This is a horrible article. Phosphorus is needed in relatively small quantities during flowering, unless you're growing seeds. Calcium is needed in higher quantities, and it is considered a micronutrient. Furthermore phosphorus is a major pollutant in freshwater lakes and streams, and should be used sparingly. ALL forms of manure potentially contain pathogens and parasites and should be composted before growing anything in it. Phosphorus cannot be broken down by enzyme-catalyzed chemical processes and thus have little effect on flushing excess P from a soil solution. Finally it omits any discussion about mycorrhizae uptake of phosphorus in soils. Was this written by AI? 3/10 from me.
