Diagnose of soil fertility properties of a representative agricultural mesoregion in the Cerrado biome as affected by land use.

In Brazil, most of cereal production is concentrated in the Cerrado which is characterized by poor soils. Thus, the soil fertility management is important for suitable use of Cerrado's soils. After 40 years of increasing use of Cerrado for agricultural purposes, this work aimed to evaluate the soil fertility of a representative area known as Triângulo Mineiro and Alto Paranaíba (TMAP) mesoregion.

Towards direct and eco-friendly analysis of plants using portable X-ray fluorescence spectrometry: A methodological approach.

The assessment of the nutritional status of plants is traditionally performed by wet-digestion methods using oven-dried and ground samples. This process requires sampling, takes time, and it is non-environmentally friendly. Agricultural and environmental science have been greatly benefited by in-field, ecofriendly methods, and real-time element measurements.
