Soluble reactive p: mainly inorganic phosphate ( po4. Soluble unreactive p: consists mainly of organic p and. Lecture 12: relevant slides 6,9,13 , bottom part of 14. 6- soluble p: includes forms(organic/inorgo) that pass through a filter with pore size of 0. 45 micrometers directly taken up by plants polyphosphate ( chains of inorganic p) Particle p- includes organic and inorganic particles and colloids that micrometer filter. 13- fertilizer> deforestation + soil loss > sewage main p causes. 14-largest pool of p is in soil ~ how to make use of this as a plant: symbiotic relationship between roots and fungi~ fungi secrete phosphatase and plants supply organic carbon (energy) to fungi. 2. prolific root growth( plants without symbioses): increases p uptake rate (by surface area contact with soil) do not pass thorugh a 0. 45.
