Viljavuustutkimuksen määrityksen virhe (variatiokerroin) on rutiinianalyyseissä, aivan ravinneköyhiä maita lukuunottamatta keskimäärin; pH ±2.2 %, Ca ±5.9 %. K ±7.2 % ja P ±9.7 %. Analyysissä aiheutuvat suurimmat virheet määrityskojeide

The correlation between CEC-values obtained by ammonium acetate and methylene-blue adsorption methods is relatively good (r = 0.86***). The latter method gives, however, about 30 per cent lower values for exchangeable cations. The extraction ratio us

The extractant, 0.5 M acetic acid –0.5 M ammonium acetate at pH 4.65, which is used in soil-testing, extracts relatively high amounts of aluminium from acid soils. The mean values of acetate-extractable aluminium at pH 4.65, 1.75 meq Al/100 g of so

The experiments show that under these conditions the common trace nutrients, cobalt, copper, manganese, molybdenum and zinc are sufficiently completely extracted as chelates by shaking the soil extract with oxine-chloroform solution. The hydrogen ion

The formation of chelates between aluminium(III) and 3-hydroxy-7-sulpho-2-naphthoic acid has been studied in aqueous solutions of various ionic strengths, at 298 K. The stability constants of AlL, AlL 2 and AlL 3 and the protonation constants of the

Simple direct dilution methods are described for the analysis of urinary chromium and nickel with electrothermal atomic absorption spectrometry. The day-to-day variation of the methods is in the order of 5%, and the detection limits 20 and 0.1 nmol/l
