“…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.

“…Further, this may help in unlocking the locked nutrients in soil organic matter and may be beneficial in improving soil nutrient availability and crop uptake [24][25][26]. Tillage operations reduce soil compaction, improve aeration, and create a better environment for soil microorganisms [27,28].…”

“…This is because crop residue is a significant source of external carbon (C) input, while concurrently impacting native SOC mineralization (Fang et al, 2018). Moreover, crop residue retention and application to soil is an integral component of sustainable and conservation agriculture worldwide (Campbell et al, 2001;Corsi et al, 2012;Lal and Kimble, 1997;Lenka et al, 2015) ) with numerous benefits to soil properties, functioning and processes (Chen et al, 2014;Fang et al, 2018;Sarker et al, 2018;Singh et al, 2014). Directly, residues are the sources of energy and nutrients to the soil microbiome which may consequently affect SOC and residue C mineralization (Shahbaz et al, 2017a).…”

Priming of soil organic carbon (SOC) is a crucial factor in ecosystem carbon balance. Despite its increasing importance in the changing global climate, the extent of influence of temperature and soil properties on the priming effect remains unclear. Here, soil priming was investigated using 13 C labeled wheat residues in two cultivated subtropical soils of Australia (Vertisol and Luvisol) at four incubation temperatures (13, 23, 33 and 43°C). The priming effect was computed from respired CO2 and associated δ 13 C, which were measured periodically over the 52-day incubation period. Wheat residue addition resulted in greater priming effect in the Luvisol (1.17 to 2.37% of SOC) than the Vertisol (0.02 to 1.56 % of SOC). The priming of SOC was the highest at 23°C in the Luvisol, and at 43°C in the Vertsiol, which indicates a variable positive priming effect of temperature in different soil types. Wheat residue addition significantly increased the temperature sensitivity (Q10) of SOC mineralization in the Vertisol at temperature ranges below 33°C (i.e., 13-23 and 23-33°C) and had no significant effect in the Luvisol. A negative correlation was observed between temperature and the Q10 values. Across soils, the Q10 of residue C was lower than SOC suggesting that soil C is more vulnerable to climatic warming. This work demonstrates that the magnitude of SOC priming by wheat residue and Q10 of SOC mineralization varied significantly with soil type (Luvsiol > Vertisol) and incubation conditions (temperature and time). Given the current trend towards increasing atmospheric temperatures, future studies should evaluate temperature effects on the priming of different pools of SOC induced by crop residue in different agro-ecosystems.

“…On the other hand, small macro aggregate associated SOC was significantly higher under reduced tillage than no-tillage. Increase in aggregation concomitant with increases in SOC has been observed in notillage and reduced tillage systems (Paustian et al 2000;Six et al 2000;Lenka and Lal 2013;Lenka et al 2015;Yadav et al, 2020). Further, the influence by tillage on SOC seems to depend on the depth to which the tillage/ploughing operation incorporates plant material.…”

“…The two tillage systems differ with respect to residue management. In no tillage, all the residue retained is found on the soil surface, while in reduced tillage, the residue is incorporated at ploughing depth (Lenka et al, 2015;Lenka and Lenka, 2014;.On the contrary, crop residue remain on the surface in case no-tillage is more vulnerable to different losses like decomposition and erosion. Thus, carbon input to the soil in the initial years of adoption is higher under reduced tillage than no-tillage.…”

Aim: To study the combined effect of tillage and manure addition on bulk soil and aggregate associated carbon and nitrogen in Vertisol. Methodology: The study was conducted in a long-term tillage experiment having two tillage treatments (reduced tillage and no-tillage) together with100% NPK fertilizer without (T1) and with addition of farm yard manure (T2) @ 2.0 ton C ha-1 to soybean in a soybean-wheat cropping system in a Vertisol of Central India, with three replicates in a split plot design. The parameters studied were aggregate size distribution, mean weight diameter, water stable aggregates, bulk soil and aggregate associated organic carbon, available nitrogen and rate of carbon mineralization. Results: The results indicated significantly higher SOC in reduced tillage (0.87%) than no-tillage (0.71%) under100% NPK fertilization in the bulk soil for 0-15 cm depth. However, 100% NPK + FYM showed a significant increase in the bulk soil organic carbon in the no-tillage treatment only. Available nitrogen content in the bulk soil and aggregate fractions were significantly lower under no-tillage than the corresponding reduced tillage treatments. Manure addition led to significantly higher available N content and proportion of WSA in both the tillage practices. The carbon mineralization was significantly higher by 1.4 to 1.6 times under reduced tillage than no-tillage. Interpretation: Long-term tillage study in Vertisol of Central India indicated reduced tillage to be a better option than no-tillage in maintaining organic carbon and nitrogen availability in soil.
