Currently, farmers are standing in the matrix matrix of organic fertilizer with hundreds, thousands of brand names, uses, components, … different. So people need to know and understand the organic fertilizers to make intelligent choices, select quality fertilizer products, suitable for cultivating crops to achieve fruitful results. High in agricultural cultivation.
I. What is Organic Fertilizer?
Fertilizers containing micronutrients, micronutrients, in the form of organic compounds, used in agricultural production, derived from feces, animal waste, Handles, residues, leaves, byproducts from agriculture, peat or organic matter from household waste, kitchen, seafood factories … when fertilizing soil Organic fertilizers help improve soil fertility, increase soil fertility by providing nutrients, humus, microorganisms to soil and plants.
Classification of organic fertilizer
Organic fertilizers are classified into two main groups:
Traditional organic fertilizers such as manure, green manure, compost, etc.
Organic industrial fertilizers such as bio-organic fertilizers, organic fertilizers, microbial organic fertilizers, microbial fertilizers and mineral fertilizers.
1. Traditional organic fertilizers
Livestock, by-products of agricultural production, agro-forestry-fishery processing, garbage, green manure, etc. are processed by traditional brewing techniques. Traditional organic fertilizers generally have a slower effect, longer processing time and low nutrient content.
Manure is derived from faeces, animal urine (poultry manure, cattle, feces). Prepared by traditional composting techniques and methods.
Manure consists of macro, medium and micronutrient nutrients supplied to the plant, provides humus for soil improvement, increases fertility, softens soil and stabilizes the soil structure, Development, limited erosion, drought.
Low nutrient content in large volume, high transportation cost, labor intensive.
Without thorough processing or use of fresh manure, it will carry many pathogens to plants such as fungal spores, bacteria, viruses, weed seeds, insect-feeding pupae … or intestinal eggs, Influence on human health.
Manure is derived from manure and urine
Green manure is commonly referred to as fresh plants or leaves processed by composting or buried in soil to fertilize crops and soil.
Green manure has the effect of protecting, improving land, reducing erosion.
When green manure is buried on the soil, organic decomposition (decomposition of green manure) occurs, which often results in toxic substances such as CH4, H2S, etc., which cause organic toxins. Green manure has a slow action and is only useful for lining.

These are the traditional methods of composting from straw, stems, leaves from agricultural production.
Garbage manure improves porosity, stabilizes soil texture, limits soil erosion and drought tolerance.
Garbage has low nutrient content, processing is complex and takes a long time. And can carry disease germs or weed seeds available in the source material (residues of crops for composting).
Straw to compost waste
Peat does not directly fertilize but must be processed for use in plants.
Peat is good for fertilizer application, increasing soil fertility as well as organic soil.
Low nutrient content, complex processing should be applied in large amounts both costly and costly.
2. Organic fertilizer processing according to industrial processes
Organic fertilizers are made from a variety of organically derived organic compounds in industrial processes up to thousands of tons, applying scientific and technological advances to produce fertilizers. Fertilizer is better quality, full of nutrients compared to raw materials and traditional organic fertilizers.
Organic fertilizers are produced by industrial processes
Fertilizer is a component of one or more useful microorganisms, including: organic microorganisms, nitrogen fixation microorganisms, parasitic microorganisms, microorganisms Resistance, microbial degradation of cellulose, …
Supplementation promotes the development of soil micro-organisms, solubilizing difficult-to-absorb plant species into plant-readily absorbed forms, synthesizing a number of nutrients for plant major crops such as N, Control pathogens that exist in the soil, improve the efficiency of the use of fertilizer.
Fertilizers do not provide or only provide a moderate amount of nutrients (from nitrogen fixation microorganisms, phosphorus-decomposing microorganisms, etc.) to crops that are insufficient to supply. Enough and balanced nutrients for plants.
There is a shelf life and each type is highly dependent on crop groups. For example, fertilizer nitrogen fertilizer is suitable only for legumes, ….
Microorganisms must have organic matter as a food source to grow the fertilizer and supplement the fertilizer to feed the livestock, thus raising the cost of organic fertilizer.
Is a fertilizer product made from organic materials mixed and fermented by the presence of one or more beneficial microorganisms to increase and balance the nutrient content needed. Set for the plant. There are over 22% organic ingredients.
It is possible to fertilize all stages of the crop: basalting, applying, fertilizing, …
To provide adequate and balanced mineral nutrients necessary for growing plants, healthy development, increasing productivity and quality of agricultural products.
Add a large amount of humus, Humic acid, Humin, …. It improves the chemical — biological — physical properties of the soil, limits the washout of nutrients and soil erosion, and decomposes toxins in the soil.
Supplement promotes the development of microorganisms that help to control pathogens in the soil, provide natural antibiotics to increase the natural resistance and resistance of plants to pests and diseases. Benefit from weather, limited pests.
Increases the absorption of nutrients from the soil by providing microorganisms that are difficult to absorb (difficult to digest), easy to digest, easy to digest, easy to digest. People and creatures are useful.
Organic bio-fertilizers are usually expensive compared to other fertilizers, but the cost is not a problem, as a return on higher costs but with better quality will increase productivity and quality. The amount of agricultural products, thereby improving economic efficiency and income. In addition, it will minimize or eliminate the use of chemical fertilizers and pesticides, thereby reducing the cost of chemical fertilizers and pesticides to ensure human health.
C. Organic micro-fertilizer
The product is processed by industrial process from various sources of organic material, fermented with one or more beneficial microorganisms, containing live spores. Contains organic content of more than 15%.
Provide enough mineral nutrients, medium, micronutrients for plants, improve soil fertility, porosity. Provides microorganisms that disintegrate difficult-to-absorb substances into readily absorbed, antimicrobial, parasitic, … soils that inhibit the growth of pathogens in soil, Plant resistance, no pollution of the environment, no toxic to humans and useful organisms.
Normally the content of organic matter is less than the organic fertilizer.
D. Organic mineral fertilizers
Organic fertilizers and mineral fertilizers, including N, P, K. Contains less than 15% organic ingredients, 8–18% total inorganic (chemical, N + P + K).
High levels of mineral nutrients.
Long-term fertilization is not good for soil and soil microflora.
Which organic fertilizer selection is best and most effective? At present, there are some high-level bio-organic fertilizers such as OBI-Ong Biển organic fertilizer, which is a breakthrough product in the agricultural sector. Necessary nutrients for crops, increased productivity and quality of agricultural products, the provision of organic materials to improve soil fertility, increase soil fertility, improve soil water retention and reduce erosion. Bio-organic fertilizers OBI-Ong Biển Sea Bion also added the antimicrobial species to help prevent pests and diseases, microorganisms decompose organic substances … thereby increasing economic efficiency, reducing the cost of stools. Fertilizers and pesticides, consumer health using agricultural products are guaranteed.
