Key points Malignant mesothelioma is a tumour of the mesothelial cells which occurs in the pleura in up to 90% of all cases, but can also occur in the peritoneum, pericardium, and testes. The term ‘mesothelioma’ is usually accepted as being synon

Losses of nitrogen from the soil and plant system have never been measured directly, and gains have almost always been estimated from conventional nitrogen balance experiments. A gas-tight assembly is described which is low cost and has been successf

In a series of experiments, 15N-labelled nitrate fertilizer was used to study the nitrogen balance of a heavy clay soil. Two of the experiments employed 60-cm deep, 16-cm diameter columns of packed soil. In the first, no added 15N was lost until heav

The stable isotope 15N was used to study the fate of nitrogen fertilizers applied to a black earth growing wheat. In a glasshouse experiment using soil packed at 56 % moisture (pF 2) into pots, added nitrate was almost completely recovered (mean, 98.

Recovery of 15N from labelled fertilizers was measured in open microplots on pastures at three sites in southern Queensland. Very little 15N was recovered from plants growing further than 15-30 cm from the area of application. Most of the 'N found in

Results are reported of the first of a series of studies on the fate of nitrogen applied to soil under pasture. Two series of pretreatments (nil and 200 lb/ac N) were imposed on Rhodes grass, Chloris gayana Kunth, grown on a light-textured soil in po

A study of the equilibrium levels of moisture, nitrate nitrogen, and ammonium nitrogen is reported on two representative black soils (developed from basaltic colluvium and alluvium respectively) from the Darling Downs for the years 1952-1954 inclusiv

There was a marked accumulation of soil nitrogen and carbon at the soil surface after five or six years' growth of a fertilized Desmodium uncinatum pasture on a lateritic podzolic soil at Beerwah, in south-eastern Queensland. With adequate superphosp

Setaria (Setaria sphacelata cv. Nandi) was grown in 10 surface soils, of contrasting properties, in pots until (after repeated harvesting of tops) plant growth virtually ceased. Uptake of potassium by tops and roots was correlated with change in exch

Rates of nitrification of a black clay soil were studied with the percolation technique, using samples from various depths down to 3 ft. There was a marked decrease in nitrification rate with increasing depth, the successive curves showing longer lag
