“…The highest yield of the NF systems was one sixth of the CF yield. Although NF may not be economically feasible as a regular farming operation, organic farming products could sell at 20-30% higher prices than CF products [32] and the no-till system has advantages of less labor and greater carbon sequestration [33]. To maximize these advantages, we would suggest using a no-till system in a different way.…”

Agricultural fields can store substantial amounts of atmospheric carbon in the soil. In 2011, the Environmentally Friendly Farming Direct Payment Program (EFFDPP) began as a way to promote sustainable agriculture, but the approved methods for receiving the subsidy are limited to the use of manure and cover crops. For evaluating other options for the EFFDPP, we calculated soil carbon inputs and CO 2 emissions in four nature farming (NF) systems for comparisons with conventional farming (CF) and environmentally friendly farming (EF) systems. In 2015, we collected data on farm management from interviews and conducted a field experiment for NF. According to the calculations using a modified Roth C model, the ability for soil carbon sequestration predicted over the next 20 years is the highest in a no-till NF system with grass mulching. CO 2 emission per ha for CF was 4.8 t CO 2 /ha, which was eight times higher than that for NF. However, the highest CO 2 emission per kg of crop was noted in NF with no grass mulching due to very low yield. The total CO 2 emission for CF was similar to that for EF. The NF systems were beneficial in reducing CO 2 emission, but a combination of other approaches is required for satisfying EFFDPP criteria.

Abstract. The average soil temperature was signifi cantly lower in plots covered with hay. Hay mulching, however, did not increase signifi cantly the total number of soil micro-arthropods collected using a soil pin trap and a soil sampler. Signifi cant increases in the number of individuals was recorded only for certain groups. 64% of all the arthropods collected using soil pin traps were collected in hay-covered plots and 36% in control plots. This increase was statistically signifi cant for the orders Entomobryomorpha and Poduromorpha of the subclass Collembola and surface-dwelling (epigeic) Coleoptera. For the samples collected using the soil sampler, 57% of the specimens were collected from hay-covered plots and 43% from control plots. As for the pin traps this was refl ected in differences in the numbers of the orders Entomobrhyomorpha and Poduromorpha of the subclass Collembola and Pauropoda, collected in the treated and control plots. We conclude that mulching affected the different arthropod groups differently.

“…Moreover, soil tillage could also impact soil aeration conditions and indirectly regulate soil N 2 O emissions via efects on microbial activities. Thereby, soil tillage and other disturbance management may be important in impacting soil N 2 O emissions [34,45,46].…”

Nitrogen in Agriculture - Updates

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.
