Memories Of Life On The Farm: Through The Lens Of Pioneer Photographer J. C. Allen, Frederick Whitford, Neal Harmeyer 2019 Purdue University

Memories Of Life On The Farm: Through The Lens Of Pioneer Photographer J. C. Allen, Frederick Whitford, Neal Harmeyer

Purdue University Press Book Previews

John Calvin Allen, professionally known as J. C., worked as a photographer for Purdue University from 1909-1952, and operated his own photography business until his death in 1976. The J. C. Allen photographs represent an historical account of the transition from pioneer practices to scientific methodologies in agriculture and rural communities. During this major transitional period for agriculture, tractors replaced horses, hybrid corn supplanted open-pollinated corn, and soybeans changed from a novelty crop to regular rotation on most farms. During this time, purebred animals with better genetic pedigrees replaced run-of-the-mill livestock, and systematic disease prevention in cattle, swine, and poultry ...

Nitrogen (N) fertilizer recommendation tools could be improved for estimating corn (Zea mays L.) N needs by incorporating site-specific soil and weather information. However, an evaluation of analytical methods is needed to determine the success of incorporating this information. The objectives of this research were to evaluate statistical and machine learning (ML) algorithms for utilizing soil and weather information for improving corn N recommendation tools. Eight algorithms [stepwise, ridge regression, least absolute shrinkage and selection operator (Lasso), elastic net regression, principal component regression (PCR), partial least squares regression (PLSR), decision tree, and random forest] were evaluated using a dataset containing ...

Modeling Experiments For Evaluating The Effects Of Trees, Increasing Temperature, And Soil Texture On Carbon Stocks In Agroforestry Systems In Kerala, India, Ann E. Russell, B. Mohan Kumar 2019 Iowa State University

Modeling Experiments For Evaluating The Effects Of Trees, Increasing Temperature, And Soil Texture On Carbon Stocks In Agroforestry Systems In Kerala, India, Ann E. Russell, B. Mohan Kumar

Natural Resource Ecology and Management Conference Papers, Posters and Presentations

Research Highlights: Agroforestry systems in the humid tropics have the potential for high rates of production and large accumulations of carbon in plant biomass and soils and, thus, may play an important role in the global C cycle. Multiple factors can influence C sequestration, making it difficult to discern the effect of a single factor. We used a modeling approach to evaluate the relative effects of individual factors on C stocks in three agricultural systems in Kerala, India. Background and Objectives: Factors such as plant growth form, management, climate warming, and soil texture can drive differences in C storage among ...


An Improved Thermo-Tdr Technique For Monitoring Soil Thermal Properties, Water Content, Bulk Density, And Porosity, Wei Ping, Yili Lu, Xiaoting Xie, Tusheng Ren, Robert Horton 2019 China Agricultural University

An Improved Thermo-Tdr Technique For Monitoring Soil Thermal Properties, Water Content, Bulk Density, And Porosity, Wei Ping, Yili Lu, Xiaoting Xie, Tusheng Ren, Robert Horton

Robert Horton

The thermo-time domain reflectometry (thermo-TDR) technique is valuable for monitoring in situ soil water content (θ), thermal properties, bulk density (ρb), porosity (n), and air-filled porosity (na) in the vadose zone. However, the previous thermo-TDR sensor has several weaknesses, including limited precision of TDR waveforms due to the short probe length, small measurement volume, and thermal property estimation errors resulting from finite probe properties not accounted for by the heat pulse method. We have developed a new thermo-TDR sensor design for monitoring θ, thermal properties, ρb, n, and na. The new sensor has a robust heater ...


The Farmers' Millennium: The Ideology Of Agricultural Improvement In Iowa, 1855 To 1865, Michael Belding III 2019 Iowa State University

The Farmers' Millennium: The Ideology Of Agricultural Improvement In Iowa, 1855 To 1865, Michael Belding Iii

Michael Belding III

The Morrill Act of 1862, a piece of federal legislation enacted a century and a half ago, lives on today. That law allocated thousands of acres of federal land to state governments, based on the size of their congressional delegations, so they could establish colleges of agriculture and the mechanic arts and give a college education, liberal and practical, to students who could not otherwise afford one. The Morrill Act lives on because the "land-grant colleges" it endowed with financial resources still exist today, operating on billion-dollar budgets and enrolling tens of thousands of students. Further, at least at Iowa ...

This commentary is a comprehensive synthesis of ideas generated from a workshop, hosted by Iowa State University, encompassing precision livestock farming (PLF) research and applications for industry–academia. The goal of this workshop was to demonstrate existing institution research and strategically propel further PLF development and industry adoption. Six key thematic areas were identified from participant discussion: sensors and algorithms, implementation, economic feasibility, data, rural and societal impacts, and education and training. These themes were used to focus discussion on identifying the new knowledge needed to drive implementation and examine current and future challenges of implementing PLF. At the convergence ...

Agricultural and Biosystems Engineering Publications

Studies have shown that biochar has the potential to remove organic and inorganic contaminants from wastewater. pH is known to have a crucial role in the transformation of pollutants. In this research, we explore the feasibility of using biochars properties to control the pH near the water–air interface, so the gaseous emissions from water (or wastewater) could be mitigated. This study aimed to test the effects of a thin layer biochar addition on the spatial and temporal variation of water pH. Two types of biochar and water were tested. Highly alkaline porous (HAP; pH 9.2) biochars made of ...

In 2017, the University of Nebraska-Lincoln Institute of Agricultural and Natural Resources (IANR) and Nebraska Extension made a commitment to implement a multidisciplinary Beef Systems Initiative (BSI). The BSI is administered by the Center for Grassland Studies and is comprised of six projects designed to develop and support the implementation of beef production systems that optimize feed resource use, natural resource conservation, and producer success in Nebraska through improved management of perennial grasslands and systems of integrated crop-beef cattle production. In addition to the BSI, a parallel project funded by the Foundation for Food and Agriculture Research (FFAR) is studying ...

Characterizing The Soil Microbiome And Quantifying Antibiotic Resistance Gene Dynamics In Agricultural Soil Following Swine Cafo Manure Application, Edward Lopatto, Jinlyung Choi, Alfredo Colina, Lanying Ma, Adina Howe, Shannon Hinsa-Leasure

As agriculture industrializes, concentrated animal feeding operations (CAFOs) are becoming more common. Feces from CAFOs is often used as fertilizer on fields. However, little is known about the effects manure has on the soil microbiome, which is an important aspect of soil health and fertility. In addition, due to the subtherapeutic levels of antibiotics necessary to keep the animals healthy, CAFO manure has elevated levels of antibiotic resistant bacteria. Using 16s rRNA high-throughput sequencing and qPCR, this study sought to determine the impact of swine CAFO manure application on both the soil microbiome and abundance of select antibiotic resistance genes ...
