Agriculture is often pointed at as the source of high greenhouse gas emissions. How can dairy farmers reduce their carbon footprint?
Farmers do not gain economic advantages because they make use of the Trace & Save tools. Farmers improve because they manage their farms better – the tools help them to do this.
The take-away challenge is for farmers to assess whether their fertiliser costs are decreasing per pasture produced. Are you growing cheaper pastures?
I hope this case study encourages farmers who are in the process of adapting their management in order to achieve greater nitrogen fertiliser efficiency.
The average water use across farms is therefore 911 litres of water per litre of milk. The main point I would like to make though is that the water use efficiency varies between the different farm systems.
The SWAN system is composed of soil, water, atmosphere and nutrient components. The best way to show how these integrated and interrelated measures reflect the journey of improving agricultural sustainability is to show a case study of a farm which has become more sustainable over the past five years.
This article will demonstrate that milk flocculation is caused by calcium instability which is induced by excess potassium on pasture systems. Also contributing is rumen pH fluctuations caused by rumen acidity or alkalinity due to sudden nutritional changes.
A healthy agro-ecosystem contributes both directly and indirectly to agricultural production, and more emphasis should be placed on restoring and maintaining healthy agro-ecosystems.
On pasture-based farms, the roughage grown on pastures is the predominant feed source. It is therefore most beneficial to grow and utilise these pastures effectively.
There is a lot more nutrient cycling taking place than just what is put into the soil through fertiliser, and taken out in grass and eventually milk. In order to develop a more efficient nutrient cycling system, farmers have to take into account the various losses and sources of nutrients.
