Graduated in Agricultural Engineering from Universidade Federal de Pelotas (1983), with a master's degree in Agricultural Engineering from Universidade Estadual de Campinas (1991) and PhD in Agricultural Engineering - University of Nebraska (1996). He is a Professor at the University of São Paulo, in the Department of Biosystems Engineering, ESALQ, in Piracicaba since 1989, where he coordinates the Precision Agriculture Laboratory and is a CNPq Researcher. He works at the interface between the area of Agricultural Machinery and Precision Agriculture, especially with crop and soil sensors, spatial variability, yield mapping and site specific application of inputs. He coordinated the Brazilian Congress of Precision Agriculture from its creation in 2004 until 2018; chaired the Brazilian Commission for Precision Agriculture - CBAP, of the Ministry of Agriculture, Livestock and Supply from its creation in 2012 to 2016 and was president of the Brazilian Association of Precision Agriculture - AsBraAP, from its foundation until 2020.

Projections of world population show that there will be a greater demand for food, fiber and energy, requiring an increase in agricultural productivity, cost reduction and sustainable use of natural resources. In addition, factors such as changes in final consumer market habits, increased incidence of extreme weather events, the longevity of the urban population and the labor shortages in…
Soil characterization is important in the establishment of agronomic practices that provide economic and environmental safe food production. Water retention, porosity, cation exchange capacity and texture are soil properties related to each other and can be used to define environments with varying yield potential. Soil samplings followed by standardized laboratory analysis are the usual m…
Crops in general respond strongly to nitrogen available in the soil. Sugar cane, traditionally burned for manual harvesting, has a nitrogen fertilization management relatively known. Nevertheless, on mechanized harvesting, without burning, its behavior is significantly changed. On cotton crop availability of nitrogen in the soil interferes on the quantity and quality of produced fibers. T…

For some agricultural crops the characterization of product quality becomes as important as the measurement of productivity. Sugarcane is an example. The crop profitability is a result association of productivity and quality. Despite the advances in productivity measurement, including the new sensors development in harvesters, quality measurement in real time is still a distant reality. T…
Mapping of the spatial variability of soil attributes through georeferenced samples and laboratory analyzes is limited by the cost and time demanded. In order to increase the density of soil sampling points, with no need for additional costs with laboratory chemical analysis, efforts are being applied to the improvement of different sensing techniques. Proximal sensing by VisNIR spectrosc…
The spatial and temporal variability are two basic and renowned concepts of precision agriculture (PA). Many studies and alternatives on the application of PA arose due to the increasing of properties and intensification of production. The LiDAR technology (Light Detection and Ranging) is one of these alternatives. This technology has its base on sensors, which can estimate distance betwe…

Since conventional sampling and laboratory soil analysis do not provide a cost-effective capability to obtain georeferenced measurements with adequate frequency to precision agriculture approaches, different sensing techniques have been attempted. Our original project is exploring "new" sensing tools (XRF, LIBS and Vis-NIR sensors) and the synergism between then to access fertility attrib…
The demand for alternative sources of energy is globally growing , propitiating an intense expansion to the Brazilian sugarcane sector that demands technologies to maximize the sugarcane production and its economical return. Precision agriculture appears as an important tool, offering among others, sensors that work with crops reflectance allowing for variable rate nitrogen fertilizatio…
