Regular monitoring of nutrient levels of nitrate (NO3-), potassium (K+) and calcium (Ca2+) in plant stems, soil solution, irrigation water and drainage water not only results in good yields and fruit quality, but also reduces fertilizer costs and mitigates environmental hazards. Pocket testers are the ideal testing devices for this, as they measure samples directly and provide results in just a few seconds, allowing growers to identify and correct nutrient deficiencies or excesses immediately.
