This book was released on 2012-12-06 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna and broader dissemination. tional publishing house to assure improved service Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work.

This book was released on 2017 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving the understanding of conventional and alternative management practices and their interactions on aggregate-derived particulate organic matter (POM) fractions and soil hydraulic properties, particularly infiltration, is instrumental to soil and groundwater management and long-term sustainability in the Lower Mississippi River Delta (LMRD) region of eastern Arkansas. The objective of this long-term wheat (Triticum aestivum L.)-soybean (Glycine max [L.] Merr.), double-crop (WSDC) field study in a silt-loam soil (Glossaquic Fraglossudalf) in the LMRD region of eastern Arkansas was to evaluate the effects of conventional and alternative management practices, including wheat-residue level, residue burning, tillage and irrigation, on i) POM fractions and the distribution of C and N among POM fractions, including the total POM, light fraction (LF) and intra-POM (iPOM) fraction, in the top 10 cm of soil after 14 years of consistent management and ii) falling-head and tension infiltration after 11 and 14 years of consistent management.

Download or read book The Effect of Plant Cutting and Burndown Herbicides on Weed Management in Double crop Soybeans Following Winter Wheat written by Colton P. Carmody and published by . This book was released on 2021 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The agricultural practice of 'double-cropping,' harvesting two crops from the same piece of land in a single growing season, is a popular practice in Southern Illinois where growers often plant soybeans (Glycine max (L.) Merr.) soon after winter wheat (Triticum aestivum L.) harvest. Horseweed (Conyza canadensis L. Cronq.) competition and lack of control can cause detrimental effects on yield for double-crop producers in Illinois due to the development of multiple herbicide resistance in this weed species. To combat this problem of herbicide resistance, new herbicide-tolerant soybean technologies and new herbicide formulations have been developed, but these technologies will quickly lose efficacy unless stewarded properly. Therefore, our objective for this study was to evaluate the control of horseweed and other weeds and crop yield as influenced by weed-cutting height, herbicide treatments, timing of herbicide application in three studies (a greenhouse study and in-crop and non-crop field studies) with the goal of improving weed management in double-crop soybean. Data obtained from the non-crop study that focused on the evaluation of different cutting heights, herbicide treatments and application timings was observed to be significantly different by weed species evaluated: horseweed, common ragweed (Ambrosia artemisiifolia L.), and Canada goldenrod (Solidago canadensis L.). Horseweed control and biomass accumulation was observed to be strongly influenced by cutting height, where cutting to 15 cm resulted in the greatest control efficacy and reduction in overall biomass irrespective of herbicide treatment used. While application timing following cutting in relation to control efficacy and biomass accumulation was only observed to be significant based upon the translocation properties of the herbicide applied, i.e. contact or systemic. Differences in the perennial weed species Canada goldenrod were observed compared to horseweed; cutting in combination with herbicide treatments resulted in a decrease in control compared to herbicide applications made to noncut Canada goldenrod plants. Data obtained in this study suggest that cutting in combination with the use of effective burndown herbicides may lead to increased control of certain weed species and could be a component of herbicide technology stewardship in double-crop soybeans. The in-crop study focused on evaluating yield potential of burndown herbicides in double-crop soybean systems. Observations from this study revealed that similarly to full-season beans, yield in double-crop soybeans was limited dependent upon the burndown herbicide programs ability to achieve broad-spectrum weed control. When effective burndown herbicides dicamba, glufosinate, and paraquat were combined with herbicides that possessed the ability to provide soil residual activity, such as saflufenacil, chlorimuron, chloransulam, metribuzin, sulfentrazone or flumioxazin, yield potential was maximized compared to these active ingredients applied as standalone treatments. Data from this study further stresses the importance of utilizing multiple effective sites of actions to achieve higher yields while maintaining good herbicide stewardship practices.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrating crop and livestock is being considered to improve soil health by carbon sequestration. A two-year study (2019-2021) at CPBES in Newton, MS was aimed to evaluate soil microbial diversity in the warm, humid regions, specifically southeastern USA. Amplicons targeting bacterial 16S rRNA genes and fungal ITS2 regions were sequenced. Taxonomic assignment and microbial diversity characterization were performed using QIIME2®. Soil fungal diversity showed significant differences (alpha diversity, p = 0.031 in yr. 2020 and beta diversity, p = 0.037 in yr. 2021). Canonical Correspondence Analysis (CCA) and Mantel test showed significant influence on fungal diversity due to carbon (rm = 0.2581, p = 0.022), nitrogen (rm = 0.2921, p = 0.0165) in yr. 2021, and on bacterial diversity due to EE-GRSP (rm = 0.22, p = 0.02) in yr. 2020. Long term study of ICLS can help us better understand the shift in microbiome to improve crop production sustainably.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is the foundation for human civilization - it is the literal foundation of our homes, the source of raw materials, a filter and storage system for the water we drink, a medium for plant growth, and a habitat for many organisms. Keeping the soils of our planet healthy to carry out these functions is incredibly important. In agriculture, there is a building movement to study and improve soil health across the landscape, of which this research is a small part. This body of research addresses several areas within soil health; how we define and test for healthy soil, practices that may help build healthier soil, and some of the practical challenges of managing for soil health. We specifically focused on annual row crop systems in the North Central US region, and in particular soybean production. First, we focused on a few practical soil health tests that could be adopted by farmers - linking these measurements to both historical management and soybean yield. This study was a community-science project that relied on the help of Wisconsin soybean farmers to sample their fields and relay management information. The results of this study will help direct future research and identified crop rotation as a key area for soil health improvement. Next, we examined some common production practices related to building soil health and their effects on crop yield using long-term crop rotation studies. We looked at the effects of tillage, crop rotation, and foliar fungicide use on corn and soybean yield, and the legacy effect of the latter two of these treatments on soil fungal populations. Microbial communities carry out critical functions in soil, so it is important to understand how human activity shapes their populations. Finally, another long-term rotation study was used to look at the feasibility and yield effects of establishing cover crops, a key soil health practice, in annual row crop systems in Wisconsin. Overall, this work identifies avenues for both measuring and improving soil health in North Central US soybean.
