  • Nutrition

    the supply and absorption of chemical compounds needed for growth and metabolism

  • Nutrients

    chemical compounds required by an organism

  • Metabolic processes

    the mechanism by which nutrients are converted to cellular material or used for energetic purposes

  • Metabolism

    encompasses the various reactions occurring in a living cell in order to maintain life and growth

  • Anabolism

    build-up process

  • Catabolism

    breakdown process

  • Plant nutrition

    is a term that takes into account the interrelationships of mineral elements in the growth medium as well as their role in plant growth.

  • Soil fertility

    The capacity of a soil to provide crops with essential plant nutrients in right amount and available form

  • Soil productivity

    the capability of soil to produce specified crop yield under well defined and specified systems of management of inputs and environmental conditions.

  • loose surface of the earth as distinguished from solid bedrock

    geologic definition

  • material which nourishes and support plant growth

    traditional definition

  • mixture of mineral matter, organic matter, water, and air

    component definition

  • living, dynamic system which forms at the interface between the atmosphere and lithosphere in response to forces exerted by climate and living organisms acting on parent material as conditioned by topography/relief over a period of time

    soil definition

  • Mica, Amphiboles, Quartz, Feldspar, Carbonate minerals

    primary minerals

  • Humin

    causes the blackness of the soil from humus

  • Fulvic acid, Humic acid, Humin

    components of humus

  • Clay minerals, Soil solution, OM surfaces

    site for chemical reaction in soil

  • higher specific surface area

    why do clay minerals have more CEC

  • Adsorption reactions

    more important in controlling plant nutrient element availability than the release of nutrient element by mineral weathering

  • orthoclase, sanidine, microcline

    feldspar

  • Muscovite, biotite, phlogopite

    Micas

  • SiO4

    quartz chemical comp

  • Soil minerals

    are the products of the weathering of underlying rock in place, or the weathering of transported sediments or rock fragments.

  • Humus

    When the organic matter is fully broken down, one of the things that is left is

  • carboxyl (-COOH), hydroxyl (-OH) and amide(-NH).

    in humus CEC occurs in reactive groups such as

  • and also carbon dioxide

    soil air contains a far great amount of water vapor than atmospheric air

  • SO4 2-

    sulfur ion that can be absorbed

  • NH4+, NO3-

    nitrogen ion that can be absorbe

  • H2PO4-, HPO42-

    phosphorus that can be absorbed
