Introduction to river sand

River sand is formed by long-term collision and friction of natural stone through the force of water. Its surface is relatively smooth and its color is white to yellow. It is a kind of non-metallic ore with high impurity content

River sand composition

The composition of river sand is relatively complex. Generally speaking, the main component is quartz, which contains elements such as silica

River sand characteristics

Advantages

First, the particles of river sand are smooth and relatively clean

Second, the source of river sand is very wide, the material is convenient and the cost is low

Third, river sand has no taste, while sea sand has salt taste

Fourth, the river sand has good water permeability and air permeability

Shortcomings

First, the river sand has no nutrients

Second, river sand particles are large, easy to leak fertilizer and water, and poor fertilizer and water retention

Third, the river sand is easy to leak. Sometimes, in order to keep water for the plants, they have to water frequently, resulting in rotten roots of the plants

Suitable plants for river sand

River sand is insoluble in water and contains little nutrients for plant growth. Generally speaking, the use of river sand to cultivate plants does not use its nutrition, but, like vermiculite, as the support of plant roots in soilless cultivation. In soilless cultivation, nutrient solution should be applied to supplement the nutrients required 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 succulent plants< span>
