Viticulture and dairy are two of the best areas of agriculture for revealing the virtues of biodynamic growing — viticulture because quality is what wine excellence is all about and dairy because every tank of milk is tested for quality. Biodynamics is about quality and self-sufficiency. Both depend on life force to attract nitrogen from the atmosphere rather than using nitrogen fertilizers.
Chemical agriculture is largely a 20th century phenomenon based on the great 19th century chemist, Justus von Liebig’s premise that plants only take up nutrition as soluble salts — an assumption he repudiated toward the end of his life. However, by then the fertilizer industry was making great strides by capitalizing on his error.
The shortcomings of ‘chemical’ agriculture became the starting point for biodynamic agriculture and was why Rudolf Steiner introduced his Agriculture Course in 1924. But, by then the chemical approach had become dominant with the discovery in 1909 of the Haber Process, which produced ammonia from natural gas and air. Meanwhile, biodynamic agriculture became pigeonholed and marginalized as a cult of true believers rather than a truly scientific method born ahead of its time. Continue Reading →
