What are the benefits of manure? Why is it necessary to compost before fertilizing?

Manure is manure produced by livestock and poultry, by-products in agricultural production, forestry and aquaculture processing, waste and green manure. It provides an excellent source of nutrients for plants while also adding nutrients.

For planting land

Strengthen and improve soil structure

Organic matter in manure contributes to improved soil structure, leading to improved water infiltration and greater water retention leading to reduced plant stress, soil erosion and increased nutrient retention

Create a favorable environment for microorganisms to grow

Synthetic fertilizers are composed of carbon-free chemical molecules. These molecules can sometimes be disruptive and inaccessible to bacteria. On the other hand, organic fertilizer is rich in organic matter that helps microorganisms thrive.
Manure contains most of the elements necessary for plant growth including N, P, potassium and trace elements (Manure as a source of plant nutrients and soil improvement). However, it is the organic carbon of manure that provides its potential environmental value. Organic carbon from manure provides an energy source for the microbial environment in the soil to function well, both stabilizing the nutrient source and providing nutrients for plants.
Create sustainable, environmentally friendly agriculture
Synthetic fertilizer runoff into our waterways harms marine life and water quality. Compost does not wash off easily (if at all) and is related to the structure of the soil. According to the Organic Trade Association, organic fertilizers also increase species biodiversity by 30% compared to synthetic fertilizers.
Reduce the amount of chemical fertilizers and pesticides
Although organic fertilizer may be more expensive than synthetic fertilizer, it can reduce the need for pesticides and the overall need for nitrogen, phosphorus and potassium. Due to the reduction, organic fertilizers can be cost-effective and sometimes even cost-effective.

• For plants
• 
  Provides essential macro, secondary and micro mineral nutrients for plants
  Helps plants grow healthy and green: Manure helps plants grow healthily. Especially supporting healthy green leaves and limiting leaf loss.
  Supports the strong growth of plant roots, increases the activity of microorganisms in the root zone, and increases the efficiency of chemical fertilizer use.

Why must manure be composted before use?

Manure is a traditional organic fertilizer with high nutritional value, very useful for plants. But it is only truly good for soil and plants when it has been carefully treated to remove all harmful risks. Because fresh, untreated manure still has many disadvantages such as:

• 
  Foul odor: Fresh manure often has a foul odor that affects the environment.
  Contains many grass seeds and larvae:

Fresh manure contains many weed seeds, larvae, spores of fungi, bacteria, nematodes, etc. that cause diseases in plants. The composting process generates heat which will help destroy some harmful microorganisms and weed seeds in fresh manure. It also promotes the decomposition of organic matter. Accelerates the mineralization process when applied to soil, quickly providing nutrients to plants.

• 
  Reduce pH:

Fresh manure, when applied directly to the soil, will continue the decomposition process to create a lot of organic acids. These organic acids gradually accumulate over time, leading to a decrease in soil pH, affecting growth and development. of plants.

Competition for nutrients:

Fresh manure contains a high C/N ratio. When applying fresh manure directly, microorganisms that decompose organic matter will need a lot of nutrients and will compete with plants for nutrients.

Killing plants:

Some fresh manure contains a large amount of nitrogen and mineral salts. When applied directly to plants, it will cause heat to affect the roots, and if too much can cause the plant to die.

Contains minerals that are difficult to digest:

Fresh manure contains indigestible mineral compounds that are difficult for plants to absorb. Therefore, composting fresh manure takes advantage of the temperature and added microorganisms in the compost pile to quickly convert indigestible substances into easily absorbable substances.
