In-field monitoring is a critically important component of the biological approach.
Proactive plant management involves precision nutrition to achieve the plant resilience that reduces the need for chemical intervention. Refractometers, sap pH meters, nitrate and potassium meters are tools that monitor the sap of the plant to determine nutrient requirements. However, the first step in this monitoring process is the successful extraction of the sap from the leaf. This device is manufactured in the NTS workshop and it has proven very popular amongst growers already using the technology. These adapted vice grips are of particular benefit as the extractor is more durable than a basic garlic crusher.
