Thanks a lot for sharing, commenting, subscribing and thumbs up.The concept of timeliness recognizes that there is an optimum time to perform certain crop production operations from planting through to harvesting. If one or more of these operations is performed too early or too late, a timeliness penalty is likely to accrue, that is, yield and/or the quality of the crop is diminished, yielding a lower price to the farmer. For example, the ideal time to harvest grain is when the crop is ripe and the moisture is low (see also, Maintaining Working Conditions and Operation of Machinery).Thus, huge savings in labor have accrued from engine-driven mechanization systems in the developed world, which in turn have been rapidly followed by rural depopulation. The societal impact of rural depopulation has not been adequately addressed.
