{"Page URL":"https://www.appropedia.org/Sulphur","Page description":"Elemental sulphur must be oxidized by soil microbes to SO4-S before it is available to crops. Thus, it takes considerably more time for S° to become available compared to soluble sulphate forms of fertilizer. The rate of conversion from Sø to plant available SO4-S mainly depends on the particle size to which the product degrades and the method of application. Research has determined that S° granules that break down into particles smaller than 150 Microns (10-6 m) convert quickly, since particles of this size (and smaller) provide sufficient surface area for microbes to act on. After two simulated wet/freeze cycles and one rainfall, SulFer 95 (0-0-0-95) are all <74 microns whereas only 25 per cent of Tiger 90 particles were <150 microns.","Page image":"File:Sulphur S (13403370265).jpg","Page language":"en","Page license":"CC-BY-SA-3.0","Page title":"Sulphur","Page views":"96","Page year":"Sunday, 01-Jan-06 00:00:00 UTC","Modification date":"Thursday, 27-Nov-25 22:55:36 UTC"}
