🌾 FarmMart

1Business context

FarmMart is an agriculture services portal for farmers: live mandi (market) prices with alerts, a fertiliser calculator based on soil tests, and equipment rental booking.

Three tools in tabs: a sortable mandi price table with price alerts, a fertiliser calculator that turns soil-test levels into urea/DAP/MOP bag counts, and equipment rental with dates and day steppers.
