It's interesting - and a little disappointing - that a lot of what was once common knowledge to farmers has been lost.
The appreciation of the seasonality of the local fruit supply has been diminished by the year-round availability of produce at the grocery store. Strawberries ripen in May and June. Tomatoes are early if they're ready in July. I would guess most of us don't realize this.
There are also the tidbits of knowledge that "in the good old days" could determine if a market farmer made a profit, such as what it means to have a significant presence of crimson clover in the pasture (hint: it's an imbalance of a commonly known nutrient/chemical).
We think it's wisdom to consider how to find this old knowledge and apply it on the farm.
