The main objectives of this study were to
evaluate the effect of animal manures combinations and
humic acid on some soil biochemical properties. The
laboratory incubation experiment was conducted using a
completely randomized design with three replicates. The
animal manures included chicken manure (ChM) and cow
manure (CoM). The treatments of humic acid (HA),
chicken manure (ChM) and cow manure (CoM) were
applied on clay soil at a rate of 10 t. ha-1. The treatments
used were: Control (T1), HA (T2), HA + ChM (T3) and
HA + CoM (T4). The soil samples were incubated for 15,
30, 45 and 60 days at 28 ˚C and was analyzed for soil pH,
the electrical conductivity (EC), total nitrogen, available
phosphorus, potassium content, soil organic carbon
percentages (SOC) and soil respiration (CO2). In
general, the results showed a significant difference
between all treatments and the control. Also, the
applications of treatments have lowered the soil pH and
significant increase in EC was observed as days of
incubation. While, the N, P, K, SOC and soil respiration
(CO2) were significant increased and reached its peak at
45 days of incubation and decreased thereafter with time.
The results showed that applications of organic matter
had significant effect on soil biochemical properties and
treatment 4 T4 (HA+ CoM) showed a significant
superiority compare with other treatments.
