This book was released on 2018-09-03 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Infiltration and Water Repellency in Granitic Soils The mechanisms involved in the formation of water-repellent soils are not well understood, partly because the hydrophobic compounds have not been identified. These compounds are formed and released from plants and plant residues by decomposition and pyrolysis. They may be formed in the soil by fungi and other microflora (bond and Harris 1964) or they may move into the soil after formation elsewhere.

This book was released on 2018-03-18 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Abstracts of Recent Published Material on Soil and Water Conservation: July 1956 Infiltration studies showed the effective ness of straw mulch as well as grass cover in preventing surface soil sealing and early runoff. With water applied at 3. 3 inches per hour, runoff rates greater than 80 per cent of the applied rate were reached in all cases during wet runs, after a constant infiltration rate was reached. For Austin clay, the constant rates varied from 0. 25 to 0. 59 inch per hour; and for Houston black clay, from 0. 08 to 0. 27 inch. Under natural rainfall conditions the minimum rates for saturated soil probably would be less. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Soil Permeability Determinations for Use in Soil and Water Conservation Classic Reprint written by R. E. Uhland and published by Forgotten Books. This book was released on 2017-10-28 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soil Permeability Determinations for Use in Soil and Water Conservation A knowledge of the rate of movement of water through each significantly different soil horizon has many uses. The amount of water a given soil can transmit during a single rain storm or succession of storms is governed by the permeability of the soil, including its infiltration rate. Runoff is regulated to a great extent by the rate at which water enters the surface soil and percolates to lower depths. In other words, soils which take and transmit water very slowly will give high runoff whenever rains of high intensity and long duration occur. Thus permeability and infiltration data are valuable in over-all planning for irrigation, drainage, erosion control, and flood control.

This book was released on 2017-11-19 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Flow and Retention of Water in Layered Soils Knowledge about the water-retention proper ties of the soil enables one to estimate the need for and the frequency of irrigation. Satisfactory methods are available or being developed (5) that can be used to predict the extraction rate of water from'the soil by growing plants. If one knows how much water is retained for plant use in the soil after irrigation and how fast it is ex tracted, the scheduling of irrigations with reason able accuracy is simple. Such factors as continued deep drainage after irrigation and level of with drawal before irrigation have to be considered.

Download or read book The Water Relation Between Plant and Soil Classic Reprint written by Burton Edward Livingston and published by . This book was released on 2015-06-29 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Water-Relation Between Plant and Soil The work of Dixon and his colleagues, and that of Renner, of Overton, and others have at length placed upon what appears to be a rational physical basis the long-vexed question of the dynamics of the ascent of water in plants, and recent studies of the relation of the evaporating power of the air and that of sunshine to plant transpiration have made it possible at least to begin to consider the problems of the aerial water relation of plants as involving measurable forces or powers. Our knowledge of the subterranean water-relation of plants remains, however, in an exceedingly primitive condition, although the a priori analysis of the problem here involved may be carried forward beyond the ability of present methods to furnish experimental data. Livingston has insisted that the power of the soil to deliver water to root surfaces is the prime external condition determining the moisture supply to plants in non-saline and non-toxic soils, and the same writer has emphasized the need of some adequate method for determining this water-supplying power of the soil.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soil Moisture: A Record of the Amount of Water Contained in Soils During the Month of June, 1895 The records showing the conditions in the West are all commented upon directly under the diagrams. AS a rule, during th1s favorable season the fields under ordinary cultivation and those which had been subsoiled and subsequently cultivated do not Show very different mois ture conditions. In some places the-effect of cultivation is not appar ent upon the moisture content of Soils. For reasons which have already been, given it is not to be expected that cultivation would Show a very marked effect upon the amount of. Moisture in the soil either in a very dry season or in a very favorable sea-son with frequent rains. The time when it would have its maximum effect would be after a wet season and when a dry period was coming on. The moisture content at this time should fall much more gradually in the cultivated than in the uncultivated land. This is shown to a slight extent in some of the records, but not to such an extent as would seem likely to occur under the most intelligent Cultivation of the soil. The small amount of data which has been collected is not sufficient, however, to warrant a close and final judgment in this matter.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Simulating Water Flow in Soil: With an Electrical Resistance Network Water infiltration, redistribution, and removal from soil are important processes that affect all land management systems. Although these processes must be studied under field and laboratory conditions, certain phases can be evaluated by analog techniques with a considerable saving in time and cost and in accuracy. Electrical analogs have been very useful in these evaluations. Two types have been used - with good success: (1) those utilizing the flow of electricity through sheets of electrical conducting paper and (2) those using a network of electrical resistors. Electrical conducting paper can be used to solve steady-state flow problems in porous media that are saturated, isotropic, and homogeneous With respect to its hydraulic conductivity. An electrical re sistance network is more flexible in its use than conducting paper. The network can quickly be adjusted to simulate flow conditions in soils that are homogene ous or stratified, saturated or unsaturated, isotropic or anisotropic. Various investigators have already utilized the network to study flow of water either in homogeneous or stratified medium (1, 6, 7, In this report, the major objective is to present a method for calculating and assembling network resistances to represent water flow in soil. The ap proach used herein is called the building block method. The soil profile is considered to be composed of discrete, rectangular blocks of soil. These blocks are then joined to build the entire soil profile. Each block of soil is represented by a mesh of four resistors. The meshes are then joined to form the network, which, in turn, represents the soil profile. The discussion in this report will deal with representations of steady-state flow of fluid in saturated and unsaturated media. Procedures will be given for representing media that are either homogeneous or stratified and either isotropic or anisotropic with respect to soil hydraulic conductivity. Formulas will be given for calculating resistances when rectangular blocks of different dimensions are used. Special formulas are presented for calculating resistances adjacent to a tubular drain embedded in the soil.
