“…Similar results were also reported by Hill (1990) and Mahboubi et al (1993). Some authors have finally suggested that tillage practices can also alter soil physical properties and, consequently, the surface and subsurface hydrology of agricultural fields, especially when a similar tillage system has been practiced for a long period (Buschiazzo et al, 1998;Gómez et al, 1999;Hill, 1990;Özgöz et al, 2007;Tsegaye and Hill, 1998).…”

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.

“…Rainfall-induced soil erosion risk in the Mediterranean is especially high during summer storms or the early wet season, when plant cover is low (García-Orenes et al, 2009;Taguas et al, 2015). Soil loss is enhanced in cropped soils due to soil management and tillage practices (Blavet et al, 2009;Boardman et al, 1990;Boix-Fayos et al, 2005;Cerdan et al, 2010;Gómez et al, 1999;Vanwalleghem et al, 2011). Indeed, this is due to several reasons such as conventional plowing, removal of the original vegetation, use of pesticides and herbicides that damage biological activity in soils (Freemark and Boutin, 1995;Johnsen et al, 2001;Pelosi et al, 2013), low overall vegetation cover, soil compaction and sealing due to machinery traffic, depletion of organic matter and absence of soil erosion control measures (Arnáez et al, 2015;Bakker et al, 2005;Carr et al, 2015;Cerdà et al, 2009;Ciampalini et al, 2012;Cots-Folc et al, 2009;Laudicina et al, 2015;Raclot et al, 2009;Tarolli et al, 2014Tarolli et al, , 2015.…”

“…Conventional tillage practices alter soil structure and increase porosity of the upper layer. This increases the initial water infiltration into the soil, but total infiltration is often decreased by subsoil compaction (Aina et al 1991;Azooz and Arshad 1996;Gómez et al 1999). Cultivated soils may lose a lot of rainfall as run-off and large amounts of soil through erosion (Duley 1940).…”

Conservation agriculture involves reduced tillage, permanent soil cover and crop rotations to enhance soil fertility and to supply food from a dwindling land resource. Recently, conservation agriculture has been promoted in Southern Africa, mainly for maize-based farming systems. However, maize yields under rain-fed conditions are often variable. There is therefore a need to identify factors that influence crop yield under conservation agriculture and rain-fed conditions. Here, we studied maize grain yield data from experiments lasting 5 years and more under rain-fed conditions. We assessed the effect of long-term tillage and residue retention on maize grain yield under contrasting soil textures, nitrogen input and climate. Yield variability was measured by stability analysis. Our results show an increase in maize yield over time with conservation agriculture practices that include rotation and high input use in low rainfall areas. But we observed no difference in system stability under those conditions. We observed a strong relationship between maize grain yield and annual rainfall. Our meta-analysis gave the following findings: (1) 92% of the data show that mulch cover in high rainfall areas leads to lower yields due to waterlogging; (2) 85% of data show that soil texture is important in the temporal development of conservation agriculture effects, improved yields are likely on well-drained soils; (3) 73% of the data show that conservation agriculture practices require high inputs especially N for improved yield; (4) 63% of data show that increased yields are obtained with rotation but calculations often do not include the variations in rainfall within and between seasons; (5) 56% of the data show that reduced tillage with no mulch cover leads to lower yields in semi-arid areas; and (6) when adequate fertiliser is available, rainfall is the most important determinant of yield in southern Africa. It is clear from our results that conservation agriculture needs to be targeted and adapted to specific biophysical conditions for improved impact.
