| Abstract | ||
| The study was carrid out in Apel Area-Homs by using the waste water from phosphatic fertilizers industry, after mixing it with fresh water, in three levels (75%, 50% and 25%). Samples of soils took from these depths 0-15, 15- 30 and 30-60 cm before planting and after harvest, and samples of water from well and waste water (before and after mixing it, in three levels 75%, 50% and 25%). The aim of this paper was to study the influence of irrigation with waste water from phosphoric fertilizers industry on some soil characteristic and the production of maize. The data showed negative relationship between the level of mixing with waste water of Kalnitro fertilizers and soil's pH. The use of waste water of Kalnitro fertilizers decreased external density of soil from 1.4 gm/cm3 to 1.11 gm/cm3. The irrigation with waste water of Kalnitro fertilizers increased the concentrations of TDS in soil, but relationship between the level of mixing with waste water of Kalnitro fertilizers and carbonate and active lime was highly positive. The level of mixing with waste water of Kalnitro fertilizers 25% gave high production of maize (4.48 t/ha) but irrigation with waste water of Kalnitro fertilizers without mixing gave low production of Maize (1.21 t/ha). | ||
