Understanding plant uptake of organic and inorganic nitrogen for optimal fertiliser application in forestry. Nitrogen (N) in soils occurs in both organic and inorganic forms. Plants can take up inorganic N - nitrate and ammonium - but, on average, these account for only 5% of the soluble N in soils. Recent evidence suggests that plants may be able to tap into some of the 95% of N that occurs in organic forms. We will investigate the importance of organic N uptake for two plantation Eucalyptus sp ....Understanding plant uptake of organic and inorganic nitrogen for optimal fertiliser application in forestry. Nitrogen (N) in soils occurs in both organic and inorganic forms. Plants can take up inorganic N - nitrate and ammonium - but, on average, these account for only 5% of the soluble N in soils. Recent evidence suggests that plants may be able to tap into some of the 95% of N that occurs in organic forms. We will investigate the importance of organic N uptake for two plantation Eucalyptus species by tracing the uptake of different N forms by bacteria, fungi and eucalypts. This information will redefine what is meant by 'available N' and will guide the development of a new test for soil N status.Read moreRead less
Managing urban trees. Managing urban trees. This project aims to explore the effects of different urban tree types and plantings on people and wildlife in Melbourne, Moreland and Ballarat so they can better plan their future urban forests. Local governments spend millions of dollars planting and maintaining urban trees every year. Research provides little guidance to these land managers when making critical decisions in a rapidly changing social and physical environment. This project will combin ....Managing urban trees. Managing urban trees. This project aims to explore the effects of different urban tree types and plantings on people and wildlife in Melbourne, Moreland and Ballarat so they can better plan their future urban forests. Local governments spend millions of dollars planting and maintaining urban trees every year. Research provides little guidance to these land managers when making critical decisions in a rapidly changing social and physical environment. This project will combine tree inventory data with new information on the social and ecological effects of trees (e.g. human well-being, bird diversity). This research is expected to guide future tree management decisions that have better social and environmental outcomes for Australia’s cities.Read moreRead less
