The measurement and distribution of urease activity in a pasture system
- E. Hoult, J. Mcgarity
- ChemistryPlant and Soil
- 1 October 1986
SummaryUrease activities of soil, litter and plant components of a pasture sward were measured by two methods. The type, height and age of the pasture sward can influence urease activity of the…

It was found that chickpeas were less sensitive to the inhibitory effects of NO3− than soybeans, and there appeared to be a trend suggesting an inhibitory effect of 6 mMNO3− on C2H2 reduction compared to 1.5 and 3.0 mM NO3 −.
THE PLANT COMPONENT AS A FACTOR IN AMMONIA VOLATILIZATION FROM PASTURE SWARDS
- J. Mcgarity, E. Hoult
- Chemistry
- 1 March 1971
The volatilization of ammonia which followed the application of urea to a pasture sod was determined over a period of 14 days. Significant ammonia losses were measured after foliar application of…

- ChemistryFertilizer Research
- 1 July 1988
Ammonia volatilization losses and other N transformations were studied in drill sown rice bays fertilized with urea at various times between permanent flooding (PF) and panicle initiation (PI).…

The influence of sward mass, defoliation and watering on ammonia volatilization losses from an Italian ryegrass sward topdressed with urea
- E. Hoult, J. Mcgarity
- ChemistryFertilizer Research
- 1 October 1987
Using intact pasture sods with 0.15m2 surface area and sealed in volatilization chambers, the influence of the mass of herbage on the ammonia volatilization losses following a surface application of…
Air temperature control in nitrogen volatilization chambers
- E. Hoult, E. Barlow, J. Mcgarity
- Environmental SciencePlant and Soil
- 1 April 1974
SummaryA volatilization chamber modified to produce within chamber air temperatures similar to ambient temperatures outside the chamber, and suitable for pasture studies in the field or glasshouse,…
Crop growth and nitrogen transformations in wheat (Triticum aestivum L.) planted after wetland rice (Oryza sativa L.)
- P. Bacon, E. Hoult, J. Mcgarity, D. Alter
- BiologyBiology and Fertility of Soils
- 1 September 1989
It is demonstrated that no-till systems increase crop yield and use of both fertilizer and soil N in intensive rice-based rotations and denitrification was maintained by continued release of metabolizable carbohydrate from the decaying rice stubble.
Urease activity on the phylloplane ― measurement and activity levels following urea application
- E. Hoult, J. Mcgarity
- Biology
- 1 August 1989
Using the proposed modifications of the urea hydrolysis method, urease activities on the phylloplane which had received urea dressings previously were shown to be depressed over the following 2 or 3 days due to the presence of ammonium ions.
