Abstract:
Soil samples were collected from three locations different in their textures,
namely ; clay ,silty loam and sandy loam to study the effects of three levels of
both polymers (0.0, 0.25 and 0.5% ) and animal manures (0.0 , 2 and 4 %) .
Results of laboratory study indicated that moisture content of soils increased
with animal manures compared with the control , especially with increasing
measuring time for the silty loam soil compare with the clay soil .Results of the
saturated, field capacity and the lower moisture content reveals significant
differences for the animal manures and the second level of polymer as
compared with control ,where the silty loam soil gave 3.09 , 6.5 and 7%
respectively .On other hand ,the field experiment with animal manures gave
significant differences for plant height and clear effect in plant dry weight as
compared with control .
