WebNot everyone knows that plant roots have symbiotic relationships with certain types of fungi. These mycorrhizae help the plant absorb nutrients from the soil that are otherwise difficult to obtain and often provide some protection against soil-borne diseases. In exchange the plant suppliesfood to the fungus. To learn more about mycorrhizae, read this article... WebSoil texture refers to the proportions of sand (2.0 – 0.05 mm in diameter), silt (0.05 – 0.002 mm), and clay (less than 0.002 mm). The relative proportions determine the textural class.
