Other claims from this paper (9)
- Intervention effect Incorporating water hyacinth residues into the top 0-30 cm of soil significantly increased dry matter weight loss compared with surface application.
- Intervention effect Sub-surface application of water hyacinth had a higher decomposition rate constant (0.041% week-1) than surface application (0.029% week-1).
- Observation Potassium was the fastest nutrient released from water hyacinth residues, with 50% loss reached after the 2nd week (incorporated) and 6th week (surface).
- Intervention effect Nitrogen, P, Ca and Mg release from water hyacinth incorporated in the sub-soil was significantly higher than from surface application.
- Observation Nutrient loss from water hyacinth residues followed the order K = Mg > P > N > Ca.
- Intervention effect In the greenhouse study, incorporating water hyacinth residues significantly decreased hydraulic conductivity by 40-46%.
- Intervention effect In the greenhouse study, incorporating water hyacinth residues increased cation exchange capacity by about 23%.
- Intervention effect In the greenhouse study, incorporating water hyacinth residues increased organic C by 100%.
- Recommendation The authors conclude that water hyacinth could be a good alternative for improving the quality of arid soils.
