Traditional Knowledge
Farmers used to plow, weed, and harvest by hand, making them confident that they understood the soil, the health of their crops, and the size of the harvest. Even with the coming of powered machinery, they were still confident in their traditional knowledge. However, without detailed measurements they did not always know which specific parts of the field excelled or why.
