Nutrient balances of sugarcane cultivation were analysed during its intensification.
- class="label">•
During 1943–1984, pastures and wetlands were replaced by sugarcane in the Cauca river valley.

The positive N balance suggests that N has been historically over applied and wasted.

K and P balances were positive in the early intensification period due to chemical fertilizers.

Later, application of sugarcane residues reduced chemical K and P fertilizers.
