“…They mainly differed at the end of the sampling period in total organic carbon content (10.9, 13.1, and 13.2 g·kg −1 ), volumetric soil water content (0.19, 0.23, and 0.25 cm 3 ·cm −3 ), total N (1.23, 1.30, and 1.46 g·kg −1 ), and Olsen available P (37.2, 32.5, and 39.9 mg·kg −1 for the CT-, DS-, and DSC-soils, respectively). The differences were significant for all these parameters in the three soils, and positive correlations had previously been found between the amount of soil microorganisms and the organic carbon or water content [39].…”

Evaluation of the Microbial Viability of Soil Samples from Maize Crops in Freeze-Storage under Different Management Conditions in a Semi-Arid Climate

Abstract:The effect of freeze-storage on culturable soil microorganism viability was determined for soil samples from three agricultural maize crop systems (under conventional management, direct seeding, and direct seeding with a cover crop). Most culturable soil bacteria were unaffected by the freeze-thaw stress or the prolonged freeze-storage, but the viability of mold and Bacillus mycoides populations decreased drastically after eight months of freeze-storage, limiting the process sustainability to this period. However, these changes did not significantly affect either the total microorganism biodiversity index or the biodiversity differences between treatment. Based on the available results, freeze-storage seems to be a sustainable process for up to eight months that can be allowed in analyses of culturable microbial population biodiversity.

“…Benjamin (1993) and Baumhart & Lescano (1996) indicated that soils under no-tillage treatment have greater infiltration rates and water storage capacities than tilled soils. Conservation tillage was also shown to improve soil water content and crop yields in many environments (Radford et al 1995;Hemmat & Eskandari 2004;Munoz et al 2007), but Wilhelm et al (1987) and Hammel (1995) observed negative effects of no-tillage on crop yields in arid areas of the United States.…”

Water is the most limiting factor for crop production in dryland farming. A better understanding of the long-term impact of tillage and residue management systems on soil structure and water infiltration is necessary for the further development of conservation tillage practice to improve water use efficiency. The objectives of this study were to assess the influence of no-till with residue retention (NT) and conventional (plough) tillage with residue removal (CT) on soil properties and soil water transmission characteristics in a winter wheat (Triticum aestivum) monoculture system in Shanxi, on the Chinese Loess Plateau. Soil physical parameter measurements were made in the top 30 cm depth in September 2007 after 16 years under the two tillage treatments. Compared with CT treatment, NT significantly (P < 0.05) reduced soil bulk density (7.1%) in the 20-30 cm soil layer, and increased macroporosity (>60 µm, 17.0%) and saturated hydraulic conductivity (249%) in the 15-30 cm soil layer. There were no significant differences in these soil physical properties between tillage systems in the 0-15 cm layer. In addition, plant available water and water infiltration rate were greater in the NT treatment. The improved soil quality parameters and water infiltration from this long-term experiment indicate that no-tillage with residue retention is a promising farming system for the dryland farming areas of northern China.

“…Villamil et al (2006) also found the same effect with rye and vetch. In a semi-arid region in Spain, Muñoz et al (2007) showed an increase in soil aggregate stability by using oats as a CC. In our study, barley and vetch increased WSA at 54 DAS maize; the differences disappeared at 69 DAS, although the trend remained.…”

“…The shift to more sustainable agricultural practices such as minimum tillage or including winter cover crops (CC) in the last decades is improving soil structure and protecting the soil from wind and water erosion. Cover cropping also enhances soil organic matter (SOM) content, aggregation stability and microbial activity (Ding et al, 2006;Kabir and Koide, 2000;Mendes et al, 1999;Muñoz et al, 2007;Veenstra et al, 2007). However, in semiarid climate areas with limitations of water availability and nutrients uptake, the benefits of CC establishment do not seem to be clear, showing in some cases reductions in the main crop yield (Lascano et al, 2015;Salmerón et al, 2010).…”

“…Total organic carbon (TOC) content is a soil quality indicator that is affected by the changes in the crop management such as intensive tillage and the addition of crop residues to the soil (Chavarría et al, 2016;Muñoz et al, 2007;Nivelle et al, 2016;Veenstra et al, 2007;Villamil et al, 2006). Benefits in soil structure are related to its accumulation in the soil and an increase in the formation and stabilization of soil microaggregates and macroaggregates (Beare et al, 1994).…”
