The rhizosphere represents a fascinating and complex system, which plays a crucial role in the functioning of the soil ecosystem and the health of plants. This zone is characterized by an intricate web of biological, chemical, and physical interactions between the plant, the soil microorganisms, and the soil itself. One of the key functions of the rhizosphere is to facilitate nutrient uptake by plants, by enhancing the availability and accessibility of nutrients in the soil. Another important role of the rhizosphere is to mitigate plant stress, by providing a range of protective and supportive functions. Understanding the mechanisms underlying nutrient cycling and stress response in the rhizosphere can help us to develop more sustainable and efficient agricultural practices, which can improve soil fertility and plant productivity, while minimizing environmental impact.
Manure is both a waste product with the potential to pollute, and a potential fertiliser. One challenge in dairy production is managing manure in a way that is advantageous for agricultural production, while minimising the potential negative impact on the environment and public health.
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.
Compost tea, if used correctly, can help reduce the use of harmful pesticides through the introduction of beneficial microbes and at the same time bring nutrients that are essential for plant growth and soil functions.
How low have farmers been able to come with nitrogen fertiliser rates, while still maintaining optimal pasture growth?
The take-away challenge is for farmers to assess whether their fertiliser costs are decreasing per pasture produced. Are you growing cheaper pastures?
Nothing should ever be viewed as “waste” on the farm. Organic waste can be converted into compost that helps improve the farms soil life and fertility.
When dairy effluent is viewed as waste water, it is all about getting rid off it. However when it is viewed as beneficial water, it is all about the opportunity costs of the nutrients.
As a farmer, you can contribute negatively or positively towards the problem of freshwater pollution. If you want to make a positive contribution, what practices are you implementing to do so?
Nitrogen is a nutrient that is crucial for the optimal growth of plants. Its role in plant health may very well be unparalleled, but what happens when it becomes excessive in the soil? Is it “the more the better”, or rather a case of “too much of a good thing”?
