“…Consequently, the land cover type was later found to have a significant effect on Ksat. is phenomenon is not unusual because it is not unusual to obtain variation in Ksat depending on the depth and the method in use [88], type of soil, for example, sandy versus clayey soils [86], land use practice [89], type of vegetation, and landform [90].…”

Soil properties contribute to the widely recognised resilience of semiarid areas. However, limited attention has been given in providing a scientific basis of how semiarid soil properties in the various land covers occur and how they influence forage quantity.is study investigated the influence of different soil properties and land cover types on herbaceous biomass quantity in the Karamoja subregion of Uganda. A completely randomized design in three land cover types (thickets and shrublands, woodlands, and savannah grasslands) was implemented. In each vegetation type, 50 × 40 m plots were demarcated with nested plots to facilitate clipping of the herbaceous layer. Composite soil samples at two depths (0-15 cm, 15-30 cm) were obtained from each plot. e results showed that soil properties varied across land cover types. Soil pH ranged between 6.9 and 8.1 and SOM, N, P, and K were generally low in all land cover types. Soil hydraulic properties revealed the existence of rapid to very rapid permeability in thickets/shrublands, grasslands, and woodlands. Percent change in soil properties (0-15 cm to 15-30 cm) was highest in P, Ca, Mg, Na, and SOM. In the grasslands, P positively (p ≤ 0.01) influenced herbaceous biomass, whereas pH, K, Na, % sand, and % clay, N, and SOM had a negative relationship with herbaceous biomass (p ≤ 0.05). Herbaceous biomass in the thickets/shrublands was negatively influenced by P, Ca, and Mg and % clay and positively by N and % silt (p ≤ 0.05). Only N and SOM were significant determinants of herbaceous biomass in the woodlands (p ≤ 0.05). e low level of soil nutrients observed in this study reveals the fragility of semiarid soils, indicating the need for sustainable landscape management.

“…This suggested that the ability of soil water absorption was not only affected by the degree of soil water repellency as indicated by RI. The main reason is that RT treatment improved soil pore structure and water transmission (Gao et al, 2019;Li et al, 2021;Sauwa et al, 2013), which attenuated the effect of the increase in RI on soil water absorption.…”

Abstract. Drought is increasingly common due to frequent occurrences of extreme weather events, which further increases soil water repellency (SWR) and influences grain yield. Conservation agriculture is playing a vital role in attaining high food security and it could also increase SWR. However, the relationship between SWR and grain yield under conservation agriculture is still not fully understood. We studied the impact of SWR in 0–5 cm, 5–10 cm, and 10–20 cm layers during three growth periods on grain yield from a soil water availability perspective using a long-term field experiment. In particular, we assessed the effect of SWR on soil water content under two rainfall events with different rainfall intensities. Three treatments were conducted: conventional tillage (CT), reduced tillage (RT), and no-tillage (NT). The results showed that the water repellency index (RI) of NT and RT treatments in 0–20 cm layers was increased by 12.9 %–39.9 % and 5.7 %–18.2 % compared to CT treatment during the three growth periods, respectively. The effect of the RI on soil water content became more obvious with the decrease in soil moisture following rainfall, which was also influenced by rainfall intensity. The RI played a prominent role in increasing soil water storage during the three growth periods compared to the soil total porosity, penetration resistance, mean weight diameter, and organic carbon content. Furthermore, although the increment in the RI under NT treatment increased the soil water storage, grain yield was not influenced by RI (p > 0.05) because the grain yield under NT treatment was mainly driven by penetration resistance and least limiting water range (LLWR). The higher water sorptivity increased LLWR and water use efficiency, which further increased the grain yield under RT treatment. Overall, SWR, which was characterized by water sorptivity and RI, had the potential to influence grain yield by changing soil water availability (e.g. LLWR and soil water storage) and RT treatment was the most effective tillage management compared to CT and NT treatments in improving grain yield.

“…Moroke et al, (2009) also observed higher IR in DT than CT due to ample amount of macropores which led to the fast entry of water into the soil profile. The effect of tillage-residue management practices on cumulative infiltration (CI) is presented in Fig 2. After 300 minutes, maximum CI (cm) was observed under DT (33.1) followed by NTR (28.5), NT (23.0) might be due to relatively smaller pore heterogeneity and discontinuity of pores (Sauwa et al,. 2013).…”

A field study was conducted to evaluate moisture storage in soil profile under four tillage-residue management practices namely conventional tillage, no-tillage without residue, no-tillage with residue and deep tillage along with three irrigation regime based on IW/PAN-E ratio 1.2, 0.9 and 0.6 in maize with three replications in split plot design. Significant differences were observed in steady state infiltration rate and cumulative infiltration among different land management practices with maximum value in deep tillage (4.9 cm hr -1 and 33.1 cm) followed by no tillage with residue (4.1cm hr -1 and 28.6 cm), no tillage without residue (4.0 cm hr -1 and 23.0 cm) and conventional tillage (2.8 cm hr -1 and 19.4 cm), respectively. The highest mean weight diameter and water stable aggregates were found under no tillage with residue (0.64 mm and 49.7%) and lowest under deep tillage (0.3 mm and 21.8%), respectively. Higher volumetric soil water content and soil profile moisture storage were recorded under no tillage with residue at different days after sowing. Among different tillage-residue management practices, maximum leaf area index and relative leaf water content were observed in no-tillage with residue. Under moisture stress conditions, no-tillage with residue retention was suitable land management option for reducing evaporation losses and enhancing moisture storage in the soil profile.
