Document Summary
-- texture is the relative amounts of various sizes of soils particles. -- composition is relative amounts of inorganic and organic components. (whats this. 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. Nutrients are the things the plant directly needs to grow. Condition refers to how the soil is (the texture, moisture, hardness). The composition is what is the exact nutrients thing like metting the nutrient value of the plants) 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) The percentage of the microorganism is composed of the element in its dry weight is how micro and macro are distinguished.
