Download or read book Using Elemental Sulfur to Optimize lower Soil Ph of Bentgrass Putting Greens written by Derek Pruyne and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil pH highly influences nutrient availability and root growth during both establishment and maintenance of creeping bentgrass (Agrostis stolonifera L.) putting greens (PGs). The optimal 1:1 soil pH range for creeping bentgrass is 5.5--6.5, yet PG rootzones containing even modest amounts of calcareous sand are often buffered to higher pH values. Furthermore, topdressing sand and/or irrigation water inputs are common sources of added alkalinity. Supraoptimal pH levels have been shown to increase turfgrass disease susceptibility while limiting nutrient availability, root growth, and stress tolerance. The objective of this research was to quantify growth and nutritional status responses of bentgrass PGs to method and/or rate of a single elemental sulfur (So) application. In Sept. 2012, pelletized or flowable So was applied to two internally-drained Penn A-series PGs at rates of 0, 195, 390, 586 kg So ha--1 (0, 4, 8, or 12 lbs So 1000 ft2). Response variables measured over the 2013 season were: clipping yield, canopy color and density, soil pH (by 3 rootzone depth segments), soil extractable nutrients, leaf nutrient content, specific root length, and root length density. Soil pH reductions observed within the surface 5-cm and 5 to 15-cm rootzone depths were highly correlated to So rate. Other response variables significantly influenced by linear So rate include leaf nutrient concentrations (Ca, K, Mg, S, Cu, and Fe) and canopy density. While canopy color, determined by dark green color index (DGCI), was not influenced by linear So rate, there was a significant effect of application method. Several of the described experimental variables measured proved statistically significant; however, observed differences were often marginal. Nutrient levels of all treated and untreated plots remained within the sufficiency range of creeping bentgrass. The most notable nutritional difference was that of leaf Mn concentrations. Mean leaf Mn increased approximately 20-40% in treated plots. Despite frequent visual inspection of the sand rootzone in the months following application, no evidence of black layer (precipitated manganous- or ferrous-sulfide) was observed.

Download or read book Ecophysiology of High Salinity Tolerant Plants written by M. Ajmal Khan and published by Springer Science & Business Media. This book was released on 2006-05-16 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The halophytes are highly specialized plants, which have greater tolerance to salt. They can germinate, grow and reproduce successfully in saline areas which would cause the death of regular plants. Most halophytic species are found in salt marsh systems along seashores or around landlocked inland lakes and flat plains with high evaporation. The halophytes play very significant role in the saline areas specially in the coast by overcoming the salinity in different ways, viz. with regulating mechanisms in which excess salts are excreted and with out regulating mechanism, which may include succulents or cumulative types. Besides that they protect coast from erosion and cyclones, provide feeding ground and nursery for fish, shrimps and birds. Halophytes get increasing attention today because of the steady increase of the salinity in irrigation systems in the arid and semi-arid regions where the increasing population reaches the limits of freshwater availability. In many countries, halophytes have been successfully grown on saline wasteland to provide animal fodder and have the potential for rehabilitation and even reclamation of these sites. The value of certain salt-tolerant grass species has been recognized by their incorporation in pasture improvement programs in many salt affected regions throughout the world. There have been recent advances in selecting species with high biomass and protein levels in combination with their ability to survive a wide range of environmental conditions, including salinity.

Download or read book Beneficial Co Utilization of Agricultural Municipal and Industrial by Products written by Sally L. Brown and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: Co-utilization or blending of residuals offers a unique opportunity to develop products with particular characteristics that are able to target specific customer needs. The very notion of deliberately blending by-products suggests that the recycling and beneficial reuse industries are taking a quantitative step forward towards developing products rather than simply reusing residuals. At the same time that this step provides unique opportunities, it also presents unique challenges. The science associated with the beneficial use of one product may not apply when that product is mixed with another residual. Blending of materials may alter the chemistry of the components of the mixture. This may offer additional benefits, as in the case of disease suppression in composts, or present unexpected problems, as the use of lime-stabilized biosolids has done in Maryland. This book consists of the proceedings of the Beltsville Symposium. The organizers of the Symposium attempted to structure a meeting that would outline both the potential benefits of co-utilization as well as concerns. The editors have divided the proceedings into sections that describe the practical basis for co-utilization of residuals as well as the potential benefits. Specific considerations are described. Finally, case studies include descriptions of successful operations and data that detail results of research involving co-utilization materials. Blending of materials for specific objectives needs to be the focus of any successful co-utilization effort. The scientific implications of the mix need to be determined before a product can be used properly.

This book presents various scientific views and concepts, research, reviews, and case studies on contemporary environmental issues in changing climate scenarios and highlights different adaptation measures. Increasing awareness of modern-day patterns of climate change, it addresses questions often raised by environmental scientists, researchers, policymakers and general readers.
Download or read book Essay on the Geography of Plants written by Alexander von Humboldt and published by University of Chicago Press. This book was released on 2010-07-15 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The legacy of Alexander von Humboldt (1769–1859) looms large over the natural sciences. His 1799–1804 research expedition to Central and South America with botanist Aimé Bonpland set the course for the great scientific surveys of the nineteenth century, and inspired such essayists and artists as Emerson, Goethe, Thoreau, Poe, and Church. The chronicles of the expedition were published in Paris after Humboldt’s return, and first among them was the 1807 “Essay on the Geography of Plants.” Among the most cited writings in natural history, after the works of Darwin and Wallace, this work appears here for the first time in a complete English-language translation. Covering far more than its title implies, it represents the first articulation of an integrative “science of the earth, ” encompassing most of today’s environmental sciences. Ecologist Stephen T. Jackson introduces the treatise and explains its enduring significance two centuries after its publication.
