“…As have been reported by previous studies, factors impacting nitriication process including quantity and quality of soil N input, soil moisture (water holding capacity) [34,35], soil temperature [10,17,30], irrigation and tillage practices, soil type, soil oxygen concentration, dissolved organic C availability (controlling substrate availability of soil microbes) [17,36], additives for soil Nitrogen in Agriculture -Updatesamelioration, vegetation or crop types [37], land use change and soil pH [36,38]. While soil N provided substrate for transformation process producing soil N 2 O, other factors regulated N 2 O production process mainly via indirect efects on soil microbial activities.…”

Nitrogen (N) is one of the most important plant nutrient, and its availability and transformations are vital for net primary production. Soil N transformations include mineralization, nitriication and denitriication processes. Nitrogen mineralization transforms organic N into inorganic N, providing available N for crops. Both nitriication and denitriication are microbe-driven processes associated with nitrous oxide (N 2 O) emissions. Nitriication inhibitors have been demonstrated to be useful in decreasing soil N 2 O emissions, including the application of nitriication inhibitors, such as dicyandiamide (DCD) and 3,4-dimethylpyrazole phosphate (DMPP). Recently, biological nitriication inhibitors have also atracted researchers' atention, which may be more environment-friendly. In addition, biochar commonly used as soil ameliorant to improve soil quality and C sequestration could also mitigate soil N 2 O emissions. Once all efective strategies would be widely implemented, more environment-friendly agriculture could be expected.

“…Air-dried soil samples that had been passed through a 2 mm sieve were further ground to pass through a 0.149 mm sieve for the determination of organic C, total N, and total P [16,17]. Soil organic C was determined by the potassium dichromate (H 2 SO 4 -K 2 Cr 2 O 7 ) oxidation method [18,19].…”

Intensive management of C. oleifera has produced many pure C. oleifera plantations. The transmission of C. oleifera plantation will potentially affect soil C, N, and P pools as well as their stoichiometric characteristics both in top soil layer and vertical soil profile due to the intensive management. To understand changes in vertical pools and stoichiometric characteristics of soil C, N, and P as affected by intensive management of C. oleifera plantations, both mixed and pure C. oleifera plantations were studied. We conducted studies in five locations in Jiangxi, China with both pure and mixed C. oleifera plantations, to compare changes in vertical pools and stoichiometry of C, N, and P. Both C and N pools were significantly different between mixed and pure plantation types of C. oleifera.
