Harvesting fertilized rye (Secale cereale L.) cover crop has been suggested as a method to increase producer revenue and biofuel feedstock production, but drainage N loss impacts are currently unknown. Using the tested Root Zone Water Quality Model (RZWQM) across several N rates, spring application of 120 kg N ha-1 prior to winter rye harvest reduced drainage N loss by 54% compared with no cover crop and by 18% compared with planted rye that was neither fertilized nor harvested. Estimates of producer revenue and net energy were also positive, with 8.3 Mg ha-1 of harvested rye biomass. …

2019 Prevent Plant Impacts To South Dakota Grain Crop Value, Matthew Elliott, Lisa Elliott Aug 2019

2019 Prevent Plant Impacts To South Dakota Grain Crop Value, Matthew Elliott, Lisa Elliott

Matthew Elliott

The 2019 crop year has presented various challenges to South Dakota grain crop producers. A record number of prevented planting acres, late planted crops, and trade disputes are expected to significantly lower the value of grain crop production in South Dakota. Preliminary estimates of impact are outlined in the presentation.

Meandering Water In The Prairie Pothole Region Of South Dakota, Matthew Elliott, Lisa Elliott, Tong Wang Aug 2019

Meandering Water In The Prairie Pothole Region Of South Dakota, Matthew Elliott, Lisa Elliott, Tong Wang

Matthew Elliott

This study estimates the agricultural economic impact of the land use changes in the Prairie Pothole Region (PPR) of South Dakota.  The flooding of wetlands has been documented in this region after 1993. At the same time, the conversion of non-cropland to croplands has been observed.  Concerns have been raised if conversions to cropland are conducted on marginal acres that are susceptible to additional flooding.  We found that approximately 140,000 acres of agricultural land have been inundated.  We also found that the new areas of cropland are less prone to flooding than areas that were lost.

Sustainable Agriculture Lesson For Middle School Classrooms, Sara Colombe, Madhav P. Nepal, Jennifer Mclaughlin, Matthew L. Miller, Larry B. Browning, P. Troy White

Madhav Nepal

In this lesson, students will learn about sustainability, where farmers/agriculturists can meet the needs of food, fiber, and fuel for the growing population. Students learn about growing population, its growth rate, major food source, sustainability barrel, potential ripple effects of positive impacts as well as the food waste and its effects.
