I have a greenhouse experiment in which I need to grow my seedlings in a phosphorus-free soil. How can I remove P through using acid washing. I will use large quantities of sandy soil ?
Thank you in advance
Go for fully washed and drained sand culture and apply soluble fertilizers excluding P.
Thank Mr. Singh for your answer, but the question for me is how? If you have a methodology to do it, could you please share it with me?
You can wash the sand in a concrete mixer until the water is clean. You can also, if you have enough, soak the sand in an acid solution using a concrete mixer.
Phosphorus can not be removed scientifically because soil origin is minerals and phosphorus is part of minerals
The idea here is to remove the available P. I found that it can be eliminated via acid washing, but I did not find how can I do it for +/- quite amount of soil which I will use for my greenhouse experiment?
