“…Moreover, the type of fertilizer leads to the changes in the behavior of soil enzymes, thereby critically influencing the soil nutrient cycling and in-site fertility [13]. In the literature, the addition of inorganic fertilizers reduced soil nutrient availability and enzyme activity in a cycle of organic matter mineralization [65][66][67]. In this study, however, the individual fatty acid biomarkers did not show any distinguished pattern of soil enzyme activity as discussed previously.…”

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertilizers, were considered. The activities of soil enzymes including dehydrogenase, β-glucosidase, arylsulfatase, urease, alkaline and acid phosphatases were used as indicators of important microbial mediated functions and the soil chemical properties were measured in the soils applied with organic or inorganic fertilizer for 10 years. Fatty acid methyl ester analysis was applied to determine the soil microbial community composition. Relatively higher microbial community richness and enzyme activities were found in the organic fertilizers applied soils as compared to the inorganic fertilizers applied soils. Principal component analysis explained the positive influence of organic fertilizers on the microbial community. The application of organic fertilizers can be a better alternative compared to inorganic fertilizers for the long-term health and security of urban agriculture.

“…Global climate change and hunger have become crucial issues in current years. The main concern of agricultural scientists is to reduce greenhouse gas (GHG) emissions and increase agronomical fertility by increasing soil organic matter and developing soil quality (Agegnehu et al, 2016;Mandal et al, 2016;Yoo et al, 2016;Zhang et al, 2016). The largest part of solar energy radiated back into space and the anthropogenic GHGs adsorb and cause global warming (Kweku et al, 2017).…”

Reducing greenhouse gas emissions and increasing agronomic productivity by sustaining soil organic matter and refining soil fertility have become the main concerns for agricultural scientists. There is a new approach to decrease greenhouse gas emissions, soil C sinks, and improve soil quality using biochar. Soil acidification is improved by applying lime or other acid-neutralizing materials. Additionally, Ca and Mg can increase by applying lime. The availability of Ca, Mg, and K in the soil is significantly affected by the application rate of biochar spread separately or combined with chemical fertilizers. Soil nutrients and maize (Zea mays L.) yield are highly influenced by the use of lime and biochar. Biochar can improve the ecosystem by reducing soil CO2 emissions from agricultural practices. The inconsistent results and clarifications from various studies highlight the importance of relating the impact of different biochar rates on CO2 emissions and maize yield. This review summarizes the properties of biochar, provides the scientific reference for its application to achieve high and good quality maize and reduce CO2 emissions.

“…However, studies reported mixed results for the impacts of adapting no-tillage on N 2 O emissions from 3906 F. Lutz et al: Soil moisture representation for simulating tillage effects on N 2 O emissions in LPJmL5.0-tillage croplands (Deng et al, 2016;Venterea et al, 2011). For instance, no-tillage was found to increase N 2 O emissions (Mei et al, 2018;Van Kessel et al, 2013), decrease N 2 O emissions (Deng et al, 2016;Plaza-Bonilla et al, 2018;Yoo et al, 2016) or have no significant effects (Alvarez et al, 2012;Boeckx et al, 2011) in comparison to conventional tillage systems.…”

The importance of management information and soil moisture representation for simulating tillage effects on N<sub>2</sub>O emissions in LPJmL5.0-tillage

Abstract. No-tillage is often suggested as a strategy to reduce greenhouse gas emissions. Modeling tillage effects on nitrous oxide (N2O) emissions is challenging and subject to great uncertainties as the processes producing the emissions are complex and strongly nonlinear. Previous findings have shown deviations between the LPJmL5.0-tillage model (LPJmL: Lund–Potsdam–Jena managed Land) and results from meta-analysis on global estimates of tillage effects on N2O emissions. Here we tested LPJmL5.0-tillage at four different experimental sites across Europe and the USA to verify whether deviations in N2O emissions under different tillage regimes result from a lack of detailed information on agricultural management, the representation of soil water dynamics or both. Model results were compared to observational data and outputs from field-scale DayCent model simulations. DayCent has been successfully applied for the simulation of N2O emissions and provides a richer database for comparison than noncontinuous measurements at experimental sites. We found that adding information on agricultural management improved the simulation of tillage effects on N2O emissions in LPJmL. We also found that LPJmL overestimated N2O emissions and the effects of no-tillage on N2O emissions, whereas DayCent tended to underestimate the emissions of no-tillage treatments. LPJmL showed a general bias to overestimate soil moisture content. Modifications of hydraulic properties in LPJmL in order to match properties assumed in DayCent, as well as of the parameters related to residue cover, improved the overall simulation of soil water and N2O emissions simulated under tillage and no-tillage separately. However, the effects of no-tillage (shifting from tillage to no-tillage) did not improve. Advancing the current state of information on agricultural management and improvements in soil moisture highlights the potential to improve LPJmL5.0-tillage and global estimates of tillage effects on N2O emissions.
