“…2) within soil of Al-Khairat site, and the treatments (T13, T19, T21) within soil of Al-Kamaliya site,(Fig. 1) which were the best treatments, As the cracks disappeared completely.This effect was more pronounced within the soils of Al-Khairat site compared to the soil of Al-Kamaliya site, although their numbers within soil of Al-Khairat in general were higher, This variation in the numbers of cracked masses within the soil of the two sites may be due to the small perimeter of the cracked masses formed within soil of Al-Khairat site compared to soil of Al-Kamaliya site , as there is an inverse proportion between perimeter of the masses and their number for same measured area (6). The reason for the decrease in the number of masses may also be due to the high content of clay particles in the soil of Al-Khairat site compared to the soil of Al-Kemaliya site.…”

This study was conducted to show the effect of cows' manure, date palm residues, sand fraction and the interactions between them in treating the common cracking phenomenon in some soils of holy karbala governorate, and their role in improving some of the physical characteristics of those soils, represented in soil aggregates stability, modules of rupture, and linear expansion coefficient.Two agricultural sites were selected whose soils are characterized by heavy clay textures and widespread of cracking phenomenon within the holy Karbala governorate, the first was in Al-Kamaliya area and the second in Al-Khairat area. The results, showed a decrease in number of cracked masses, and their sizes in both studied soils. with an increase in levels of addition of animal manure, and plant residues and sand,and reached to lowest in treatments in which cracks disappeared while the highest values of mean weight diameter were reached in the treatments in which cracks disappeared for the soil of two study sites. Results showed that the decreased values of modules of rupture and linear expansion coefficient of soil with increasing the rates of addition and reaching to the lowest values in the treatments in which cracks disappeared compared to reference treatment.

“…Recent studies have tended in many countries around the world to search for new means and methods to improve soil structure, organic carbon and moisture conservation by making use of the remains of previous crop (El-Naggar et al, 2018) or adding agricultural residues and animal waste (Fan and Wu, 2020) and adding some low-cost natural rocks as phosphogypsum or lime (Borselli et al, 1996 andAl-Nasser andAl-Khalid, 2020) to improve soil health and its sustainability (Choudhury et al, 2014, Opoku-Kwanowaa et al, 2020.…”

Most of the agricultural soils around the world suffer from increased soil degradation and erosion and reduce moisture conservation, which is the decisive factor in agricultural crop production, and among these problems is the phenomenon of Surface Soil Crusting (SSC), which is spread in a wide range of climates, especially in dry and semi-arid soils. In this review, the focus was done on the significance of SSC, its formation mechanisms, stages of emergence, types of crusts, methods used to estimate crust hardness and its resistance to penetration. It was noted that SSCs are formed when raindrop falls on newly plowed soils or soils without vegetation, followed by periods of drought, thus destroying soil aggregates and splashing there fine particles, these particles enter the inter-pores, Leading to formation of hard thin layers at the soil surface with thickness ranges from several millimeters to several centimeters or these particles moved by surface runoff water to deposit in the bottom of valleys, forming a sedimentary crust of five to seven centimeters thick. The SSC are generally divided into three main parts, namely, structural crusts, sedimentional crusts, in addition to the Biological soil crusts, which is formed over the previous two types and consists of fungi, algae, lichens and bacteria. Crust hardness can be measured or estimated by two main methods, which are Modulus of Rupture, and crust Penetration Resistance.
