英文摘要	The original rawdataset used to generate thiswork contained a number of duplicate entries roughly 7% of the total farm fields.The substantivemajority of these were from one large farm that had conducted their operations in away that caused duplication as a side effect in our data generation process. Unfortunately, as the error was in the rawdataset, its correction required a re-run of the entire data pipeline, resulting in numerous small downstreamchanges. With respect to the most important numbers, the accuracy of the classifier went down slightly from 91.5% to 91.2% measured in absolute terms but increased from 0.68 to 0.74measured by kappa.The trend in cover cropped acres grew slightly stronger, and the yield effects inmaize and soybeanmoved from0.65%to 0.71%and 0.35% to 0.29% respectively. None of the overall conclusions of thework havematerially changed.Below,we provide all changes to the applicable sections of the originalmanuscript in bold underscore (or strikethrough) where applicable, in addition tomodified versions of the corresponding figures and supplementarymaterials. © 2019 The Author(s).
