PROBLEM TO BE SOLVED: To provide a farm work support system enabling an appropriate work in a field regardless of a fertilizer concentration in the field.SOLUTION: A farm work support system 1 includes: a travel vehicle boy 11 included in a tractor 10 and traveling on a field 350； a tillage device 40 connected to the travel vehicle body 11 and for performing ground work； a fertilizer concentration sensor 230 for detecting information on the field 350； and a tablet terminal device 300 for storing work information of the tillage device 40 and field information acquired by the fertilizer concentration sensor 230. In the farm work support system, the tillage device 40 serves as a work device, the fertilizer concentration sensor 230 acquires a fertilizer concentration in the field 350 as the field information, the tablet terminal device 300 stores the fertilizer concentration acquired by the fertilizer concentration sensor 230, and a work position and a motion of the tillage device 40 are changed in accordance with the fertilizer concentration stored in the tablet terminal device 300.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】圃場での作業を、圃場の肥料濃度に関わらず適切な作業にすることのできる農作業支援システムを提供すること。【解決手段】トラクタ１０が有し、圃場３５０を走行する走行車体１１と、走行車体１１に連結され、対地作業を行う耕耘装置４０と、圃場３５０の情報を検出する肥料濃度センサ２３０と、耕耘装置４０の作業情報、及び肥料濃度センサ２３０で取得した圃場情報を記憶するタブレット端末装置３００と、を備える農作業支援システム１において、作業装置として耕耘装置４０を有し、肥料濃度センサ２３０は、圃場情報として圃場３５０の肥料濃度を取得し、タブレット端末装置３００は、肥料濃度センサ２３０で取得した肥料濃度を記憶し、タブレット端末装置３００に記憶された肥料濃度に合わせて、耕耘装置４０の作業位置や動作を変更する。【選択図】図１
