Non-continuous flooding irrigation practices, such as alternate wetting and drying (AWD) mid-season drainage (MSD), have been implemented in rice agroecosystems to reduce water use mitigate climate change. Draining fields reduces methane (CH4) emissions, soil aeration decreases the abundance activity of methanogens. Mitigation effects during growing season widely studied. However, there is a knowledge gap regarding potential these practices might on subsequent fallow emissions. This relevant when assessing overall annual CH4 particularly systems which seasons account for significant part these. A field experiment was Ebro Delta region (Catalonia, Spain) with objective identifying AWD MSD emitted following flooded season, comparison continuously fields. Both emissions structure microbial communities were analyzed plots under assessed strategies later mesocosm across season. achieved an average 86% decrease fluxes compared continuous resulted highest leading increases cumulative (+8%), global warming (+30%) yield-scaled (+70%) flooding. Growing decreased relative both methanogens methanotrophs Reduced methanotroph lead lower consumption, resulting higher offsetting mitigation effect Under studied conditions, represented more effective strategy. These results highlight importance considering change strategies.

Struvite (MgNH4PO4·6H2O), a mineral with low water solubility that can be recovered from industrial wastewater, has the potential to used as slow-release phosphorus (P) fertilizer. However, effect of struvite on yield and P uptake efficiency different crops remains unclear. In this study, effects struvite, diammonium phosphate (DAP), mixed fertilizer consisting + DAP (MIX) biomass, uptake, soil fractions Chinese cabbage, cowpea, maize were investigated in pot experiments. The results showed compared DAP, reduced biomass cabbage by 47%, while there was no difference cowpea under application. There total concentration plants between MIX, treatment decreased 16.73% treatment. Compared MIX 45.82% 33.41%, respectively, direct cowpea. Soil Olsen-P CaCl2-P concentrations highest among treatments. significantly increased water-soluble 5.87% 5.23%, lower than addition, pH phosphatase activity DAP. This result suggested three treatments had weakest crop growth. crops, maize, compatibility highest. These provide valuable insights for future application agricultural production achieving stable yields mitigating environmental risks.
