Abstract :
The study was conducted from mid-May 2022
to June 2022 during the rainy season on the
experimental plot of the University Jean Lorougnon
Guédé of Daloa (Côte d'Ivoire). The objective was to
provide good scientific information on the morphology
and the level of physical fertility of the school-field soil
for a good agricultural activity. In the field school area,
after having determined the azimuthal direction and
identified the dominant vegetation, soil pits (100 x 80 x
120 cm) were opened according to the toposequence, at
the preferential positions of plateau, slope, mid-slope and
lowland, then observed and described. After the soil
profiles were described, soil samples were taken from the
horizons (surface A and underlying B) at each level of
the toposequence to determine the physical parameters.
An analysis of variance of the data was performed with
SAS 9.4 software and the means were separated using
the Newman-Keuls test at the 5% probability level. The
results showed that at the morpho pedological level, the
field-school soil had a thick superficial A horizon (22 to
32 cm) and a deep underlying B horizon (98 to 88 cm)
from the plateau to the lowlands. A plinthitic ferralsol, a
plinthitc leptosol, a pseudogleyic ferralsol and a fluviosol
were respectively determined along the toposequence. At
the physical level, a good particle size fraction was
recorded giving a silty-sandy texture of the field-school
soil. The average bulk density (1.35 to 1.50 g/cm3) as well
as the useful reserve (>100mm) were satisfactory for
good soil water circulation. In terms of cultivation
suitability, the field-school soil did not present any major
constraints to farming. In conclusion, the champ-école
soil presented morpho pedological characteristics and
physical properties favorable to a good agricultural
activity. However, it was noted that the downstream soils
(mid-slope and lowland) would be more favorable to
food and vegetable crops while the upstream soils
(plateau and slope) would be suitable for perennial
crops.
