Abstract
This work was carried out to study the effect of OLBA additions in improving
physical properties of sandy and calcareous soils. Surface Soil samples were
" collected for research purpose from Ismalia and Nubaria regions, respectively.
Soil conditioner was added at rates of 0.0, 0.1, 0.2 and 0.5% and thoroughly
mixed with the investigated soil portions. Then the soil were subjected to wetting and
drying cycles for five weeks, whereas the lower soil moisture content, were in the
range of 3-5%, while the upper values were in the range of 9-15%.
The results revealed that the tested conditioner improved soil properties as
well as its ratio increased. Total porosity, available water and aggregates percentage
were increased, while bulk density values were decreased in both soils. The hydraulic
conductivity values were decreased in the sandy soil. While its values slightly
increased in calcareous soil, due to re-distribution of soil pores.
Finally, application of OLBA had improved physical properties of the tested
soils, consequently it is suitable for conditioning soils. OLBA efficiency was 10% from
agrosoke efficiency, for the same rate of addition on similar soils.
