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.\u003cbr\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Rarewaves","offers":[{"title":"Default Title","offer_id":57874301714806,"sku":"9781843396796","price":168.89,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/www.rarewaves.com\/products\/9781843396796-assessing-bioavailability-of-metals-in-biosolids-treated-soils","provider":"Rarewaves.com","version":"1.0","type":"link"}
