Minerals Found in Soil: Primary and Secondary
The types of weathering that take place within a region have a major influence on soil composition and texture. For example, in a warm climate, where chemical weathering dominates, soils tend to be richer in clay. Soil scientists describe soil texture in terms of the relative proportions of sand, silt, and clay, as shown in Figure 5.14.the primary minerals For steady, healthy growth, plants need a constant, well-balanced supply of these three minerals. The amount your plants use of each primary nutrient varies during their growth cycle – from seedling to leafy growth to flowering – but all are necessary throughout plants' lives.
