Abstract
They refer to the results of a multidiscipline search into the sectors Agricultural Mechanics and Rural Buildings. By means of the Arcview software has been realized a G.I.S. in order to correlate the geo-related data about of the administrative towns limits with the following operational parameters in the Province of Bari: total olive tree area; volumes of vegetable waters produced; requirement of nitrogen and potassium by the soil; nitrogen and potassium furnished to the soil by use vegetable waters. The analysis of the achieved maps has underlined a clench correlation between the total olive tree area and total olive mill area, and the availability of the same total olive tree area to the controlled spreading of the vegetable waters produced, according to the agronomic and the normative needs. Than, dimensional and constructive standards for tanktruks specifically dedicated to the spreading on the soil of these wastewaters have been defined and a prototype have been designed and built. The machine has been tested in field, underlining operational specific conditions for the distribution through olive trees and, also frequent events in which the distributed volume overcame the limits impose by law. Than, to solve it, an “recycle DPA system” has been studied and tested in field. The answer-times of the system always result lower to 1 s, while the sag-times has resulted very rapid in the conditions of more frequent work. Yet, critical operative of the adjustment system have been located; these, substantially, happen when the planned values of the work-width and of the volume to dispense, as well as those measured of the feed-speed; they doesn't consent a proportionate setting of the flow disbursed from the bar.
