A chlorophyll meter is a compact, non-destructive instrument used to estimate chlorophyll concentration in plant leaves. It plays a critical role in modern agriculture by facilitating optimal nitrogen fertilization through accurate assessment of a crop's nutritional status, as chlorophyll levels correlate with nitrogen content, impacting leaf coloration.
Primarily utilized in the management of rice (paddy) fields, chlorophyll meters are applicable to a broad range of agricultural crops, including grains, cotton, vegetables, fruits, ornamental plants, and trees. These devices are essential for in-field live leaf measurements, aiding in fertilizer management to enhance crop quality and yield.
Chlorophyll primarily absorbs light in the blue (400-500 nm) and red (600-700 nm) regions. The chlorophyll meter exploits this property by measuring the optical density difference when exposed to red and infrared light, providing a SPAD value indicative of chlorophyll concentration.
The SPAD value, derived from optical density measurements at red (around 650 nm) and infrared (around 940 nm) wavelengths, reflects the chlorophyll's light absorption rate. This value has a strong linear correlation with actual chlorophyll concentration in leaves, serving as a reliable indicator for assessing plant health.
The application of chlorophyll meters is subject to leaf size and thickness limitations. Accurate measurements require multiple readings across different leaf sections, particularly in veined leaves, to obtain an average value that compensates for variability.
Traditional chlorophyll measurement involves chemical extraction and spectrophotometry, a destructive process requiring leaf samples to be chopped and soaked in solvents. Compared to these methods, chlorophyll meters offer a non-destructive alternative, enabling immediate in-field analysis.
Chlorophyll meters are extensively used in agriculture to assess the nutritional status of crops, such as rice, by measuring chlorophyll and β-carotene content. This facilitates timely harvesting based on nutritional value, improving crop management and yield through more precise and non-subjective assessments.
