PROBLEM TO BE SOLVED: To provide a field management device for using a plow layer depth for every field measured by a plow layer depth detector as management data for putting the management data to account of the overall work plan in the field.SOLUTION: Pieces of work data 4, 5, 6 including plow layer depth data of the field measured by a plurality of rice transplanters 1, 2, 3 in implantation work, are input to a control unit 7, a plow layer depth comparison table 18 using average plow layer depth data 15 of each field is created, then, the plow layer depth comparison table 18 is displayed on a monitor 8 in a field management device.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】耕土深さ検出装置で測定した圃場毎の耕土深さを管理データとして圃場の総合的作業計画に役立てようとすること。【解決手段】複数の田植機１，２，３で移植作業中に計測した圃場の耕土深度データを含む作業データ４，５，６を制御装置７に入力し、各圃場の平均耕土深度データ１５を用いた耕土深さ比較表１８を作成し、該耕土深さ比較表１８をモニタ８に表示する圃場管理装置とする。【選択図】図１
