{"product_id":"controlled-release-of-soil-active-herbicides-von-craig-ramsey","title":"Controlled Release of Soil Active Herbicides","description":"\u003cp\u003eSoil activated herbicides such as hexazinone have  chemical properties that increase their potential  for leaching out of the root zone in regions with  sandy soil and high rainfall patterns.  Activated  charcoal may form reversible physical bonds with  such herbicides, depending on their chemical  properties.  The powdered form of charcoal can be  preabsorbed with a suitable herbicide and then  applied for weed control uses as directed by the  herbicide label.  Physical absorption onto the  charcoal protects the active ingredients from biotic  and abiotic degradation until rainfall releases the  herbicide from the charcoal surfaces.  Each rainfall  event releases a percentage of the active  ingredients so that effective weed control can be  maintained over a longer time period. The critical  factors for making this an effective weed control  formulation are the charcoal and herbicide  properties, the mixing ratio, soil properties and  the rainfall patterns.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838360829\"\u003e\u003ch3\u003eUse of Activated Charcoal for Extended Weed Control\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838360829","offer_id":39499042259037,"sku":"9783838360829","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/25e288a6-fbc0-4188-93aa-89cbc50a04db.jpg?v=1737183072","url":"https:\/\/shop.autorenwelt.de\/products\/controlled-release-of-soil-active-herbicides-von-craig-ramsey","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
