“…In our experiment the threshold Ni concentration (causing mild chlorosis) in oat shoots was 79 mg/kg. Oat response in our study was comparable to that reported by Anderson et al (1973) who observed severe toxicity of oats containing 117 mg kg −1 and moderate toxicity of plants containing 88 mg Ni kg −1 of dry matter while Crooke (Roth et al 1971;MacNicol and Beckett 1985;Sauerbeck and Hein 1991;Chang et al 1992;Guo et al 1995;Kukier and Chaney 2004) reveal a variation of Ni-phytotoxicity thresholds in different plant species and cultivars, indicating that plant species should be taken into consideration when interpreting Ni phytotoxicity and the need for soil Ni remediation. The need for Mn fertilization of limed organic soils in Port Colborne area has become evident from previous studies (Kukier and Chaney 2000) while Mn fertilizer was not needed for remediation of a mineral soil from the region (Kukier and Chaney 2001;Siebielec and Chaney 2006).…”

Historic emissions from a Ni refinery at Port Colborne, Ontario, caused Ni contamination of regional soils and raised concerns about potential Ni phytotoxicity. Previous tests revealed that if these soils were made alkaline and fertilized with Mn and other common nutrients as needed to maintain fertility of such alkaline soils, full remediation (prevention of Ni phytotoxicity) would be obtained. This experiment was conducted to test this method of remediation on diverse soils from Port Colborne, and to evaluate chemical extraction tests which would be predictive of plant uptake and potential for Ni phytotoxicity in Ni-contaminated soils. Ten soils with varied levels of Ni contamination and varied soil properties were amended with limestone or nitric acid to raise or lower pH so that a wide pH range could be examined for the soils. For lower Ni organic and mineral soils near the Ontario remediation limit (200 mg/kg), neither crop suffered Ni phytotoxicity at any pH tested. Only when more highly contaminated soils were strongly acidic did Ni phytotoxicity occur. Phytotoxic soils were fully remediated by making soils alkaline even for these Ni-sensitive crop species. Only the most contaminated organic soil remained slightly toxic -but this soil was remarkably contaminated (over 1.1% of Ni). The Sr nitrate extraction method was much more effective in predicting plant Ni concentrations than the DTPA method. This test provides an inexpensive soil extraction result highly predictive of potential for Ni phytotoxicity across soils.

“…Leaves showing Ni-induced chlorosis are found to contain sub-optimal levels of Fe (NICHOLAS et al 1957;ROTH et al 1971); in some cases Ni-induced chlorosis may be alleviated by foliar applications of FeS0 4 (HEWITT 1948(HEWITT , 1953, suggesting an effect of Ni on the translocation of Fe (LINGLE et al 1963;WALLACE and DE KOCK 1966).…”

“…Furthermore, Chaney et al (27) reported that as much as 700 mg kg" 1 of Zn 2+ in soybean trifoliates were nontoxic. Potential toxicities from excess Cu 2+ and Ni 2+ were also discounted because plant contents were far below the 220 and 50 mg kg' respectively, suggested by Roth et al (28) as being the critical, toxic concentrations.…”

Extracting sludge-amended soil with DTPA does not always give a reliable measure of plant-available heavy metals. The major purpose of this greenhouse pot study was to help explain why. Two anaerobically digested sludges from sewages treated with either Ca(OH) 2 or FeCl 3 were applied to 3-kg samples of a Mollic Albaqualf previously limed with Ca(OH) 2 rates of 0, 2.5, and l0g/pot that resulted in pHs in the check pots of 5.4, 6.2, or 7.7 after the first harvest. Sludge rates provided 0, 200, 40, 800, and 1600 mg Zn kg -1 of soil. Two consecutive crops of soybeans (Glycine Max L.) were grown for 42 d each in the greenhouse. DTPA-extractable, soil-solution, and plant concentrations of Cu 2+ , Ni 2+ , and Zn 2+ were measured.
