Data

Asset	Count	Notes
Crop calendar	5,006 entries	14 categories (vegetable, herb, fruit, flower, cover-crop, root, legume, grain, mushroom, native, medicinal, fiber, forage, sprout). Frost-anchored windows; 120 entries carry climate modifiers across 6 climate types
Companion relationships	1,004	510 beneficial, 95 antagonist, 12 mechanism categories
Growing degree days	120 models	Cultivar-specific GDD ranges, base temperatures, NOAA Climate Normals harvest prediction
Rotation families	12	Nightshades, brassicas, cucurbits, alliums, legumes, umbellifers, grasses, amaranthaceae, composites, mints, malvaceae, miscellaneous. Every calendar slug mapped.
Succession chains	33	Greens, roots, legumes, brassicas, cucurbits, herbs, flowers, cover crops. Frost-anchored phases with per-climate notes.
Pest/disease associations	506	Crop-to-pest edges with diagnostic symptoms, organic management, prevention, and regions. OMRI-listed management only.
Beneficial insects	200 entries	Predators (62), parasitoids (40), pollinators (50), decomposers (29), microbial controls (22). Prey and attractant cross-references; composite "now what?" intelligence layer with hand-authored notes for the top 40 pest slugs.
USDA hardiness zones	40,283 ZIPs	PRISM 2023 + waldoj/frostline centroids, offline lookup
Climate classifier	6 types	Maritime, mediterranean, continental, humid subtropical, arid, semi-arid
