Plants are autotrophs-
photosynthesis - for glucose autotroph: produces complex organic compounds (such as carbohydrates, fats, and proteins) from simple inorganic molecules using energy from light (by photosynthesis |
Non-Mineral Nutrients:
hydrogen (H), oxygen (O), & carbon (C). |
primary nutrients:
nitrogen (N), phosphorus (P), and potassium (K) Secondary nutrients: calcium (Ca), magnesium (Mg), and sulfur (S) |
|
|
Non-mineral nutrients, primary mineral nutrients and secondary mineral nutrients are essential for normal growth and thriving of plant.
|
Primary mineral nutrients get used up first and in great quantities so they are usually lacking from soil.
|
Nitrogen comes from Nitrogen-fixing, not weathered rock from bacteria. Such as rhizobium working with enzymes such as nitrogenase.
|
|
|
Micronutrients -essential for plant growth which are needed in only very small (micro) quantities .
These elements are sometimes called minor elements or trace elements |
The micronutrients are
boron (B), copper (Cu), iron (Fe), chloride (Cl), manganese (Mn), molybdenum (Mo) and zinc (Zn). |

Soil has 3 components:
Mineral (inorganic) matter Organic matter Pore spaces – containing air and wa |
-Mineral (inorganic) matter
-Organic matter --living --humus - partially decayed - Pore spaces – containing air and water |
soil organisms - organic matter decomposition, Decomposition of Organic Micronutrients, earthworms, etc, increases aeration and infiltration of water
soil atmosphere - pH of the soil soil water - mass of water divided by mass of dry soil, a measure of the amount of water in the soil |
