TL;DR: An intensive soil survey of about 79% of the 280,000 m/sup 2/ of Los Alamos County was made to identify the kinds of soils in the area, where they are located, and how they can best be used as discussed by the authors.
Abstract: An intensive soil survey of about 79% of the 280,000 m/sup 2/ of Los Alamos County was made to identify the kinds of soils in the area, where they are located, and how they can best be used. A soil survey map is included, with detailed soils information presented in the report. Past and present land use in the Los Alamos area is discussed and general information about soils and their formation is evaluated, including the regional soil formation factors of geologic parent materials, climate, living organisms, topography, and time. The soils of the area are classified according to the current system of soil classification and described in detail. The relationship of soil formation to classification is discussed and the current soil classification system is explained. General and detailed descriptions are given for each of the 61 soil mapping units, and include information on soil color, texture, structure, consistence, clay films, coarse and fine fragment distributions, permeability, depth, hydrologic properties, pores, pH, and soil horizon boundaries. Soil mapping units are also described relative to their specific soil formation factors. The use and management of these soils for engineering and recreational purposes are also considered.

TL;DR: In this article, the available moisture capacity as related to rainfall pattern and potential evaporation is discussed and accordingly demarcation of bench mark soil areas along with their suitability for specific crops is attempted to furnish reliable data for research and extension workers.
Abstract: Soil maps which are the end products of soil survey, are utilized to abstract soil characteristics through soil classification and define environmental relationships of soils to evolve guidelines for proper use and management. The concept that the soils differ in their characteristics within an area of a given climatic type is reflected in moisture properties pertaining to the soils of the area. Geographical distribution of soil series and associations in the semi-arid tract of Hissar, Haryana having varying available moisture capacities is indicated in the map. The available moisture capacity as related to rainfall pattern and potential evaporation is discussed. Utilization of moisture by specific crops in different soils is also highlighted and accordingly demarcation of bench mark soil areas along with their suitability for specific crops is attempted to furnish reliable data for research and extension workers.

TL;DR: In this article, a method for storing and retrieving soil survey data is described, which is of particular use for permanent irrigated horticultural crops, where new decisions on land use may be made at intervals of several decades.
Abstract: Summary A method by which soil survey data can be stored and readily retrieved is described. The advantages of this method over the traditional technique of preparing maps from soil survey data are indicated. The technique is of particular use for permanent irrigated horticultural crops, where new decisions on land use may be made at intervals of several decades. The preparation of soil maps, based on varying criteria, by those other than the soil surveyor, is facilitated.
