“…The first is where the spray angle is measured near the nozzle tip. In this method, the spray angle can be measured directly by using a protractor (usually with the help of illuminating the spray fan and dark background) as mentioned in (Bateman, 2004); (Ghasemzadeh & Humburg, 2016), or it can be measured by capturing images of the spray fan and then by using a protractor with the images as mentioned in (Liljedahl, 1971); and Juslin, Antikainen, Merkku, & Yliruusi (1995) who used a geometric triangle and original size slides projected on the screen. It can be measured also with the assistance of image processing software after defining the spray angle between a two manually drawn lines of the two outer edges of the spray fan near the nozzle tip (Bai, 2014;Roşu, Cǎsǎndroiu, Matache, Vlǎduţ, & Pruteanu, 2018;Wang, Dorr, Khashehchi, & He, 2015;Zhang, Wang, & Thierstein, 1994) and Laryea & No (2004) who investigated pressure-swirl nozzle.…”

EU forestry does not currently have automatic planters, hence the project proposes to develop an innovative technology in which the key role will be played by an autonomous planter designed for establishing forest cultures and afforestation of former farmland and reclaimed areas with the use of seedlings with a covered root system (grown in container nurseries). The device will have a self-levelling traction system, a control system with a satellite navigation module to support autonomous navigation and planting site selection, a mechanism of planting spot preparation, a planting unit, an intelligent robotic arm to feed seedlings from containers to the planting unit according to a given algorithm, a container storage unit with an automated feeder, a drive unit with an electro-hydraulic control system, a control module, and a wireless remote control system. The autonomous planter will significantly reduce the cost and machine inputs during establishing forest cultures and afforestation of former farmland and reclaimed areas with the use of seedlings with a covered root system, and thus perfectly fits into the assumptions of agriculture 4.0.

“…An increase in spray liquid viscosity results in the formation of larger droplets (Liljedahl, 1971). However, Haq et al (1983) found that increasing the spray solution viscosity by adding glycerol to water either had little effect on droplet size or increased the percentage of drops less than lOOjLtm in diameter.…”
