The good thing about the net is that everyone's an expert. Even those who believe they are well informed.

Which proves what exactly?
I think you may misunderstand what the net provides. When someone makes a statement which is not explained in any fashion, readers can quickly ask for more information. If the person who originally made the statement is unable to provide an explanation but resorts to attacking the questioner, then we are able to easily dismiss the original statement as worthless. The net provides a quick and easy way to expose "blowhards".duane wrote:

Paddock trees help soil fertility
As well as offering shade and shelter for livestock scattered paddock trees are good for soil health and pasture growth. Phoebe Barnes at the University of New England has been studying how paddock trees affect soil fertility both under the canopy and at distance from the tree. She found that paddock trees improved a range of soil nutrients both under and away from the tree.
In the paddocks the nutrients phosphorus, nitrogen and sulphur, as well as soil carbon were highest under the tree, and decreased moving away from the tree trunk. The higher nutrient levels were in the surface soil, suggesting a top down effect from leaf litter and possibly increased concentrations of animal manures. Soil moisture showed minimal additional extraction of water by the trees in the 0 – 30 cm zone suggesting little competition with pasture species.
The main message is that the effect from a single tree extends beyond its immediate canopy area, extending up to 16 m from the tree trunk for a mature tree. The results from this study suggest that a tree density of up to 11 large (with a canopy diameter of 13.5 m) well spaced trees per hectare could benefit soils and pasture growth by increasing surface soil pH by 0.5 units, soil carbon by up to 80%, available phosphorus by 70% and nitrogen by 20 % compared to a cleared paddock.
If you follow this link you will have some indication as to the priority weed control is given following the bushfires.Shirley Henderson wrote:. I heard there was a lot of weed control going on but do not agree that is a solution. At least they hold water, assist the small water cycle, provide habit, shelter, food sources, moderate temperature and provide groundcover etc etc etc........ Anyone know?
