Leggett and published by . This book was released on 2019 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil pH has been declining in northern Idaho, primarily due to the consistent use of ammonium-based nitrogen fertilizers. The major yield reducing factor in low pH soils is increased aluminum (Al) toxicity. Research is needed to determine the rates of lime needed to ameliorate the acidic soil and the economic rate of return for those rates. Studies were conducted in the greenhouse and field to explore the response of Rhizoctonia oryzae, R. solani AG-8, and Fusarium culmorum to increases in soil pH with liming. Results indicate that incidence and severity of Rhizoctonia root rot and Fusarium crown rot is likely to increase when soil pH increases with liming and that a soil pH value of 6 is optimal for these pathogens. A second component of the research was to establish long-term field studies in northern Idaho to explore the effect of three liming rates (2,242; 4,484; and 6726 kg ha-1) on ameliorating soil pH and examine the economic feasibility of these treatments. Trials were conducted at five locations for 2 years and all three lime rates significantly increased soil pH in the top 7.5 cm at all sites, with some sites experiencing increases in the 7.5 to 15 cm range. The increased pH was associated with significantly increased base saturation and reduced Al concentrations at all sites as well. Yields were increased with increasing rates of lime at many of the sites. Net present value was used to amortize the cost of liming over multiple years. Based on the data from this study, there was an economic benefit to liming in five of the seven site-years, with an average of $21, $26 and $39 ha-1 net returns for the 2,242; 4,484 and 6,726 kg ha-1 lime rates, respectively. Preliminary data suggests that lime application in soils with documented acidification may be economically beneficial for growers in northern Idaho.

Download or read book Soil Health and Climate Change written by Bhupinder Pal Singh and published by Springer Science & Business Media. This book was released on 2011-07-24 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Soil Health and Climate Change” presents a comprehensive overview of the concept of soil health, including the significance of key soil attributes and management of soil health in conventional and emerging land use systems in the context of climate change. Starting with a review of the physical, chemical and biological indicators of soil health and their significance for monitoring the impacts of climate change, this book then focuses on describing the role of soil structure, pH, organic matter, nitrogen, respiration and biota in sustaining the basic functions of soil ecosystems, and their anticipated responses to climate change. Further topics include the management of cropping, pastoral, and forestry systems, and rehabilitated mine sites, with a focus on mitigation of and adaptation to climate change impacts. Finally, the opportunities and potential risks of organic farming, biochar and bioenergy systems, and their ability to sustain and even enhance soil health, are discussed.

Download or read book Agronomic and Economic Response of Hard Red Winter Wheat to Multiple Liming and Fertilization Strategies written by Romulo Pisa Lollato and published by . This book was released on 2012 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: Application of agricultural lime is the most frequently recommended method for managing low soil pH; however, in-furrow phosphorus (P) fertilizer or pelletized lime are also commonly used to ameliorate soil acidity. The objectives of this study were to evaluate three soil acidity amendment strategies for winter wheat production. The effects of broadcast agricultural lime (2.25 or 4.50 Mg ECCE ha-1), banded pelletized lime (225 or 450 kg ha-1 yr-1), and banded P fertilizer (28 or 56 kg ha-1 yr-1) on bulk soil pH, aluminum saturation (Alsat), pH change in the soil profile, wheat vegetative development, plant population uniformity, and grain yield, were investigated during three growing seasons in a Grandfield Fine Sandy Loam and a Grant Silt Loam with initial soil pH of 4.8 and 4.9 at Altus and Waukomis, OK. Broadcast agricultural lime at 4.50 Mg ha-1 increased soil pH by one unit and decreased Alsat by 98% at Waukomis. Neither banded pelletized lime nor P fertilizer affected these parameters in either location. Changes in soil pH caused by banded pelletized lime were restricted to the region surrounding the pellet, while broadcast agricultural lime increased soil pH throughout the profile. In-furrow P fertilizer increased vegetative growth and plant population homogeneity in all years of the study at Waukomis; broadcast lime provided similar results in 2010-11 when low soil pH effects on crop growth were more apparent due to severe drought. Wheat grain yield was not affected by treatment, probably due to low soil Alsat. When broadcast lime costs were amortized over five years, 2.25 Mg ECCE ha-1 and the control resulted in the highest net returns among treatments. Results indicate that banded P fertilizer or broadcast agricultural lime can increase early-season wheat growth and population uniformity in a low-pH soil, but this increase in vegetative growth might not result grain yields significantly higher than the control when Alsat is lower than 10%.

Available in PDF, EPUB and Kindle. Book excerpt: "Decreasing soil pH, also called soil acidification, is a growing concern in eastern Washington and northern Idaho. Researchers and farmers have measured soil pH values below 5.0 throughout the Palouse region, in particular. Decreasing soil pH has serious implications for the cropping systems of the Palouse. This publication, FS169 - An Introduction, is part of a series on soil acidification and covers the fundamentals of soil pH and acidification. The series continues with other fact sheets on more specific topics such as the influence of pH on pathogens and microbes, recommended varieties of specific crops, herbicide activity, crop nutrition, and liming."--Abstract

Book excerpt: Soil pH can have an influence on the outcome of root diseases caused by soilborne pathogens, but it depends on the pathogen. Cereal growers in the Pacific Northwest (PNW) have been experiencing an increase in soil acidity (lower pH) primarily due to a long history of ammonium fertilizer use. In eastern Washington and northern Idaho, soil acidification tends to be worse in areas that are annually cropped, do not include nitrogen-fixing legumes in the crop rotation, and in areas that were historically forested. Plant disease is the outcome of three interacting components: the pathogen, the plant, and the environment. Soil pH, a component of the environment, influences both the pathogen and the host.

This book was released on 1991-02-01 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest is growing in sustainable agriculture, which involves the use of productive and profitable farming practices that take advantage of natural biological processes to conserve resources, reduce inputs, protect the environment, and enhance public health. Continuing research is helping to demonstrate the ways that many factorsâ€"economics, biology, policy, and traditionâ€"interact in sustainable agriculture systems. This book contains the proceedings of a workshop on the findings of a broad range of research projects funded by the U.S. Department of Agriculture. The areas of study, such as integrated pest management, alternative cropping and tillage systems, and comparisons with more conventional approaches, are essential to developing and adopting profitable and sustainable farming systems.
