A thing that enriches something is enrichment. For example

• A reading enrichment program improves education.
• When vitamins or nutrients are added to food, that's enrichment because it makes the food healthier.

Enrichment can also mean the state of being enriched. For example:

• Manure contains plant essential nutrients, but overuse of manure on agricultural land can cause nutrient enrichment in soils, consequently leading to groundwater eutrophication.
• Native North American grasses develop an extensive root system, allowing for greater enrichment of the soil.

Fertility refers to the quality of being able to fertilize, so it can have the following meanings:

• the quality of producing a large number of good quality crops
• the quality of being able to produce young or fruit:
• the quality of producing a lot of unusual and interesting ideas 

Example sentences:
