We promote sustainable and soil regenerative agricultural practices with particular emphasis on conservation agriculture.
We assist with the regenaration of over worked and degenerated soils.
We provide analytical services that:-
Measures the health status of soils.
Provides an indication of the readily accessible quantity of plant available nutrients.This is not the same as that analyzed from a conventional chemical soil extracted analyses with strong acid or alkaline bases that is in most instances not always accessible to the crop plant root system. Our nutrient analytical test method is based on the Haney Soil Health Test method which includes the Solvita, 24 hour CO2-C burst test.
These analyses will provide the status of the available nutrient resources which can be taken into account in the required nutrient calculations for the next crop.
We assist in conservation agriculture research projects.

Soil Biological Indicators
Exploring some soil biological indicators. Grain SA contribution “Year of the Soil”.
Our basic philosophy of soil health and the ability of a healthy soil to provide a profitable substrate for a commercial farming operation is briefly summarized below.
The average arable soil contains enough natural minerals to farm most commercial farming enterprises without any external chemical inputs extremely profitably. This may not be achieved in one year but with the correct biological approach it can be achieved in a shorter period than most people think and is being achieved by more and more farmer’s worldwide.
Some farm lands may never be able to achieve this ultimate goal but should at least establish its limiting factors within a potential conservation agriculture approach rather than continue on the path of a complete chemical and conventional tilling dependency; the benefits from such a system cannot be quantified in financial terms, because this is a continual asset regeneration process.
There are literally millions of “starving & unemployed” microbial communities in most soils willing to work for food only without pay. They are prepared to provide the crop plants with all the nutrients in exchange for food from photosynthate exuded through the roots of cover crops. They only need to be fed.
There is a microbial system in play for the provision of every nutrient required for plant growth, that can be obtained from the naturally occurring soil minerals.
Combine the atmosphere nitrogen, which is a staggering 78 percent with the numerous free living nitrogen fixing bacteria and fungal combination systems in a soil and this can take care of most of these needs in way provided by nature free of charge
We do not propose the complete elimination of external inputs in the form of chemicals, or the breaking of a hard pan by ripping, should this be required, but the overall objective should be to limit these practices only when absolutely necessary or where the natural providing process is limiting.
There is a common thread that runs through all the very successful conservation farming operations and is the following:-
Achieving and maintaining a healthy regenerative soil of which the key elements are the following as practised and proclaimed by Mr Gabe Brown :-
- Least amount of soil disturbance.
- “Armor” on the soil surface at all times.
- Plant diversity – 20 to 50 cover crop mixes.
- Living roots as long as possible.
- Integration of livestock on cropland.
