Soil Fertility

Soil Fertility

There are eight varieties of soil occurring in different locations throughout the world. These soils range from very fertile, providing a 20% boost to all fertilizers applied to it, and to all nutrients recharged by crops, to very poor, providing 20% less than typical soil.

Soil quality only impacts the effectiveness of fertilizers; unfertilized crops grow at the same rate regardless of what soil they are planted in. While nutrients can be consumed by crops, soil quality is not degraded by subsequent plantings.

The following pages outline each soil type.

Entisol

Entisol is the most common soil type, found throughout the world. It is a normal quality soil, receiving no bonus nutrients.

Andisol

Andisol is found in volcanic regions. It is a high quality soil, receiving 10% bonus nutrients.

Fluvisol

Fluvisol is found along rivers in regions with wet and dry seasons. It is a high quality soil, receiving 10% bonus nutrients.

Alfisol

Alfisol is found in temperate broadleaf forests. It is a high quality soil, receiving 10% bonus nutrients.

Mollisol

Mollisol is found in cold grasslands. It is a very high quality soil, receiving 20% bonus nutrients.

Podzol

Podzol is found in conifer forests. It is a poor quality soil, receiving 10% less nutrients.

Aridisol

Aridisol is found in dry regions. It is a poor quality soil, receiving 10% less nutrients.

Oxisol

Oxisol is found in wet tropical regions. It is a very poor quality soil, receiving 20% less nutrients.
