Injectors are an important component of irrigation systems in greenhouses and nurseries. Regular inspection of proper functioning is needed to ensure that injectors are delivering the intended concentration of fertilizer to the crop.
Inspect injectors functionality at least once before each growing season to prevent nutrient disorders caused by excessive or insufficient nutrients.
A recent e-GRO alert outlines two methods you can use to determine if your fertilizer injectors are working properly. The first method — the flow method — calculates the actual injection ratio, while the second method — the EC method — estimates the final EC of the fertilizer solution. Check out the e-GRO alert here to learn more about each method.
