Rotational Grazing API

healthy 4,306 Subscribers

Rotational-grazing maths as an API, computed locally and deterministically — the animal-unit, grazing-day and acreage numbers a rancher or homesteader moves a herd by. It all hangs on the animal unit: a 1000-pound cow eating about 26 pounds of dry matter a day. The animalunits endpoint converts a mixed herd to that common basis — a cow is 1.0 AU, a cow-calf pair 1.3, a horse 1.25, a sheep 0.2, a goat 0.17 — so ten cows and fifty sheep are 20 AU demanding 520 pounds of forage a day; pass a weight instead and it scales by weight ÷ 1000. The days endpoint works out how long a paddock lasts: grazing days = (acres × forage per acre × utilization) ÷ (animal units × 26), where the classic “take half, leave half” puts utilization near 50 %, so five acres yielding 3,000 lb at 50 % feeds 10 AU for about 29 days. The acres endpoint sizes the paddock the other way — acres = (AU × 26 × days) ÷ (forage × utilization) — so 20 AU for a 30-day move needs about 10.4 acres. Everything is computed locally and deterministically, so it is instant and private. Ideal for ranching, regenerative-agriculture, homesteading and farm-management app developers, paddock-planner and stocking-rate tools, and grazing-chart software. Pure local computation — no key, no third-party service, instant. US units; forage yield varies with season — measure it. Live, nothing stored. 3 compute endpoints.

Animal Gestation API

Animal gestation and egg-incubation date maths as an API, computed locally and deterministically — the breeding and hatch calendar a farmer, breeder or vet works to. The gestation endpoint takes a species and a breeding date and returns the expected due date with the normal early-to-late window: due date = breeding date + the species' average gestation, so a cow bred on the 1st of January (283 days) calves around the 11th of October, a dog (63 days) whelps nine weeks later, a goat 150 days, a horse 340, a pig 114 — dozens of species from rabbit to camel to elephant, with an override for your own herd average. Give a target birth date instead and it works backwards to the date to breed. The incubation endpoint does the same for poultry and birds — chicken 21 days, duck 28, goose 30, quail 18, ostrich 42 and more — returning the hatch date, the lockdown date (stop turning and raise humidity ~3 days before hatch) and the day-7 and day-14 candling dates. Date arithmetic is exact, including leap years. Everything is computed locally and deterministically, so it is instant and private. Ideal for livestock, breeding, veterinary, farm-management and hatchery app developers, gestation-calculator and breeding-calendar tools, and agricultural education. Pure local computation — no key, no third-party service, instant. Dates as YYYY-MM-DD. Live, nothing stored. 2 compute endpoints. Averages, not a veterinary prediction.

Grain Bin API

Grain-bin storage maths as an API, computed locally and deterministically — the bushel and weight numbers a farmer or elevator sizes storage by. The bushels endpoint measures a round bin: floor area × grain depth gives the cubic feet, and a cubic foot holds about 0.8036 bushels, so an 18-foot bin filled 20 feet level holds roughly 4,090 bushels — and grain heaped to a peak adds a cone of (1/3) × floor area × peak height, so a 4-foot peak adds about 270 more. The weight endpoint converts bushels to weight by the crop’s standard test weight — corn and sorghum at 56 pounds a bushel, wheat and soybeans 60, oats 32, barley 48 — so those 4,090 bushels of corn weigh 229,040 pounds, about 114.5 US tons or 104 tonnes; pass a measured test weight for light or heavy grain. Everything is computed locally and deterministically, so it is instant and private. Ideal for agriculture, grain-elevator, farm-management and ag-tech app developers, storage-capacity and inventory tools, and harvest software. Pure local computation — no key, no third-party service, instant. US units (feet, bushels, pounds). Live, nothing stored. 2 compute endpoints.

Plant Spacing API

Plant-spacing and planting-density maths as an API, computed locally and deterministically. The grid endpoint works out how many plants fill an area in a square (rectangular) layout: from a spacing (one value, or separate row and in-row spacings) and either an area or a length and width, it returns the planting density per square metre, square foot, 1,000 ft², acre and hectare, an area-based plant estimate, and — when you give length and width — an exact edge-inclusive grid count with the number of rows and plants per row. The triangular endpoint does the same for an offset (hexagonal) layout, where rows sit spacing × √3/2 apart and fit about 15.47 % more plants than a square grid at the same spacing, and it reports the gain. The density endpoint converts a spacing into a planting density in several units, or works in reverse: give a number of plants and an area and it recommends the spacing that fills it. Lengths accept millimetres, centimetres, metres, inches or feet; area accepts m², ft², acres or hectares. Everything is computed locally and deterministically, so it is instant and private. Ideal for gardening and landscaping apps, agriculture and horticulture tools, nursery and farm planners, and reforestation calculators. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is planting layout and density; for fertilizer application rates use a fertilizer API and for mulch, soil and gravel quantities use a landscaping API.

Fertilizer Calculator API

Fertilizer maths as an API, computed locally and deterministically. The rate endpoint works out how much fertilizer product to apply to hit a target nitrogen rate over an area: from the N-P-K analysis (such as 10-10-10 or 20-5-10), a target pounds of nitrogen per 1000 ft² (or per 100 m²) and the area, it returns the product weight and the pounds of nitrogen, phosphate and potash applied. The nutrients endpoint reports the pounds of nitrogen, P₂O₅ and K₂O — and the elemental phosphorus and potassium — in a bag of a given weight and analysis. The coverage endpoint works out how much area a bag covers at a target nitrogen rate. N-P-K are percent by weight; phosphorus is reported as P₂O₅ and potassium as K₂O following the label convention, with the elemental amounts alongside (P₂O₅ × 0.4364, K₂O × 0.8301). Everything is computed locally and deterministically, so it is instant and private. Ideal for lawn-care and gardening apps, agriculture and turf tools, and landscaping and quoting software. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is fertilizer rate maths; for mulch, gravel and topsoil quantities use a landscaping API.
