Certified Crop Advisor Exam With 100%
Correct Answers 2024.
Macronutrients
nitrogen, phosphorus, potassium, calcium, magnesium, sulfur
Micronutrients
boron, chlorine, copper, iron, manganese, molybdenum, nickel, zinc
function of nitrogen
used in the synthesis of amino acids, protein's, enzymes; found in chlorophyll (photosynthesis), ADP and
ATP transfer
function of phosphorus
important component of energy transfer system, ADP and ATP, important to photosynthesis and
respiration, important to cell division
function of potassium
accelerates growth of meristematic tissue; regulation of water loss, involved in nitrogen and
carbohydrate metabolism, catalyzes some enzymes
function of sulfur
component of some amino acids, which are part of many proteins; involved in proteins synthesis and
enzyme activation; forms flavor compounds in mustard, garlic, and onions
how nutrient demands change as plant grows
increases in vegetative stage
rapidly increases in reproductive stage
decreases at harvest
role of soil solution
the water in the soil that contains dissolved ions, molecules, and gases that are nutrients absorbed by
the plant through mass flow, diffusion, and mass flow
role of cation exchange sites
these cations move to the soil solution by cation exchange and are readily available to plants
role of organic matter
soil organic matter can retain nutrients by cation exchange and can be a source of (N,P,S) when
decomposed
