abstract = "Vegetation is very important in climate regulation and carbon
cycle to remove and store large amounts of carbon dioxide. This
study quantified the aerial plant biomass to obtain the carbon
stock of pastures with the aid of remote sensing at Figueira Farm,
municipality of Londrina, State of Paran{\'a}, Brazil. Five 10m
x10m plots were established with Tanzania grass and after their
free growth, five locations of 1m2 were cut to calculate biomass.
Four vegetation spectral indices were generated: SR, NDVI, EVI and
EVI2, as well as two buffers (50m and 100m), for greater coverage,
from a scene of Landsat-8/OLI from August, 2015. The statistical
analysis was performed with Pearson''s correlation and stepwise
regression. The Tanzania grass produced a mean biomass of 3.67
Mg.ha-1 and mean carbon stock of 1.83 MgC.ha-1. The mean values of
vegetation indices were 0.67 for NDVI, 0.58 for EVI, 0.54 for
EVI2, and 4.80 for SR. The average values for the 50m buffer were
0.64 for NDVI, 0.54 for EVI, 0.52 for EVI2, and 4.35 for SR. The
average values for the 100m buffer were 0.61 for NDVI, 0.51 for
EVI, 0.49 for EVI2, and 3.98 for SR. The Pearsons correlation
analysis indicated a strong negative correlation of the total
biomass of pasture with all vegetation indices and buffers values.
Stepwise regression analysis was significant for EVI (R2=0.91). It
was found that vegetation indices have great potential in estimate
the aboveground biomass, however these indices have not been
sensitive enough to eliminate the soil effects.",
