QUANTIFYING THE SHORT-TERM IMPACTS OF COVER CROPS AND GRAZING ON SOIL HEALTH UNDER AN INTEGRATED CROP-LIVESTOCK SYSTEM IN SOUTH DAKOTA VISHAL SETH 2018 Cover crops and grazing under Integrated Crop-Livestock System (ICLS) can impact the rhizosphere nutrient cycling and may have potential to increase the long-term sustainability and economic profitability of agricultural production system. In South Dakota, crop production practices and livestock husbandry are both common which provide the opportunity for ICLS to be successful in this region. However, little is known about the impacts of the cover crops and grazing under ICLS on soil properties in this region. The present study was conducted at South Dakota State University Research Farm (44°20'34.8"N, 96°48'14.8"W), Brookings, SD, to quantify the impacts of cover crops and grazing on soil bulk density (BD), soil penetration resistance (SPR), soil water retention (SWR), pore size distribution (PSD), total nitrogen (TN), carbon and nitrogen fractions (labile, stable, and inert), microbial biomass carbon/nitrogen, urease and betaglucosidase enzyme activity. Study treatments included grass leaf and broad leaf dominated cover crop mixtures, both with and without grazing, and the cover crop control field with no cover crop or grazing. The experimental site was established on June 2016 by planting of cover crops and soil samples were collected three times i.e., pregrazing, post-grazing and summer phase at 0to 5-cm for bulk density, SPR, SWR and PSD; 5to 15-cm for soil microbial and enzymatic properties.
