High Quality Low Cost China 6-7T/H Poultry Manure Sludge Straw Organic Fertilizer Project Report

The total investment of the 6-7t/h poultry manure sludge straw organic fertilizer factory project is 7.52 million yuan, the total land area is 7,500m2, and the total construction area is 4325m2. The 6-7t/h poultry manure sludge straw organic fertilizer factory project adopts the mixed compost fermentation process to produce solid organic fertilizer.

The production capacity is 20,000 t/a of solid organic fertilizer. The current actual production of solid organic fertilizer is 7000t/a. The main raw materials required for the 6-7t/h poultry manure sludge straw organic fertilizer factory project are livestock manure, domestic sewage treatment plant sludge, plant straw, cakes, etc.

The 6-7t/h organic fertilizer producion line project products mainly produce farmland fertilizers, tobacco leaf fertilizers and garden fertilizers according to actual orders. The sludge from the domestic sewage treatment plant is only used for the production of garden fertilizers, not as raw materials for the production of farmland fertilizers and tobacco leaf fertilizers.

The sludge is provided by Hongmiao Sewage Treatment Plant in Enshi City, and the rest of the raw materials are purchased locally; the 6-7t/h poultry manure sludge straw organic fertilizer factory use organic fertilizer pelletizer adopts extrusion granulation, no heating, and no boiler.

• Annual output: 20000 tons
• Starting construction time: March 2019
• Commissioning time: May 2019
• The actual total investment: 7.52 million yuan (1167104 USD)
• Environmental protection investment: 572,000 yuan (88774.4 USD)

The 6-7t/h organic fertilizer production project mixes raw materials such as livestock and poultry manure, domestic sewage treatment plant sludge, plant straw, and cakes to ferment to produce organic fertilizer. Among them, the sludge from the domestic sewage treatment plant is only used for the production of garden fertilizers.

The water used in the 6-7t/h organic fertilizer manufacturing project is mainly domestic water, the domestic water consumption is 0.9t/d, 270t/a, and the domestic sewage generation is 0.7t/d, 210t/a. The domestic sewage is treated in the septic tank and used for fertilization in the surrounding farmland and forests, and is not discharged.

In the 6-7t/h new build organic fertilizer factory actual construction process, in order to make better use of the site, the original layout of the two raw material warehouses was merged into one, which was set on the west side of the organic fertilizer factory project, and the rest remained unchanged.

Environmental impact changes after the layout adjustment: the organic fertilizer factory project's malodorous gas is mainly generated in the compost fermentation workshop. The organic fertilizer pellet factory project fermentation workshop has not changed, and the distance from the nearest residents is about 80m. Therefore, the impact of the 6-7 ton per hour complete organic fertilizer production factory project layout adjustment on the surrounding residents remains unchanged.

In order to promote the vigorous growth of plants, nutrients are provided by organic or inorganic fertilizers or sometimes a combination of two materials. Plants absorb nutrients from the soil, and it is not known whether it comes from organic fertilizers or inorganic fertilizers. It is recommended to conduct a soil test to determine the nutrient requirements in the soil. Soil testing helps determine which nutrients and quantities are needed.

Soil nutrients vary depending on the soil conditions, the type of plants previously planted, and the fertilizers previously used. There is a common misunderstanding that organic fertilizers are safer and more environmentally friendly than inorganic fertilizers. Improper use of organic fertilizers may also cause pollution of the soil surface and groundwater. Organic and inorganic fertilizers, if used properly, are safe for plants and the environment.

Different types of organic fertilizers release different NPK ratios in the soil, such as cow manure (2.5:1:1.5), blood meal (12:1.5:0.5), bone meal (4:20:0), earthworm compost (2 :1) :1), poultry manure (3.5:1.5:1.5), etc. According to the types of crops to be planted, organic fertilizers need to be applied appropriately; even if any organic fertilizers can be used.

Inorganic fertilizers have a high salt content; over time, the soil becomes acidic, which burns plants and keeps beneficial earthworms away. In a period of time, inorganic fertilizers will reduce soil quality, while organic fertilizer pellets will maintain soil quality.

Organic fertilizer poultry manure pellets promotes soil life by providing organic matter for microorganisms in the soil. Organic matter releases nutrients into the soil at a natural rate without over-concentrating any elements. It provides balanced nutrition and does not contain harmful residues. Inorganic fertilizer is effective in one or two weeks, but the lifespan is shorter. Chemical fertilizers cannot improve soil fertility, but may reduce soil fertility.

Due to the accumulation of salt and the loss of chemical substances, regular use of inorganic fertilizers for a period of time may cause soil and environmental pollution problems.

Organic fertilizer poultry manure pellets contains natural chemical elements, which help plants thrive. They can improve the fertility and water retention capacity of the soil, and replace the nutrients previously obtained by crops from the soil. Organic fertilizer poultry manure pellets contains macronutrients and micronutrients, the content of which varies with the material produced.

1. Nitrogen (N): It helps the growth of leaves and branches and makes them green. Excessive presence of this nutrient will make the plant fast, soft and juicy. A lack of nitrogen in the soil can make plants stunted and pale.
2. Phosphorus (P): Contributes to the overall growth of the plant, including the roots. Plant growth is hindered in phosphorus-deficient soil.
3. Potassium (K): This chemical nutrient helps protect plants from pests and diseases. Plants grown in soil with sufficient potassium will have high-quality flowers and fruits. Insufficiency in the soil will produce small flowers and fruits. The leaves turn yellow or brown.
4. Magnesium (Mg): For plants grown in soil with insufficient magnesium, the leaves will turn yellow from the veins. It helps the growth of leaves.
5. Calcium (CA): Helps protein development.
6. Sulfur (S): Helps the formation of chlorophyll and plant protein. Micronutrients:
7. Iron (Fe): The smallest amount needed for plant growth, and it is found in almost all soils. The chalky soil lacks iron, the leaves of the plants are pale and the edges are long.
8. Copper (Cu) and Zinc (Zn): These nutrients help activate enzymes.
9. Manganese (Mn): Plants grown in soil with sufficient manganese content contribute to the production of chlorophyll and protein. Insufficient manganese content will hinder growth and new leaves will turn yellow.
10. Boron (B): This is an important nutrient that helps tissue growth. "Corks" in fruits and vegetables are observed in plants grown in insufficient soil.
11. Molybdenum (Mb): helps produce protein in plants.
12. Carbon (C), Hydrogen (H) and Oxygen (O): Plants get these nutrients from air, sunlight and water.
