Work day notes

I have fallen behind in posting updates about the progress on the farm. In the last few meetings we have: reorganized what is left of our brush piles after renting a chipper, turned our compost pile, laid out quite a few beds, planted some potatoes, lettuce, cucumbers, and peas, got rocks and concrete laid to outline some of the beds, moved some of the tomato transplants out to the greenhouse,  repaired two of the wheelbarrows, mowed parts of the field, done a lot of cleanup, set stakes to protect the new trees from pedestrians and vehicles, dug up some concrete, planted lemon balm around broken concrete in the irrigation ditch (to help stabilize it), continued work on the fencing, added a second automatic vent to our greenhouse, (with only one, the greenhouse overheated severely,) and continued the work of using up our many piles of mulch, leaves, and manure.
Our greenhouse survived the late snows earlier this week, and the tomato transplants inside are all safe. However, one of the heated frames at my house, which still held over two hundred tomato plants, malfunctioned, and we have lost over a hundred of them. Depending on what members want to do, we may buy replacements, or do without.
Then new vent opener is at the bottom of the greenhouse, on the opposite side from the existing one, to create a chimney effect.
To plant potatoes, we laid out cardboard, and built sheet mulch beds in the usual way. But we included potatoes in the bottom layers. As they grow, we will be adding more mulch, instead of trenching and hilling. We used some actual seed potatoes, (which are less likely to contain disease organisms that can kill or stunt the crop) but the price was too high, so most of them are just organic potatoes from the store. After much searching online, it seemed that most people can get away with doing this. Also, a disease can still show up in other ways, even with certified seed potatoes. A disease showing up is much less of a disaster for us then for a commercial farmer, who is depending on potatoes.
