南瓜子仁的功效与作用摘要：Iron pyrites are waste products from mining operations and are also mined products. They have been ud with varying success to supply Fe to plants, to supply S to plants, and to ameliorate sodic soils when oxidized to acid which forms gypsum in calcareous soil. Several forms of pyrite exist depending upon origin and crystallinity. Most of the literature indicates that oxidation of pyrite in soil is s
low and sometimes requires years depending on origin and particle size; the need for small particle size is critical. Often the only practical respon to the pyrite is from oxidation that has occurred before application. Soilsurface applied pyrite ems to give more respon than incorporated pyrite. Impure pyrite ems to give better results than near pure pyrite, and new rearch needs to focus on the reasons. Possible reasons
