C, h, o, p, k, n, s, ca, fe, mg. -- texture is the relative amount of various sizes of soil particles. -- composition is the relative amounts of inorganic and organic compounds. Soil is the place where much of the plant nutrients occur. Soil is made up of particles derived from the breakdown of rocks (minerals) along with organic material (humus). Two aspects of soil the texture and composition are important for plant growth. Some of the nutrients are needed in large quantities (>1% of the plant"s dry weight), these are the macronutrients (see table 37. 1 note iron is listed as a micronutrient) S, ca, fe, mg common in most soils, plants aren"t growing as well is because their missing one of these. How to remember the macronutrients (know this really well) Another group of nutrients is only needed in small amounts (<1% of the plant"s dry weight), these are the micronutrients.
