Abstract

A field experiment was conducted at the Agricultural Research Station in Agriculture College, University during the autumn season 2020 to study the effect of the interaction of the use of organic waste, diesel oil and four leaching requirements (0, 10, 20, 30%) with irrigation water on some properties Soil and some elements of corn plant growth using plastic columns. Soil samples with silty clay texture, depth 5-30 cm, were taken from the field of the Agricultural Research Station and after mixing, a weight of 7 kg was taken for all treatments and placed in anvils in the form of an incomplete cone containing a filter of gravel and graded sand with a soil column height of 25 cm A space of 5 cm was left empty from the top for the purpose of irrigation. Cow residues were added to the soil as an organic matter of 4% mixed with soil and diesel oil at a rate of 0.5% of the dry weight of the soil by spraying soil particles with oil solution as soil conditioners. Soil and plant measurements and yield at the end of the growing season were taken and included: the electrical conductivity of the soil, the draining water, the bulk density of the soil, the moisture content before the subsequent irrigation, as well as the plant growth indicators such as the height of the plant and the dry weight of the plant. The results showed that the use of hydrophobic oil materials such as diesel oil or organic waste in certain proportions led to an improvement in the efficiency of washing salts from the soil, especially when treating the addition of diesel oil, thus reducing the effect of salinity of irrigation water. The results also showed that the addition of leaching levels of up to 10% is sufficient to maintain the salt balance in the soil and prevent its effect on plant growth, as the level of 10% did not differ significantly from the treatment rated for rinsing of 20%. The results also showed that the use of hydrophobic oil materials according to non-toxic percentages of the plant led to the preservation of soil construction and the prevention of salinization of the soil surface as a result of its effect in reducing the capillary activity of water and this even led to a reduction in the amount of added water as the need for washing or rationed washing or the total amount of water during a season the growth.
