“…Further, the tillage-induced disturbance and the pulverizing effect under conventional tillage and deep tillage produce a finer and loose soil structure, which has fewer retention pores than in no-tillage with residue. Soil disturbance and tillage frequency decreases volumetric water content (Hussain et al, 1998). As in this study, the increase in soil moisture with depth was also reported by Dao (1993); Kahlon et al (2012); Kebede and Bekelle (2008).…”

A b s t r a c t. Tillage practices affect mechanical and hydrological characteristics of soil and subsequently the least limiting water range. This quality indicator under the wheat-maize system of northwest India has not been studied yet. The treatments included four tillage modes, namely conventional tillage, no-tillage without residue, no-tillage with residue, and deep tillage as well as three irrigation regimes based on the irrigation water and pan evaporation ratio i.e. 1.2, 0.9, and 0.6. The experiment was conducted in a split plot design with three replications. At the end of cropping system, the mean least limiting water range (m 3 m -3 ) was found to be highest in deep tillage (0.26) and lowest in notillage without residue (0.15). The field capacity was a limiting factor for the upper range of the least limiting water range beyond soil bulk density 1.41 Mg m -3 and after that 10% air filled porosity played a major role. However, for the lower range, the permanent wilting point was a critical factor beyond soil bulk density 1.50 Mg m -3 and thereafter, the penetration resistance at 2 MPa becomes a limiting factor. Thus, deep tillage under compaction and no-tillage with residue under water stress is appropriate practice for achieving maximum crop and water productivity.K e y w o r d s: least limiting water range, tillage, maize, wheat, soil moisture, crop productivity INTRODUCTION

“…Other studies also reported that soil bulk density was greater in no-till in the 5-10 cm soil depth as compared to tillage (Grant and Lafond, 1993;Osunbitan et al, 2005;Radcliffe et al, 1988;Rhoton et al, 1993;Strudley et al, 2008;Wander and Bollero, 1999;Hussain et al, 1998).…”

“…Hussain et al (1998) noted higher water content within a no-tillage system than within conventional tillage. In a 20-year study, Sharratt et al (2006) reported that no-tillage had greater soil penetration resistance and water content compared to all other tillage treatments.…”

A b s t r a c t. Soil and crop management practices can affect the physical properties and have a direct impact on soil sustainability and crop performance. The objective of this study was to investigate how soil physical properties were affected by three years of tillage, cover crop and crop rotation treatments in a corn and soybean field. The study was conducted on a Waldron siltyloam soil at Lincoln University of Missouri. Soil physical properties studied were soil bulk density, volumetric and gravimetric water contents, volumetric air content, total pore space, air-filled and water-filled pore space, gas diffusion coefficient and pore tortuosity factor. Results showed significant interactions (p<0.05) between cover crop and crop rotation for bulk density, gravimetric and total pore space in 2013. In addition, cover crop also significantly interacted (p<0.05) with tillage for bulk density and total pore space. All soil physical properties studied were significantly affected by the depth of sampling (p<0.0001), except for bulk density, the pore tortuosity factor and total pore space in 2012, and gravimetric and volumetric in 2013. Overall, soil physical properties were significantly affected by the treatments, with the effects changing from one year to another. Addition of a cover crop improved soil physical properties better in rotation than in monoculture.

“…Tillage induced disturbance and the pulverizing effect of CT produced a finer and loose soil structure which had lower retention pores than NT (Rashidi and Keshavarzpour, 2007). The NT system conserved more moisture probably because of the retention of crop residues on the soil surface, interception of rainfall, reduction of runoff, and an increase of available water capacity as compared to CT. Hussain et al(1998) stated that as the soil disturbance and tillage frequency increased, θ decreased. There are several practices (i.e.…”

“…The combination of mulching with tillage in conserving soil moisture has been recognized by many researchers (Greverset al, 1986, Van Ouwerkerk 1986and Bhagat and Acharya 1988. Hussain et al (1998) the intensity of soil disturbance and tillage frequency increases volumetric soil moisture content decreased. Lafond et al (1992) reported that NT increase the water storage capacity of the soil and increase the available water for crop growth.…”

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.
