Natural Farming Research
Studying Soil, Biology, Crops and Farm Systems Through Evidence
Soil Health • Microbial Ecology • Nutrient Cycling • Biodiversity • Water • Crop Performance • Farm Economics
Natural farming is more than the use or avoidance of a particular agricultural input.
It is a farm-system approach that places greater emphasis on soil biological processes, organic matter, locally available resources, crop diversity, ecological interactions and reduced unnecessary dependence on external inputs.
But agricultural systems are complex.
A practice that performs well under one soil, crop, climate or farming condition may produce different results elsewhere.
For this reason, Sansar Green approaches natural farming as an important field for scientific investigation, measurement and long-term learning.
Our research philosophy is:
OBSERVE → MEASURE → COMPARE → UNDERSTAND → VALIDATE → IMPROVE
The central research question is not simply:
“Does natural farming work?”
The more useful questions are:
What works?
Why does it work?
Under which conditions?
For which crops?
Over what period?
At what cost?
What changes in the soil?
What changes in the farm?
What limitations remain?
