1. Geomorphometric tool associated with soil types and properties spatial variability at watersheds under tropical conditions
ABSTRACT The application of quantitative methods to digital soil and geomorphological mapping is becoming an increasing trend. One of these methods, Geomorphons, was developed to identify the ten most common landforms based on digital elevation models. This study aimed to make a quantitative assessment of the relationships between Geomorphons units, determin

2. Morphological Interpretation of Reflectance Spectrum (MIRS) using libraries looking towards soil classification
The search for tools to perform soil surveying faster and cheaper has led to the development of technological innovations such as remote sensing (RS) and the so-called spectral libraries in recent years. However, there are no studies which collate all the RS background to demonstrate how to use this technology for soil classification. The present study aims

3. Disponibilidade de água e de nutrientes do solo e desenvolvimento do eucalipto em uma microbacia hidrográfica no município de Pinheiro Machado - RS. / Availability of water and nutrients in the soil and the development of eucalyptus in a hydrographic microbasin in the city of Pinheiro Machado RS.
O conhecimento da distribuição dos solos permite o planejamento das atividades agrícolas de forma a maximizar a produtividade das culturas e a reduzir a degradação ambiental. Dessa forma, a reserva e a disponibilidade de água e de nutrientes para as plantas se tornam de grande importância, podendo ser avaliadas por meio de análises físicas, química

4. Variation in Heterotrophic and Autotrophic Nitrifier Populations in Relation to Nitrification in Organic Soils †
The occurrence of heterotrophic and autotrophic nitrifiers in Pahokee muck and the role of these organisms in the ecosystem were assessed by surveying their population densities under different field conditions and by observing the relationship of these populations with aerobic bacteria and soil moisture. Heterotrophic nitrifier populations varied from 2.0 �
