Document Summary
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. weathering of rock components (life forms) -- composition: encompasses the inorganic (mineral) material and organic chemical. -- texture: depends on the sizes of soil particles, which arise ultimately from the. Inorganic: the surface charges of soil particles determine their ability to bind many nutrients. C, h, o, p, k, n, s, ca, fe, mg. 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) Another group of nutrients is only needed in small amounts (<1% of the plant"s dry weight), these are the micronutrients.
