“…1a, c), and the addition of litter to microcosms significantly enhanced the emission of soil CO 2 and N 2 O. Similar results were found in other ecosystems (Huang et al 2004;Mungai and Motavalli 2006;Jiang et al 2013;Begum et al 2014). The enhanced emissions may be due to the supply of energy during litter decomposition, which can stimulate significantly microbial activity (Ma et al 2013).…”

“…However, a double pool model with four parameters was able to describe the decomposition pattern of all residues more accurately (Fig. 3, solid lines) indicating the presence of different labile and recalcitrant carbon fractions among residues, which is in conformity with similar observations by Urquiaga et al (1998) and Mungai and Motavalli (2006). The decomposition rate, k 1 , was higher than k 2 .…”

The objectives of this study were to investigate decomposition patterns and soil organic matter (SOM) accumulation of incorporated residues (10 Mg ha -1 year -1 ) of different quality, and identify microbiological parameters sensitive to changes in SOM dynamics, in a 13-year-old field experiment on a sandy soil in Northeast Thailand. Mass loss was fastest in groundnut stover (high N), followed by rice straw (high cellulose) and tamarind (intermediate quality), and slowest in dipterocarp (high lignin and polyphenol) following a double exponential pattern. The decomposition rate k 1 (fast pool) was positively correlated with cellulose (r = 0.70*) while k 2 (slow pool) was negatively related to lignin (r = -0.85***) and polyphenol (r = -0.81

“…Residue decomposition rates and nutrient release or mineralisation patterns are controlled by both biotic and abiotic factors, the most important of which is residue quality (Vanlauwe et al, 1996;Silver and Miya, 2001;Mungai and Motavalli, 2006;Teklay et al, 2007). In order to manage the N mineralised from organic residues for crop uptake, there is need to understand decomposition and N mineralization patterns of the organic inputs in relation to their chemical composition.…”

Biomass transfer or cultivation of leguminous trees has higher eco-friendly profiles for soil nutrients restoration especially nitrogen. The research is conducted on decomposition and nitrogen release patterns of Parkia biglobosa and Albizia lebbeck leaves with nitrogen fertilizer for maize production in sudan savannah alfisol of Nigeria. Data were analysed using (ANOVA). 56 % of N in the litter bag was released the first two weeks of biomass incubation and progressively increases weeks after planting. Decomposition rate constant (KD) ranged from 9.18 to 15.07 week -1 and the rates of plant residues was higher in Albizia lebbeck than Parkia biglobosa in both seasons. Nitrogen release rate constant (KN), ranging from 7.82 to 10.81 week -1 followed a similar pattern as the rate of decomposition with Albizia lebbeck releasing the highest amount of N followed by Parkia lebbeck. The rate of decomposition increased as week increased. Incorporation of Albizia lebbeck had significantly higher effect (p < 0.05) on growth parameter and yield component compared to Parkia biglobosa. The study concluded that Albizia lebbeck decomposed and mineralized faster for crop uptake under sudan savanna conditions. The study suggests that incorporation of Albizia lebbeck and up to 40 kg N ha -1 is a better combination for soil quality improvement and maize productivity in Makera, a semi-arid environment of Nigeria.
