Logically speaking sand is also a type of soil in which belong to the 3 textural fraction know as Sand Silt and Clay. This textural fraction makes up the Soil Texture. (Sand, Loam, and Clay).

We consider a soil as sandy when it contain 70% or more sand. Clay when it contains at least 40% of Clay.

and Loam when it contain a equal amount of Sand Silt and Clay. (1/3 sand, 1/3 Clay, 1/3 Silt)

Now since sand doesn't contain any charges (+ and - charges) it wont be able to hold the nutrients needed for the plant to complete it's life cycle.

Clay and Silt on the other hand have both + and - charges which helps hold the nutrients needed.

You might ask why are both + and - charges are important. This is because all of the element needed by the plant to completes it's lifecycle has it's own charges (Try and look at it in a Periodic Table of elements).

  1. An absent of certain element the plant could not complete it's life cycle.
  2. Elements can't be replace by another element when it is absent.
  3. This element must be involve in both physiological and metabolic process of the plant.
  • Diffusion
  • Osmosis
  • Active Absorption
  • Direct Contact to the roots.

Soil texture also determine the soil structure as well as the pore spaces in the soil.

Which means that depending on the texture of the soil it could affect the water holding capacity, the ability to hold nutrients, the aeration, the Drainage, etc.

What type of soil do plants not grow well in?

Very few plants will grow in heavy clay soil and not many will grow in sand. Plants need organic material in the soil to enable the roots to penetrate and to nourish the plants, so the more humus soil contains, the better most plants will grow. Plants also do not thrive in very acid or highly alkaline soil. Most plants prefer neutral or slightly acid pH. Sne45: I think clay-like soil, nor do I think plants in sand can grow.
