“…Similar observations in SOC, TN and BD were also reported in previous studies [4]; however, there were different variation rules for soil nutrients [30]. The different changes in soil characteristics caused by the tillage management influence may be related to environmental conditions, soil conditions and the time of the experiment [31,32].…”

“…Meanwhile, RT had significantly higher SWC than that under PT and ST, which was mainly due to the tillage operation resulting in the different distribution of soil aggregates and soil texture [40]. Previous studies showed that different tillage management methods caused soil properties to vary greatly [32]. In the present study, the AK, AP and TP varied greatly with the deepening of the soil layer under different tillage management, while the TK had no significant difference in the four depths.…”

Tillage management is a direct factor in affecting soil quality, which is a key factor in sustainable agriculture. However soil quality evaluation needs significant manpower, material resources and time. To explore the sensitive indicators of soil quality affected by tillage management, eight soil physical and chemical properties under three tillage managements, including plow tillage, subsoiling tillage and rotary tillage, were determined under a long-term experiment in North China Plain. The results showed that subsoiling tillage management had the highest soil organic carbon and total nitrogen in the 0–20 cm layer and the lowest soil bulk density in the 30–40 cm layer. Rotary tillage management had the highest soil water content in the 0–40 cm layer. Meanwhile, compared to 2002, the soil organic carbon, total nitrogen and soil bulk density had varied greatly in 2012, but there was no significant difference between 2012 and 2018. However, other property concentrations tended to increase in 2002, 2012 and 2018. In addition, there was a significant linear relationship between soil quality index and grain yield. Subsoiling tillage management had the highest soil quality index and gain yield both in 2012 and 2018. The soil quality can be evaluated through the sensitive indicator of soil organic carbon, total nitrogen, soil bulk density, total phosphorus and soil water content, which provides a scientific basis for selecting reasonable tillage management and evaluating soil quality in this agricultural production area or other similar areas.

“…Others (Godsey et al, 2007;Sainju & Alasinrin, 2020) reported that crop rotation increased soil pH and Al concentration compared with monocropping. In contrast, Mikha et al (2020) found that crop rotation had no effect on soil chemical properties.…”

“…Crop rotation has a favorable effect on crop yields compared with monocropping. Crop yields were greater with crop rotation than monocropping (Lin & Chen, 2014; Lopez‐Bedillo et al., 2000; Mikha et al., 2020). Some researchers (Carr et al., 2006; Lenssen et al., 2007; Stevenson & van Kessel, 1996) reported that spring wheat–pea rotation increased spring wheat yield by 13–30% compared with continuous spring wheat in dryland cropping systems in the northern Great Plains.…”

Information on the effect of no-till crop rotation on a broad range of soil properties and long-term crop yields is needed to evaluate its benefits on ecosystem services compared with monocropping. The objective of this study was to examine the effects of no-till crop rotation (barley [Hordeum vulgare L.]/spring wheat [Triticum aestivum L.]-pea [Pisum sativum L.]) and monocropping [continuous barley/spring wheat] on 66 dryland soil physical, chemical, biological, and biochemical properties and longterm crop yields at two dryland farm sites (14-and 36-yr old) in the northern Great Plains. Soil samples collected to a depth of 15 cm in April 2019 were analyzed for soil properties and crop yields determined. At the long-term site, crop rotation increased 11 properties, but reduced 16 of 66 soil properties compared with monocropping.At the short-time site, crop rotation increased 6 properties, but reduced 13 of 66 soil properties compared with monocropping. Longer duration experiments showed more differences in soil properties due to crop rotation than shorter duration experiments. Spring wheat and barley yields were greater following pea than following spring wheat or barley during years with normal or above-average precipitation at both sites. Pea yield in the crop rotation was also greater during these years. Barley/spring wheat-pea rotation can enhance some soil properties and dryland crop yields compared with continuous barley/spring wheat during wet years in the semiarid region of the northern Great Plains.

Precision management (PM) aims to reduce inputs while increasing land productivity and economical return and enhancing cropping system resiliency to climate change. This study evaluated how climate (precipitation) and management influenced yields and soil nutrients in a dryland agricultural system. We compared an “aspirational” (ASP) system (no‐till, 4‐year rotation of winter wheat [Triticum aestivum L.], corn [Zea mays L.], proso millet [Panicum miliaceum L.], and fallow/flex) to a traditional “business‐as‐usual” (BAU) system (reduced tillage, 2‐year rotation of winter wheat and fallow: W–F). Phases of each rotation were included yearly throughout the study period (2018–2022) with three replications. The ASP system incorporated PM by dividing each ASP field into three zones (high‐, medium‐, and low‐PM) according to prior yield and topography. Nitrogen was applied at high, medium, or low application rates within those zones. Under favorable precipitation, wheat, corn, and millet yields responded to PM treatments, with yields increasing proportional to N addition. Years with low in‐season precipitation had a significant reduction in wheat and corn yields (2020 and 2022) and complete millet yield failures (2020 and 2021). Low soil organic matter accumulation (0.1%–0.5%) and a reduction in soil macro‐ and micronutrient status suggested that soil nutrient additions are needed to prevent soil‐nutrient degradation. The ASP treatment added a third crop every 4 years and did so without significantly decreasing wheat yield following fallow. The ASP management shows promise as an alternative to BAU in the Great Plains dryland production region.
