Extensive research has found that cover cropping can increase the overall health of agricultural systems by scavenging excess nutrients, increasing water infiltration, reducing surface runoff, increasing biodiversity, and building organic matter. Furthermore, cover cropping can help enhance the benefits of other farming practices such as no-till planting, creating synergies that increase farm financial and environmental sustainability. In northern climates, there are significant challenges to establishing cover crops due to the short growing window following corn silage harvest. The authors of this article share their experiences, challenges, and successes of integrating cover crops into northern climates.

Fertilizers, particularly nitrogen, comprise a large part of the carbon footprint of crop production. The industry is exploring and applying innovations toward reducing emissions of greenhouse gases arising from the manufacture and use of fertilizers.

Wheat is the most widely grown grain crop in the world, and the United States is ranked as the fourth major wheat producer after China, India, and Russia. Kansas is the top winter wheat-producing state in the United States and, as such, is nicknamed “The Wheat State.” A significant yield gap has existed in Kansas between potential winter wheat yields and the actual farm level average yield. Due to current conflict in the major wheat-growing region of Ukraine and Russia and recent droughts, record decline in world wheat stocks was expected. To further understand winter wheat’s contribution to the economy, production trends, and relationship with climate variability, data available in the state of Kansas through annual winter wheat yield trials and USDA reports were used to study winter wheat historic trends and relations.

There is world-class government and academic research conducted throughout the Canadian Prairies. To adapt government and academic research to local growing environments, there is a broad network of organizations across Alberta, Saskatchewan, and Manitoba that conduct applied research and demonstrations. This article provides an overview of the provincial networks and highlights one organization from each province to showcase the value of applied research that is being conducted across western Canada.

The sorghum aphid (Melanaphis sorghi), also known as the sugarcane aphid, has become a significant pest in the southern United States since its detection in Texas and Louisiana in 2013, now affecting 25 states and impacting sorghum yields. Management strategies, such as resistant cultivars and insecticide applications, are employed, but further research is needed to optimize these methods and evaluate the combined effects of insecticide application and planting dates on aphid control and sorghum yield. The objective of this study was to evaluate the impact of insecticide applications and planting dates on M. sorghi infestations and grain sorghum yield over three growing seasons in Tifton, GA.

In-season nitrogen applications, when managed effectively, offer a powerful tool for enhancing crop productivity and environmental sustainability. By aligning nutrient availability with crop needs, optimizing application methods, and mitigating potential risks, farmers can achieve better outcomes for both their crops and the environment.

The environmental conditions of the Coastal Plains region of the United States provides livestock producers with unique forage production opportunities that may not be experienced nationwide. While the environmental conditions are favorable for forage production, and longer growing seasons, the rising cost associated with livestock production has producers seeking alternative ways to increase productivity while also reducing external input costs, specifically those associated with feeding livestock.

Regenerative practices, such as no-till and cover crops, are advocated for their positive impacts on soil health and the environment. Nevertheless, there are challenges associated with implementing these practices. The objective of this simulation study was to assess the potential for soil carbon sequestration, soil water storage, and cotton yield response when implementing regenerative practices in the water-limited environment of the Texas Rolling Plains region.
