“…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).…”

“…Conservation agriculture and crop rotation benefit both the environment and soil fertility (Sommer et al 2007); and it has different effects on crop production and nitrogen (N) use efficiency (Limon-Ortega et al, 2004;Kazemeini et al 2014;Pandiaraj et al 2015;Basir et al 2016). Conservation agriculture can increase soil organic matter (SOM), biological activity, macroporosity, stable aggregates, water infiltration, and amount of soil water available to plant, and reduce bulk density (Fabrizzi et al 2005;Wright et al 2005;Liu et al 2014a;Basir et al 2016;Stewart et al 2018;Urra et al 2018). Formerly, Karlen et al (1994) indicated that crop rotation allowed breaking soil pathogen cycles and reduced weed pressure.…”

“…In contrast to the benefits indicated by different authors for residue incorporation, Limon-Ortega et al (2008) observed a decrease in grain yield of 0.2 Mg ha −1 in monocropping wheat when residue was incorporated instead of burning. As for biomass activity, Urra et al (2018) showed increased arylsulphatase, alkaline phosphatase, βglucosidase, and urease activities with corn stover incorporation with respect to its removal from the soil. In a soil managed as a permanent pasture, repeated addition of different plant residues (e.g., faba bean and wheat straw), N availability and microbial biomass N are influenced by residue rate and order (Truong and Marschner 2018).…”

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.

“…Soil organic matter (SOM) is a heterogeneous mixture of organic compounds that vary in their nutrient composition, molecular characteristics, age, and biological stability. Increasing SOM by adding carbon is a beneficial agronomic practice that stimulates microbial communities and enhances soil N and C pools [31]. The youngest compounds are the most biologically active compounds, and the materials with intermediate ages contribute to soil physical characteristics [28].…”

Soil Properties for Predicting Soil Mineral Nitrogen Dynamics Throughout a Wheat Growing Cycle in Calcareous Soils

A better understanding of the capacity of soils to supply nitrogen (N) to wheat can enhance fertilizer recommendations. The aim of this study was to assess the soil mineral N (Nmin) dynamics throughout the wheat growing season in crucial stages for the plant yield and grain protein content (GPC). To this aim, we evaluated the utility of different soil properties analyzed before sowing: (i) commonly used soil physicochemical properties, (ii) potentially mineralizable N or No (aerobic incubation), and (iii) different extraction methods for estimating No. A greenhouse experiment was established using samples from 16 field soils from northern Spain. Wheat N uptake and soil Nmin concentrations were determined at following growing stages (GS): sowing, GS30, GS37, GS60, harvest, post-harvest, and pre-sowing. Pearson’s correlation analysis of the soil properties, aerobic incubations and chemical extractions with the soil Nmin dynamics and N uptake, yield and GPC was performed. In addition, correlations were performed between Nmin and the N uptake, yield, and GPC. The dynamics of soil Nmin throughout the cropping season were variable, and thus, the crop N necessities were variable. The soil Nmin values in the early wheat growth stages were well correlated with the yield, and in the late stages, they were well correlated with GPC. N0 was correlated with the late N uptake and GPC. However, the chemical methods that avoid the long periods required for N0 determinations were not correlated with the N uptake in the late wheat growth stages or GPC. Conversely, clay was positively correlated with the late Nmin values and GPC. Chemical methods were unable to estimate the available soil N in the later stages of the growing cycle. Consequently, as incubation methods are too laborious for their widespread use, further research must be conducted.

Harvesting corn (Zea mays L.) stover for production of biofuels, industrial sugars, bioproducts, and livestock bedding is increasing rapidly, but little is known of the impacts of stover removal on soil-borne greenhouse gas (GHG) emissions. This study evaluated the impacts of removing surface corn stover (0, 25, 50, 75, 100 wt. % removal) on carbon dioxide (CO 2) and nitrous oxide (N 2 O) emissions from a sandy loam soil cropped to monoculture corn using conventional moldboard plow tillage (CT) and no-tillage (NT). Stover removal systematically decreased CO 2 emissions from CT, whereas stover removal had little effect on CO 2 emissions from NT. In particular, the CT 0% stover removal treatment produced 47% greater CO 2 emissions (5.75 Mg CO 2-C ha −1) than the CT 100% removal (3.91 Mg CO 2-C ha −1) treatment. Stover removal increased N 2 O emissions from both tillage treatments, producing up to a 75% increase under CT (2.79 kg N ha −1 at 0% removal; 4.87 kg N ha −1 at 100% removal) and up to a 95% increase under NT (1.75 kg N ha −1 at 0% removal; 3.41 kg N ha −1 at 100% removal). Cumulative nitrate exposure increased in comparable patterns to N 2 O emissions when stover residues were removed. There was a trade-off in GHG emissions resulting from stover removal under CT, whereby increasing stover removal reduced CO 2 emissions but increased N 2 O emissions. In contrast, stover removal did not affect CO 2 emissions under NT but it increased N 2 O emissions especially at the 100% removal rates.
