1. Caliming: A Decision-Support Tool for Soil Liming Recommendations

Soil acidity is one of the main limiting factors for crop production in tropical regions. In this context, liming stands out as the most efficient strategy for correcting soil acidity, promoting pH increase, neutralization of toxic aluminum, and the supply of calcium (Ca) and magnesium (Mg) to plants. Several methods for calculating lime requirement have been developed over time, ranging from classical approaches consolidated in official recommendation handbooks to more recent methods, such as...
