Bloom / pH Test Paper


Soil acidity is an important factor affecting global food production. By regularly detecting the soil pH, the soil acidification and salinization can be effectively prevented and treated in time.
For economically backward areas, the conventional soil pH testing process is cumbersome and complicated, requiring some professional knowledge and experimental equipment, which is not conducive to forming good feedback. Based on user experience, I tailored to local conditions and devoted myself to designing an environmentally friendly, simple and efficient pH test product that meets farmers' perception.
