Mitigating N2O emissions from agriculture: A review of the current knowledge on soil system modelling, environmental factors and management practices influencing emissions

The AgriGES project is a Concerted Research Action lead by Gembloux Agro-Bio Tech, aiming to quantify methane and nitrous oxide emission from pastures and crop fields, respectively. Besides quantification, a second important goal of the AgriGES project is to study the flux dynamics and to gain a better understanding of the biophysical processes coming into play. We focus here on N2O fluxes and first propose an overview...

Influence of cassava peels and poultry manure-based compost on soil properties, growth and yield of waterleaf (Talinum triangulare Jacq) in an ultisol of south-eastern Nigeria

Effects of cassava peels and poultry manure based compost and their sole applications on soil properties, growth and yield of waterleaf were investigated at the University of Calabar Teaching and Research Farm during 2013 and 2014 cropping seasons.  The experiment was laid out in a randomized complete block design (RCBD) with three replications.  There were seven treatments consisting of mixture of cassava...

Variation in nutrient concentrations of basement complex and sedimentary rock of teak plantations in Ogun State, Southwest Nigeria

This study examined the differences in the nutrient concentration of the parent material of teak plantations under basement and sedimentary rocks in south western Nigeria. Systematic line transect was employed to establish 18 plots (30 m x 30 m), each in Ilaro (sedimentary rock) and Olokemeji (basement complex rock) plantations which were 37, 40 and 42 years old while twelve rock samples each from 3 quadrants each of 30...
