Clear Paper on Resource Utilization of Livestock and Poultry Manure in Bayannur, Inner Mongolia

Dear breeding farm (household) friends:

With the continuous expansion of livestock and poultry breeding scale, manure treatment has become a key issue restricting industrial development. Many people see manure as a burden, but in fact, it is a misplaced resource. Promoting the resource utilization of livestock and poultry manure is not only a mandatory requirement of laws and regulations, but also a "golden key" to reducing breeding costs, improving soil fertility, and achieving green income growth. In order to help everyone turn "waste" into "treasure", this comprehension paper will explain in detail for you.

1、 Recognize the situation:

Why should we carry out resource utilization?

The previous practice of 'pushing manure out, no matter where it flows' is no longer feasible.

1. The red line of environmental protection cannot be touched: Direct discharge of manure can lead to black and odorous rivers, groundwater pollution, and foul air. It not only damages the environment, but also faces severe penalties from ecological and environmental departments, including fines, production restrictions, and even production shutdowns.

2. Waste of resources is unacceptable: Livestock and poultry manure contains a large amount of nitrogen, phosphorus, potassium, and organic matter, making it a high-quality source of agricultural fertilizers. Directly discarding is equivalent to throwing away the 'money', while purchasing fertilizer costs a lot of money.

3. The combination of planting and breeding is the direction: returning manure to the field can increase soil organic matter, improve soil compaction, and enhance the quality of agricultural products, which is the only way for the sustainable development of modern agriculture.

2、 Key technology: How to turn manure into treasure?

Based on the scale of aquaculture, manure removal methods, and surrounding land conditions, the following mainstream utilization modes are recommended:

1. Total collection and utilization mode of manure returning to the field

Target audience: Small and medium-sized farmers with sufficient farmland, vegetable fields, or orchards in the surrounding area.

Construction facilities: Construct a manure storage tank with functions of "rain proof, anti-seepage, and overflow prevention".

Harmless treatment: The manure in the pool needs to be sealed and fermented for at least 30-45 days. Remember: It is strictly prohibited to directly use "raw manure" that has not been decomposed, as the secondary fermentation of raw manure in the soil can produce high-temperature seedlings and carry a large number of insect eggs and bacteria.

Scientific returning to the field: During the fertilization season, fermented manure is evenly applied to farmland through tanker trucks or pipelines.

2. Solid liquid separation+comprehensive utilization mode

Target audience: Large scale breeding farms with a high degree of automation.

Source control: Adopting dry cleaning technology to reduce the amount of sewage generated from the source.

Solid liquid separation: Separate manure into solid and liquid parts through a solid-liquid separator.

Solid utilization: The solid part has low moisture content. By adding straw and microbial agents for composting and fermentation, it can be used to produce commercial Organic Fertilizers or for personal use. It is suitable for economic crops such as fruit trees, tea, and vegetables.

Liquid utilization: The liquid portion enters the black film biogas digester or anaerobic fermentation tank, and the generated biogas can be used for power generation or domestic fuel; The fermented biogas slurry is stored in an oxidation pond and ultimately used as liquid fertilizer for field application.

3. Ectopic fermentation bed mode

Target audience: Water scarce areas or farms without sufficient farmland to absorb liquids.

Operation process: Construct a fermentation tank outside the breeding house, fill it with sawdust, straw and other bedding materials, evenly spray the manure into the bedding materials, and regularly flip the piles through a flipping machine. Utilize microbial aerobic fermentation to decompose the manure, and finally produce decomposed organic fertilizer.

3、 Standardized management: Remember daily operations

In order to ensure the true implementation and effectiveness of the resource utilization of livestock and poultry manure, daily management must be solid and meticulous.

First, the facilities should operate normally. Sewage treatment facilities such as dung dump, sewage pool and solid-liquid separator should operate normally all day long and should not be left idle or damaged at will. Especially, patrol and reinforce in advance before rainstorm to prevent environmental pollution caused by sewage overflow.

Secondly, the ledger records must be detailed, and a standardized "Livestock and Poultry Manure Resource Utilization Ledger" must be established. This is the key basis for environmental inspections, and it is necessary to record in detail the daily or monthly amount of manure generated, the treatment methods used (such as composting, fermentation, etc.), and the destination of manure utilization, that is, the specific village, household, and land where it is transported, the crops it is applied to, and the amount applied; If third-party transportation is entrusted, the transportation agreement and handover records must be properly retained.

Thirdly, a disposal agreement must be signed. For farmers whose breeding scale does not match their own land, they must sign a "Fecal Waste Disposal Agreement" with nearby planting cooperatives, family farms, or farmers in advance to ensure a stable field outlet for manure in the form of a contract, truly realizing the integration of planting and breeding and circular utilization.

4、 Avoiding Misconceptions: These Practices Must Not Be Used

Misconception 1: As long as it is not discharged, it can be stored outdoors.

Correct answer: Outdoor stacking can cause fecal matter to cross flow when it rains, which still constitutes environmental pollution. There must be a ceiling, a fence, and a hardened floor.

Misconception 2: The biogas slurry in the digester can be directly discharged into the river.

Correct answer: Although the biogas slurry has undergone fermentation, it is still a high concentration fertilizer water, and direct discharge into the water body will inevitably lead to eutrophication of the water. Biogas slurry must be diluted and reused for irrigation.

3. Misconception 3: With vast land and abundant resources, it's okay to apply more manure.

Correct answer: Scientific fertilization emphasizes "moderation". Excessive application of manure can exceed the absorption capacity of soil and crops, and excess nutrients can also be lost with rainwater, causing non-point source pollution.

The resource utilization of livestock and poultry manure is beneficial to the country, the people, and oneself. Let's take action and follow the path of "planting and breeding combined, circular development", protect the green mountains and rivers of our hometown, and exchange them for long-lasting gold and silver mountains!
