Here is an article from my local county that looks into the gains in production and efficiency farmers have made through the decades.
In 1892, federal records show, wheat farmers in California produced an average of 0.44 tons per acre.
It was impressive for the time, and Stanislaus County was part of it. One observer wrote that “from boundary to boundary it may justly be said to comprise one great grain field.”
Could farmers top this bounty? Yes, they could, and they would do so several times over in the century-plus that followed.
