- •
Soil texture was determined from its elemental composition with LIBS.
- •
Correlation between LIBS and the pipette method was > 0.85.
- •
LIBS uncertainties were below 8% for sand, silt, or clay.
- •
LIBS analysis takes less than one minute per sample.
- •
LIBS can be used to quickly build soil texture maps.
