“…Hence, vertisols with relatively high smectite clays have the capacity to swell significantly when moist as well as to shrink and crack when dry (FAO, 2006;Gidigasu and Gawu, 2013;Azinwi Tamfuh et al, 2016;Diaz et al, 2016). This pedoturbation is vital in explaining some soil (0 physical features (wide-opened cracks in the dry season, surface ponding in the rainy season, slickensides) and pedogenic processes (Kovda et al, 2017). The void ratios, high at field capacity and low at oven-dry state, are within the limits of 0.30 (moist) and 1.50 (dry) typical of expansive clays, but much higher than values reported for organic horizons (Jones and Holtz, 1973;Sridharan and Nagaraj, 2010).…”

“…The surficial desiccation cracks of vertisols have several indirect effects on the crop performance (Kovda et al, 2017). Due to shrinkage and cracking, the water is not readily available to the roots, although the cracks might favour infiltration of water to deeper parts of the profile following the first rains (Eswaran and Cook, 1988;Pal et al, 2012).…”

“…В настоящий момент выделены следующие основные ареалы распространения слитых и слитизированных почв ЕТР: Северный Кавказ (Ковда, 1992; Хитров, 2003), Среднее и Нижнее Поволжье (Хитров, Роговнева, 2014; Турсина, 1973), Кубано-Приазовская низменность и Тамань (Хитров, Роговнева, 2017; Хитров и др., 2015), а также Центрально-Черноземный регион (Хитров и др., 2013). Наиболее северной (экстремальной) точкой обнаружения слитых почв является Забайкалье (Kovda, 2017).…”

“…Despite the high production potential, vertisol needs adequate management [46] due to difficulty of operating it mechanically. The high moisture content induces clay swelling and intervention for tillage operations cannot be done within the period of liquid and plastic states [47]. This study aimed to evaluate compactness of a no-till vertisol field crop and find spatial correlation between compacted clusters and their physicochemical soil properties through development of a pedotransfer function linking Ss to Pc.…”
