Recruiting Farmer Collaborators for 2025 Would you like to better understand and predict the optimum nitrogen fertilizer rate within and across your fields? We’re looking for farmers to participate in
Projects
Using Engineering tools to identify and quantify biotic and abiotic stress in soybean for customable agriculture production
PI – Arti Singh; Co-PI – Baskar Ganapathysubramanian, Soumik Sarkar, Asheesh Singh, Daren Mueller and Greg Tylka The goal of this research is to identify and differentiate biotic stresses under
D3AI: Data driven discoveries for agricultural innovation
Co-PI – Asheesh Singh, Baskar Ganapathysubramanian, Carolyn Lawrence, Senior Personnel – Arti Singh and others Currently, the highest priorities for agriculture production are to sustainably meet the food/feed/fuel/fiber requirements of
Smart phone enabled detection and quantification of multiple stresses in soybean
PI – Arti Singh; Co-PI – Baskar Ganapathysubramanian, Soumik Sarkar, Asheesh Singh, Daren Mueller and Greg Tylka The main objective of the project was to differentiate mutliple stresses in soybean
Quantifying temporal and spatial variability of nitrate-N leaching across iowa
We work to determine what drives the large variability in NO3-N losses from agricultural fields across the state.
Root-water table interactions in corn-soybean systems
In this study we investigate how groundwater table depth may influence plant growth above- and below-ground through affecting the vertical distribution of roots. The purpose of this project is to
Saliency-driven robotic networks for Spatiotemporal plant Phenotyping
PI – Sourabh Bhattacharya; Co-PI – Arti Singh, Soumik Sarkar, Baskar Ganapathysubramanian, Asheesh Singh The objective of this project is to build a network of ground robots that can collect
A multi-scale data assimilation framework for layered sensing and hierarchical control of disease spread in field crops
PI – Soumik Sarkar; Co-PI – Arti Singh, Baskar Ganapathysubramanian, Asheesh Singh and Daren Mueller The availability of cheap, deployable, and connected sensor technology has produced a data deluge at
FACT: A Scalable Cyber Ecosystem for Acquisition, Curation, and Analysis of multispectral UAV image data
A current cyber-agriculture data need is to improve and standardize data collection protocols and to develop curation processes and infrastructure to support the ability of machine learning (ML) to contribute
Biophysical Factors Affecting Nitrous Oxide Fluxes
Soil is the largest terrestrial source of nitrous oxide. In agricultural cropping systems, nitrous oxide typically represents the largest net greenhouse gas flux. Increases in farm efficiency are well known
Nitrogen Use Efficiency
Soil organic matter increases crop yield amount and stability. Soil organic matter – not nitrogen fertilizer – is the largest source of crop nitrogen uptake and environmental nitrogen loss. For
Cover Crops and Nitrogen Retention
Cover crops are an integral component of cropping systems because they grow in the fall and early spring – that is, times when the soil would not have a growing
