“…Higher SOC in the surface 0-5 cm soil layer observed in our study is in conformity with previous studies which showed surface-layer (0-5 cm) increments of SOC content in NT than RT [8,28,43,44]. The increase in SOC concentration with reversal of tillage was closely associated with enhanced decomposition of incorporated crop residues.…”

Effect of conservation tillage on crop performance and soil properties has been studied extensively under different agro-climatic situations. However, the impact of reversal from conservation tillage to conventional tillage on crop growth and soil nutrient release is rarely addressed. Thus, this study was conducted by converting half of the eight years old conservation tillage experiment to the conventional one with a similar level of residue return to compare the effect on soil nutrient availability and nutrient uptake in soybean crops in the Vertisols of Central India. The conservation tillage treatments included no-tillage (NT) and reduced tillage (RT) with 100% NPK (T1), 100% NPK + farmyard manure (FYM) at 1.0 Mg-carbon (C)/ha (T2), and 100% NPK + FYM at 2.0 Mg-C/ha (T3). After eight years of the experiment, the RT and NT treatments were subjected to conventional tillage, and thus the tillage treatments were RT-CT, RT, NT, and NT-CT. After tillage reversal for three growing seasons, soybean yield and nutrient uptake (N, P, K) got significantly influenced by the tillage and nutrient management. Averaged across nutrient treatments, NT showed highest soil organic carbon (SOC) content (8.4 g/kg) in the surface 0–5 cm layer. However, at 5–15 cm depth, the SOC was greater in the RT-CT treatment by 14% over RT and by 5% in the NT-CT treatment over NT. The soil nutrient availability (N and P) was not significantly (p > 0.05) affected by the interaction effect of tillage and nutrient on the surface soil layer (0–5 cm). Interaction effect of tillage and nutrient was significant on available P content at 5–15 cm soil depth. In contrast to N, soil available P relatively increased with reversal of tillage in both NT and RT. Tillage reversal (NT-CT, RT-CT) and RT had significantly higher available potassium than NT in 0–5 and 5–15 cm soil layers. Among the treatments, NT-CT-T3 showed significantly higher seed N (85.49 kg/ha), P (10.05 kg/ha), and K (24.51 kg/ha) uptake in soybean. The study indicates conventional tillage with residue returns and integrated nutrient management could be a feasible alternative to overcome the limitations of no-till farming in the deep black Vertisols of Central India.

“…Li et al (2007) showed that the available N, P, and K decreased with an increase in the soil bulk density in the deep soil layers, and deep tillage promoted the growth and accumulation of dry matter in maize during the late part of the growth stage. Feng et al (2014) indicated that harrow tillage and rotary tillage could adjust the soil C and N conditions for the winter wheat-summer maize cropping system. In the present study, with respect to cotton growth and development, as the soil replacement plus subsoiling treatment replaced the topsoil from 0 to 20 with the subsoil from 20 to 40 cm, the soil nutrients and microbial activity of the topsoil were poorer, thus delaying the cotton growth during the seedling and square formation stage compared with the growth stages under conventional rotary tillage.…”

Background: Long-term rotary tillage has led to the deterioration of cotton production in northern China. This deterioration is due to the disturbance of topsoil, a dense plough pan at the 20-50 cm depth, and the decreased water storage capacity. A 2-yr field experiment was performed from 2014 to 2015 to explore a feasible soil tillage approach to halting the deterioration. The experiment consisted of four treatments: replacing the topsoil from the 0-15 cm layer with the subsoil from the 15-30 cm layer (T1); replacing the topsoil from the 0-20 cm layer with the subsoil from the 20-40 cm layer and subsoiling at the 40-55 cm layer (T2); replacing the topsoil from the 0-20 cm layer with the subsoil from the 20-40 cm layer and subsoiling at the 40-70 cm layer (T3); and conventional surface rotary tillage within 15 cm as the control (CK). Results: The results indicated that the soil bulk densities at the 20-40 cm layer in T2 were 0.13 g•cm − 3 and 0.15 g•cm − 3 lower than those obtained from CK in 2014 and 2015, respectively. The total nitrogen (N) and the available phosphorus (P) and potassium (K) contents from the 20-40 cm layer in T2 and T3 were significantly higher than those in CK and T1. The amount of soil water stored in the 0-40 cm layer of T2 at the squaring stage of cotton was 15.3 mm and 13.4 mm greater than that in CK in 2014 and 2015, respectively, when the weather was dry. Compared with CK, T2 increased cotton lint yield by 6.1 and 10.2 percentage points in 2014 and 2015, respectively, which was due to the improved roots within the 20-60 cm layer, the greater number of bolls per plant and the higher boll weight in the T2 treatment. Conclusions: The results suggested that soil replacement plus subsoiling would be a good alternative to current practices in order to break through the bottleneck constraining cotton production in northern China. Replacing the topsoil in the 0-20 cm layer with the soil from the 20-40 cm layer plus subsoiling at the 40-55 cm layer would be the most effective method.

“…The winter wheat–summer maize double cropping system is the main cropping pattern in the Huang‐Huai‐Hai region, one of the most important crop production regions in China (Feng et al, ) producing approximately 45% of China's total cereal production (Fang et al, ). However, agricultural water shortages and how to solve these problems have become burning issues in recent years (Brown and Halweil, ).…”

To achieve high‐yielding and eco‐friendly crop production, it is crucial to identify the critical water requirement period of crops, especially in annual crop production systems. A 2‐year experiment was established to study the annual yield, total water consumption and water productivity (WP) of a winter wheat (Triticum aestivum L.) and summer maize (Zea mays L.) system in the Huang‐Huai‐Hai Plain. The results showed that the annual yield of this crop system increased with irrigation frequency and was highest when irrigation was applied three times in the wheat season and once in the maize season (W3M1), though there was no significant difference in annual yield among W2M1, W3M1 and W4M1. And there is no evidence in this paper that irrigation scheduling substantially affects WP. W2M1 had the second highest annual yield (18.7 t ha−1 in 2013–2014 and 19.9 ha−1 in 2014–2015) with a low amount of irrigation compared with W3M1 and W4M1. The highest total water consumption was measured in W3M1 and reached 812 and 873 mm in the first and second years, respectively. Irrigation during the summer maize sowing stage is essential for improving the annual yield and WP. © 2018 John Wiley & Sons, Ltd.
