I’m suspicious of organic fertilizer

I rotate my “crops,” alternating legumes (which fix nitrogen in soil) with other plants like tomatoes, peppers and squash (which suck it out). But that alone is not enough to replace nutrients used up in a season. My garden is a fenced collection of 4×4 or 4×8 boxes of untreated wood that look like square foot gardens (SFG) but are not exactly. It’s fenced because these adorable dogs love to eat vegetables, particularly green beans:

In case you’re wondering, the fence is 16′ x 48′ and cost about $500 in material but $0 in labor. We built it 3 years ago with the help of EG, his 3 cousins and my sister-in-law so it’s about paid for itself.

There’s a lot to be said for SFGs but they are basically container gardens, requiring a yearly investment in growing medium. My soil, if you want to call it that, blows. So I require seasonal infusions of soil amendments and nutrients, as well as some growing medium, but I think it’s inefficient to start with a fresh new load of dirt every year. Even if I weren’t such a tightwad, Metal Pig would see the expense on my spreadsheet and estimate the cucumbers’ worth at about $5 each.

But the headline says I’m suspicious of organic fert and compost, which is true. The first thing I think of when I see labels like “organic” or “all natural” is slaughterhouse waste. You might argue it’s a good use of waste, and I don’t really want to focus on that subject, but I’d rather avoid growing with animal parts if I can. There is a mushroom farm I can drive to and get a trailer load of compost that consists only of mushroom fragments and the wood shavings they’re grown in, and it’s been great for mixing with vermiculite and the existing crappy soil as a growing medium. I’ve also sucked it up and gotten city compost, which is made from stuff my fellow townspeople discard and I’m pretty sure that includes bones from chicken wings and other body parts, but it’s heavy on the nitrogen. I probably won’t do it again but I support the city’s composting program. Throughout the season I’ve added alfalfa meal, cottonseed meal, something called Texas green sand and compost tea. It’s been tempting to just use something made in a lab like Miracle Grow though.

First round

Today I planted 70 seeds in little Jiffy pucks puffed up with water. It’s not the first time. I’ve been growing heirloom vegetables for 12 years and I’m starting to get the hang of it. Previously I’ve put 3 seeds in each, in case they didn’t all germinate, which is Mel Bartholomew’s instructions. But he snips 2 of the 3 if they all germinate. What has happened is usually all sprout and I can’t bring myself to cull two of them. So I’d scramble to find room for them all both inside and out in the garden, like a hoarder, although I’d let a few select people adopt some. This time I put one seed in each cell. If one doesn’t sprout in a week, I’ll replace it.

Food I grow and what it costs

Here in Colorado, suburban agriculture can be considered kind of a luxury. The soil, without amendment and nutrients, is worthless for growing those plump, colorful vegetables you see at farmers’ markets. It can go for months without raining in the summer or snow and flood in the spring and fall. Daytime temperatures can be double the nighttime lows.

It’s possible to grow a lot of food in a small space without using an unreasonable amount of water or other resources. This year I’m tracking the expenses as accurately as I can and will calculate or estimate the return on my efforts as I pick them. I grow a lot of beans, which are eaten fresh and dried, and the ornamental-looking plants produce a lot of enjoyment and nutrition in little space. Tomatoes and other nightshades are not so easy. In the past I’ve only weighed tomatoes, a good yield for one summer being 200 pounds. You could say that’s almost a thousand bucks worth of food when you consider that these types of heirloom fruits cost $4-$5 at markets (if you can find them). But that’s only a legitimate return if you sell them or would normally buy 200 pounds of heirloom tomatoes from August to October. I make damn sure we eat, share and preserve all of them, and it’s worth it. To me. But this year I’m going to look at the actual numbers and calculate some hard, cold figures. I’m not entering time as an expense, even though time is money, because I love gardening. So it’s not billable time unless I skip work to do it.
