Evaluation of Biological Nitrification Inhibition (BNI) Capacity in a Biparental Mapping Population of Brachiaria humidicola
Soil nitrogen (N) loss due to rapid nitrification (oxidation of ammonium to nitrate) is a serious problem with economic and environmental implications. As a result, a large proportion of N fertilisers applied to crops are lost to the environment via nitrate leaching and nitrous oxide emissions. The tropical pasture grass Brachiaria humidicola (Bh) exudes organic molecules from roots that inhibi...
متن کاملEvidence for biological nitrification inhibition in Brachiaria pastures.
Nitrification, a key process in the global nitrogen cycle that generates nitrate through microbial activity, may enhance losses of fertilizer nitrogen by leaching and denitrification. Certain plants can suppress soil-nitrification by releasing inhibitors from roots, a phenomenon termed biological nitrification inhibition (BNI). Here, we report the discovery of an effective nitrification inhibit...
متن کاملNatural Abundance of Foliar 15N as an Early Indicator of Nitrogen Deficiency in Fertilized Cotton
Information on the contribution of various soil nitrogen (N) sources to plant N uptake is often needed for the implementation of sustainable or site-specific management practices in agriculture. Considering the limitations of traditional methods in meeting these needs, this study investigated the potential of leaf δ15N as an early indicator of nutrient deficiency in cotton. The spatial and temp...

ممانعت از نیتریفیکاسیون در اکوسیستم‌های طبیعی چندین دهه است که مطرح می‌باشد. این اثرات ممانعت کنندگی یک ویژگی ژنوتیپ‌های وحشی می‌باشد تا ارقام تجاری. بسیاری از گیاهان مخصوصاً گراس‌ها نشان داده شده اند که دارای این خاصیت ممانعت از نیتریفیکاسیون هستند و اخیراً برخی ژنوتیپ‌های Brachiaria مخصوصاً humidicola Brachiaria توجه زیادی را به سبب نقش آن‌ها در کاهش میزان نیتریفیکاسیون در خاک از طریق ترشحات ریش...
متن کاملPotential for biological nitrification inhibition to reduce nitrification and N2O emissions in pasture crop-livestock systems.
Agriculture and livestock production systems are two major emitters of greenhouse gases. Methane with a GWP (global warming potential) of 21, and nitrous oxide (N2O) with a GWP of 300, are largely emitted from animal production agriculture, where livestock production is based on pasture and feed grains. The principal biological processes involved in N2O emissions are nitrification and denitrifi...
