The total available metal pool, C, is defined as metals extractable by organic acids in the rhizosphere of growing plants and k is related to the kinetics of metal release by organic acids. Half-life of the available metals in biosolids-amended soils may be derived from k.Experiments were conducted to characterize the concentration and composition of the organic acids. A successive extraction method was used to extract metals from biosolids-treated soils for determinging C and k. In this manner, the plant available metals of the biosolids-treated soils are defined by the total available metals, half-life, and duration of plant growing.","brand":"Gardners","offers":[{"title":"Default Title","offer_id":57490292769141,"sku":"9781843396796","price":145.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/7193\/3106\/files\/9781843396796.jpg?v=1786442179","url":"https:\/\/backstory.london\/products\/assessing-bioavailability-of-metals-in-biosolids-treated-soils","provider":"Backstory","version":"1.0","type":"link"}
