Soil Management, Irrigation and Fertilisation Strategies for N2O Emissions Mitigation in Mediterranean Agricultural Systems

Feeding a growing population, which will reach 10 billion in 2050, is major challenge. Another challenge to increase crops’ productivity sustainable way, as the agricultural inputs may lead greenhouse gas emissions, including N2O fertiliser. Several factors can influence emissions such irrigation, soil management system, or type of fertiliser used. The aim this research study impact each above-mentioned factor on during three seasons maize field, considering nitrogen fertilisers: urea (U), ammonium nitrate (AN), and with nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP); two irrigation strategies: demand (100%) deficit (75% demand); comparison systems: conventional tillage (T) systems no-tillage (NT) system. interactions among their effects were analysed through principal component analysis. Higher recorded plots that received highest dose. most favourable reduce derived from activity for crops under Mediterranean climate was NT management, using an dose 75% irrigation.
