  1. Plant and Soil by Prof. Gernot K. Brueck, Ph.D. G4 General Trading LLC

  2. Plants consists of: • carbohydrats • sugars and/or • starch • proteins • aminoacids as basic element • peptides to polypeptides = proteins • water G4 General Trading LLC

  3. The only responsible miracle for all organic matter and any life in the world is: • Photosynthesis 6H2O (water) + 6CO2 (carbondioxid+ energie (light) = C6H12O6 (glycose) + 6 O2 (oxygen) beside it:bacteria, yeasts, molds as aminoacid producers G4 General Trading LLC

  4. The carbon cycle G4 General Trading LLC

  5. Which further elements are necessary ? • Nitrogen (N) • essential part of all aminoacids = proteins • Potassium (K) • responsible forprotein synthesis,control of ionic balance, regulation of plant stomata and water use, activation of plant enzymes and many other processes • Phosphorus (P) • essential part of the photosythesis and smaller amounts of Sulfur, Magnesium and Calcium which are left out in the further consideration, because their cycles are near to potassium G4 General Trading LLC

  6. The phosphorus cycle G4 General Trading LLC

  7. The potassium cycle G4 General Trading LLC

  8. The nitrogen cycle Aerobic processes (= high oxygen content) are converting any nitrogen compound into plant available nutrient and anaerobic processes are leading to nitrogen losses G4 General Trading LLC

  9. Summary • plant growth relevant • sufficient basic nutrients N-P-K in the soil • high oxygen content in the soil for just aerobic processes • avoiding anaerobic situations with N and root losses • sufficient water • if the organic matter remains at the place = in the cycle, no further fertilizers are necessary !
