The difference between water-soluble fertilizer and chemical fertilizer

Different definitions: water-soluble fertilizer refers to the compound fertilizer containing nitrogen, phosphorus, potassium and other elements that can be completely dissolved in water, and chemical fertilizer refers to fertilizers containing one or several nutrients made by chemical and physical methods.

Different ingredients: water-soluble fertilizers contain large amounts of elements (nitrogen, phosphorus, potassium), trace elements (manganese, zinc, copper, etc.), the traditional chemical fertilizers have a single component.

Fertilizing methods are different: water-soluble fertilizers can be drip irrigation, flushing, foliar spraying, traditional fertilizers are usually dug into the pit.

First, the definition of different

1, water-soluble fertilizer

is able to completely dissolve in water containing nitrogen, phosphorus, potassium, amino acids, humic acid and other composite fertilizers, generally solid, liquid or powder, can be applied as a fertilizer.

2, fertilizer

refers to the chemical and physical methods made of fertilizers containing 1 or several kinds of nutrients needed for crop growth, common urea, diammonium, composite fertilizers, and water-soluble fertilizers with a large number of elements, usually in granular form, can be used as a base and follow-up fertilizer.

Second, the composition of the different

1, water-soluble fertilizer

(1) large elements: contains nitrogen, phosphorus, potassium, most of which are soluble in water.

(2) Trace elements: contains molybdenum, boron, calcium, iron, manganese, zinc, copper, magnesium and other elements, the use of multi-chelate technology production and processing, which can improve crop nutrient absorption.

(3) Other ingredients: mainly including humic acid, amino acids, active bacteria. Humic acid can regulate the problem of soil sloughing and acidification, and improve the soil environment; amino acid can promote the overall absorption of nutrients; and active bacteria can enhance the crop's resistance to soil diseases.

2, chemical fertilizer

Traditional fertilizers have a single component, containing only part of the nitrogen, phosphorus and potassium elements, and poor water solubility, long-term use of the soil is likely to cause agglomeration, fertility decline.

Third, the fertilization method is different

1, water-soluble fertilizer

According to the instructions for use of water dilution, and then flush, foliar spraying, or direct drip irrigation, the operation is simple, without the need to dig a pit mulch.

2, chemical fertilizers

Generally have to dig pits to apply fertilizers, fertilizers should be mulched, more labor, and inconvenient to transport, storage.
