River sand is a water-insoluble mineral and contains very few nutrients needed for plant growth. Generally speaking, the use of river sand to cultivate plants does not utilize its nutrients, but, like vermiculite, serves as a support for plant roots in soilless cultivation. During soilless cultivation, nutrient solution must be applied to supplement the nutrients needed for plant growth. When cultivating malt, sterilized river sand can be used for cultivation, and river sand can also be used as a mixed substrate to cultivate succulents.
