[Source: Use the tool for free at LogItEasy.com. FIG.

And the logs look great!". Passwords are issued subject to review and approval by LOGitEASY. I hope you find it useful for your business. Soil Texture Calculator Use this online tool to calculate a single point texture class based on percent sand, silt, and clay. "The LOGitEASY Field Form is much easier and faster to use than Excel, Visio or AutoCad to create boring logs. dom_i.query(this).css("float","none"); If the drying of the silt reduces the LL by 30% or even more, the soil is organic else the soil is inorganic silt. USCS Calculator for those of you that classify soil according to the ASTM Visual-Manual Procedure (ASTM-D2488) and record only the percentage of gravel, sand, and fines in the field, without the soil group name and symbol.

Calculate the CC and CU. According to the Unified system of soil classification, the soil is fine-grained if more than 50% of the soil passes through 0.075mm sieve. imgWidth = imgWidth.replace("px",""); General.

(75-mm) portion, indicate its presence by the term trace, for example, trace of fines. Including the optional sand fractions will refine the calculation. In this method the classification is done by considering the Atterberg limit and textural soil classification. The Unified Soil Classification System (USCS) is a soil classification system used in engineering and geology to describe the texture and grain size of a soil.The classification system can be applied to most unconsolidated materials, and is represented by a two-letter symbol. Students and young professionals are welcome to use the USCS Calculator for learning the first part of this soil classification procedure online.

The USCS Calculator is the core of our Pro Soil Logging Functionality. Simulate soil water tension, conductivity, and water holding capability based on the soil texture with adjustments to account for gravel content, compaction, salinity, and organic matter. var imgMarginTop = dom_i.query(this).css("margin-top") == undefined ? (75 mm), estimate and note the percentage, by dry weight, of the gravel, sand, and fines (Section 12.3). USCS Calculator - Quick Start Instructions: USCS Calculator - Learn the ASTM Visual-Manual Procedure: The soil is fine grained if it contains 50 % or more fines (Section 13.1). Unified Soil Classification System: Field Method 1 Department of Sustainable Natural Resources. A detailed analysis of the USCS and other soil classification systems highlighted previously readily discloses great physical insight and understanding of soil behavior and their properties. if(imgWidth.indexOf("px") > 0){ var imgMarginRight = dom_i.query(this).css("margin-right") == undefined ?
