| description | Understanding the influence of agricultural soil management practices on soil
processes and the environment is vital for sustainable food production. Therefore, this study
evaluated the impact of soil temperature and moisture on soil organic carbon mineralisation
under synthetic (NPK) and organic (biochar) amendments in a maize cropping system in
Ilorin, Southern Guinea Savanna of Nigeria. The objectives were to determine the C
mineralisation and C sequestering potential under each amendment and assess how
precipitation amounts and soil temperature influence carbon mineralisation. Two soil types
(Anthrodensic Ustorthent and Typic Ustorthent) were used, and four treatments (control,
NPK, biochar+NPK, and biochar) replicated thrice were laid out in completely randomised
design on each soil. Soil respiration was measured in-situ by the alkali absorption method.
Data collected was subjected to analysis of variance procedure for complete randomized
design to determine significant differences in treatment means, correlation and regression
analyses were also carried out to test the relationships amongst experimental factors and
variable responses. Results showed that evaluated nutrient management options did not
significantly influence C mineralisation. C mineralisation, however, differed between soils,
with Typic Ustorthent having higher organic carbon (OC), total CO2 emission (82.35 mg) and
mean CO2 emission rates (1.18 mg m -2 d -1 ). Correlation analysis showed differing
relationships between soil temperature and C mineralisation under the different treatments
and soils, with significant positive correlation (r=0.44; p= ≤ 0.05) recorded only under sole
biochar treatment in the Typic Ustorthent. Rainfall amounts had no significant correlation
with C mineralisation |
