Deb suggests:

Let’s plant more cover crops in the west end of the big fenced-in tomato patch. The soil there needs help. While many of the tomatoes at the west end are still alive, they are mostly cherry tomatoes, of which we have plenty. We can pull them up and make plots for the cover crop of vetches, peas and drill tap radishes. To prepare the plots we can make one large square (maybe 20′ X 20′) or divide it into 4 smaller ones, (probably best) using topsoil we get from Maestas Sand and Gravel for the berms. I suggest this because we don’t want to rake the good soil we’ve created onto the berms leaving hardpan in which to plant the cover crop. Use Maestas topsoil, which really isn’t very rich, for the berms.

The jobs will be: Pulling the cherry tomato plants, saving the ripe fruit.
Plotting off 4 squares and lightly disturbing and leveling the soil to prepare it for the seeds. It’s easier to level small squares.
Getting volunteers with pickups to bring Maestas topsoil – I think 2 loads would be enough – 1/2 cubic yard for small trucks or 1 cubic yard for big ones. Maestas is on the Meadow Lake Rd, just about 100′ east of the El Cerro stop light on the right.
Wheelbarrowing the soil onto the berms.
Broadcasting the seed – best to uses rakes to make holes first.
Cover lightly with topsoil, light layer of hay, mulch stuff.
Tamp down lightly.
?Cover with light cloth to maintain moisture and heat? No danger of chickens in the fenced area.

Are there other plots where we want to put cover crops?
