Abstract:: ... The purposes of this study were to improve knowledge of regional vegetation patterns of C₃ and C₄ plants in the North American Great Plains and to use δ¹³C methodology and long-term research sites to determine contributions of small-grain crops to total soil organic carbon (SOC) now present. Archived and recent soil samples were used. Detailed soil sampling was in 1993 at long-term sites near Akro ...

Abstract:: ... Understanding the effects of long-term management practices on soil C and N pools and activities is essential for sustaining soil productivity. The objectives of this study were to evaluate long-term and seasonal changes in soil organic C (SOC), soil microbial biomass C (SMBC) and N (SMBN), and mineralizable C and N in continuous corn (Zea mays L.) under conventional tillage (CT), moldboard (MB), ...

Abstract:: ... The size and turnover rate of the resistant soil organic matter (SOM) fractions were measured by ¹⁴C dating and ¹³C/¹²C measurements. This involved soils archived in 1948, and recent samples, from a series of long-term sites in the North American Great Plains. A reevaluation of C dates obtained in the 1960s expanded the study scope. The ¹⁴C ages of surface soils were modern in some native sites an ...

Subject:: lowland forests; bottomland soils; soil temperature; soil water content; carbon dioxide; losses from soil; clearcutting; felling; biogeochemical cycles; emissions; soil respiration; Texas
Abstract:: ... The effect of forest disturbance on C cycling has become an issue, given concerns about escalating atmospheric C content. We examined the effects of harvest intensity on in situ and laboratory mineral soil respiration in an East Texas bottomland hardwood forest between 6 and 22 mo after harvesting. Treatments included a clearcut, a partial cut wherein approximately 58% of the basal area was remove ...

Abstract:: ... Adoption of conservation tillage in cotton cropping systems lags well behind other major crops in the United States. The Texas High Plains region is the largest cotton-producing region in the United States and is in an area where soil and water conservation are of utmost importance. There is little information of the impacts of conservation tillage on soil function within this environment, and lon ...
