Soil Properties

Spatial analysis and mapping of intensity and types of agricultural salt-affected soils around Abaya and Chamo Lakes, South Ethiopia Rift Valley

“…In addition to this, additional factors may contribute to the alkalinity of the study soils since it is in the Rift Valley, a region of volcanic activity, and the volcanic ash that has fallen over the area is often alkaline. Some fertilizers, such as lime and urea, can make the soil more alkaline, and some minerals, such as sodium bicarbonate and sodium carbonate, release alkaline ions when they dissolve in water [ [79] , [80] , [81] ]. The high alkalinity of the soils around Abaya and Chamo Lakes can negatively impact agriculture.…”

How Does Irrigation with Wastewater Affect the Physical Soil Properties and the Root Growth of Sugarcane under Subsurface Drip?

“…On the other hand, irrigation provided in the shallowest layer increased soil density and soil compaction, i.e., there was an increased amount of soil mass per unit volume [71][72][73], hindering root penetration and water movement, affecting sugarcane development [74][75][76][77] and long-term water infiltration into the soil [78][79][80]. However, this negative effect was balanced by better root development in the shallower layers of the soil, ensuring efficient use of soil resources, increasing nutrient and water absorption and resulting in better crop growth and development [81][82][83].…”
