Non-destructive measurement of plant chlorophyll to optimise fertiliser usage
Improve yeild whilst reducing cost and environmental contamination.
The SPAD-502Plus enables quick, easy measurement of the chlorophyll content of plant leaves without damaging the leaf. Chlorophyll content is one indicator of plant health and can be used to optimise the timing and quantity of applying additional fertilizer to provide larger crop yields of higher quality with lower environmental load.
Some studies show that application of SPAD data contributed to reduction in nitrogen fertilizer usage ranging from 20% to 40%, depending on crop type and environmental conditions, while maintaining or even enhancing yields. This reduces the disease and environmental contamination caused by excess fertilisation.
Principal Applications
Monitoring of growth and health of plants
The SPAD-502Plus can be used to monitor the growth and health status of a wide variety of agricultural products, including wheat, rice, corn, cotton, etc.
Nitrogen fertilization optimization
The SPAD-502Plus can be used for determining when and how much nitrogen fertilizer should be provided to plants. Optimizing fertilization in this way leads to not only greater yields of higher quality, but also results in less over-fertilization, reducing environmental contamination due to the leaching of excess fertilizer into the soil and underground water.
