Cover Cropping: How Sustainability and Economics Can Work Hand in Hand
Get PDFResearch finds that over half of the agricultural lands worldwide have been moderately or severely affected by soil degradation (Kopittke et al., 2019). This problem is further heightened by the fact that many farmers are concerned about the profitability of sustainable practices. As a result, this may lead to an increase in the practice of more harmful conventional agricultural techniques if they continue to be considered more economically beneficial in comparison. This paper aims to see if the use of a specific sustainable practice known as cover cropping can help to increase the level of economic benefits farmers receive. Cover crops are typically planted between growing seasons of desired cash crops to promote and sustain soil health. In general, cover crops have often been found to offer benefits such as increased crop yields and a decreased need for fertilizers through increasing the level of soil nitrogen. Using the USDA Census of Agriculture, data from each county in Pennsylvania will be analyzed to determine if a significant difference in net cash farm income exists between farms that utilize cover crops versus those that do not. The results found will be used to investigate if there is any evidence that encouraging farmers to practice cover cropping in order to sustain soil health can have financial benefits as well
Sex Differences With Voluntary Wheel Running in Mice With a Systemic Deletion of Acetyl CoA Carboxylase 2
No full textFatty acids are an important energy source in long-duration endurance exercise. Mitochondrial uptake of fatty acids can be inhibited by malonyl-CoA, produced by the enzyme Acetyl CoA Carboxylase 2(ACC2). Therefore, ACC2 could be a cellular target to promote fatty acid metabolism and enhance exercise performance. In this study, mice with a systemic deletion of ACC2 (ACC-TKO) and control mice, were confirmed by genotyping before the study began. Male and female mice (n=29 in each group) were randomly assigned to voluntary wheel running or sedentary groups. Mice in the voluntary wheel running group were provided unlimited access to a running wheel in their home cage for six weeks. A data acquisition system connected to the running wheel monitored daily activity. Running wheel activity was recorded at 30-minute intervals during each twenty-four-hour period over the six weeks and reported as total distance, average velocity, and peak velocity. The body weights of the wheel-running mice were assessed weekly. At the end of six weeks, the heart, quadriceps, spleen, and adipose tissue were harvested from each mouse and weighed. Glucose, ketone bodies, cholesterol, and triglycerides were measured in the blood of all mice. In addition, triglyceride content was measured in the quadriceps muscle. The collected data was used to determine: 1) the effects of deletion of ACC2 on physical activity levels; 2) the impact of chronic physical activity in ACC2-TKO mice on body weight and adipose tissue mass; and 3) sex dimorphism with ACC2 deletion and/or physical activity
