Rough translation: p-index of how much phosphorous is present in soil, minus is loss of phosphate, plus is growth in phosphate
Phosphate is one of the primary minerals that make farms effective
Does it say in what time range the growth/loss is measured? Is it from 2000 to 2018 or something?
it seems to be per year, though my spanish literacy is no bueno.
