Correct Answers- Latest Test | Graded A+ |

Note the various forms of N


✓ -:- 1. Ammonium (NH4+) cation in the soil solution and fixed in secondary clays

2. Nitrate (NO3-) anion in the soil solution


3. Organic N in the soil


4. Ammonia (NH3) gas (released to atmosphere)


5. NO, N2O, N2 gases (released to atmosphere)




anion- nitrogen


✓ -:- it is not held by soil colloids and can be lost from the soil

through leaching. However in well aerated soils (plenty of oxygen), most of the NH4+-N


(applied for example as fertilizer) changes to the NO3--N form by a process called

nitrification




cation-nitrogen

✓ -:- it can be held on the exchange sites of soil colloids which makes it available for

plant uptake over a long period of

time.




Describe one reaction that leads to loss of N from the soil:


✓ -:- Nitrate leaching into ground

water.




symbiotic N2 fixation that occurs between legumes and rhizobium


species.


✓ -:- Host plant supplies the N fixing organisms with fixed C (photosynthate which is

used for respiration and N2 fixation), and the host plant benefits from the fixed N.




N2 fixation is a reduction reaction and happens in the nodule in a completely anaerobic

environment




inorganic P

✓ -:- found in insoluble compounds in the soil




N is found in two forms:


✓ -:- 1) Ammonium (NH4+) - cation

2) Nitrate (NO3-) - anion




NH4 and NO3 in soil solution constitute about 1% of N in the soil. Again most of the N in

soils is in organic forms.




Due to rapid nitrification in soils, plants absorb predominately NO3.




Some plants prefer N in the NH4 form for example rice. Other plans that grow under acidic

conditions seem to prefer NH4 too.




ATP


✓ -:- adenosine triphosphate (drives most energy-requiring biochemical processes ex

uptake of nutrient)
