Leaf area index (LAI) in fertilised plots in the Central Amazon, 2017-2018

The dataset contains the leaf area index (LAI) (m2/ m2 ) collected with the LAI-2200 C (plant canopy analyzer), that was computed with 5, 4 and 3 rings using the FV2200 software. Additionally, it has the x and y coordinates (m) of the points collected inside the plots and the time of collection (hour: min: sec). This research was collected in a field site approximately 80 km north of Manaus, in the state of Amazonas, Brasil. The campaigns were carried out in October 2017, March 2018, August 2018 and October 2018. Full details about this dataset can be found at https://doi.org/10.5285/6e70665f-b558-4949-b42a-49fbaec7e7cc

Statement
The points were collected in 36 points inside the plot with the LAI -2200 C (plant canopy analyzer) . The data were collected from 6 am to 5 pm, avoiding recording data between 12:00 and 2:00 pm, to avoid direct sun. The LAI-2200 C requires an above canopy reading for reference, and in our case the optical sensor was placed in a clearing to log automatically while the user operator collected manually below the canopy. The sensors were always placed in the same compass direction ( both in the west in the morning and east in the afternoon). We used a view cap of 45 °C in the sensors to remove the operator from the sensor’s view. The sensors were matched before the data collection, as recommended in the manual. The row data were analysed using the FV2200 software, where LAI was obtained (m2 one sided foliage area/ m2 ground area), that was computed with 5, 4 and 3 rings, and each ring respond over a different range of zenith angles.
