Phosphate sorption isotherms and parameter values were determined on eight calcareous soils which were carefully decalcified using a procedure which minimized changes in cation saturation. Calcite content of the original soils varied from 0.8 to 24 2

SUMMARYDuring 1899–1964 various levels of 0·5 M sodium bicarbonate-soluble P had been established in an experiment on a sandy clay loam (pH 6·5–7·0) at Saxmundham, Suffolk. Modification made between 1965 and 1968 widened the range of soluble P

The Langmuir two-surface adsorption equation is used to derive a phosphate adsorption characteristic, the maximum buffer capacity, which integrates the intensive and extensive components of adsorption and is independent of P saturation. Changes in th

The effects of phosphate buffer capacity on the plant-availability of labile soil phosphate, when measured as intensity (I) or quantity (Q), are described and tested using results from a greenhouse experiment on 24 Sherborne soils. In multiple regres

A simple, sensitive method developed for the analysis of geostandards was used to measure the accumulation of Cd in soils from superphosphate applied annually to grass‐land and arable soils for many years. Rates of application were equivalent to 33

Summary For forty-one soils (pH > 5·0) from southern England and eastern Australia, the Langmuir equation was an excellent model for describing P adsorption from solutions < 103 M P, if it was assumed that adsorption occurs on two types of surface o

Summary The two-surface Langmuir equation was used to study P adsorption by 24 calcareous soils (pH 7.2-7.6; 0.8-24.2 per cent CaCO3) from the Sherborne soil series, which are derived from Jurassic limestone. High-energy P adsorption capacities (x″

In a heathland nursery on an acid sandy podsol and in a nursery on moderately acid agricultural land, four PK fertilizers were compared with superphosphate alone, using seedlings and transplants of Sitka sprucePicea sitchensis and Norway sprucePicea
