| Abstract: | The constant temperiture experiment and pot experiment have been conducted for studying effects of organic manure on Zn,Mn in soils.The main results are summaried as follows: 1 Pig manure,cow manure and corn straw are good fertilizers for providing plants with Zn and Mn nutrients. 2 The application of organic manure can increase the availabilities of Zn and Mn in soils.The increase of DTPA Zn,Mn maily lie in two aspects:one is O.M.(organic manure) with DTPA-Zn,Mn,another is activation of O.M.on original non avilable Zn and Mn when incubation of O.M.with soils.Organic acids can eomplex or disolve Zn,change of soil redox can increase DTPA -Mn of soils 3 O.M.can increase the amount of absorbed Zn,Mn in plants and reduce the fixation of zinc fertilizer in soils. |
