Lakesh K. Sharma CV (PDF)
BS from Guru Nanak Dev University, MS from Punjab Agricultural University, and Ph.D. from North Dakota State University, Fargo, ND. As Post-Doctoral Fellow, I worked for more than a year at North Dakota State University and completed Ph.D. in 2014 with thesis entitled as “Evaluation of Active Optical Ground-Based Sensors to Detect Early Nitrogen Deficiencies in Corn.” Five years of Extension training with Extension Soil Specialist Dave Franzen.
In my career, I have provided educational programs on sustainable agricultural practices to growers, extension agents, crop consultants, industry professionals, and public. Educational materials have been presented using meetings, field tours, extension bulletins, radio, TV, and internet resources.
I am currently teaching agriculture at University of Maine, Presque Isle (UMPI) to train students to solve for future agriculture problems. As a Professor at UMPI, I plan to develop a strong soil and plant science curriculum, teach certificate agriculture courses, and provide tours at research facilities.
Site Specific Farming
My experiences are in soil fertility issues, soil tillage study, slow release nitrogen fertilizers, ground-based active optical sensor for in-season nitrogen recommendations, site specific farming, and economic-based pre-planting fertilizer recommendations for dryland agriculture.
Site specific detection of residual nitrogen and other nutrient levels in soils has been studied successfully in many countries. Zone and grid soil sampling is quite a famous approach to judge the nutrient variations in the soil. In Maine under dryland potato production, zone or grid soils sampling would be a better choice depending upon the target nutrient. In the United States, results have supported growers adopting zone or grid soils sampling easily; and as a result, this sampling will help growers to increase their net profits. Using site specific nutrient detection approach, growers, local businesses, and their associated crop consultants can map the soils and better manage nutrients. (More)
Nutrient study such as N, P, and K requirement in potato, wheat, corn, sunflowers, sugarbeets, and barley; also an issue with soybean fertility such as iron chlorosis. I plan to develop sustainable agriculture systems, site-specific farming system with multiple cropping systems, crop models for economical fertilizer recommendations for growers, sensor-based, in- season nitrogen recommendations, and minimum tillage potato cultivation.
There is a strong need to develop economic-based nutrient recommendation in Maine with emphasis of sustainable environmental practices. The use of appropriate fertilizer, a minimum tillage program, the development of in-season nutrient application rates, and selection of appropriate rotational crops are on top of my agenda. (More)
