Crop rotation is mostly done to avoid burning out your land (referred to as soil depletion).
It also helps in insuring against catastrophically low price on one crop or another or one particular pest or another destroying a crop.
But the weather will usually take all of your crops if it is going to be a problem. Unless you have a farm with varying terrain; some higher that the other and subject to flooding.
But there is really nothing a farmer can do to plan for the weather as far as choosing a crop. About all they can do is buy insurance.
Having experience in this arena, would you say that the farmer in this article is being silly blaming “climate change” for his woes, or is weather something understood by all farmers to be a fickle mistress regardless of cause?
