Abstract: We examined the absorption of Zn, Cr and Mn into Brassica campestris L. cultivated in Brown Lowland soil (BL soil), Andosol and Brown Forest soil (BF soil) after five years' applications of chemical fertilizer (CHF), cattle farmyard manure (CFM) and pig farmyard manure (PFM). The effects of animal manure applications on the absorption of Zn, Cr and Mn by B. campestris were estimated by comparing the result in the CFM- and PFM-applied plots with that in CHF-applied plot. Zinc, Cr and Mn in B. campestris were measured by the instrumental neutron activation analysis (INAA) to perform total simultaneous analysis at a high sensitivity. The results obtained in this study were summarized as follows: 1) For Zn and Cr in B. campestris, the results obtained from INAA were compared with a nitric acid-digestion method (NADM). Results obtained from the INAA and NADM were fully in agreement for Zn, but not in agreement for Cr. The Cr concentration in B. campestris determined using NADM was only 13-2727777671520f that determined by INAA. From the results above, it is suggested that INAA could be used to analyze the correct amounts of trace elements removed by B. campestris. 2) CFM application increased Cr concentration in B. campestris cultivated in BL soil and Zn concentration cultivated in BF soil, while decreased Cr and Mn concentrations cultivated in Andsol and Cr and Mn cultivated in BF soil. PFM application led to a significant increase on the Zn concentration in B. campestris cultivated in BL soil, Zn and Mn cultivated in Andsol and Zn, Cr and Mn cultivated in BF soil. In BL soil, PFM application tended to decrease the Cr concentration in B. campestris. For Zn, Cr and Mn in CFM-applied plot of BF soil, Cr and Mn in CFM-applied plot of Andsol and Cr in CFM- and PFM-applied plots of BL soil, the change of availability by B. campestris of Zn, Cr and Mn in animal manure may provide an important influence on the uptakes of these elements by B. campestris.
