“…At 15–30 cm depth, total N concentration was significantly higher in Sc2 compared to other scenarios. The increase in organic carbon content in surface soil under CA is in accordance with other studies (Lopez-Fando and Pardo 2009; Malecka et al 2012). After 5 years of no tillage in grey pea-barley cropping system, SOC and N concentration was increased by 2.0 and 0.5 Mg ha −1 , respectively at 0–5 cm soil depth in semi-arid Spain (Lopez-Fando and Pardo 2009).…”

“…In Sc3 and Sc4, nutrients accumulated in the surface layer due to retention of higher amounts of residue rich in plant nutrients and minimal soil disturbance, whereas under conventional practices residues were removed and remaining stubbles thoroughly incorporated in the plough layer (0–20 cm) by tillage operations. CA-based practices, particularly conservation tillage are reported to cause greater accumulation of nutrients in surface layer compared to conventional tillage (Holanda et al 1998; Lopez-Fando and Pardo 2009). The concentration of available N in soil under all the scenarios was quite lower than the lower limit of 260 kg N ha −1 which can be attributed to immobilization of inorganic N in soil (Locke and Hons 1988).…”

“…Available Zn at surface soils under Sc2 and Sc4 was statistically at par. The higher available Zn concentration at 0–15 cm soil depth in CA based scenarios (Sc2, Sc3 and Sc4) might be attributed to greater addition of Zn through crop residues and its accumulation in the surface layer (Lopez-Fando and Pardo 2009). In sub-surface layer, concentrations of available Zn were similar under all the scenarios.…”

Soil quality degradation associated with resources scarcity is the major concern for the sustainability of conventional rice-wheat system in South Asia. Replacement of conventional management practices with conservation agriculture (CA) is required to improve soil quality. A field experiment was conducted to assess the effect of CA on soil physical (bulk density, penetration resistance, infiltration) and chemical (N, P, K, S, micronutrients) properties after 4 years in North-West India. There were four scenarios (Sc) namely conventional rice-wheat cropping system (Sc1); partial CA-based rice-wheat-mungbean system (RWMS) (Sc2); CA-based RWMS (Sc3); and CA-based maize-wheat-mungbean (Sc4) system. Sc2 (1.52 Mg m−3) showed significantly lower soil bulk density (BD). In Sc3 and Sc4, soil penetration resistance (SPR) was reduced and infiltration was improved compared to Sc1. Soil organic C was significantly higher in Sc4 than Sc1. Available N was 33% and 68% higher at 0–15 cm depth in Sc3 and Sc4, respectively, than Sc1. DTPA extractable Zn and Mn were significantly higher under Sc3 and Sc4 compared to Sc1. Omission study showed 30% saving in N and 50% in K in wheat after four years. Therefore, CA improved soil properties and nutrient availability and have potential to reduce external fertilizer inputs in long run.

“…However, in semiarid environments, experiments have shown that the tillage practice can affect SOM accumulation (and indeed other soil properties), the outcome is highly site-specific (Ordóñez Fernández et al, 2007;Thomas et al, 2007;Hernanz et al, 2009; Influence of tillage practices on soil biologically active organic matter content over a growing season under semiarid Mediterranean climate Sainju et al, 2009). While some authors report notillage to have a beneficial effect on SOM accumulation (López-Fando & Pardo, 2009;Sombrero & De Benito, 2010), others indicate it to have little or no impact (Thomas et al, 2007;Sainju et al, 2011). The main soil characteristics that determine whether a tillage practice will have a significant influence on SOM accumulation are 1) the initial SOM level, and 2) the texture of the soil (Hassink & Whitmore, 1997;Campbell et al, 2000;Denef et al, 2004).…”

In semiarid areas, traditional, intensive tillage has led to the depletion of soil organic matter, which has resulted in reduced soil fertility. The aim of the present work was to evaluate the effects of different soil management systems, practised over 12 years, on soil organic carbon (SOC), nitrogen (SN) and biologically active organic matter [particulate organic matter (POM); potentially mineralisable nitrogen (PMN); microbial biomass (MB)]. A Mediterranean Alfisol, located in central Spain, was managed using combinations of conventional tillage (CT), minimum tillage (MT) or notillage (NT), plus a cropping background of either continuous wheat (WW) or a fallow/wheat/pea/barley rotation (FW). Soil was sampled at two depths on four occasions during 2006-2007. The results showed the sampling date and the cropping background to significantly affect the SOC (p < 0.0057 and p < 0.0001 respectively). Tillage practice, however, had no effect on SOC or SN. The C-and N-POM contents were significantly influenced by the date, tillage and rotation. These variables were significantly higher under NT than CT and under WW than FW. The PMN was influenced by date, tillage and rotation, while C-MB was significantly affected by tillage (p < 0.0063), but not by rotation. The NT plots accumulated 66% C-POM, 60% N-POM, 39% PMN and 84% C-MB more than the CT plots. After more than 12 years, the benefits of conservation practices were found in the considered soil properties, mainly under no tillage. In order to obtain a consistent data set to predict soil biological status, it is necessary further study over time.

Tillage and nitrogen (N) application influence soil-chemical properties and crop productivity. In a long-term (76-yr) wheat (Triticum aestivum L.)-fallow system in northeast Oregon, we assessed the effects of tillage (subsurface-sweep, sweep; offsetdisk, disk; and moldboard plow, plow) and N application rates (0, 90, and 180 kg N ha −1 ) on soil organic matter (SOM), soil-chemical properties in 0-to-30-cm soil profile, and wheat yields. Sweep and disk exhibited more pronounced vertical gradient in soil chemical properties within the 0-to-30-cm soil profile than plow due to shallow soil mixing. Across N rates, at 0-to-10-cm depth, sweep and disk had lower pH (0.60), calcium (Ca; 0.32 g kg −1 ), magnesium (Mg; 83 mg kg −1 ), and estimated cation exchange capacity (CECe; 1.8 cmol kg −1 ), but higher SOM (9 g kg −1 ) and aluminum (Al; 26 mg kg −1 ) than plow. Below 10 cm, plow had lower pH (0.67-0.83), Ca (0.29-0.31 g kg −1 ), and CECe (1.7-1.8 cmol kg −1 ), but higher Al (13-16 mg kg −1 ) than disk and/or sweep. Across tillage treatments and depths, pH, Ca, Mg, and CECe generally decreased, whereas phosphorus, potassium, and Al increased with increasing N rates. Wheat yields increased by 14% from N application but did not differ between 90 and 180 kg N ha −1 . Sweep and disk produced 9% less wheat yield than plow. Long-term N application and grain removal of basic cations resulted in surface soil acidification under sweep and disk, which if not remedied, can decrease wheat productivity in this region.Abbreviations: CECe, estimated cation exchange capacity; iPNW, inland Pacific Northwest; N 0 , 0 kg N ha −1 ; N 180 , 180 kg N ha −1 ; N 90 , 90 kg N ha −1 ; SOM, soil organic matter; WW-F, winter wheat-fallow system.
