The problem
Smallholders, market gardeners and home gardeners fertilise blindly: they waste fertiliser, damage their soil and get disappointing yields.
The solution
A simple sampling kit sent to the client, analysed by a partner lab, with a clear report and amendment doses suited to the crop.
Your customers
Small farms, market gardeners, farming cooperatives, community gardens, nurseries and keen home vegetable growers.
How you make money
25 to 60 € per analysed kit with advice, 15 to 30 % discount for cooperatives ordering in volume.
Competition
Agricultural labs selling direct, often free advisers from fertiliser sellers, cheap test kits with no interpretation.
Who has an edge
An agronomist or farm technician who turns figures into practical recommendations and speaks farmers' language wins the trust of cooperatives.
The risks
Shipping costs, dependence on the partner lab, small producers' low willingness to pay, seasonal orders.
The first 3 steps
- Negotiate a wholesale rate with an accredited soil lab
- Design the kit and an illustrated sampling guide
- Test with ten producers from a local cooperative
How the numbers are calculated
Example in a high-income eurozone country, at month 12: revenue €4,600 − costs €3,200 = €1,400 net per month. Revenue: 115 kits analyzed × €40. Costs: lab tests, kits and postage, advertising, software, social contributions. For other countries, Mundyo adjusts the starting budget to the price level (World Bank) and the income to prices and customers' purchasing power, then converts at the day's exchange rate.
