Nothing comes in a bag.
Fertility is grown on the property. It takes a little longer the first year and it pays every year after.
Cover crops
Every bed that isn't growing food is growing a cover: oats and peas in the shoulder seasons, buckwheat in the summer gaps, winter rye going into fall. They hold the soil, smother weeds, fix nitrogen, and get turned in before the next planting.
Green manure
A crop grown to be cut and turned back in. It's the cheapest fertilizer there is, and the one that also feeds the life in the soil, which is what makes the difference in year three.
Compost
One central system takes everything the property produces: garden cutbacks, kitchen scraps, and the fall leaves, on a continual turning rhythm. In late fall the finished compost goes over the beds with a shredded-leaf mat on top. It reads clean, keeps the roots fed through winter, and buffers the temperature swings.
On a property with big oaks the system runs longer: oak leaves are acidic and slow, so they get shredded, mixed with greens, and turned more often. It works; it takes a season more.
Monitoring
Remote sensors in the piles report temperature and humidity to a dashboard you can check from your phone, so we know when a pile is cooking and when it has stalled. Here is a live one.
Soil testing before amending
A test before anything is added. Most beds want organic matter, not lime; the test says which, and it saves buying the wrong thing.
Deer
Fencing where the pressure says so, a repellent rotation elsewhere, and crops the deer skip on the outside rows. A garden the deer eat is not a garden.
