Analysis of Precision Agriculture Datasets for on -Farm Research
"Data collected with ""Precision Agriculture"" (PA) technologies can provide new insights into soil plant relationships and how these relationships are affected by management practices. However, to analyze these datasets requires the consideration of limitations due to differential spatial scaling, …

Soil fertility management and economics of soybean in Ghana
… of the factors influencing the dissemination of agricultural technology and commercialization is fundamental to the design of appropriate strategies to stimulate development, uptake, and scaling. This dissertation examines the economics of soybean with respect to soil fertility management, …

Is Everything Connected? Following the Predators, Pests, and Plants Within a No-Till, Western Montana Agroecosystem
… tillage activities in hopes of retaining populations of beneficial, predatory insects that may decrease the need for pesticide use. The purpose of this research was twofold. First, this on-farm research assessed the population and activity of six beneficial arthropod predators - the carabid beetle …

The critical seed-filling period duration is dependent on soybean planting date and cultivar maturity selection: implications for crop management
… the midwestern United States was not found to contribute to increasing soybean [Glycine max (L.) Merr.] yields. However, decades of genetic improvement concurrent with crop management research has resulted in a clear consensus among midwestern university researchers that soybean yield potential …

Using cover crops to alleviate compaction in organic grain farms
Organic producers rely on mechanical operations for weed management, creating compacted areas that favor weedy species thus forming a cycle of tillage, compaction and increasing weed populations. In an effort to address the concerns of organic grain farmers from Illinois, we explored the effect of …

Learning-based crop management optimization using multi-stream convolutional neural networks
… challenge. Despite the advances in precision agriculture, new methods are needed to create decision-support systems to help farmers increase productivity while accounting for environmental impacts and financial risks. This dissertation presents a class of learning-based optimization …

Forage Yield Variability on New York Dairy Farms
Dairy farms can improve their environmental footprint by feeding more homegrown forage. As a consequence higher yields will reduce feed imports and enhance nutrient use efficiency. To improve forage production, limitations to production need to be identified. While yield records can provide …

Soybean Growth and Yield Response to Seeding Rate in Virginia
… has increased dramatically with the introduction and adoption of herbicide-resistant cultivars, generating interest from growers to reduce seeding rates to the lowest possible level that does not affect yield. Research indicates that greater seeding rates are needed to maximize yield under …
