Soils and soil management

Land suitability and surface water resources potential for irrigation in Becho Plain, upper Awash basin, Ethiopia*

“…This is consistent with the textural nature of the soil in the central part of the study area which is dominantly fine-textured clayey soil. Clay soils demand provision of proper drainage systems and management for better functioning and aeration in agricultural practice (Lal & Shukla, 2004;Finch, Samuel, & Lane, 2014).…”

Introductory Chapter: Soil Erosion at a Glance

“…This characterization is made on the basis of the physical properties of soil, alone, regardless any exogenous factors like land cover, land use, or support practices. Studies on the physical properties of soil have shown that soil texture (sand, silt, clay content) and organic matter play an important role to soil erodibility [19][20][21][22][23]. According to Wischmeier and Mannering [24], a soil's inherent erodibility is a complex property dependent both on its infiltration capacity and its capacity to resist detachment by rainfall and transport by runoff.…”

“…Wischmeier and Mannering [24] report that a soil type becomes less erodible with decrease in silt fraction, regardless of whether the corresponding increase is in the sand fraction or the clay fraction. Generally, silty and sandy soils with low content in clay and organic matter are known to be more prone to erosion [23][24][25]. For a better comprehension of soils' texture, FAO's World Reference Base for Soil Resources [26] provides particle classes, according to their size ( Table 1).…”

Agricultural Land Dryness Distribution Using the Normalized Difference Drought Index (NDDI) Algorithm on Landsat 8 Imagery in Eromoko, Indonesia

“…Eromoko is located in the Wonosari geological formation. It has a limestone parent rock (Bronto et al, 2009) with limestone parent material that has soil problems in water availability (Finch et al, 2014) because of a shortage of water in the root layer soil due to the water movement into the soil (Maulana, 2019).…”
