Summary
This study evaluated biodegradable mulch materials, like plastic and paper, to reduce agricultural waste. Image analysis determined mulch residue, showing potential for environmental pollution reduction.
Area of Science:
- Agricultural Science
- Environmental Science
- Soil Science
Background:
- Mulching improves agricultural soil conditions, commonly using black polyethylene (PE).
- Disposal of PE mulch and its soil residues pose environmental challenges.
- Biodegradable plastics (BD) and paper (PP) offer sustainable alternatives to reduce waste and pollution.
Purpose of the Study:
- To evaluate the residue of various mulch materials in agricultural soil.
- To assess the degradation potential of biodegradable mulches.
- To compare the effectiveness of different mulch types in a Central Spain crop campaign using image analysis.
Main Methods:
- Color images of mulched experimental fields were captured under consistent lighting.
- Image analysis techniques, including histogram saturation plane thresholding, were employed.
- The percentage of bare soil (white pixels) was calculated to quantify mulch deterioration.
Main Results:
- Different thresholding methods were compared for optimal soil-mulch contrast.
- The percentage of bare soil area varied among the tested mulch materials.
- Image analysis provided a quantitative measure of mulch residue and degradation.
Conclusions:
- Image analysis is a viable method for assessing mulch residue and degradation.
- Biodegradable mulches show potential as sustainable alternatives to conventional PE mulch.
- Further research can optimize biodegradable mulch selection for reduced environmental impact.
