Effect of Tillage Depth on Some Properties of Saline Soil

Abstract

A field experiment was conducted to quantify the effect of tillage depth and irrigation application rates on total porosity, saturated hydraulic conductivity, EC and pH of Al-Hussainiya saline clay soil. Wheat crop (Triticum aestivum; misr-1) was cultivated. Soil physical and chemical properties were measured before and after wheat cultivation. The irrigation water was, also, chemically analyzed. The soil properties were measured at three tillage depths and four irrigation application rates. The obtained results showed a reduction in both EC and pH and increase in both total porosity and hydraulic conductivity with increasing tillage depth. Therefore, the study recommended a deep tillage and water application not less than field capacity to improve soil properties and increase soil hydraulic conductivity and, hence, enhance leaching salts in the clay saline soil, especially, from the surface layers.

Integrated Effect of Mole Drains Systems and Planting Methods on Saline Soil Chemical Properties and Wheat Productivity

“…The presented data in Table (2) show that, soil pH in all experimental plots were slightly alkaline, where its ranged between 8.70 in zero tillage treatment in basins planting method (M0) to 8.14 with tillage treatment of 2 m distance and 40 cm depth under furrows planting method (M2). Generally, with the treatments of drainage system and planting methods, soil pH was decreased compared with the initial soil pH (Table 1) which resulted from the improve effect of farming processes such as organic manure application on soil chemical properties (Abou Hussien et al, 2020;Abou Hussien et al, 2022). The highest significant decrease in soil pH appeared with M2 (8.17) treatment, while the lowest one was in M0 (8.70).…”
