“…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.

“…Carbon to N ratio (C/N) was calculated based on C and N concentrations. Soil NH 4 + and NO 3 - (AN) were extracted by 2 mol L -1 potassium chloride solution produced by deionized water and determined by the colorimetric method [ 8 ]. Microbial biomass C and MBN were measured by the chloroform fumigation—potassium sulfate extraction method [ 33 , 34 ].…”

Impact of understory vegetation on soil carbon and nitrogen dynamic in aerially seeded Pinus massoniana plantations

Understory vegetation plays a vital role in regulating soil carbon (C) and nitrogen (N) characteristics due to differences in plant functional traits. Different understory vegetation types have been reported following aerial seeding. While aerial seeding is common in areas with serious soil erosion, few studies have been conducted to investigate changes in soil C and N cycling as affected by understory vegetation in aerially seeded plantations. Here, we studied soil C and N characteristics under two naturally formed understory vegetation types (Dicranopteris and graminoid) in aerially seeded Pinus massoniana Lamb plantations. Across the two studied understory vegetation types, soil organic C was significantly correlated with all measured soil N variables, including total N, available N, microbial biomass N and water-soluble organic N, while microbial biomass C was correlated with all measured variables except soil organic C. Dicranopteris and graminoid differed in their effects on soil C and N process. Except water-soluble organic C, all the other C and N variables were higher in soils with graminoids. The higher levels of soil organic C, microbial biomass C, total N, available N, microbial biomass N and water-soluble organic N were consistent with the higher litter and root quality (C/N) of graminoid vegetation compared to Dicranopteris. Changes in soil C and N cycles might be impacted by understory vegetation types via differences in litter or root quality.

Forest land fertilization is a supplement and regulation method based on the regular pattern of forest physiological activity and nutrient demand, combined with the ability of soil to supply nutrient elements. We summarized the important achievements and influential events of forest land fertilization and nutrient management in modern times, and discussed the main problems of forest land fertilization at this stage. The main theories of comprehensive nutrition diagnosis method, formula fertilization method, site nutrient effect fertilization model, and ASI-based balanced fertilization method were analyzed. The main scientific research institutions, main tree species, and main research results of forest fertilization research are described. The development trend of the comprehensive nutrition diagnosis method, the combination of forest fertilization theory and environmental ecology principle, the combination of fertilization and forest oriented cultivation goal, the application of precise fertilization technology in forest land, the development of new forest specific fertilizer, the research of plant nutrition molecular genetics, the research of root state and rhizosphere microecosystem, the application of advanced technology and technology, and the development and application of new nonpollution fertilizer were discussed. It is an important research direction to apply the existing research results to forestry production and improve the quality.
