Determining soil water evaporation and subsurface evaporation zones
Evaporation from the soil largely determines water availability in terrestrial ecosystems and the partitioning of solar radiation between sensible and latent heat. It is key to hydrology and climate. The
Colloid-Mediated Transport of Hormones with Land-Applied Manure
Endocrine-disrupting hormones may enter the environment via land application of livestock manure. With respect to both livestock production and soils, Iowa is the prototype for agriculture in the Midwest. Our
Comparison of Biofuel Systems (COBS)
This project seeks to identify and develop cropping systems that produce large quantities of biofuel feedstocks while protecting soil and water resources and increasing biodiversity on the Iowa landscape. Treatments
Development and Evaluation of Improved Strategies for Genomic Selection Via Simulations and Empirical Testing
The overall goal of the proposed project is to increase the efficiency of crop breeding programs by developing and deploying improved genomic selection strategies that rely on improvements in the
Low-cost nitrate sensors to populate genotype-informed yield prediction models for next generation breeders
Our civilization depends on continuously increasing levels of agricultural productivity, which itself depends on (among other things) the interplay of crop varieties and the environments in which these varieties are
Genetic networks regulating structure and function of the maize shoot apical meristem
The shoot apical meristem (SAM) is responsible for development of all above ground organs in the plant. SAM structure and function correlates with agronomically-important adult traits in the maize plant,
Hierarchical Modeling and Parallelized Bayesian Inference for the Analysis of RNAseq Data
This proposal focuses on the development of hierarchical models and parallelized Bayesian inference for the analysis of RNA sequencing (RNAseq) data. Special emphasis is placed on gene expression profiling of
NRT-DESE: P3 – Predictive Phenomics of Plants
NRT- DESE: Predictive Phenomics of Plants (P3) New methods to increase crop productivity are required to meet anticipated demands for food, feed, fiber, and fuel. Using modern sensors and data
Parallel Algorithms and Software for High-Throughput Sequence Assembly
High-throughput next-generation DNA sequencing technologies (NGS) are causing a major revolution in life sciences research by allowing rapid and cost-effective sampling of genomes and transcriptomes (expressed genomic sequences). Assembly of
“Transgenic Approaches In Managing Sudden Death Syndrome In Soybean”
Our long-term goal is to create soybean cultivars resistant to soybean sudden death syndrome (SDS). Soybean is one of the world’s most valuable crops and the U.S. is the world
Sorghum breeding program for biofuel production
Biofuels are a major contributor to the energy security of the United States, to the economic growth of Iowa and to the reduction of greenhouse gasses emission. The Energy Independence
