| Summary: | Knowing chemical soil properties might be determinant in crop management and total yield
production. Traditional soil properties estimation approaches are time-consuming and require
complex lab setups, refraining farmers from promptly taking steps towards optimal practices in
their crops. Soil properties estimation from its spectral signals, vis-NIRS, emerged as a lowcost,
non-invasive, and non-destructive alternative. Current approaches use mathematical and
statistical techniques, avoiding machine learning frameworks. This proposal uses vis-NIRS in
sugarcane soils and machine learning techniques such as three regression and six classification
methods. The scope is to assess performance in predicting and inferring categories of common
soil properties (pH, soil organic matter OM, Ca, Na, K, and Mg), evaluated by the most common
metrics. We use regression to estimate properties and classification to assess soil property status.
In both cases, we achieved comparable performance on similar setups reported in the literature
for property estimation for pH(R2=0.8, =0.89), OM(R2=0.37, =0.63), Ca(R2=0.54, =0.74),
Mg(R2=0.44, =0.66) in the validation set. |
