A research project was conducted to evaluate the impact of alternative citrus nitrogen and water management practices on groundwater nitrate concentrations beneath the vulnerable sandy soils in the ridge citrus region of Central Florida. Fifteen months of baseline data indicated that groundwater nitrate-nitrogen concentrations were above the Environmental Protection Agency’s Maximum Contaminant...

The partial substitution of chemical nitrogen fertilizers with organic fertilizer and slow-release could improve pineapple yield use efficiency (NUE) decrease greenhouse gas (GHG) emissions. However, the effect strategies on carbon footprint (CF), (NF) net ecosystem economic benefits (NEEB) from fields in tropics remains largely unclear. Therefore, we conducted a long-term field trial (2017–202...

Pig farming produces more manure than can reasonably be spread onto surrounding fields, particularly in regions with high livestock densities and limited land availability. Nutrient recycling offers an attractive solution for dealing with manure excesses and is one main objective of the European commission-funded project “BioEcoSIM”. Phosphate salts (“P-Salt”) were recovered from the separated ...
