Greenhouse gas emissions associated with four types of fertilization for corn crops in a Mediterranean basin

The environmental impacts associated with the intensification of agricultural practices have become an emerging issue, and new techniques are being developed to satisfy public demands. application fertilizers is a crucial step for agriculture practices. Building upon previous studies at Mediterranean basin, objective research presented herein was quantify greenhouse gas emissions four different types fertilization in production corn: traditional (NPK 8–15-15 urea), controlled-release 8–15-15, combination urea encapsulated two pig slurry amounts urea). Life Cycle Assessment methodology employed, Ecoinvent database IPCC 2013 GWP 100y impact assessment method. results revealed that emitted 3251 kg CO2-eq/ha·year, against 2191 CO2-eq/ha·year fertilization. Pig 2160 its alternative less urea, only 1030 CO2-eq/ha·year. utilization solves issue disposal entails lower costs (commercial fertilizer prices follow oil gas). demonstrated potential contribute climate change mitigation.
