“…Soil P, K, Ca and Mg were extracted by acid ammonium acetate (0.5 M acetic acid, 0.5 M ammonium acetate, pH 4.65, ratio 1:10 v/v, 1 h) (Vuorinen and Mäkitie 1955). Soil boron was extracted by hot water (Berger andTruog 1944) Vol. 11 (2002): 301-310. and copper and manganese by acid ammonium acetate-EDTA solution (Lakanen and Erviö 1971).…”

The nutritional status on commercial currant fields was elucidated by advisory analytical data of 357 pairs of soil and leaf samples from commercial black, red and white currant fields in Southern and Middle Finland. The purpose was to investigate how nutrient concentrations in soil and leaves fitted in the recommended ranges, correlated with each other and to evaluate their usefulness in diagnosis of nutritional status. Soil pH(H 2 O) and extractable nutrients (NO 3 -N, P, K, Ca, Mg, B, Cu, Mn) and leaf nutrients (N, P, K, Ca, Mg, B) were analysed. The mean soil pH, P, K and Mn were in the recommended ranges. Over 50% of soil P and 60% of Mg results and the greatest part of Ca results passed below the lower recommended limits, but soil B and Cu were frequently over the upper recommended limits. The mean leaf N, P and K on all currants, Mg on black and red currants and Ca and B on black currant were within the recommended limits. The lower recommended limit of Mg was passed below in 74% of white currant leaf samples. Positive correlations were found between soil and leaf nutrient concentrations for P, Ca and Mg. The recommended lower soil analysis limits might possibly be too high for coarse soils, because low values of soil P, Mg and Ca were common. The nutrients also might not be evenly distributed in the sampled soil layer but might be accumulated in a thin surface soil layer because of repeated surface broadcasting of fertilizers.

Boron (B) deficiency in crops is a major micronutrient disorder particularly in alkaline-calcareous soils. A nutrient indexing of rainfed sorghum [Sorghum bicolor (L.) Merr; cv. in the Potohar plateau of Pakistan revealed B deficiency in 50% of the 140 sampled fields in Jehlum district and 115 fields in Chakwal district. Hot water extractable (HWE) B in the associated soils, however, indicated more widespread B deficiency. The 255 sampled fields represented 21 soil series: 100 belonging to Alfisols, 63 to Entisols, 50 to Inceptisols, and 42 to Aridisols. Boron fertility varied in various soil types; the minimum HWE B (0.25 mg/kg) was noted in Calci Ustochrepts and the maximum (0.69 mg/kg) in Fleventic Ustochrepts. Boron fertilization of an alkaline calcareous Typic Ustorthents (HWE B, 0.11 mg/kg) increased grain yield up to 32% in improved sorghum (cv. PARC-SS-1) and 29% in local sorghum (cv. Potohar 4-8) over the respective control yields. Fertilizer requirements for near-maximum (95%) grain yield was 1.2 mg B/kg for the improved and 0.6 mg B/kg for local cultivar; higher fertilizer requirement of improved sorghum may be attributed to its greater biomass production. Critical plant tissue B concentration in improved sorghum was 17 mg/kg in whole shoots and 25 mg/kg in most recently matured leaves. Contrary to its 441 Copyright © 1997 by Marcel Dekker, Inc. Downloaded by [University of Connecticut] at 22:16 13 October 2014 442 RASHID, RAFIQUE, AND BUGHIOlesser fertilizer requirement, internal B requirement of local sorghum was greater, i.e., 18 mg/kg in whole shoots and 31 mg/kg in leaves. The three soil tests for B, hot water, hydrochloric acid (HC1), and mannitol were almost equally effective in evaluating soil B fertility. Soil test critical B levels (mg/ kg) for improved sorghum were: hot water, 0.48; HC1, 0.43; and mannitol, 0.37. Contrary to its internal B requirements, soil test critical B levels (mg/ kg) were slightly lower for local sorghum, i.e., hot water, 0.45; HC1, 0.40; and mannitol, 0.36. Thus, local sorghum appeared more efficient in utilizing soil B. As soil test critical levels as well as fertilizer requirement were greater for improved sorghum, a much widespread B deficiency is expected in this cultivar if grown on alkaline calcareous soils of the Potohar plateau.

“…The technique used to analyze boron in clay samples was essentially a combination of the fusion-solution method of Berger and Truog (1944) and the carmine colorimetric method of Hatcher and Wilcox (1950). Duplicate and triplicate analyses of selected samples indicate the results are reproducible within about __+ 5 per cent of total boron present for untreated samples and about + 10 per cent when the additional variables of treatment and washing are introduced.…”

Abstract-The mechanism of boron uptake by clays, especially illitic clays, and the factors which control such uptake have long been debated issues. In an attempt to answer some of the questions of the controversy, three illites were treated in solutions containing boron. In the study, boron concentration, salinity, temperature, and time were varied independently over rather wide ranges.For the illites studied, irreversible uptake of boron was increased by increasing boron concentration, salt concentration, temperature, and time of treatment. The amount of boron which was fixed also varied with the type of illite treated. The amount of fixation was controlled primarily by the specific surface area of the clay and also by the crystallinity, K content, and/or amount of mixed-layer material ("frayed-edge" development?), and apparently was independent of the original boron content of the clay.A two-step mechanism is proposed for boron fixation by illite, consisting of rapid chemical adsorption of the tetrahedral B(OH)+ anion at the "frayed-edge" of the illite flake followed by much slower diffusion of boron into the tetrahedral part of the structure.
