Microorganisms like fungi and bacteria use the carbon, nitrogen, and other nutrients in organic matter as food in order to obtain energy to survive. Microscopic soil animals like protozoa, amoebae, nematodes, and mites feed on the organic matter, fungi, bacteria, and each other for the same purpose.
Have you ever wondered what is going on beneath your soil? Do a basic visual soil assessment and compare it to the sustainability indicators in order to predict when soil quality starts deteriorating.
There is also a responsibility to being a land manager. Farmers are in a position to be stewards of the land that they manage.
Every farmer that I have presented a carbon footprint of their farm to has expressed a desire to reduce it over time. One of the main reasons for this is because a carbon footprint is actually an indicator of broader farm sustainability.

The majority of land in South Africa is owned by farmers. This makes farmers the true stewards of South Africa’s land.

Do you have large cracks in your soil? This could be the result of excess sodium. Read this blog to see the positive impact of gypsum application on excess sodium and an improvement in soil structure.
A supply of nutrients and minerals to soils which is greater than the amount needed to maintain soil health and fertility actually endangers the soil and can negatively impact on surface and ground water sources.
Energy is imperative to growth and sustenance of all animals, and plays a major role in the production of milk by a dairy cow.
