Proximal sensors have been increasingly used for a variety of purposes worldwide, with
great interest on portable X-ray fluorescence (pXRF) spectrometry applications in Soil …

Light soils occupy 8% of the Brazilian territory and are especially expressive in the new and
last agricultural frontier in Brazil: the Matopiba region-in the states of Maranhão, Tocantins …

Soil bulk density (Db) measurement is essential to estimate soil carbon reserves. However,
field sampling, specially at depth, and direct measurement of Db is labor intensive, tedious …

Geophysical methods that allow determination of soil electrical resistivity (ρ) make estimates
of the space-time variation of soil water content (θ) viable, as well as of other important …

Soil structure, which is defined by the arrangement of the particles and the porous space
forming aggregates, is one of the most important properties of the soil. Among the biological …

The plant-available water capacity of the soil is defined as the water content between field
capacity and wilting point, and has wide practical application in planning the land use. In a …

No-till management systems tend to cause soil compaction in the early years of their
establishment. Soil compaction reduces crop production due to restrictions on root …

The soil water retention curve (SWRC) and soil hydraulic conductivity (K) are important soil
hydraulic properties. In Oxisols, the degree of microaggregation depends on the amount of …

Os solos leves ocupam cerca de 8% do território brasileiro e são epecialmente expressivos
na nova e na última fronteira agrícola do país: a região de Matopiba, nos estados do …

Soil water retention evaluation is critical for modeling water flow and solute transport in the
vadose zone. The objectives of this study were to evaluate the performance of five data …
