P as fresh organic in flat residue newly decayed from organic matter blobs today: The amount of fresh organic P in the flat residue added to the mulch on top of this soil patch today from pulled or harvested plants and from decay of standing dead plant residue. Mulch fresh organic P moves into fresh organic P in the top soil layer.

P fertilizer added this year: The amount of P fertilizer automatically applied so far this calendar year to this soil patch. Auto fertilization applies only pure labile P to the soil (which is unrealistic).
