History of organic cultivation
|
Farming started 12,000 years ago, at the end of the last ice age. The increasingly warmer climate enabled people to start growing crops for themselves and to remain in the same location for a longer period of time. This enabled us to finally move on from the insecure lifestyle of hunting and collecting. This resulted in the first civilisations (Syria, Mexico and China).
Of course people realised that a plant would grow better if you mixed fertiliser through the soil, but the reason why was not known. Back then we did not know anything about nutritional elements.
It was Justus von Liebig who showed the relationship between nutritional elements and plant growth in 1838 through experimental research. Eventually this has led to the introduction of fertilisers; a true revolution in farming. The use and working of the elements NPK was applied with variable success. Nitrogen (N) was obtained from coal tar. Phosphorus (P) could be obtained from bones. Potassium (K) was found as raw material in the mines of Chile and India.
