Benefits of processing organic fertilizer with fertilizer by bio fertilizer granulator

fertilizer granulator Jan 4, 2023

At present, the actual utilization rate of chemical fertilizer in China is only 30% – 45%, even lower in some regions! After the application of organic fertilizer, the beneficial biological activity improves the soil structure, increases the soil water and fertilizer conservation capacity, thus reducing nutrient loss, and increasing the effective utilization rate of chemical fertilizer to more than 50%. It can also reduce the amount of chemical fertilizer and the cost of fertilization. Since the 1970s and 1980s, the UK, France and Japan have reduced the use of pesticides and fertilizers. Organic fertilizer is the main fertilizer. The use of chemical fertilizers and pesticides has been greatly reduced. The grain output has increased and the quality is much better than before. Therefore, the fertilization method of “giving priority to organic fertilizer, supplemented by chemical fertilizer” is a reasonable fertilization method at present!

Five benefits of the combination of organic fertilizer and chemical fertilizer produced by biological fertilizer granulator! Benefit 1: The fertilizer has high nutrient content and fast fertilizer effect, but its duration is short and the nutrient is single. Organic fertilizer is just the opposite. The mixed use of organic fertilizer and chemical fertilizer can complement each other and meet the nutrient demand of crops in each growth period.

Benefit 2: After chemical fertilizer is applied to the soil, some nutrients are absorbed or fixed by the soil, reducing the availability of nutrients. After mixed application with farmyard manure, it can reduce the contact surface between fertilizer and soil, reduce the possibility of fertilizer being fixed by soil, and improve the availability of nutrients.

Benefit 3: Generally speaking, the solubility of chemical fertilizer is large, which will produce high osmotic pressure on the soil after application, affect the absorption of nutrients and water by crops, and increase the chances of nutrient loss. If it is mixed with organic fertilizer, it can avoid the disadvantage that crops absorb nutrients and water.

Benefit 4: If acid fertilizer is only applied to alkaline soil, after ammonium is absorbed by plants, the remaining acid root will combine with hydrogen ions in the soil to produce acid, which will lead to acid enhancement and soil hardening. If mixed with organic fertilizer, it can enhance the buffer capacity of the soil, effectively regulate the pH and prevent the increase of soil acidity.

Benefit 5: Since organic fertilizer is the energy source of microbial life, chemical fertilizer is the inorganic nutrition for microbial growth and development. The two mix the vitality of microorganisms to further decompose organic fertilizers. The activity of soil microorganisms can also produce vitamins, biotin, niacin, etc. Increase soil nutrients, improve soil vitality and crop growth.

How much profit can be gained from processing fertilizer with sheep manure organic fertilizer production line

fertilizer granulator Jan 4, 2023

Organic fertilizer can improve the utilization rate of fertilizer in the soil. The main raw material of organic fertilizer is animal manure. They include: pig, cow, chicken, sheep, etc. There are many advantages in using sheep manure to produce organic fertilizer.

Raw material analysis of sheep manure organic fertilizer

Nutrition analysis: 24% – 27% organic matter content, 0.7% nitrogen content to 0.8%, 0.45% to 0.6% and 0.3% potassium content to 0.6%, organic matter sheep urine 5% content, 1.3% to 1.4% phosphorus content, nitrogen content is extremely low, very rich in potassium, as high as 2.1% to 2.3%

Character analysis: Sheep are ruminants, but they rarely drink water, so the stool is dry and thin, and the stool volume is very small. Sheep manure is a kind of thermal fertilizer between horse manure and cow manure.

Sheep excreta and urine are rich in nutrients, which can not only easily decompose the effective nutrients absorbed by crops, but also have the late nutrients that are not easy to decompose. It is a good fertilizer that combines the efficiency and speed of fertilization. The decomposed sheep manure treated by the compost turning machine is suitable for the application of various soils.

Technology of sheep manure organic fertilizer production line

Sheep manure was composted and fermented by high-temperature fermentation bacteria, straw was crushed, and the materials were mixed with biological compound bacteria, and the compost turner was used for regular composting. The decomposed organic matter can be directly made into powder fertilizer or further processed. Sheep manure compost as a part of raw materials, mixed with inorganic fertilizer according to the formula, can be called high efficiency organic fertilizer after NPK production line processing.

Special reminder: all animal manure must be put into the ground through harmless fermented fertilizer before use. Because the raw fertilizer contains a variety of harmful bacteria, it will breed diseases and insect pests, damage soil health, thus affecting the healthy growth of crops.

In short, organic fertilizer is a kind of green and harmless soil fertilizer, and it is the mainstream of future agricultural development. It is recommended that we do not use chemical fertilizers in a single organic fertilizer for the best results.
