We did not need this research to give us confidence in the principles we advocate for in terms of nitrogen fertiliser management on dairy pastures. But it is encouraging to see other research which confirms what we have been observing.
The purpose of this article is purely to provoke thought. To ask you to consider where you fall in the spectrum of techonogist and environmentalist, and to think about how this perspective influences your view of the solutions that are presented to you every day.
The main culprit, of nitrous oxide emissions, in agriculture is the excessive use of synthetic nitrogen fertilisers. Fortunately, that is something farmers can do something about.
Transpiration depends on evaporation, therefore factors affecting the rate of evaporation also affect the rate of transpiration.
Soil fungi increase security, awareness, and knowledge for those connected to them. Any soil management action that results in the breakage of these connections, such as tillage and fungicides, destroys the entire nerve system of the soil thus isolating plants and soil organisms from each other.
Effluent may be a waste product generated on dairy farms, but it can be a valuable resource when disposed of correctly and in the right places.
Weeds are a nuisance but through effective field management, herbicide usage, and cover crops they can be controlled.
Global warming has had a drastic impact on nature and one of its biggest hits has been on water availability. Of all the water on earth, 2.5% is fresh water and only 1% is available for use.
Attaining soils that are working for you is a process. It starts with figuring out where your soils currently are. This will determine the next steps.
