Research Interests

The biogeochemical cycles are natural pathways by which essential elements such as carbon, nitrogen, hydrogen, phosphorus, and sulfur circulate in the Earth's ecosystems. The agroecosystems can significantly modify biogeochemical cycles causing water and air pollution and global warming. My long-term research goal is to develop agronomic tools and strategies to improve agroecosystems management productively and sustainably. To achieve that, I study crop nutrient dynamics and resource use efficiency of sunlight, water, and nitrogen to integrate them into the cropping system. In rainfed and irrigated cropping systems with limited water, maximizing crop production and economic and environmental viability has been challenging. For example, cropping systems in the west-central Nebraska area are mostly cereal-based with corn, wheat, and sorghum. Soybean and field peas are two legume crops partially established in the area but with comparatively lower acreage than cereals. Also, the use of cover crops, particularly in irrigated fields, is a developing management practice increasingly adopted. Therefore, I am interested in the role of legumes and biological nitrogen fixation in cropping systems and the impact of cover crops on the nutrient dynamics and nutrient management of the cash crop.

Extension Interests

Through extension outreach, I listen to growers, visit farm and industry operations, identify current and emerging issues in cropping systems to bring these issues to a research program, and provide research-based information to growers to help them with their daily agronomic decisions. It is my goal to help growers improve their crop management practices and profitability while maintaining the farm operation environmentally sound. The west-central region in Nebraska demands research-based information on legume crops such as soybean and field peas, the use of cover crops, and nutrient management.
