate is faster, but the duration of the effect after application is relatively short, only for the peak of fertilizer during crop growth, and compound fertilizer is generally used as the initial planting of fertilizer, WeChat search vegetable farmers circle concern. Water-soluble fertilizer absorption and utilization rate is high, according to experiments show that if the application method is appropriate, generally up to about 90%, up to 95% or more, almost all absorption, while the traditional compound fertilizer in the process of crop growth absorption and utilization rate of only about 60% at most.
