You know, it’s amazing how when you think you know how something works, you stop paying attention. Whenever the subject comes up in a book or whatever, the brain just turns off and says, “I already know this, I don’t have to pay attention any more.”
An example of this has come up this week in regards to the wheat project. I’ve been thinking a lot about my little 115 square foot plot and all the weeding I’ve had to do. If it took me 2 hours to weed 115 sq. ft., that would mean it would take me 758 hours (63 12-hour days) to weed an acre.
I’ll admit that I’m slow and that this is the first time in my life that I’ve really done this, so with the sort of practice makes perfect that you get from doing a job all your life let’s say that you could cut that time down by a factor of five (which is probably generous). Even then it’s taking you two weeks to weed an acre that will then need to be re-weeded after a one or two week’s worth of time. That means that one person would be continually weeding a half or a full acre.
So during the season, a family of four (ages 10+) would be doing little all day but weeding 3 acres. That does not pass a reality check. Or it just barely does if you take the few acreage figures in the polyptychs, and cut them in half, figuring them to be fallow. But only barely. And even though it may have been possible, that doesn’t mean it was done or that it even needed to be done.
I could also be doing things wrong. In an effort to save the wheat and the newspaper’s integrity, I have not been using a trowel or other tool to try and get out the weeds’ roots. This is certainly making me weed more often, but since the newspaper technique isn’t historically accurate, the problem remains, probably on a larger scale since the newspaper is actually working in large areas.
Let’s go back to my initial paragraph. I’m not a farmer, nor have I ever spent any time on a farm. I have always known that fields get plowed. I know that the scratch plow used in the Mediterranean world was unsuitable for the heavy soils of northern Europe. I know that in the second-half of the first millennium AD a newer, iron-shod or iron-constructed plow was invented and revolutionized farming in the north. But I never really thought about what that meant to the ground.
It’s particularly funny/odd/disconcerting because I’ve just finished re-reading Medieval Technology and Social Change and it has my highlights in the section on plowing, so I really have no excuse for not having internalized this information.
I know that seeds need to go in the ground to grow. So I figured that was what a plow did -- made furrows in the ground for seeds to go in. But, as I am discovering in my own back yard, it’s not that easy. What about the wild grasses and weeds that are already there? Surely you’re not pulling those out by hand?
After a little bit of research, I have been educated as to what a heavy plow with a moldboard really does. And I will discuss that, tomorrow.
