Integrated soil fertility management is becoming increasingly important for all crops in the wake of declining soil fertility in many Tropical countries. It requires a complex of approaches that need to be properly and judiciously coordinated for profitability and sustainability. Using the emerging knowledge of crop modeling, farm input decisions are made easier and more accurate. This book describes an Arabica coffee yield model, developed by calibrating a generic model QUEFTS to the coffee ecosystem of Northern Tanzania. It is especially useful to elite coffee farmers, agronomists, extensionists and academicians interested in the field of crop modeling.
