Urease Activity, Ammonia Volatilisation and Related Microbiological Aspects in Some South African Soils
Urease activity of various soils was indexed employing toluene sterile and non-sterile soils. The two methods indicated that part played by microorganisms. Apparatus used, soil depth, increment, depth of placement and pattern distributions are discussed in relation to volatile loss as are influences of soil moisture, reaction, temperature and drying-out. Urea on trash benefits fungi but invaria...

متن کاملEnhanced-efficiency fertilizers in nitrous oxide emissions from urea applied to sugarcane.
The environmental benefits of producing biofuels from sugarcane have been questioned due to greenhouse gas emissions during the biomass production stage, especially nitrous oxide (NO) associated with nitrogen (N) fertilization. The objective of this work was to evaluate the use of nitrification inhibitors (NIs) dicyandiamide (DCD) and 3,4 dimethylpyrazole phosphate (DMPP) and a controlled-relea...
متن کاملEffect of Anhydrous Ammonia on Cane Yield, Nematodes and Eldana
Anhydrous ammonia has higher concentrations of nitrogen (82% N) than urea (46% N), is usually more economical, has lower labour requirements for application and is less prone to volatilisation. It has also been shown that ammonia has nematicidal properties. It would be of great benefit to the sugar industry if anhydrous ammonia could be applied as both a fertiliser and as a nematicide for the s...
