چکیده

In order to measure the p hysical and structural characteristics of the plants, a detection system based on a Time of Flight laser scanner known as LIDAR (Light Detection and Ranging) has been developed. The LIDAR system i s part of a research program to contro l and optimise the d oses of pesticides applied to crops in order to reduce the environmental and economical impact of disea ses control pra ctices. The measurement system is presented, together with the first set of results corresponding to field test s carried out during the 2 004 sea son, in fruit, citr us and vineyard orcha rds. Finally, the experimental results of the manually-made and LI DAR measurements were compared, to look for useful correlations for certain crop parameters such us tree volume and leaf area index, LAI. The obtained results will be used as support for t he de cision making rel ated to the optimization o f pesticid e treatments for crop protection.

Ultrasonic and LIDAR Sensors for Electronic Canopy Characterization in Vineyards: Advances to Improve Pesticide Application Methods

Canopy characterization is a key factor to improve pesticide application methods in tree crops and vineyards. Development of quick, easy and efficient methods to determine the fundamental parameters used to characterize canopy structure is thus an important need. In this research the use of ultrasonic and LIDAR sensors have been compared with the traditional manual and destructive canopy measur...

Interactions among leguminous trees, crops and weeds in a no-till alley cropping system

Trees improve the soil quality and their rapid growth in the tropics make agroforestry systems potentially effective for establishing low-input agricultural systems in this region. This study assessed the effects of the biophysical interactions among leguminous trees, weeds, cotton and maize in an alley cropping system. The experiment comprised six treatments: Clitoria + Gliricidia; Acacia ...

NON-DESTRUCTIVE THERMAL DAMAGE CHARACTERIZATION OF CORDIERITE-MULLITE REFRACTORIES

Abstract: Refractory materials containing cordierite (2MgO.2Al2O3.5SiO2) and mullite (3Al2O3.2SiO2) are used as support in furnaces, because of their low thermal expansion properties which confer them a very good ability to thermal shock resistance. Composed of two phases presenting very different CTE (1.5–3×10-6 for cordierite and 4–6×10-6 K-1 for mullite), these materials can develop damag...
