Manual Plant Sap Blueberry Sampling Services Brochure

Take the following steps into account when collecting leaf samples: Avoid the outer rows of the greenhouse or field. Also avoid the first and last 10 meters of a row. Sample leaves with an average leaf quality. Sample abnormal plants with e.g. deficiency symptoms separately. Might a deficiency be present in the young or old leaves of the total crop, then sample these leaves regularly as a young or old leaf sample. Take into account the sunny and shady side of the plant. Always consistently sample the same side.
