“…This is coincident with these results that GMD values with the straw incorporation treatments improved significantly throughout under 3 yr study . Improvement in stability of soil aggregates with NT may endorsed obviously near to the surface soil (< 10 cm) (Stone and Schlegel, 2010;Kahlon et al, 2013). In this study, we found distinct difference in GMD at surface soil, the distinct difference could be related with the continuous organic matter placement in the surface soil, the high stable soils always characterized due high addition of soil organic matter (Sandoval et al, 2007;Paul et al, 2013).…”

“…The soil management practices are considered essential to conserve soil quality (Kahlon et al, 2013), and can greatly affect the composition and stability of SOC through plough layer (Stone and Schlegel, 2010;Bhattacharyya et al, 2012;Ghosh et al, 2016). Conventional tillage (CT) could reduce the SOC content and accelerate SOC oxidation rate, probably due to the disturbance of soil aggregates and the increase of the soil aeration (Gathala et al, 2015).…”

No-tillage and straw returning are important practices for preserving and improving soil quality for the sustainable management system. The experimental field was established in 2007 with conventional tillage (CT), conventional tillage with straw returning (CTS), no-tillage (NT), and no-tillage with straw returning (NTS) practice in rice (Oryza sativa L.)-rape (Brassica napus L.) cropping system. The soil samples were collected in 2013-2015 from 0-20 and 20-40 cm depth to investigate the effects on soil organic C (SOC), water-stable aggregation (> 5, 5-2, 2-1, 1.0-0.5, 0.25-0.5, and < 0.25 mm), and their stability in paddy soil of the central China. In the last year (2015), the integrative use of no-tillage and straw returning significantly increased SOC content and contribution of the macroaggregates in 0-20 cm and microaggregates in 20-40 cm depth. Compared with CT, SOC content, mean weight diameter (MWD), geometric mean diameter (GMD), and fractal dimensions (FD) under NTS were increased 25%, 21%, 19%, and 12%, respectively, in the 0-20 cm depth. In 20-40 cm depth, the soil micro-aggregates were higher under CTS treatment. Percentages of macroaggregates and microaggregates under NTS were increased 60% and 40% in the 0-20 cm depth. The SOC had positive linear relationship with MWD, GMD, > 5, 2-5, 1-2, and 0.25-0.5 mm aggregates. Thus, long-term combine use of NT with straw returning practices significantly improved SOC and water-stable aggregation. No-tillage and straw returning appeared to be promising and sustainable strategies to conserve SOC sequestration and stable soil aggregates in rice-rape cropping system.

“…The main contribution of NT practices to increasing dryland crop yield is through increased soil water availability which comes through decreased water evaporation at the soil surface and improved soil physical properties such as infiltration rate, hydraulic conductivity, aggregate stability, microporosity, and water holding capacity. Previous data showed higher soil water contents at -1.5 Mpa matric potential, increased size and weight of water stable aggregates, and increased ponded steady state infiltration for NT compared with RT or CT (Stone and Schlegel, 2010). Recently, a relatively greater cumulative runoff during fallow period after sorghum and wheat was reported for NT (57 mm) compared with stubble mulch tillage, 33 mm (Baumhardt et al, 2017).…”

Core Ideas Average sorghum yield advantage was 120% for no tillage over conventional tillage and 55% for reduced tillage over conventional tillage.Average wheat yield advantage was 31% for no tillage over conventional tillage and 12% for reduced tillage over conventional tillage.Available soil water at planting in soil profile was less for conventional tillage than both no tillage and reduced tillage for both crops.There was a decline in wheat yield over time due to increased seasonal temperature. Tillage is among crop management factors that affect yield, profitability, and environmental quality. The objective of our study was to evaluate the effect of three long‐term tillage intensities; conventional tillage (CT), reduced tillage (RT), and no‐till (NT), on winter wheat (Triticum aestivum L.) and grain sorghum (Sorghum bicolor L.) yield, available soil water (ASW), and water productivity. The study was conducted near Tribune, KS, from 1991 through 2015 in a wheat–sorghum–fallow (WSF) rotation. The CT plots were tilled (primarily with a sweep plow), on average, four to five times per fallow season; NT plots used herbicides for weed control during fallow. The RT plots used a combination of herbicides and tillage for weed control during fallow prior to both crops for years 1991 to 2000; and, for the years 2001 to 2015, the RT system was NT before sorghum planting (short‐term NT) and CT before wheat planting. On average, there was a 31% wheat yield advantage for NT over CT, 16% NT over RT, and 12% RT over CT. On average, there was a 120% sorghum yield advantage for NT over CT, 41% NT over RT, and 55% RT over CT. Sorghum yields were 80% greater for continuous NT compared with short‐term NT (2001–2015 RT). The average of profile ASW at planting was less for CT compared with NT and RT. There was a significant yield and water productivity benefit in the order NT > RT > CT for both crops, but greater for sorghum than wheat.
