The farms which work on high volume mostly use conventional methods with some alternative practices used such as green manure crops, cover crops and composted material... Their conventional production system uses holistic methods to ensure sustainable agriculture, including practices like compost at 4-5 tonnes per hectare per year spread over the fields, and six-year rotations as a minimum for vegetables... Many of the businesses using conventional methods realised the importance of soil health and the need to improve their soils to maintain current production...

This species of grass was most commonly used in an intensive grazing dairy system where it would run 40 head of cattle on 0.6 ha for three days with a rest period of 28-32 days (Moreira, 2012)... Recent reports would suggest that psyllid damage is sometimes reduced and stocking rates have in places returned to normal... As shown below FTAI has the ability to increase the percentage of cows in calf...

Trangie Grains Research Update Precision farming, controlled traffic & farming systems.. Grains Research Update - Trangie August 2002 of weathering of Australian soils, resulting in a lower soluble mineral concentration in the soil water... Other issues Given the above results from our demonstration sites and issues raised concerning direct seeding and controlled traffic in the context of conservation farming, we believe more work still needs to be conducted to enable us and the machinery / adviser industry to more adequately offer advice to farmers on machinery / farming systems options...

The objective of my study was to understand the principals behind carbon trade and the on ground farming practices that may enhance soil health, increase sequestration and potentially increase greater amounts of soil carbon... I firmly believe that agriculture has a positive role to play in carbon sequestration and although not the sole answer to reducing all CO 2 emissions farmers and farming operations deserve good information to serve them now and into the future... 1% OC = 3.6 kg/m 2= 14.4 litres/m 2= 144,000 litres/ ha The above calculation shows that an increase of 14.4 litres of extra plant available water could be stored per square metre in the top 30cm of soil with a bulk density of 1.2g/m 3, for every 1% increase in the level of soil organic carbon in addition to the current water holding capacity of the soil itself...

Recent Grains Research and Development Corporation-funded (GRDC) research in the northern region shows native remnant vegetation measures around three per cent soil organic carbon (OC) in the top 10 centimetres of the soil... Soil that has been cropped long term is about 1% OC, which indicates long term cropping has decreased OC by 2%.This is a massive drop in the real value of land... A 2% decrease equates to at least 20 tonnes per hectare of OC lost from the soil (assuming bulk density of only 1.0)...
