THE EFFECT OF FIRE ON SOIL PROPERTIES

Fire significantly affects soil properties because organic matter (OM) located on,or near,the soil surface is rapidly combusted.The changes in OM,in turn,affect several chemical,physical,and microbiological properties of the underlying soil.Although some nutrients are volatilized and lost,most nutrients are made more available.Some results are removed in response to a notice of local law requirement.For more information,please see here.Previous123456NextSome results are removed in response to a notice of local law requirement.For more information,please see here.12345NextPhysical,chemical and antioxidant properties ofPhysical,chemical and antioxidant properties of pigmented rice grown in Southern Thailand Abstract Eight varieties of pigmented rice grown in southern Thailand,as a dehusked grain,were studied for their chemical compositions,antioxidant properties and color parameters.Moisture,protein,lipid,crude fiber
