Quick field use

LRN Field Cards

Use these when standing in the field. They are deliberately simple: observe first, make one low-risk correction, then check the response.

Bare soil

Cover with dry organic mulch or living cover. Do not bury stems. Check moisture after two days.

Pause irrigation, open drainage paths, thin wet mulch, and check for sour smell or root rot.

Water slowly, increase surface cover, reduce transplanting or pruning, and protect from afternoon heat.

Check water first, then roots, then pests, then pH/salts/nutrients. Do not guess with strong inputs.

Avoid deep digging around roots. Use cover roots, organic matter, and gradual biological loosening where possible.

Remove before it dominates. Keep functional diversity, not uncontrolled growth.

Add mature compost lightly, keep mulch moist, retain roots, and avoid chemical or salt shocks.

Check crop stress, excess nitrogen, lack of diversity, and humid overcrowding before spraying.

Keep mulch away from direct stem contact.
Do not add fresh wet organic matter against roots without aeration.
Do not scale an untested practice across the whole farm.
Use soil, water, or tissue testing where commercial decisions depend on diagnosis.
