Abstract The Pi test is a new soil test for phosphorus P which uses a strip of iron oxide‐impregnated paper as a sink to adsorb P mobilized in a soil‐solution suspension The paper strips are prepared by immersing hardened filter paper circles in a 10 solution of ferric chloride then they are dried and exposed to ammonia vapor The paper is then cut into strips 10 cm long and 2 cm wide
As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
