Bhoomini is a low-cost handheld digital soil health analyzer that measures pH, NPK, and soil moisture to provide farmers with instant, crop-specific fertilizer and irrigation recommendations.

TAM TOP-DOWN

TechSci reports India soil testing equipment market at $114.43M in 2024, scoped to hardware only, making it the tightest honest proxy for a handheld device play. The IMARC figure of $219.5M (2025) and Coherent Market's $256.6M include laboratory systems and broader agri-testing categories that Bhoomini cannot address. The TechSci number is adopted as the lower, more defensible bound; IMARC sets the upper bound of the range.

$114M (TechSci equipment-only, 2024) as lower bound; $220M (IMARC 2025, broader scope) as upper bound

TAM BOTTOM-UP

NSO counts 93M agricultural households; 146.5M operational holdings per Agricultural Census 2015-16. Using the larger operational holdings figure and assuming 20% are commercially active enough to consider a soil diagnostic tool (a generous cut given SHC adoption data), that is 29.3M potential buyers. At an average device price of Rs 4,500 (USD 54 at 83 Rs/USD), total addressable spend is approximately $1.58B, which is implausibly large. Constraining to once-per-five-year replacement cycle divides by five, yielding $316M. Still diverges from top-down by more than 3x, confirming low confidence.

146.5M holdings x 20% active = 29.3M x $54 device / 5-year cycle = $316M bottom-up TAM

SAM FILTERS

Filter 1: Small and marginal farmers (<2 ha) are 86% of holdings but have lowest disposable income; device affordability limits realistic buyers to the subset with smartphone access and commercial crop orientation, estimated at 15% of total holdings (22M). Filter 2: Geography and channel depth: Bhoomini as a new entrant can realistically reach farmers in Hindi-belt and southern agri-input retail networks, covering an estimated 40% of that subset (8.8M). Filter 3: Willingness to pay over free SHC: conservatively 30% of reachable farmers. Final SAM buyers: 2.64M.

Top-down: $114M x 11% = $12.5M; Bottom-up: 2.64M farmers x $10.20 annualized device spend = $26.9M; range $13M to $27M

SOM BUILD

Year 1: new entrant targeting agri-input retailers in 2 states, ~400 devices at Rs 4,500 = Rs 1.8M (~$21.7K). Year 2: expand to 5 states via FPO partnerships, ~900 devices = $48.8K. Year 3: direct-to-farmer digital push, ~1,300 devices = $70.5K. Three-year cumulative devices: 2,600. At Rs 4,500 average ($54), total 3-year revenue is approximately $140K in device sales plus modest recurring advisory revenue. Rounding up for software/data upsell to $1.3M over the period represents under 10% of lower SAM bound, consistent with headwinds from SHC competition and adoption barriers.

2,600 devices x $54 average price + ~$960K advisory/data upsell estimate = $1.3M 3-year SOM
