Assessing carbon and nitrogen stocks of no-till systems in Oklahoma

Improvement in Soil Physical, Chemical and Microbiological Properties during Cropping Cycles under Different Nutrient Managements in Western Himalayas

“…According to (Kundu et al, 2007), crop rotation is among the best management practices for increasing soil carbon stock. Similar results were obtained in the study done by (Gaiser et al, 2009, Abreu et al, 2011 in which SOC content in soil was increased due to different crop rotations. (Kaur et al, 2008).…”

Nitrogen storage in density and size fractions varied with tillage practices and cropping systems under residue return

“…In this study, the SR of soil TN in MP and NT treatments was 1.13 and 1.70 on average, respectively (Figure 2), which represented that soil quality in NT was better. Although crop residue was returned to the soil in NT and MP, tillage in MP makes residue evenly distributed in the plough layer and accelerates the mineralization of N (Allmaras et al, 2004;Abreu et al, 2011;Zuber et al, 2015). Rossella et al (2007) indicated that the effect of tillage practice on soil TN was mainly related to soil texture, climate and cropping system.…”

What might it cost to increase soil organic carbon using no-till on U.S. cropland?

“…The area of cropland by tillage intensity was derived from data provided by the Conservation Technology Information Center (CTIC) who provided relevant data for tillage intensity by IPCC defined climatic region and crop rotation [ 14 ]. Long term (five consecutive years) NT with adequate moisture is necessary in humid and temperate dry climates for NT cropping systems to increase SOC relative to CT [ 1 , 42 ]. Data for long-term NT adoption provided by the CTIC indicate that, while tillage intensity varies by cropland and climatic region, 1 to 12 percent of U.S. cropland (7.8 Mha total) was under NT in 1997 [ 14 ].…”
