Excessive nitrogen fertiliser use reduces efficiency and causes significant damage to the environment. Carbon fertilisers have advantage of improving soil fertility; however, effects carbon on rice yield quality are not clear. In this study, nitrogen-efficient line (OsNRT2.3b-overexpressing [O8]) wild type (WT) were treated with different levels under field conditions study fertilisation treatm...

The impact of long-term grassland management regimes on microbial community structure in soils was assessed using multivariate analysis of polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) banding patterns of selected bacterial groups and PLFA (phospholipid fatty acid) profiling. The management regimes assessed were inorganic nitrogen (N) fertiliser application and so...

Human urine obtained from separating toilets was tested as a fertiliser for cultivation of outdoor cucumber (Cucumis sativus L.) in a Nordic climate. The urine used contained high amounts of nitrogen with some phosphorus and potassium, but numbers of enteric microorganisms were low even though urine had not been preserved before sampling. The cucumber yield after urine fertilisation was similar...

This paper reports the results of a 2-year study of water quality in the River Enborne, a rural river in lowland England. Concentrations of nitrogen and phosphorus species and other chemical determinands were monitored both at high-frequency (hourly), using automated in situ instrumentation, and by manual weekly sampling and laboratory analysis. The catchment land use is largely agricultural, w...

Intensive vegetable production in southern Australia is characterised by high inputs of nitrogen (N) fertiliser, water, and occasionally animal manures, which creates the potential for high nitrous oxide (N2O) emissions. Three field experiments were conducted to investigate the effects of the nitrification inhibitors 3, 4-dimethylpyrazole phosphate (DMPP), 3-methyl pyrazole plus 1H-1,2,4 triazo...

The fertility status of the soil and the standard of fertiliser management can have an important effect on the chemical composition and quality of cane juice. Both nutrient deficiency and nutrient excess can result in below optimum sucrose contents. Excessive potassium uptake may promote cane lodging and high potassium levels in juice can also influence the exhaustibility of final molasses, the...
