  • The Soil Survey
    The Soil Survey The soil survey delineates the basal soil pattern of an area and characterises each kind of soil so that the response to changes can be assessed and used as a basis for prediction. Although in an economic climate it is necessarily made for some practical purpose, it is not subordinated to the parti­ cular need of the moment, but is conducted in a scientific way that provides basal information of general application and eliminates the necessity for a resurvey whenever a new problem arises. It supplies information that can be combined, analysed, or amplified for many practical purposes, but the purpose should not be allowed to modify the method of survey in any fundamental way. According to the degree of detail required, soil surveys in New Zealand are classed as general, . district, or detailed. General surveys produce sufficient detail for a final map on the scale of 4 miles to an inch (1 :253440); they show the main sets of soils and their general relation to land forms; they are an aid to investigations and planning on the regional or national scale. District surveys, for maps, on the scale of 2 miles to an inch (1: 126720), show soil types or, where the pattern is detailed, combinations of types; they are designed to show the soil pattern in sufficient detail to allow the study of local soil problems and to provide a basis for assembling and distributing information in many fields such as agriculture, forestry, and engineering. Detailed surveys, mostiy for maps on the scale of 40 chains to an inch (1 :31680), delineate soil types and land-use phases, and show the soil pattern in relation to farm boundaries and subdivisional fences.

The central importance of soil for the functioning of terrestrial systems is increasingly recognized. Critically relevant for water quality, climate control, nutrient cycling and biodiversity, soil provides more func- tions than just the basis for agricultural production. Nowadays, soil is increasingly under pressure as a limited resource for the production of food, energy and raw materials. This has led to an increasing demand for concepts assessing soil functions so that they can be adequately considered in decision-making aimed at sustainable soil management. The various soil science disciplines have progressively developed highly sophisticated methods to explore the multitude of physical, chemical and biological processes in soil.

  • A New Era of Digital Soil Mapping Across Forested Landscapes 14 Chuck Bulmera,*, David Pare´ B, Grant M
    CHAPTER A new era of digital soil mapping across forested landscapes 14 Chuck Bulmera,*, David Pare´ b, Grant M. Domkec aBC Ministry Forests Lands Natural Resource Operations Rural Development, Vernon, BC, Canada, bNatural Resources Canada, Canadian Forest Service, Laurentian Forestry Centre, Quebec, QC, Canada, cNorthern Research Station, USDA Forest Service, St. Paul, MN, United States *Corresponding author ABSTRACT Soil maps provide essential information for forest management, and a recent transformation of the map making process through digital soil mapping (DSM) is providing much improved soil information compared to what was available through traditional mapping methods. The improvements include higher resolution soil data for greater mapping extents, and incorporating a wide range of environmental factors to predict soil classes and attributes, along with a better understanding of mapping uncertainties. In this chapter, we provide a brief introduction to the concepts and methods underlying the digital soil map, outline the current state of DSM as it relates to forestry and global change, and provide some examples of how DSM can be applied to evaluate soil changes in response to multiple stressors. Throughout the chapter, we highlight the immense potential of DSM, but also describe some of the challenges that need to be overcome to truly realize this potential. Those challenges include finding ways to provide additional field data to train models and validate results, developing a group of highly skilled people with combined abilities in computational science and pedology, as well as the ongoing need to encourage communi- cation between the DSM community, land managers and decision makers whose work we believe can benefit from the new information provided by DSM.

The spatial assessment of soil functions requires maps of basic soil properties. Unfortunately, these are either missing for many regions or are not available at the desired spatial resolution or down to the required soil depth. The field-based generation of large soil datasets and conventional soil maps remains costly. Mean- while, legacy soil data and comprehensive sets of spatial environmental data are available for many regions.

  • What's Your Soil Type?
    What’s Your Soil Type? What’s Soil Made Of? Good soil is a well balanced mixture of inorganic matter, organic matter, water and air. Everything you do to manage plants depends on the soil. The soil inorganic mineral matter is determined by the parent rock of the local geology. Here in Wichita, Kansas, we have limestone & shale because this area was once a shallow inland sea that has been uplifted and then eroded by wind & water. The local soils have a high pH (alkaline a.k.a. base) and once you’re away from the river bottom land, the soil is more clay. Soil Texture Sand, silt and clay are the sizes of soil particles. Sand is the largest particle, and clay, being microscopic, is the smallest. The best soils are loams, which are a good balance between the three particle sizes. Soil texture is created by the amount each particle size mixed in a given soil. Texture is an important property of soil. It affects everything from crop productivity and nutrient requirements, to a soil’s potential for erosion. Texture determines the soil pore size, which is the space between soil particles. When you know the texture, then you know how fast a soil will absorb water, as well as, how much it will retain after the water is turned off. Jar Test Soil Amending The A jar test is a simple way to determine what type of soil you have. To conduct a jar test, you will need: A 1 quart or larger size glass jar with lid A paper or plastic bag Water A ruler 1.

The holistic study of soils requires an interdisciplinary approach involving biologists, chemists, ge- ologists, and physicists, amongst others, something that has been true from the earliest days of the field. In more recent years this list has grown to include anthropologists, economists, engineers, medical professionals, military professionals, sociologists, and even artists. This approach has been strengthened and reinforced as cur- rent research continues to use experts trained in both soil science and related fields and by the wide array of issues impacting the world that require an in-depth understanding of soils.

The topsoil size fractions were separated through wet sieving and named, respectively: macroaggregates (250–2000 µm), free microaggregates (50–250 µm), and silt + clay (< 50 µm). Protected microaggregates held within macroaggregates were extracted using a constant and continuous water flow process. We assessed the pool of phytoliths through heavy liquid separation and alkaline dissolution (Na2CO3), and we assessed the bioavailability of Si using CaCl2 extraction. As expected, NT generates larger amounts of aggregates than CT.
