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. Long-term treatment combinations affected (P

This book was released on 2015 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adoption of management practices that maintain or increase soil organic matter (SOM), which contains 58% carbon (C) on average, may help to mitigate climate change by sequestering atmospheric C. Therefore, the main objective of this study was to determine the long-term trends in SOM, soil C and nitrogen (N), bulk density, various soil chemical properties (i.e., pH, electrical conductivity [EC], and Mehlich-3-extractable nutrients) in the top 10 cm, and soybean yield as affected by residue burning (burning and non-burning), tillage (conventional and no-tillage), irrigation (irrigated and non-irrigated), and N-fertilization/residue level (high and low) in a wheat (Triticum aestivum L.)-soybean [Glycine max (L.) Merr.], double-crop system in eastern Arkansas. The secondary objective was to determine the relationship between soil water potential (-MPa) and soil water content (g g-1) in the top 7.5 cm as affected by residue treatments. The field site has been consistently managed for 13 years at the University of Arkansas Lon Mann Cotton Research Station near Marianna, Arkansas on a Calloway silt loam (fine silty, mixed, active, thermic Glossaquic Fraglossudalf). Averaged across all other factors, SOM did not differ over time (P > 0.05) under irrigation, while SOM content increased over time (P
Book Synopsis Long-term Residue and Water Management Effects on Soil Respiration and Soil Aggregate Stability in a Wheat-soybean, Double-crop System in Eastern Arkansas by : Sharon Faye Smith
Download or read book Long-term Residue and Water Management Effects on Soil Respiration and Soil Aggregate Stability in a Wheat-soybean, Double-crop System in Eastern Arkansas written by Sharon Faye Smith and published by . This book was released on 2013 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability in agriculture is paramount to assuring continued production from our most naturally fertile soils. Storing carbon (C) in soil as organic matter through sustainable agricultural management practices can both remove atmospheric C and improve soil quality. The objective of this study was to evaluate the long-term effects of water management (irrigation and dryland), residue management [burn and no-burn, conventional (CT) and no-tillage (NT)] and residue/fertility level (high and low) on soil respiration and aggregate stability in a wheat- (Triticum aestivum L.) soybean [ Glycine max (L.) Merr.], double-crop system in a silt-loam soil (Aquic Fraglossudalf) in the Mississippi River Delta region of eastern Arkansas after more than six years of consistent management. To this end, soil respiration was measured every two weeks during the 2011 and 2012 soybean growing seasons. A wet-sieving procedure was used to assess total and size-separated (i.e., 0.25-0.5, 0.5-1, 1-2, and > 2 mm diameters) water-stable aggregates (WSA). Soil respiration was greater under irrigation and CT on the majority of days sampled and averaged 27.4 and 16.3% greater than under dryland and NT management, respectively. Soil respiration was reduced by an average of 9.7% by residue burning, as compared to non-burning. The effects of residue level, achieved by differential N-fertilization, on soil respiration were inconsistent and generally non-significant. Soil water-stable aggregates were unaffected by burning, but were affected by all other field treatments. Total WSA concentrations were 19% greater under CT than NT within the dryland-low-fertility treatment combination. Total WSA concentrations under high-fertility were 18% less than under low-fertility within the irrigated-NT treatment combination, despite greater residue levels produced within the high-fertility treatment. The smallest two size classes (i.e., 0.25 to 0.5 and 0.5 to 1.0 mm) comprised over 80% of the total WSA. The WSA concentrations of the largest two size classes (1- to 2- and >2-mm) were unaffected by all treatments imposed. Understanding how long-term agricultural management practices affect soil C storage and cycling can help improve policies for soil and environmental sustainability throughout the lower Mississippi River Delta region.

Download or read book Evaluation of the Sustainability of Residue and Water Management Practices in a Wheat-soybean Double-crop Production System in Eastern Arkansas written by Tarra Leigh Verkler and published by . This book was released on 2007 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable agricultural practices are becoming an increasingly recognized issue. Crop residue management practices can play a significant role in agricultural sustainability. The objective of this study was to investigate residue management [i.e., high and low residue level, burned and unburned residue, and conventional tillage (CT) and no-tillage (NT)] and water management (i.e., irrigated and non-irrigated) effects on soil properties, soil moisture dynamics, and soybean production in a wheat-soybean double-crop system in eastern Arkansas for two complete cropping cycles. While soil properties were not consistently affected by residue management, NT consistently, though non-significantly, conserved soil water more effectively than CT. Soybean yield was unaffected by residue management. In 2006, the estimated net return from the high-residue/burned/NT/irrigated treatment combination was 26% greater than the high-residue/burned/CT/irrigated treatment combination. The more environmentally sustainable practice of NT appears to be a viable, and potentially more profitable, alternative to the more common practice of CT.

Download or read book Climate Science, Solutions and Services for Net Zero, Climate-Resilient Food Systems written by Pete Falloon and published by Frontiers Media SA. This book was released on 2024-05-06 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food systems are both a major contributor to global greenhouse gas emissions and are strongly impacted by climate change and weather extremes. Solutions to deliver net-zero food systems, therefore, need to take climate impacts, adaptation, and resilience into account in order to ensure they are appropriate in a changing climate and do not conflict with adaptation goals. In a similar way, adaptation options for the food system must consider potential trade-offs, consequences, and synergies with net-zero and other objectives such as the Sustainable Development Goals. Solutions for net-zero, climate-resilient food systems will therefore require systematic, interdisciplinary approaches across academia, governments, business, NGOs, and the public.
Book Synopsis Short-term Effects of Winter Cover Crops on Soil Properties, Yield, and Partial Returns in a No-tillage Soybean Rotation by : Drew Dillion Kirkpatrick
Download or read book Short-term Effects of Winter Cover Crops on Soil Properties, Yield, and Partial Returns in a No-tillage Soybean Rotation written by Drew Dillion Kirkpatrick and published by . This book was released on 2021 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cover crops have the potential to provide many benefits including weed suppression, erosion control, and improvements to soil quality. These benefits can be affected by species, biomass accumulation, and management practices. Although large amounts of biomass are good for maximizing benefits, it can result in problems for establishing the subsequent crop. Soybean [Glycine max (L.) Merr.] accounts for over 50% of Arkansas crop hectares annually; therefore, understanding the effect that a cover crop can have on the following soybean crop is crucial to the successful implementation of cover crops within the state. A study was established to evaluate winter cover crops as an alternative to traditional Arkansas practices, such as winter fallow, as well as winter wheat (Triticum aestivum L.) soybean double-crop system, and the effect each cropping system has on soybean yield and partial returns. Additionally, a goal of this study was to assess a variety of cover crop species and blends as well as their effect on aboveground biomass accumulation, nutrient uptake, and stand establishment of the following soybean crop. Soil organic matter (SOM) and pH were also used to evaluate overall soil health following three full rotations of each winter treatment. Results of the study show that winter cover crops do not affect the following soybean crop establishment, but had a positive influence on soybean yield and partial returns in a no-tillage system. Except for blue lupin (Lupinus angustifolius), each cover crop treatment proved to be an equally viable alternative to a traditional double-crop system and more profitable than a winter fallow system. Cover crops not only have an immediate impact of increasing soybean yield, but cover crops also have the potential to provide long-term benefits. Previous research has shown that increased biomass production typically increases SOM and results of this study indicate that cover crop treatments produced up to four times as much aboveground biomass compared to a winter fallow management strategy. Treatments that produced the most biomass also accumulated the most aboveground nutrient contents for the macronutrients nitrogen (N), phosphorus (P), and potassium (K). There were no differences in soil health calculations, but each treatment received a "good" soil health score. Our results indicate that winter cover crops provide a promising alternative to the winter wheat soybean double-crop system and winter fallow management program and with continuous management, soil quality can be improved.

Book Synopsis The Importance of Soil Organic Matter by : Alexandra Bot
Download or read book The Importance of Soil Organic Matter written by Alexandra Bot and published by Food & Agriculture Org.. This book was released on 2005 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and biological activity of soil organisms; and plant nutrient availability. This document concentrates on the organic matter dynamics of cropping soils and discusses the circumstances that deplete organic matter and their negative outcomes. It then moves on to more proactive solutions. It reviews a "basket" of practices in order to show how they can increase organic matter content and discusses the land and cropping benefits that then accrue.--Publisher's description.
Book Synopsis The Effect of Plant Cutting and Burndown Herbicides on Weed Management in Double-crop Soybeans Following Winter Wheat by : Colton P. Carmody
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.

Download or read book Root Zone Water Quality Model written by Lajpat Ahuja and published by Water Resources Publication. This book was released on 2000 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication comes with computer software and presents a comprehensive simulation model designed to predict the hydrologic response, including potential for surface and groundwater contamination, of alternative crop-management systems. It simulates crop development and the movement of water, nutrients and pesticides over and through the root zone for a representative unit area of an agricultural field over multiple years. The model allows simulation of a wide spectrum of management practices and scenarios with special features such as the rapid transport of surface-applied chemicals through macropores to deeper depths and the preferential transport of chemicals within the soil matrix via mobile-immobile zones. The transfer of surface-applied chemicals (pesticides in particular) to runoff water is also an important component.
