Analyzing the Use of Publicly Available Multispectral Imagery to Guide the Creation of Soil Sampling Schemes

Oldag, Jordan (2020-02-26)

As site-specific nutrient management has grown in popularity, the need for accurate soil fertility data has increased. Unfortunately, the cost of detailed soil sampling has prohibited many farmers and consultants from ...

Corn Sustainability for Cellulosic Biofuel and Grain Production in the Southeastern US

Mourtzinis, Spyridon (2013-04-22)

Biofuel production from plant biomass has been proposed as a solution to mitigate fossil fuel use. Corn (Zea mays L.) is an important crop in the Southeast. Its abundance and high yield potential makes it attractive as ...

Data-Driven Agroclimate Modeling and Forecasting Based on Earth Observations and Predictions: A Study of Evapotranspiration, Precipitation, and Crop Yields

Medina, Hanoi (2020-04-17)

Meeting the growing food demand in a sustainable manner is the main challenge faced by agriculture, at a time when the climate changes increasingly threaten food security. Innovative agro-climate approaches are needed to ...

Different Approaches for Improvement of Nitrogen Management in Alabama Corn Grain Production

Torino Isasmendi, Miguel Severo (2013-07-19)

Nitrogen (N) fertilization management in corn (Zea mays L.) production requires more consideration in Alabama. This is due to high spatial variability in soil texture across the state and within fields, and to the high ...

An Economic Evaluation of Variable Rate Irrigation for Alabama Corn and Soybean Production

Whatley, Hunter (2022-11-29)

The variable rate application of production inputs is a method used by row crop producers to save money and resources. However, this technology comes at a substantial investment cost. This includes the capital investment ...

Evaluating Soil-Weather-Agronomic Practices Interactions on Aflatoxin Corn Contamination in the South

Damianidis, Damianos (2016-12-09)

Aflatoxins are potent carcinogens and contaminated corn grains if consumed can have a deleterious effect on both humans and animals. Pre-harvest aflatoxin contamination in corn (Zea mays L.) is a continuing concern in the ...

Evaluation of Deficit Irrigation Strategies and Management Zones Delineation for Corn Production in Alabama

Morata, Guilherme (2020-07-14)

The adoption of center pivot irrigation in Alabama has increased in recent years. The reason is that farmers are achieving high crop yield by avoiding crop water stress. Although, irrigation adoption has increased, Alabama ...

Evaluation of Irrigation Scheduling and Sustainability Indicators as Tools to Increase the Adoption of Conservation Practices Among Central Alabama Farmers

Duarte de Val, Marina (2023-11-27)

In recent years, there has been a significant surge in the adoption of conservation practices in agriculture, driven by a collective understanding of the urgent need to minimize risks, enhance profitability, and protect ...

Evaluation of Irrigation Scheduling Methods and Nitrogen Fertilization Effect on Corn Production in Alabama

Da Cunha Leme Filho, Jose (2016-08-24)

The unpredictable rainfall distribution patterns and high spatial variability in soil texture are promoting changes in irrigation and fertilization management. Irrigation systems are helping farmers to achieve consistent ...

The Impact of Climate Variability on Wheat Growth and Yield

Tapley, Mathew (2012-08-07)

Understanding the environmental factors impacting wheat (Triticum aestivum L.) yield may lead to opportunities to increase yield potential. Variability in climatic conditions during the wheat growing season in the southeastern ...

Influence of climate variability on the ecologically sustainable water withdrawals from streams for irrigation

Sangha, Laljeet (2019-07-10)

Alabama (AL) receives a large amount (1270-1727 mm annual average) of rainfall annually. However, much of the rainfall occurs in the non-crop growing season (winter months), and recurring, severe droughts during the crop ...

Studies on Wheat Scab in Alabama

Subedi, Arjun (2013-07-09)

Wheat scab is one of the more destructive diseases of wheat in the US. In Alabama, scab was not considered a problem in the past; however, during recent years it has been reported in north Alabama. The overall goal of this ...

A study for understanding climate-induced crop production risk and relevant climate hazards in a changing environment

Schillerberg, Tayler (2024-05-15) ETD File Embargoed

Climate change poses significant challenges to global agriculture by influencing crop production through various climatic factors such as precipitation, temperature, solar radiation, and atmospheric gases. These factors ...

Two Alabama Case Studies for Remote Sensing of Water Resources

Shakya, Samriddhi (2015-05-11)

Managing water resources is one of the main challenges for water resource managers. This thesis uses geospatial technologies to assist in monitoring water resources through two case studies that are of concern to both state ...
