FarmZone Amend turns lab sheets into crew-ready lime and fertilizer tickets

Open a field, lock crop targets, and convert pH, buffer pH, P, K, Ca, Mg, CEC, and base saturation into exact lime, gypsum, sulfur, and N-P-K rates—per acre and per bed—before anyone opens a bag.

Field brief

From dense soil report to spread list

FarmZone Amend is the field-amendment recipe studio for market gardeners, orchardists, pasture managers, and serious home growers who get dense soil reports and still have to decide what to spread. Create named fields with acreage or bed square-footage, sample depth, and region notes. Enter full panels—or confirm Vision-assisted capture from a paper report—then lock a crop target so live range meters flag lows and highs against published ideal bands.

Generate lime from buffer pH and target pH (calcitic vs dolomitic, CCE, split passes), build sulfur or gypsum paths with single-season safety caps, and compose N-P-K plus micronutrient blends from bagged and organic sources. Review before/after cation charts and export a printable amendment ticket with lbs/acre, grams/bed-foot, spreader notes, and incorporate timing—fully offline, no accounts, no paywall.

Core loop

Named field → soil panel → crop lock → layered recipe → crew ticket. Compare organic vs bagged sources, check safety caps, then print or share the ticket before a single bag leaves the shed.
01Open or create a named field with acreage or bed sq-ft, depth, and region notes.
02Enter lab values or confirm photo-assist capture; lock a crop target with ideal bands.
03Generate lime, gypsum, sulfur, and N-P-K rates; toggle sources; export the ticket.

Bench tools

Built like a clipboard, not a blank form

  • 01

    Named fields, not blank forms

    Save acreage or bed sq-ft, sampling depth, and region notes. Seeded libraries (tomato block, blueberry row, new pasture, orchard alley) show full tickets on first launch.

  • 02

    Full report panels + photo assist

    Enter pH, buffer pH, OM%, CEC, P, K, Ca, Mg, S, and base saturations. Optional Vision capture from a paper sheet locks only after you confirm every value.

  • 03

    Crop targets with live range meters

    Pick fruiting veg, leafy greens, brassicas, corn, alfalfa/pasture, acid berries, or tree fruit and watch meters flag nutrients against crop-specific ideal bands.

  • 04

    Lime, sulfur, gypsum with safety caps

    Buffer-pH lime math with calcitic vs dolomitic CCE, split-application hints, plus elemental sulfur or gypsum paths capped to practical single-season rates.

  • 05

    Organic vs bagged blend builder

    Match deficits to a catalog of bagged fertilizers and organics—compost, feather meal, bone meal, kelp, greensand—then toggle sources and recalculate the recipe live.

  • 06

    Before/after charts + crew tickets

    Layered pH and cation charts plus printable tickets: product list, lbs/acre, g/bed-foot, spreader passes, pre-plant vs sidedress timing, and multi-season report history offline.
