phosphorus

[@amckinney50]

There needs to be more lecture type videos like this about turf out there. Keep up the good work.

finally something good about phosphorus, thanks

Correction factor? I know what it means, but how is that applied on fertilizers excactly? Is it an estimate of soil type you're going to spread it on?

10 months late, it is the amount of Phosphorus in Phosphorus Oxide. Which means per 1lb of Phosphorus Oxide, there is 0.437 lbs of Phosphorus. Calculation is done by stoichiometry. Phosphorus Oxide is 142 lb/lbmol and Phosphorus is 31 lb/lbmol since there is 2 lbmol P in P2O5 you multiply that by 2. 142/62 = 0.437 This is important for researchers so they can calculate the appropriate amount of phosphorus needed for their fertilizers. Excess phosphorus can lead to oversaturation in the soil making it hard for other nutrient absorption, this can lead into stunting of plant growth. I'm sure there are more reasons (eutrophication like the one talked on this vid).

But it's been said in many vedios that iron, zinc uptake of plants will only happen in low pH. So if there is a high amount of phosphorus in soil all the iron and zinc will be consumed by reacting with phosphorus. So if we could maintain a high pH level phosphorus won't disturb the uptake of iron or zinc as per the explanation? Hoping for a response as I have some iron deficiency issue, which has a lot of different explanation on KZbin

Nyc make vedio on Potassium
