Promotion Of Production And Use Of Organic Fertilizer
Page 1 of 4
Composting is the natural process of decomposition of organic materials by microorganisms under controlled conditions. Raw organic materials such as crop residues, animal wastes, green manures, aquatic plants, industrial wastes, city wastes, food garbage etc. enhance their suitability for application to the soil as a fertilizing resource, after having undergone composting. The end product of the process is compost or humus which, is of value in agriculture. In addition, compost could be considered as a value added product of organic materials, which has a high commercial value when compared to many other forms of organic materials.
AIM OF THE PROJECT
Increase sustainable crop production, improvement of long-term soil fertility for better farmer livelihood, alleviating rural poverty and reduce foreign exchange drain on chemical fertilizer imports.
OBJECTIVES
Long-term objectives:
- Increase crop productivity.
- Improve soil fertility.
- Reduce chemical fertilizer imports.
Short-term objectives:
- Use of freely available organic materials in crop production.
- Identification and utilization of new sources of organic materials.
- Generate organic materials such as green manure, animal manure etc.
- Compost production using freely available organic waste materials such as urban waste, industrial waste, animal waste, domestic waste etc.
- Increase production of high quality organic fertilizer by introducing correct technologies.
- Increase organic fertilizer production at different levels such as large, medium and small scales.
- Quality control of organic fertilizer production through implementing SLSI standards.
- Generate more employment opportunities by promoting commercial organic fertilizer
- production.
- Increase organic fertilizer marketing system.
|
- Improvement of infrastructure facilities for commercial organic fertilizer production.
- Set-up analytical service centers in every province to analyze organic fertilizer,
- chemical fertilizer, plant, soil and water samples.
- Popularize IPNS technology.
- Improve soil fertility and conserve agricultural lands in sustainable manner.
- Increase the efficiency of chemical fertilizers by introducing IPNS technology.
- Increase crop productivity by introducing correct soil fertility management practices as well as by making adjustments to current nutrient management practices.
- Increase farmer income for better livelihood and alleviating poverty.
- Develop technology packages in relation to sustainable agriculture systems.
- Minimize environmental pollution.
