“…Bulk density, has been observed to increase (Li et al, 2007;Soane et al, 2012;Mbuthia et al, 2015;Blanco-Canqui and Ruis, 2018;Somasundaram et al, 2019), decrease (Hansen et al, 2012;Mrabet et al, 2012;Blanco-Canqui and Ruis, 2018), and be no different under CA systems (Dalal et al, 2011;Zhang et al, 2014;Blanco-Canqui and Ruis, 2018), with differences between studies largely due to soil type, duration of the study and time of sampling. However, a recent global meta-analysis found that NT with residue retention, on average increased bulk density by 1.4% (Li et al, 2019b).…”

“…In soils that are depleted of organic matter, aggregates are more likely to slake into smaller sub-units during wetting, resulting in a soil structure that is more likely to erode and which can limit water infiltration and the emergence of seedlings (Tisdall and Oades, 1982;Blanco-Canqui and Ruis, 2018). Where CA increases SOC, associated improvements in soil aggregate stability are typically observed (Blanco-Canqui and Ruis, 2018; Li et al, 2019b). Greater fungal populations and the persistence of root networks in the absence of tillage in particular have a positive effect (Wang et al, 2010;Spurgeon et al, 2013).…”

“…Greater fungal populations and the persistence of root networks in the absence of tillage in particular have a positive effect (Wang et al, 2010;Spurgeon et al, 2013). As a reflection of this, a recent worldwide meta-analysis observed that, on average, the number of water stable aggregates in NT systems are 31% greater compared to conventionally tilled systems without residue retention (Li et al, 2019b). These improvements are important as they lead to greater rates of soil water infiltration, provide increased resistance to wind and water erosion (in combination with residue retention), improve the physical protection of organic matter and provide greater abundance of habitats to support microbial activity (Helgason et al, 2010;Spurgeon et al, 2013;Blanco-Canqui and Ruis, 2018;Li et al, 2019b).…”

“…Improved aggregate stability, combined with the residue retention in CA systems, is often observed to have a significant positive impact on soil water storage (for examples see Table 2). These increases typically occur due to a combination of greater rates of infiltration and decreased soil water evaporation (Li et al, 2019b). Increases in infiltration are commonly attributed to the improved aggregate stability in the surface of the profile (where improvements in SOC are highest) and the greater number and continuity of macropores available to rapidly transmit water into the soil profile in the absence of tillage (Blanco-Canqui and Ruis, 2018; Li et al, 2019b).…”

The presence of crop residues can also help protect the surface of the soil from raindrop impact and prevent the formation of surface seals, which can decrease infiltration rates (McGarry et al, 2000).…”

Increases in human populations and the emerging challenges of climate change mean that the world's agricultural systems will need to produce more food in an environment that is increasingly variable and where the quality of our natural resource base is declining. One central measure of an agricultural system's capacity to do this is its ability to preserve soil organic carbon (SOC), due to the pivotal role that this plays in maintaining soil physical, chemical, and biological properties and ultimately yield. This narrative review examines the literature published worldwide over the last 30 years to assess the impact of one widely applied agricultural management system, conservation agriculture (CA), on its ability to maintain SOC and the subsequent impacts on soil physical, chemical and biological properties, and yield. While the effects of CA on SOC worldwide are variable, with both increases and decreases observed, in regions where soil and climatic conditions are favorable for biomass production and where the system does not negatively impact yield, then CA can lead to higher amounts of SOC relative to conventionally managed systems, particularly in the surface of the soil profile. Where greater SOC occurs, these are also often accompanied by improvements in soil structure, water infiltration and soil water storage, plant nutrient availability, microbial biomass and diversity, and yield. However, where CA is used in certain environments (e.g., cold, wet environments with poorly drained soils) or where the CA system has not been well-adapted to local conditions, taking into account the specific agronomic, social, and environmental challenges present, then it may not be a successful system of management. Farmers require access to a range of tools and resources to allow them to identify if the principles of CA are likely to lead be appropriate for their situation and well-designed, locally adapted systems to successfully overcome the agronomic, social and economic challenges that can be associated with its use.

The main objective of the present study was to investigate changes in soil organic carbon (SOC), pH, as well as macro-and micronutrient concentrations in the top 0to-5-and 5-to-15-cm soil depths under no-tillage (NT) and conventional tillage (CT) practices at different nitrogen (N) application rates. The soil analysis was conducted in 2019 and 2020 from CT and NT treatments from a long-term study conducted near Hays, KS, with N fertilizer rates of 0, 45, 90, and 134 kg N ha −1 . Averaged across years, SOC in the top 0-to-5-cm soil depth under NT was 19% greater than that measured in CT, but SOC was not different between the two tillage practices in the 5-to-15-cm depth. The SOC concentration increased by 24-25% within the top 0-to-5-cm soil depth with increasing N rate from 0 to 90 or 134 kg N ha −1 . Soil pH declined at rates of 0.004 and 0.007 for every kg ha −1 increase in N rate for CT and NT treatments within the 0-to-5-cm soil depth. Nitrate-N concentration under NT at the top 0-5 cm soil was 55% more than CT but ammonium-N concentration was unaffected by tillage or N rate. Phosphorus (P), zinc (Zn), and iron (Fe) concentrations measured in the top 0-5 cm were 24, 34, and 33% greater in soils under NT compared with CT, respectively. Findings of the study suggest pH and SOC stratification in long-term NT systems can affect soil macro-and micronutrient concentrations and availability in dryland crop production systems.
