Precision Water Management

About the Precision Water Management Lab

Security and sustainable development of our water resources and food production, while minimizing the negative impact on the environment are the grand challenges globally. The contamination of ground and surface waterways due to agricultural nitrate leaching and runoff further complicates water quantity vs. quality dynamics vs. crop productivity and interrelationships. The study area of precision water management holds enormous potential in terms of quality research to address several water quality and quantity issues.  

The precision Water Management lab is designed to address these challenges by developing and adopting precision agricultural water and nutrient management technologies and strategies. Specific objectives include: 

  1. Measurement and modeling of Integrated irrigation and nutrient strategies to enhance/improve water-nutrient use efficiency,  
  2. Reduce agricultural water use, measuring and modeling crop evapotranspiration. 
  3. Reduce the impacts of agricultural management practices on downstream resources, users and water quality. 
  4. Impact of climatic variability/change on crop water productivity. 
  5. Application of Remote Sensing and Geographical Information Systems (GIS) for greater understanding and decision making in agricultural sustainability and water resources.

Presentation Excellence Award, ASABE Annual International Meeting, California | July 2024: Awarded for the oral presentation on "Optimizing Nitrogen Management in Corn Cultivation using DSSAT and Machine Learning Tools to Enhance Yield and Environmental Sustainability | Singh, R. K., & Sharma, V." in the session on New Methods in AI and Machine Learning for Agriculture. Recognized in the top 15% for excellence in content and delivery.

Varshitha got Second prize for Graduate student Poster competition at FLASABE 2024 – held on June 13th, 2024, at Jensen Beach, FL

Title of the poster: Analyzing Potato Response to Different Irrigation and Nitrogen Applications in Suwannee Valley Using Substor- Potato Model

Brief description: This poster evaluates the DSSAT-SUBSTOR model's effectiveness in simulating potato growth parameters, biomass, leaching, and tuber yield under various irrigation and nitrogen application regimes. Preliminary results indicate that while DSSAT accurately predicts growth parameters and yield, it tends to underestimate yields at lower nitrogen levels compared to observed data.
