“…This is an important benefit of nitrification inhibitors associated with N fertilizers, since soil acidification by continuous application of N fertilizer is a concern worldwide (Schroder et al, 2011). Although it was not evaluated in our study, the use of nitrification inhibitors has the potential to reduce nitrate leaching (Di et al, 2003) and N 2 O emission (Dai et al, 2013;Shamsuzzaman et al, 2016); nevertheless, it can increase NH 3 emission when mixed to urea-based fertilizers (Soares et al, 2016). In addition, DCD applied to fertilizer can play a role as a sink for methane in tropical humid climate (Jumadi et al, 2008).…”

“…A positive correlation was also observed between N application rates and N-N 2 O emissions [45,51]. Secondly, FYM provides a source of readily available C, which could stimulate nitrifying and denitrifying bacteria and N 2 O production in soils [40,51,52]. The growth of active microorganisms and O 2 consumption in soil pores may result in the formation of a micro-anaerobic environment, favoring denitrification and N-N 2 O production [51].…”

“…Several authors also noticed that a combination of organic and inorganic fertilizers plays a significant role in the improvement of N bioavailability in soils [37][38][39]. The mineral nitrogen concentrations rose considerably under FYM application with an increasing N rate to ≥80 kg N•ha −1 in 0-15 cm and to 120 kg N•ha −1 in 15-60 cm depths [40]. In the present study, the inhibitor addition (NBPT, DMPP, DI) decreased the soil NO 3 -N content compared to the soil with applied FYM (Figure 9).…”

Carbon and nitrogen compounds in agroecosystems have attracted much attention in recent years due to their key roles in crop production and their impacts on environment quality and/or climate change. Since fertilization profoundly disrupted the C and N cycles, several mitigation and/or adaptation strategies, including the application of farmyard manure (FYM) and/or urease and nitrification inhibitors (UI and NI), have been developed. The aim of this study was to evaluate the contents of soil organic carbon and its fractions, the total and mineral forms of nitrogen, as well as CO2 and N2O emissions under mineral and organic fertilization with and without urease and nitrification inhibitors in a maize agroecosystem. A two-year field study was carried out on Cambisols (silt) in Poland. The experiment scheme included nine treatments: C (the control without fertilization), UAN (Urea Ammonium Nitrate), UAN+UI, UAN+NI, UAN+UI+NI, FYM with N mineral fertilizer base, FYM with N mineral fertilizer base+UI, FYM with N mineral fertilizer base+NI, and FYM with N mineral fertilizer base+UI+NI. It was found that treatments fertilized with cattle FYM were higher sinks and sources of C and N compounds in comparison to the UAN plots. The organic carbon, humic and humin acid, and total nitrogen concentrations, in contrast to ammonium and nitrate nitrogen, were not affected by the inhibitors added. Nitrification and urease inhibitors were effective in decreasing N2O emissions only in treatments that were exclusively applied with UAN and had no significant influence on CO2 emissions.

accumulation in shoots than UR-1x. However, in the third cycle, higher shoot N uptake and DM production was recorded in UR-4m than in UR-1x. Furthermore, fertilizer contribution for shoot N uptake in UR-4m plants was higher than those in UR-1x and UR-2m at the end of the experiment. Accordingly, consecutive growing cycles combined with forms of soluble UR application were able to characterize the pattern of N release from coated fertilizers, being, thus, a suitable method to evaluate the efficiency of such products. We argue that our practical approach could be used by the industry in fertilizer quality programs and to register fertilizer coating materials by regulatory agencies.
