Organic fertilizer production for industrial processing
Soil organic matter is considered as a criterion for assessing soil fertility. So any soil with a higher organic matter content will be better evaluated.
For example, 2 soil types have nearly the same origin, but the analysis shows that 1 soil type has an organic matter content of 1.05% and 1 soil type has an organic matter content of 5.3%. , without considering other agrochemical or physical criteria, it can be immediately thought that soils with 5.3% organic matter content will have better fertility.
Why do you say that? Because soil with a high organic matter content will first of all have better physical properties, the soil becomes loose, porous, and the soil grain is not fragmented or too compacted.
If the soil is fertile, the soil contains a lot of air, microorganisms are active, earthworms are also active, making the soil more and more porous.
Soil has a better ability to hold moisture, so it can avoid drought better. Organic matter has good buffering ability, so it keeps the pH of the soil less changed, better able to keep the minerals applied by us to provide better roots gradually.
Therefore, scientists advise that it is necessary to fertilize the soil or at least re-fertilize a portion of the organic matter taken away by the plant each crop.
In production, there are many types of organic fertilizers, temporarily classified into the following groups:
–Traditional organic fertilizersThis includes livestock and poultry manure such as buffalo, cow, pig, chicken, duck, goat and sheep waste. Types of this waste if pure use it has quite high nutritional content. For example, in fresh cow manure contains protein about 0.341%, buffalo manure contains 0.306% and pig manure contains 0.669% N.
But in manure, due to the need to have a lot of manure, fillers are often added such as straw, garbage, leaves, grass … The nutrient content of manure is more or less depending on the amount of added fillers, but surely Definitely much less than pure manure.
In addition to the above fertilizers, we also have pond sludge, sugar mill sludge, green manure, and other types of waste.
–Organic fertilizers for industrial processing, include:
Organic fertilizers: Having an organic content of about 20%, containing protein 2% or more, a C / N ratio of about 12 (organic matter to protein).
Organic mineral fertilizers: Having an organic content must be 15% or more and the total N + P + K must be 8% or more (8 – 18%).
Bio-organic fertilizers: Content of Humic, Fulvic or Humin acids or total amino acids, vitamins or other biological compounds must be 5% or more.
Microbiological organic fertilizer: Organic matter over 15%, at least 1 useful microorganism with a cell density of at least 1.5 x 106 / gr or ml.
Organic mineral fertilizers: There are organic substances accounting for 5 – 15%, minerals about 18% or more.
Microbiological fertilizers: In feces contains at least 1 strains of useful microorganisms, has a minimum number of living spores 1.5 x 108.
Applying organic fertilizers of all kinds to crops is generally very good. But if we want to know whether organic fertilizers ensure enough nutrition for plants, we first need to know that every plant needs at least 16 essential nutrients, which are N, P, K Ca, Mg, S , Si and trace elements.
These substances are present in organic fertilizers. But the content is very different.
Meanwhile, to have 3 tons of dried black pepper, plants taken from the soil and fertilizers are about 400 kg N, 220 kg P and 350 kg K. So we need to know that these fertilizers contain bags. The amount of minerals and how much content is enough to calculate correctly for the plant.
So if we only fertilize the plant with organic fertilizers of all kinds, we need to provide enough quantity to have enough essential minerals, then we will still have high yield. And the longer the organic manure, the better the soil properties, not the poorer.
