Digital soil mapping: evaluation of sampling systems for soil surveys and refinement of soil maps at lower cost using legacy data

In soil surveys, several sampling systems can be used to define the most representative sites for sample collection and description of soil profiles. In recent years, the conditioned Latin hypercube sampling system has gained prominence for soil surveys. In Brazil, most of the soil maps are at small scales and in paper format, which hinders their refinement. The objectives of this work include: (i) to compare two sampling systems by conditioned Latin hypercube to map soil classes and soil properties; (II) to retrieve information from a detailed scale soil map of a pilot watershed for its refinement, comparing two data mining tools, and validation of the new soil map; and (III) to create and validate a soil map of a much larger and similar area from the extrapolation of information extracted from the existing soil map. Two sampling systems were created by conditioned Latin hypercube and by the cost-constrained conditioned Latin hypercube. At each prospection place, soil classification and measurement of the A horizon thickness were performed. Maps were generated and validated for each sampling system, comparing the efficiency of these methods. The conditioned Latin hypercube captured greater variability of soils and properties than the cost-constrained conditioned Latin hypercube, despite the former provided greater difficulty in field work. The conditioned Latin hypercube can capture greater soil variability and the cost-constrained conditioned Latin hypercube presents great potential for use in soil surveys, especially in areas of difficult access. From an existing detailed scale soil map of a pilot watershed, topographical information for each soil class was extracted from a Digital Elevation Model and its derivatives, by two data mining tools. Maps were generated using each tool. The more accurate of these tools was used for extrapolation of soil information for a much larger and similar area and the generated map was validated. It was possible to retrieve the existing soil map information and apply it on a larger area containing similar soil forming factors, at much low financial cost. The KnowledgeMiner tool for data mining, and ArcSIE, used to create the soil map, presented better results and enabled the use of existing soil map to extract soil information and its application in similar larger areas at reduced costs, which is especially important in development countries with limited financial resources for such activities, such as Brazil.

Caracterização, gênese e uso de latossolos sob cerrado no município de Rio Paranaíba - MG

The main objective of this research was to study the morphological, physical, chemical, mineralogical and geomorphic characteristics of two soil types in the Rio Paranaíba área of Minas Gerais. Using descriptions based on current methods, the soil profile study was carried out in two trenches both two meters in depth. The landscape of this region consists of an extensive, flat plain where the Red Yellow Latosol is found. In addition, the Dusky Red Latosol is distributed on slopes between the basin of Parana-São Francisco and the plateau. Chemical analysis show that the Red Yellow Latosol presents an extremely low natural fertility and the high amounts of gibbsite indicates a highly advanced degree of weathering for this soil. Mecanization is difficult in the Dusky Red Latosol due to the steep relief. Thus, Dusky Red Latosol could be put to better use as land for pastures and perennial crops taking the necessary care to prevent erosion. The soils were classified respectively as Typic Acrustox and Acrustox according to the Soil Survey Staff (67) and were categorized as Dystrophic Red Yellow Latosol of a clayish texture, flat relief, with clayish substratum sediments and Dystrophic Dusky Red Latosol, of clayish texture, high relief, undulant substratum, with and volcanic tuffs in agreement with the criteria proposed by Bennema and Camargo (11) for the Brasilian Classification.
