Description Not Available
Litterfall production, decomposition and nutrient release was investigated
for three prominent agroforestry tree species, Prosopis cineraria, Tecomella
undulata and Hardwickia binata, grown in the arid western region of India.
The highest litterfall was recorded for H. binata (9.44 Mg ha−l y−1) followed
by P. cineraria (8.94 Mg ha−l y−1) and T. undulata (3.74 Mg ha−l y−1). It took
15, 12 and 9 months for decomposition of 90% of the litter of H. binata, P.
cineraria and T. undulata, respectively. Regression analysis showed that
rainfall and air temperature had significant impacts on the decomposition
process. Soil moisture and soil microbial biomass carbon showed high
correlations (R2 > 0.70, p < 0.01) with litter decay. The rate of release of
N (kN = 0.0014, surface (0–15 cm); kN = 0.0015, sub-surface (15–30 cm)) and
K (kK = 0.0041, surface; kK = 0.0047, sub-surface) was highest from P.
cineraria, whereas release rates of P were statistically equivalent for all
species. N release from the decomposing litter increased initially, but then
decreased as decomposition progressed. Concentrations of P, K and Mg in
the litter decreased throughout the decomposition, with some fluctuations
in P and Mg for P. cineraria and H. binata at the later stage. Ca release
did not follow any specific trend. P. cineraria, with considerable amounts
of litterfall, the highest nutrient inputs to the soil and the most rapid
release of nutrients during the decomposition, was concluded to facilitate
greater fertility build-up of the soil compared with the other two species.
