Barnes and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The polymer, polyacrylamide (PAM), is a high molecular weight, chemical anionic polymer that is prescribed and used for irrigation improvement in row crops primarily in the United States. A field research study was conducted in 2014, 2015 and 2016 in Northeast Arkansas to evaluate how addition of PAM in furrow irrigation affected soil erosion, water infiltration, movement of nutrients and sediments, and crop yields in cotton (Gossypium hirsutum). Overall results from the study were mixed. Sediment loss was similar among treatments. Irrigation advancement rates were not significantly different. No differences in crop yield were observed associated with PAM. Differences in results from previous positive observations in Western United States cropping systems may be explained by precipitation, soil type, cropping systems, and precision leveling common in the Midsouth region. From this study, PAM did not show promising results to be a widespread farm management practice in Midsouth with furrow irrigation.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Eroded soil discharged from construction sites is a major water quality issue. North Carolina regulations require that the turbidity of discharged waters from construction sites to non-trout streams or reservoirs not exceed 50 nephelometer turbidity units (NTU) and 10 NTU in trout waters. Polyacrylamide (PAM) has been demonstrated to reduce erosion and turbidity in runoff, but there is little information on the interactions between PAM properties and that of the water or suspended solids. Our study tested eight PAM products (Cytec Superfloc A100, A110, A150, N300, 1606; Ciba Soilfix Polybead; Applied Polymer Systems 705; Chemtall 923VHM) at concentrations from 0 to 10 mg L-1 for turbidity reduction in suspensions of 13 soils from active construction sites around North Carolina. For five soil suspensions, with turbidities of up to 3000 NTU, PAM reduced turbidity to below 50 NTU in 30 s. In addition turbidity reductions to the 10 NTU level were observed for two soils. Overall, turbidity reductions of greater than 86% were achieved for all soils. Optimal PAM concentrations of soils tested were 1-2 mg L-1, with higher concentrations causing turbidity increases in some soils. Sediment properties drastically affected the response to PAM, which indicates the need to have site-specific recommendations for PAM use. Sediments with turbidity reductions below the 50 NTU standard had kaolinite as the dominant clay mineral (70-90%), a pH between 5-6, and very low organic matter. Soils from the Coastal Plain had poor turbidity reduction with most PAMs. APS705, which contains a mixture of polymers with different molecular weights and charge density, was the only polymer that effectively reduced turbidity in all Coastal Plain soils. An evaluation using combinations of low and high molecular weight PAM products to try and mimic APS705 effects gave limited turbidity reduction of Coastal Plain soil suspensions. Combined treatment of gypsum and PAM appears to have either positive or neg.

Book excerpt: Will over-population, global poverty, widespread hunger and environmental degradation lead to the collapse of human civilization? This book provides a dispassionate analysis of the state of these problems in the world. Avoiding hyperbole and without minimising the dangers, it explains why the future should be faced with confidence. Progress in managing the world's natural resources in ways that are sustainable - environmentally, economically, socially and nutritionally - is too slow because knowledge is too limited. The increased knowledge that is urgently needed can only come from the global network of agricultural research. Yet governments in both the North and South are starving research of the resources that it must have. Unless present policies are changed, the international research network - mankind's lifeline to the future - will be rendered ineffective. The author argues his case in a jargon-free way that will appeal to a wide range of readers concerned with the future of humankind.
