“…Therefore, DMPP has the potential to be a good nitrification inhibitor in agricultural management practices. A previous study found that DMPP decreased gross soil autotrophic nitrification rates and reduced gross mineralization rates through feedback regulation (Zhu et al, 2019). DMPP application reduced the risk of nitrate leaching and N losses due to denitrification and did not increase NH 3 volatilization (Zerulla et al, 2001;Li et al, 2008).…”

In order to solve the problems of nitrogen (N) losses and fruit quality degradation caused by excessive N fertilizer application, different dosages of the nitrification inhibitor, 3,4dimethylpyrazole phosphate (DMPP) (0, 0.5, 1, 2, and 4 mg kg −1 soil), were applied during the later stage of 'Red Fuji' apple (Malus domestica Borkh.) fruit expansion in 2017 and 2018. The effects of DMPP on soil N transformation, carbon (C)-N nutrition of tree, and fruit quality were investigated. Results revealed that DMPP decreased the abundance of ammonia-oxidizing bacteria (AOB) amoA gene, increased the retention of NH 4 +-N, and decreased NO 3 −-N concentration and its vertical migration in soil. DMPP reduced 15 N loss rates and increased 15 N residual and recovery rates compared to the control. 13 C and 15 N double isotope labeling results revealed that DMPP reduced the capacity of 15 N absorption and regulation in fruits, decreased 15 N accumulation in fruits and whole plant, and increased the distribution of 13 C from vegetative organs to fruits. DMPP increased fruit anthocyanin and soluble sugar contents, and had no significant effect on fruit yield. The comprehensive analysis revealed that the application of 1 mg DMPP kg −1 soil during the later stage of fruit expansion effectively reduced losses due to N and alleviated quality degradation caused by excessive N fertilizer application.

“…The effectiveness of the nitrification inhibitors can be affected by soil properties such as soil water content (Barrena et al 2017), and soil organic matter and clay content (Zhu et al 2019). Zhu et al (2019) reported that the efficiency of DMPP in reducing nitrification and N 2 O emissions was lower in soils with high organic matter and clay contents, likely due to the high rates of adsorption of DMPP by soil organic matter and clay. The effectiveness of DCD in reducing N 2 O emissions from urine patches in New Zealand is highly season-specific, with reductions of 52, 39 and 16% in autumn, spring and summer, respectively, but DCD application increased NH 3 emissions by 56, 9 and 17% in the respective seasons (Zaman et al 2009).…”

Measuring Emission of Agricultural Greenhouse Gases and Developing Mitigation Options Using Nuclear and Related Techniques

Agricultural lands make up approximately 37% of the global land surface, and agriculture is a significant source of greenhouse gas (GHG) emissions, including carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Those GHGs are responsible for the majority of the anthropogenic global warming effect. Agricultural GHG emissions are associated with agricultural soil management (e.g. tillage), use of both synthetic and organic fertilisers, livestock management, burning of fossil fuel for agricultural operations, and burning of agricultural residues and land use change. When natural ecosystems such as grasslands are converted to agricultural production, 20–40% of the soil organic carbon (SOC) is lost over time, following cultivation. We thus need to develop management practices that can maintain or even increase SOCstorage in and reduce GHG emissions from agricultural ecosystems. We need to design systematic approaches and agricultural strategies that can ensure sustainable food production under predicted climate change scenarios, approaches that are being called climate‐smart agriculture (CSA). Climate‐smart agricultural management practices, including conservation tillage, use of cover crops and biochar application to agricultural fields, and strategic application of synthetic and organic fertilisers have been considered a way to reduce GHG emission from agriculture. Agricultural management practices can be improved to decreasing disturbance to the soil by decreasing the frequency and extent of cultivation as a way to minimise soil C loss and/or to increase soil C storage. Fertiliser nitrogen (N) use efficiency can be improved to reduce fertilizer N application and N loss. Management measures can also be taken to minimise agricultural biomass burning. This chapter reviews the current literature on CSA practices that are available to reduce GHG emissions and increase soil Csequestration and develops a guideline on best management practices to reduce GHG emissions, increase C sequestration, and enhance crop productivity in agricultural production systems.

“…Although DMPP capacity to reduce nitrification rates and N 2 O emissions has been well established [52][53][54], the effects on soil N gross rates (especially ammonification rates) have been poorly investigated as well as the combined effects with natural zeolites in soil. One of the few examples is [55], where a general increase of mineralization of recalcitrant organic N after DMPP addition in two soils was observed, beside a reduction in gross nitrification and N 2 O emissions. DMPP as an organic molecule can decompose and hence provide a source of C for microorganisms that may further stimulate mineralization processes.…”

“…The soil organic C content and amount of clay minerals can also play a role in the performance of DMPP as a consequence of sorption-effects [56]. High sorption of DMPP may result in a lower availability to microorganisms and hence to a lower efficiency; the authors of [55,57,58] evaluated the effects of natural and NH 4 + -charged CHA-zeolite on the sorption of DMPP in soil and concluded that the soil was more efficient in binding DMPP, thanks to the presence of higher levels of organic C that favored the sorption of DMPP. The CHA-zeolite contained in the tuff could not, therefore, retain DMPP by ion exchange processes but instead brought mostly to a reduction in the overall sorption capacity of the soil, due to their lack of organic C. This outcome speculates if this lower sorption capacity in zeolite amended soils also affects the availability of DMPP to soil microbial biomass and consequently the overall efficiency in inhibiting nitrification.…”

Gross Ammonification and Nitrification Rates in Soil Amended with Natural and NH4-Enriched Chabazite Zeolite and Nitrification Inhibitor DMPP

Using zeolite-rich tuffs for improving soil properties and crop N-use efficiency is becoming popular. However, the mechanistic understanding of their influence on soil N-processes is still poor. This paper aims to shed new light on how natural and NH4+-enriched chabazite zeolites alter short-term N-ammonification and nitrification rates with and without the use of nitrification inhibitor (DMPP). We employed the 15N pool dilution technique to determine short-term gross rates of ammonification and nitrification in a silty-clay soil amended with two typologies of chabazite-rich tuff: (1) at natural state and (2) enriched with NH4+-N from an animal slurry. Archaeal and bacterial amoA, nirS and nosZ genes, N2O-N and CO2-C emissions were also evaluated. The results showed modest short-term effects of chabazite at natural state only on nitrate production rates, which was slightly delayed compared to the unamended soil. On the other hand, the addition of NH4+-enriched chabazite stimulated NH4+-N production, N2O-N emissions, but reduced NO3−-N production and abundance of nirS-nosZ genes. DMPP efficiency in reducing nitrification rates was dependent on N addition but not affected by the two typologies of zeolites tested. The outcomes of this study indicated the good compatibility of both natural and NH4+-enriched chabazite zeolite with DMPP. In particular, the application of NH4+-enriched zeolites with DMPP is recommended to mitigate short-term N losses.
