Samples were collected in north-eastern France (Lorraine Region), from the ploughed horizon (0-20 cm) of 4 soils: a Luvisol (Luv), 2 calcaric Cambisols (Calc1 and Calc2), and a magnesic Cambisol on serpentine (Serp).
Only 30% of Ni was exchangeable within 90 days in Calc2. Also, the intensity ranged from 14 [micro]g Ni/L for Calc2 to 88 for Serp.
Ni concentration in 77 aestivum shoots was <1 [micro]g Ni/g DM on Luv, Calc1, and Calc2 (Table 4).

Calc2 version 1.2 is a Windows-based application that combines a full-featured calculator with a unique 26-column tape, the CalcSheet.
Calc2 toggles between a standard and scientific calculator, has a fully editable display, memory functions and parentheses to simplify the entry of complex calculations.
Using Calc2's calculator, it's easy to enter calculations.
The heart of Calc2 is the CalcSheet, which lets you work with 26 columns and 9,999 rows.
With its unlimited undo and redo capabilities, Calc2 lets you correct errors, from simple typos to accidental erasures of entire CalcSheets.
Calc2 features OLE2 linking and embedding capabilities, allowing calculations to be included in word processing files, presentation documents, or any OLE-capable files.
Calc2 is fully configurable, allowing users to change the font of any field and change the default font, show or hide the calculator or CalcSheet, control the size and format of all numbers, and determine where comments will appear.
