The study was conducted to evaluate the total carbon stocks sequestered
in a Jatropha – based alley cropping system treated with varying
fertilizer applications. The study was laid out in Randomized Complete
Block Design with three replications. The alley was planted with corn in
two seasons Treatments include control (no fertilizer), organic
fertilizer and inorganic fertilizer applied to the alley crops. Findings
showed that the treatments with fertilizer applications had higher
carbon stock in the jatropha hedges.
The carbon content of the corn
stover was also higher in organic and inorganic fertilizer-applied
treatments. However, highest soil carbon content was shown in treatments
applied with organic fertilizer (4.28 Ton ha-1). The inorganic
fertilizer treatment had the lowest soil carbon content with a mean of
4.28 Ton ha-1. In terms of total carbon stock of the entire
jatropha-based alley cropping system, there was a significant difference
among treatments with organic fertilizer application having the highest
mean of 7.79 Ton ha-1 while the inorganic treated plots had 6.53 Ton
ha-1. The no fertilizer treatment had the least carbon stocks with 6.53
Ton ha-1.
This recent study revealed that the jatropha-based alley
cropping system is a potential land-use for carbon sequestration. This
farming system needs to be promoted in upland areas to function not only
as soil and water conservation measures but also as a possible remedy
for global warming.
