As in the mineral deficiency of a garden soil.
This is where the soil has insufficient levels of Nitrogen, Potassium and Phosphorus in particular. These are the three major nutrients required by plants for optimal health and growth, and are also known as NPK. Other minerals plants need in the soil include calcium, iron, magnesium, molybendum.
Soil may suffer from mineral deficiency for various reasons. For example, nitrogen leaches out, or is washed away through many soils over the winter months. This can be a particular problem in sandy soils which are free draining.
The easiest way to increase the minerals in your soil is to add organic matter.
