Within the EU project ISAFRUIT (www.isqfruit.org) a Crop Adapted Application System (CASA) was developed to ensure precise, efficient and safe spray application in orchards, according to actual needs of the crop and with respect to the environment. The CASA system consists of three sub-systems: (i) Crop Health Sensor (CHS) identifying heath status of fruit crops, (ii) Crop Identification System (CIS) identifying the tree canopy size and density, (iii) Environmentally Dependent Application System (EDAS) identifying environmental circumstances during spray applications. In order to protect sensitive areas within the orchards surroundings (e.g. surface water, melioration wells, public sites) the spray application parameters such as droplet size and air flow velocity need to be carefully adjusted taking into account wind direction and velocity as well as position of sprayer in relation to these areas. On EDAS sprayer wind velocity and direction is measured with an ultrasonic anemometer, and sprayer position is determined by GPS. Nozzles are altered automatically depending on wind situation to adjust droplet size according to drift risk level. A novel fan construction allows the supporting airflow to the left and right hand sections of the sprayer to be adjusted independently. This adjustment is done automatically depending on the wind situation and sprayer position.

This paper presents in its first part the basis of interventionism in agriculture. It presents currently existing system of support for organic orchards in Poland and EU and proposed changes. In the empirical part, the paper presents the economical situation of Polish fruit-growing farms in respect to other farms according to FADN data (Farm Accountancy Data Network). It has been ascertained that agri-environmental payments answer for 32% of those farms’ income, which is an amount approximate to other farm types. A proposition of change in organic orchard farms’ subsidies has no basis in regard to economical situation of those farms and can cause unfavorable fallout for them and their surroundings. Because of many flaws in the system of these subsidies, it is needful to intensify the control by Agency for Restructuring and Modernisation of Agriculture (ARMA)
