soilassessment (version 0.3.0)

Soil Health Assessment Models for Assessing Soil Conditions and Suitability

Description

Soil health assessment builds information to improve decision in soil management. It facilitates assessment of soil conditions for crop suitability [such as those given by FAO ], groundwater recharge, fertility, erosion, salinization [], carbon sequestration, irrigation potential, and status of soil resources.
