Mixed mineral fertilizer: The fertilizer is produced by mixing mechanical two or three types of single mineral fertilizer or mixing with complex fertilizer, not using chemical reactions.

Mixed feces: As a fertilizer in the composition containing two different nutritional elements (inorganic, organic, microorganisms, other nutritional factors) or more, including types of organic fertilizer processing industrial, biological fertilizer, mineral fertilizer, microbiological fertilizer.

Organic industrial processing mechanism: is a fertilizer manufactured from organic materials, processed according to the process of industrial fermentation technology, with organic matter content, symbolized by HC (in HC -number) and quality criteria meet the regulations of national technical regulations.
Biological fertilizer: A fertilizer produced from organic materials, fermented with useful microorganisms or processed by other biological agents with quality criteria that meet the regulations according to national technical regulations.
Organic mineral fertilizer: is a fertilizer manufactured from an industrial or biological mechanism of organic or organic mixing, one or some of the inorganic nutritional factors, including at least one multi -volume inorganic nutritional factor meets the provisions of the national technical regulation.
Microbiological fertilizer: A fertilizer produced from organic materials containing at least one useful living microorganisms with density and activity that meets prescribed in accordance with national technical regulations.

Microbiological fertilizer: As a fertilizer in the composition contains one or more useful microorganisms including a group of nitrogen -fixed microorganisms, phosphorus resolution, cellulose resolution, antagonistic microorganisms, microorganisms that increase photosynthesis and other useful microorganisms with density and activity prescribed in accordance with national technical standards.

Classification by function

Foliar fertilizer: are fertilizers suitable for direct spraying into the stems, leaves and suitable for plants to absorb nutrients through the stems and leaves.
Root fertilizer: are fertilizers that are fertilized directly into the soil or water to provide nutrients for plants through the roots.

Fertilizers are commonly used today

On the current fertilizer market, the ingredients as well as the names of fertilizers are very diverse. Blog Kiến Thức Tổng Hợp Nông Nghệp will provide some of the following fertilizers.

Magnetic inorganic fertilizer

Nitrogenous

Is the common name of inorganic fertilizers used to provide nitrogen for plants. Fertilizer will promote the growth of the tree, causing the tree to produce many branches, branches, leaves and leaves with large size, green, strong photosynthesis leaves thus increasing crop productivity.

Nitrogenous

Phosphate

Plays an important role in crop life. Stimulating the growth of the roots, causing the roots to spread deep, so the trees are less falling, stimulating the tillering process, budding. Promote the tree to flower early and more, increase the properties of anti -cold, anti -drought, resistance, anti -pests.

Phosphate

Potassium

Provide nutrients K for plants. Increasing the ability to withstand drought, drought, cold and resistant to pests, giving the tree firm, less falling, increasing agricultural productivity.
Potassium chloride: In the form of pink or opaque gray powder, gray white, crystallized into small seeds, containing 50-60% pure k pure and some salt. This is a type of physiological and sour, easy -to -fertilized, easy -to -fertilized or fertilized fertilizer, suitable for many lands except for saline soil.
Potassium sulfate feces: Small crystal, smooth, white, easy to soluble in water, less lumpy. Contains 45-50% p. But suitable for many crops.
Some other types of potassium fertilizer: Potassium – Magnesium sulphate is used effectively on poor sand soil, faded soil; Canada’s Agripac fertilizer is dry, large, non -clumping, containing 61% K2O, often used to mix with other fertilizers; 40% potassium salt has a crystalline white salt with some light pink scales, containing 40% k, limited use on saline soil.

Potassium

Complex fertilizer and mixed fertilizer

There are the following types on the market: Type 2 elements (NP, NK, PK), type 3 elements (NPK), type 4 elements (NPK-MG).

Inorganic fertilizer and micronutrients

Median fertilizer: Normally, factories do not produce separate median fertilizers but combine with multi -quantities. There are several types of median fertilizers: sulfur, calcium fertilizer, magnesium fertilizer.
Micronutrients: Including boromes, isomers, manganese fertilizer, molipden fertilizer, zinc fertilizer, iron fertilizer, cobalt fertilizer.

Fertilizer fertilizer

Are nutritious compounds, which can be macro, medium or micronutrients, which are dissolved in water and sprayed on the tree for plants to absorb.
Leaf fertilizers can be single fertilizers such as N, P, K, Cu, Zn, … However, most of the fertilizers through leaves are mixture of multi -trace and micronutrients in the form of water soluble in water.

Organic fertilizer
