The goal is to restore agricultural soils to a healthy state – every farm is different, but the principles always apply.
I hope this case study encourages farmers who are in the process of adapting their management in order to achieve greater nitrogen fertiliser efficiency.
Sufficient, good quality pasture is fundamental to sustainable pasture-based dairy farming, hence the importance of optimal grazing management.
The relationship between plants and water is delicate. Too little water can lead to plant stress, resulting in wilting. Too much can lead to risk of pathogen infection and loss of nutrients supporting the plant via leaching.
Rebecca Burgess, founder of the Fibershed project says that, “our soils have a carbon debt; the atmosphere is gushing with carbon. The carbon over our heads is literally in the wrong place” and this couldn’t be truer.
True sustainable, regenerative agriculture will reverse the negative impact of conventional agriculture and result in sustainable food production.
These are some questions I was asked by a farmer in the Tsitsikamma the other day about legumes and root nodules.
Nitrogen-fixing bacteria in the soil provide an opportunity for farmers to tap into the huge amounts of nitrogen which are just sitting in the atmosphere, waiting to be unlocked.
The amazing thing is that all these ecosystem services support greater agricultural production. They can only be unlocked when the soil is viewed as a valuable natural resource that needs to be conserved.
Taking all this into account, methane is a huge problem. But is it? Recent research has challenged whether methane should be treated in the same manner as carbon dioxide when it comes to its impact on climate change.
