Needs Address
Increased and better quality agricultural production
Adaptation effects
- Helps to conserve soil moisture, prevent soil degradation, and protect vegetables from rains and high temperatures
- Enhance soil fertility, structure and other soil properties
- Reduces water use by up to 75% as it protects the soil from evaporation
Overview and Features
Organic and inorganic materials applied over or in the soil surface
Cost
- Mulching material – no cost if organic and locally available material used
- Can offset production costs and other constraints associated with land preparation
- Manual labour
Energy source
Human labour
Ease of maintenance
Integrated into harvesting routine and therefore may require less maintenance than land preparation via burning or removing mulch material after previous harvest
Technology performance
- Prevents weed growth and supplies organic matter for heterotrophic nitrogen fixing microorganisms, which could be utilized by succeeding crops
- Good for moisture retention
Considerations
Not suitable for crops that require silty soils or are subject to collar rot in moist conditions
Co-benefit, suitability for developing countries
- Contribute to the development of sustainable integrated weed management systems and seek the possibility of minimizing herbicide use in direct seeded rice cultivation
- Straw mulch significantly increased soil organic carbon content under no-tillage and permanent beds over un mulched treatments
- Crop residue recycling increases soil organic carbon and total N contents
- A Good Agricultural Practice, addressing environmental, economic and social sustainability for on-farm processes
- Mulching with plastic film has been reported to cause extreme increase in soil temperature during the summer months in sub-tropical areas
