The continuous development of equipment is also very important in the earth moving procedures which require significant time and expense to achieve the so-called ＂precision agriculture＂ or rather ＂precise management of agricultural inputs＂. One of the ＂precision agricultural＂ works is the land leveling. In recent years, land leveling is done with the use of a scraper （blade） mounted on the agricultural tractor. An electronic system controls the height of the blade automatically, without any operator intervention. In this paper, the field efficiency of the tractor MF6290, of 135 Hp horsepower, is calculated with a leveling blade of 4 m width, in the land leveling of rice cultivation, and in the rotation of different crops in different land preparation conditions （initial and final slope） in the area of Thessaloniki, northern Greece. The raw data revealed that the performance of the tractor ranged from 0.402 to 0.82 lha/h, on a slope 0%, while for surfaces with different initial and final slope, it ranged from 0.107 to 0.118 ha/h.展开更多

In the traditional approach, professional competencies of a farmer comprise the ability to operate machines and technical equipment in production technologies for biological raw materials. Precision agriculture increases this range of professional competencies with the ability to use computer IT systems that are complex and, by their very nature, much differing in their content and scope from typical farming knowledge. The ergonomic problem can be brought down to determination whether the operation of IT systems in precision agriculture is adjusted to the predispositions, needs and skills of the farmers. Generally, in the IT system of precision agriculture, three phases can be differentiated： data collection, processing and application. To what extent should they be operated by the farmer, and to what extent by the IT specialist, is the problem that determines effective functioning of precision farming. The ergonomic assessment of some software for equipment operation, generation of harvesting maps and applications points to： （1） the need for standardisation in construction and operation of IT systems; （2） the division of the function-farmer and IT specialist （e.g. from an agriculture consulting institution） in the precision agriculture system.展开更多
