Book excerpt: Excerpt from Supplement to Physical Characteristics of Some Representative Louisiana Soils In recent years increased attention has been focused on soil moisture control as another way of improving farm efficiency. In Louisiana, this may involve water removal by drainage, irrigation, or a combination of drainage and irrigation. Rainfall, particularly since 1950, has been such that periods of inadequate, or quite excessive, rainfall have occurred almost every year during the growing season.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Louisiana Conservationist, Vol. 8: October, 1955 The carrying capacity of any body of water for fish is normally dependent upon the volume of fish food available. The quantity of fish food present is a direct result of the general water fertility. The water fertility of a body of water is dependent pri marily upon the fertility of its watershed. The watershed of all bodies of water of the type entitled Impoundments consists of infertile soils. Therefore, their carrying capacity of fish is low, probably in all cases less than 200 pounds of fish per surface acre. Other types of water in Louisiana have a carrying capacity for fish of 200 to 800 pounds of fish per surface acre. The results of a survey of the fish populations of some representative Impound ments, which are summarized below, illustrates their low carrying capacity for fish.

Download or read book Deep Tillage Investigations on Alluvial Soil in the Sugarcane Area of Louisiana Classic Reprint written by Irwin L. Saveson and published by Forgotten Books. This book was released on 2017-11-19 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Deep-Tillage Investigations on Alluvial Soil in the Sugarcane Area of Louisiana Although no significant crop response was obtained in the tests in 1957-59 and 1961-62 on silt loam alluvium, there was a significant soil physical response. The explanation for the lack of crop response is not known. One influential factor may have been the relatively high yield of the conventional plots. The average crop response of tests in 1955-59 and 1961-62 on silty clay loam alluvium for subsoiling 14 and 18 inches deep was standard tons per acre; plowing 14 inches, and plowing 18 inches, The crop response obtained by deep plowing 14 inches deep on 16 replications was significant at the 5-percent level, and that by deep plowing 18 inches deep on 26 replications was significant at the l-percent level. The tillage treatments caused little change in the soil physical characteristics. No crop responses were obtained from deep tillage tests in 1955-56 on clay alluvium or in tests in 1957-58 on loess silt loam uplands, although the soil properties of the silt loam uplands did change. Limited soil moisture studies indicate that during periods of sparse rainfall the deep-tilled plots contained more moisture at the 0 to 12-inch depth than conventional plots. These plots also showed a greater moisture extraction at the 24 to 36-inch depth, which indicates a deeper rooted crop. In a sugarcane x tillage interaction study, the variety C. P. 44-101 produced a significantly higher yield of standard tons per acre from the'14-inch deep-plowed treatment, as com pared with the 14 or 18-inch subsoiled treatment. The reverse was true with the variety C. P. 36-105, which produced more standard tons per acre from the subsoiled treatment. The reverse was true with the variety C. P. 36-105, which produced more standard tons per acre from the subsoiled treatment. In other studies, the variety c.p. 44-101 showed the same pattern of tillage treatment response.

Download or read book Soils of the Eastern United States and Their Use written by Jay A. Bonsteel and published by Forgotten Books. This book was released on 2017-10-26 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soils of the Eastern United States and Their Use: The Memphis Silt Loam The soil type is derived from the weathering of the loess, a silty. Material associated with the glaciation of regions farther north. The Memphis Silt. Loam occurs at all altitudes from 50 feet above sea level in Louisiana to 500 or 600 feet above sea level in Illinois and Missouri. In general the drainage is good, although local areas marked by a gray-surface soil and the presence of iron concretions or iron gravel are in need of tile underdrainage. Owing to its soft, silty nature and its considerable elevation above adjoining bottom lands, a large part of the Memphis silt loam has been subjected to destructive erosion, and in such areas not over 20 per cent of the total extent of the type can be brought under tillage. In other areas, more remote from active stream erosion, fully 35 per cent of the type may be tilled, although erosion still constitutes a serious problem in the handling of this soil.

Download or read book Correlations of Soil and Rock Properties in Geotechnical Engineering written by Jay Ameratunga and published by Springer. This book was released on 2015-12-11 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors' database.
