I met an older farmer this week, the kind who can fix a tractor with baling twine and a prayer.
He farms the same ground his father did. Same fields, same rhythms, same chemicals.
“We spray,” he said, matter-of-fact. “But don’t worry, the rain washes it all off.”
It’s hard to argue with a father’s lessons, or with habits that kept a farm alive through lean years. You don’t start with a lecture. You start with a question: what if rain washes some of the chemicals away but doesn’t restore what matters underfoot?
Earlier this spring I drove through Ohio on the way to a farming conference, mile after mile of fields the color of gray-green stubble. It wasn’t cover crops or early growth. It was the tidy look of a recent glyphosate pass.
From the road, it reads as efficient. But tidy isn’t the same as healthy. Rain can rinse leaves. It can’t rebuild a living soil once chemistry becomes the main tool.
Soil health runs on relationships: roots feed microbes, microbes feed plants, plants feed us.
At Red Shirt Farm we choose the longer road: compost and cover crops, rotations, minimal disturbance. We try to keep the life in the soil going. That’s the farm we want to hand to the next generation, one that works with what rain can grow.
Glyphosate and rain
You’ll find glyphosate sold as Roundup in every big-box store’s gardening aisle. Steer clear.
Glyphosate is a common weed killer that kills nearly any plant it touches. It’s used on large farms and in backyards because it’s fast and familiar. In agriculture it’s used before planting, between crop rows, and sometimes as a pre-harvest “dry-down” on grains and legumes. In town, it’s the center aisle at the garden store, the one that makes every weed seem like an emergency.
Rain can remove residue from leaf surfaces. It can’t restore soil biology. Repeated use can disrupt soil life, and leaves soils more dependent on the next jug. What doesn’t bind in place often rides the next storm off the field and into the ditch. Water moves. Repair is another matter.
It even shows up in rain. In a U.S. Geological Survey study of agricultural sites in the Midwest, glyphosate was detected in 60 to 100 percent of rain samples.
If you’re a home gardener, there are better options:
Sheet-mulch beds or paths with cardboard and compost to smother weeds while feeding the soil.
Stale seedbed: prepare the soil, let the weeds sprout, then skim them off with a sharp stirrup hoe. Plant after.
Plant the gaps. Dense groundcovers like clover, thyme and alyssum outcompete weeds and feed pollinators.
Use flame weeders on hard surfaces and edges, not over wood chips or dry grass.
A yard or a field can look clean and still be biologically dead. The goal is a living system, and you can taste the difference.
How we manage pests without spraying is in Field Notes, and what grows from this ground is in the farm store.
