A micro element to a plant is like a chip to a computer. As result of 60 years of N P K, our European
soils are exhausted. Nowadays farmers are aware of the importance if micro-nutrients to ensure production and Industry sells them in small jars. They are the most expensive input in agriculture.
In plants and animals micro nutrients are the key to endless enzymatic reactions, metabolic routes. They enable growth, development of flowers, fruits and seeds. The are not just an input to get quality product but there are essential to life. A decade ago this view was not so obvious.
First, industry created Urea, Phosphorus and Potash. After a few seasons, the first symptoms of crop deficiencies appeared. agricultural experts met. They agreed that calcium and magnesium and sulfur and silica were limiting the crop production. The market supplied, engineers calculated universities started to teach about these other “less important” elements.
Soon after, micro nutrients became the bottleneck. Iron, Zinc, Boron, Cobalt, Copper, Molybdenum, Selenium, manganese… Again the same response: Experts met, industry supply, sell and university teach to a new generation of micro element sensitive engineers.
Recent research points that the elements called rare earth elements play crucial role in the metabolism of plants and or symbiotic microorganisms. Experts are meeting again. Industry is prepared already and so do Universities. The tendency now is to consider that crops need all elements, but in each one in the right proportion. Many igneous rocks in nature have high diversity of mineral elements in secondary and micro nutrients and can serve farmers to re-mineralize their soils in a affordable way.
Rocking soils works with farmers to build capacity, develop and share the skills to extract plant nutrients from rocks and regenerate exhausted soils.
