There is a huge issue in agriculture that most of the research, especially prominent research, is driven by the agrochemical agenda.
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.
These are some questions I was asked by a farmer in the Tsitsikamma the other day about legumes and root nodules.
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.
I would challenge any farmer that desires to improve their farm to think about the “why” behind the regenerative agriculture approach. What is the prize?
Often farmers treat the farm as a whole and that is completely wrong. Fields within a few meters from each other can have completely different characteristics, especially with regards to soil biology.
Oxygen is one of the overlooked but most important requirements for microbial and root development. In fact, I’d even posit that it is more important than food, water, and warmth.
To a large extent, these threats are caused by conventional agriculture. This is what makes the regenerative approach to soil management so important.
Keeping the soil covered is important for soil conservation. The abundance and diversity of food for soil organisms is what determines a soil’s natural productivity.
