Abstract EN

This experiment was conducted in silt clay soil at fall season 2014 in the field that belongs to College of Agriculture –university of Basra/ Garmat- Ali site to study the effect of three factors in factorial experiment: First factor.

oil conditioner includes ( black petroleum .

used grease oil and bitumen) while second factor includes concentrations ( 0 .

0.1 .

0.3 .0.5 % ) which are calculated on the basis of dry weight .while the third one is emulsion factor consists of two treatments:(without emulsification of oil conditioner and with emulsification of oil one.

The emulsification of oil conditioner was done by adding fortified industrial emulsification of the kind ionic (7 mmole) from active substance per liter of used water in emulsification process .The procedure was done by using mechanical mixture with quantity of water which is enough to reach the soil moisture to saturation state .The product mixture is added to the experimental units.

The area of each basin 10m x 2m separated them by soil shoulders of 1m width by plastic pipe by using free flow irrigation.

The results showed that a significant increase the frontal water movement of horizontal wetting advance and reduction in the recession of water from the soil surface plant height and productivity by use oil conditioners and this increase was better with the rise levels of the conditioner up to (0.3%).

The black petroleum and used oil grease as conditioners .showed a superior as compared with bitumen.

In addition the emulsification process.

It has a significant impact on increasing the frontal water movement of horizontal wetting advance and reduction in the recession of water from the soil surface.

in comparison with the untreated experimental units with differences of conditioner type and application level .
