Soil Light / Farmland soil nutrient detection equipment

Soil Light
Soil Light

In many places, farmers who lack professional agricultural knowledge always apply too much chemical fertilizer to promote the crops grow. This is especially true for novice farmers. As a result, the soil quality is getting worse.

This concept aims to prompt farmers to apply chemical fertilizer rationally. By measuring the content of nitrogen(N), phosphorus(P) and potassium(K) in soil, the device will emit different colors of light to show soil fertility: green( Rich ), red( Poor ) and yellow ( Over nutrient ). The colors will guide farmers how to
treat the soil.

It may be a good way to prompt them to use organic fertilizer.
