Influence of soil organic matter, fertiliser formulation and season on fertiliser nitrogen use efficiency in temperate pastures
Intensively grazed dairy systems use high inputs of fertiliser nitrogen (N), and often supplementary irrigation, to ensure adequate pasture...

Nitrogen isotope enrichment predicts growth response of Pinus radiata in New Zealand to nitrogen fertiliser addition
The fertiliser growth response of planted forests can vary due to differences in site-specific factors like climate and soil fertility. We identified...

Higher maize yields and lower ammonia emissions by replacing synthetic nitrogen fertiliser with manure in the North China plain
Ammonia (NH 3 ) emitted from synthetic nitrogen (N) fertiliser applications to farmland leads to air pollution and terrestrial acidification. Previous...

Interaction between soil and fertiliser nitrogen drives plant nitrogen uptake and nitrous oxide (N2O) emissions in tropical sugarcane systems
AimsHigh nitrogen (N) fertiliser inputs in intensive sugarcane systems drive productivity but also significant emissions of nitrous oxide (N 2 O), a...

Assessing fertiliser-induced adulteration and nutrient imbalance in paddy-growing soils in Punjab, India
The excessive and imbalanced use of fertilisers in agriculture has opposite effects on human health and the environment. Punjab has the highest...

The role of an Ascophyllum nodosum extract in lowering the environmental impact and improving nitrogen use efficiency in pasture systems under a reduced nitrogen regime
Nitrogen is a macronutrient that is applied in substantial amounts as a chemical fertiliser to conventional agricultural systems. However, loss of...

Potassium and magnesium uptake and fertiliser use efficiency by oil palm at contrasting sites in Sumatra, Indonesia
The accuracy of fertiliser recommendations can be improved by knowledge of use efficiency of applied nutrients. The aim of this work was to determine...

Can zeolites be used in sugarcane crop** systems to help reduce nitrogen losses into the Australian Great Barrier Reef?
AimsThe aim of this study was to determine the effectiveness of natural (NatZeo) and acid-treated (AcidZeo) zeolites in increasing the nitrogen (N)...

Current Phosphorus and Potassium Fertiliser Application Rates Do Not Limit Tuber Yield and Quality in Potato Production Systems in the Netherlands
Current ware potato yields in the Netherlands are approximately 70% of their potential. It is hypothesised by several stakeholders within the potato...

Phosphorus fertiliser value of sewage sludge ash applied to soils differing in phosphate buffering and phosphate sorption capacity
The global phosphate rock reserves that underpin phosphorus (P) fertiliser production are finite. Recovery of P from waste streams (e.g., by...

Mitigate N2O emissions while maintaining sugarcane yield using enhanced efficiency fertilisers and reduced nitrogen rates
Conventional fertiliser nitrogen (N) inputs to sugarcane farming promote gaseous losses of the greenhouse gas nitrous oxide (N 2 O). This study...

Stable isotope techniques for quantifying N fertiliser recovery in maize grown in soils with different management histories
The 15 N natural abundance (NA) method is increasingly used to quantify fertiliser N recovery by crops, even though this method does not always...

Improving nitrogen use efficiency in irrigated cotton production
Irrigated cotton in Australia is mainly grown on heavy textured soils which are prone to waterlogging, resulting in significant losses of nitrogen...
