1. Effects of Residue Placement on Co2 Loss in an Irrigated, No-till Corn SystemIt is well known that residue management practices that leave crop residue on the surface, such as no-till agriculture, promote soil fertility. However, the effects of such practices on carbon sequestration can be highly variable. To better understand how residue management impacts the loss of carbon through mineralization, we investigated the effects of residue location and addition on CO2 produced from residue decomposition under no-till irrigated continuous corn in Northern Colorado. Over... H. Oleszak, F. Cotrufo, S. Leichty, C. Stewart |
2. Soil Analysis Methods Accuracy and Precision Comparison: Historical North American Proficiency Testing (NAPT) Program ResultsThe SSSA-NAPT Program provides open access to soil, water, and plant laboratory data. This data is collected quarterly from about 150 participating laboratories. For soil data, five samples are sent to participant laboratories for them to submit data for any or all of the 99 accepted methods. Our objective was to evaluate data precision from 43 soil samples (2019-2021). A measure of precision was made by dividing the Median Absolute Deviation (MAD) by the Median for each of the 43 samples... B.G. Hopkins, G.E. Cardon, J.R. Lawley |
3. Cover Crop Termination Timing Effects on Soil and Cotton Nutrient AvailabilityCover crop termination timings can have large impacts on the amount of soil coverage, nutrient availability, and stored soil moisture in a system. Producers in semi-arid regions must gamble the possibility of increased soil infiltration and reduced soil water evaporation against the potential of decreased soil moisture; in the SHP, success is dependent on irrigation capacity and precipitation. Optimizing termination timings for semi-arid regions and in deficit-irrigation/dryland systems is critical... C. Cobos, G. Baath, J. Burke, S. Chatterjee, P. Delaune, K. Lewis |
4. Sustainable and Resilient Cropping Systems to Mitigate Wind Erosion for the Enhancement of Human HealthIn the Texas High Plains, regenerative cropping practices in a predominantly conventional farming area can be used to prevent further depletion of topsoil by wind erosion. This loss of topsoil can cause a decrease in agricultural productivity and form dust storms that can be detrimental to human health causing a rise in hospitalizations of chronic lung damage, cardiovascular disorders, and diseases contracted by inhalation. Using regenerative farming practices, both the number and size of dust... K. Lewis, R. Babcock, J. Burke, C. Cobos |
