“…Effects of the previous crop on grain yield have been described by other authors (Govaerts et al 2005;Hirzel et al 2011;Pandiaraj et al 2015). These effects can be associated with differences in residue nutritional contribution of previous crops or to the effect of residue composition on soil biomass, which can stimulate increased activity of beneficial soil microorganisms with positive effects on the productivity of the next crop (Kumar et al 2018;Urra et al 2018;Zhang Li et al 2018).…”

“…The positive effect of the bean crop on yield, sedimentation value, and concentrations of some grain and residue nutrients in the wheat crop can be associated with higher N contribution of a legume compared with a non-legume crop (Pandiaraj et al 2015). It can also be the effect of residue incorporation with a low C:N ratio on soil biomass activity and SOM mineralization with contributions from nutrients and compounds that stimulate development and higher crop productivity (Kumar et al 2018;Thuy et al, 2006;Urra et al 2018;Zhang Li et al 2018).…”

“…Pandiaraj et al (2015) also demonstrated that wheat (Triticum aestivum L.) grain yield was higher after green gram (Vigna radiate [L.] Wilczek) compared with corn (Zea mays L.) used as a previous crop; this is associated with the fact that mineral N in the root-zone soil is often higher in a cereal-legume cropping system than in cereal monoculture. Kumar et al (2018) indicated that different crop rotations generate changes in soil C mineralization, and the application of mineral fertilizers associated with crop residues had a positive effect on C and N mineralization and their kinetics. Besides, a permanent surface residue layer provides a barrier against rapid water runoff (Sommer et al 2007).…”

Conservation agriculture using crop rotation benefits the environment, soil fertility, and crop production. A biannual rotation experiment during a period of 2 years was conducted in volcanic soil in south-central Chile in a production system under conservation agriculture. The experiment considered two previous crops, canola (Brassica napus L.) and bean (Phaseolus vulgaris L.), and four levels of residue incorporation (0%, 50%, 100%, and 200% of generated residue). Grain yield (0.41 Mg ha −1 ), grain sedimentation value (5.5%), grain K (0.031%) and Ca (0.006%) concentrations, and residue K concentration (0.159%) were higher when the previous crop was bean. The Ca concentration (0.037%) in wheat residue increased after the canola crop. The different applied residue levels of the previous crop had no effect on any of the evaluated parameters in wheat. There was a very consistent negative correlation between the grain S concentration and the residue P (− 0.55), K (− 0.55), Mg (− 0.61), and S (− 0.63) concentrations in wheat when it was cultivated after bean. A larger number of study cycles are required to obtain more consistent results about the effect of the different residue levels on these two biannual rotations.

“…The CO 2 emission in both 0 -20 cm and 20 -40 cm soil profiles was higher in grassland than other LUMS. The faster release of CO 2 in the early days of incubation implies a rapid depletion of an easily mineralizable carbon fraction, leaving a more resistant fraction of SOC [46] [47] [48].Carbon mineralization is influenced by different cropping systems[49] or LUMS. Higher CO 2 release in grassland samples could be ascribed to high organic matter content, in agreement with[50] who reported higher CO 2 emissions under grassland than afforested land.…”

“…Open Journal of Soil Science had also been reported in grasslands than other land uses[51] [52]. High rates of soil respiration can be attributed to a large pool of labile carbon substrates or rapid oxidation of a smaller pool[53] [52][49]. Hence, a high basal respiration may be a pointer to ecological stress and degradation or high level of ecosystem productivity.…”

Soil organic carbon (SOC) mineralization was carried out on soil samples collected from two depths: 0-20 cm and 20-40 cm for all land use (LU) types (grasslands, croplands, natural forest/fallow lands, cocoa/palm plantations, and settlement/agro-forests). Microbiological analyses were carried out by measuring microbial activity in 40 g of dried soil samples wetted to 60% water holding capacity and incubated at 27˚C. Carbon dioxide (CO 2) emission was measured for 10 weeks using a CO 2 trap. Descriptive and graphical analyses of CO 2 respiration were done using CO 2 emission data. Models were developed to describe CO 2 respiration and the first order kinetic model provided best fit to C-mineralization. Potentially mineralizable carbon (C o) and C-mineralization rate were higher in grasslands than other LU types, indicating a higher rate of microbial activity and carbon cycling. Metabolic quotient was higher in forest/fallow lands and reflects greater stress of the microbial community and a high requirement of maintenance energy. Grasslands enhanced more SOC accumulation and decomposition, suggesting a better carbon sink than other land use and management systems (LUMS). Microbial biomass carbon (MBC) and microbial biomass nitrogen (MBN) varied across LU patterns with maximum values in grasslands and minimum values in natural forest/fallow lands insinuating better soil quality for grasslands. MBC and SOC positively correlated with C o and C-mineralization, which intimates that C-mineralization is influenced by availability of MBC and SOC. Metabolic quotient (qCO 2) negatively correlated with microbial quotient (MBC:SOC), depicting that higher values of qCO 2 signify difficulties in using organic substrates during microbial activity as a result of low MBC:SOC.

Long‐term manure application enhances organic carbon and nitrogen stocks in Mollisol subsoil

Subsoils contain half of the total soil organic carbon (SOC) that is supposed to be relatively more persistent than that present in the topsoil. Improving SOC and total nitrogen (TN) stocks in croplands is crucial to mitigate climate change and ensuring food security. However, our insight into how the management practices and climatic variables influence stocks of SOC and TN, and crop grain yields in the soil profile is limited. In this study, we assessed the long-term impacts of mineral and manure fertilizers on SOC and TN stocks at soil profile levels (up to 100 cm), and cropping system (wheat-maize-soybean) grain yields. Results indicated that in the top 0-40-cm layers SOC and TN stocks were the highest in manure plus mineral fertilizers (MNPK) compared with control, that is, non-fertilized control (CK). Conversely, compared with NPK, sole application of manure (M) clearly increased SOC stocks by 19%, 40%, and 39% and TN stocks by 51%, 105%, and 116% in 40-60, 60-80, and 80-100 cm, respectively (p < 0.05). Moreover, Pearson correlation revealed that climate variables, that is, mean annual temperature (MAT) affected both SOC and TN stocks in 0-40-cm layers only of the soil profile. Our findings implicated that the sole application of manure (M) is vital to augment SOC and TN sequestration, particularly in the subsurface layers. However, trade-offs between SOC and TN sequestration and crop yields should also need to be considered while making recommendations for
