Geography the process in which nutrients are dissolved in water and percolate downward below the root zone of crops is called:

Nutrient Leaching

Leaching is the process where dissolved nutrients in the soil profile moves downward with percolating water. It is the loss of water-soluble plant nutrients from the soil. The nutrients that seep through the rooting zone may be recycled if roots grow deeper.
