Rapid Monitoring of Organic Foliar Fertilizer Treatments on Organic Spelt by a Portable SPAD Meter and Field Spectroscopy

Summary

Remote sensing techniques are widely used for farming applications but are less widespread in the organic sector. This technique offers great perspective for organic farms as field scale spectroscopy could provide rapid monitoring of nutrient imbalances or stresses and the efficiency of organic foliar fertilizer treatments. One of our objectives is to decrease time and budget currently needed for destructive chemical analysis and increase the accuracy of on-site and quasi-real-time analysis of major constitutes.
