Stonemeal: Invest in a good idea
Stonemeal is pulverized stone, a common by-product in the mining industry. It has no large-scale application and is commonly found stockpiled at mining sites. The ‘meal’ contains valuable crop nutrients like potassium, magnesium, calcium and a variety of micronutrients that can be used as fertilizer. Some stonemeal mixtures help sequester carbon and retain water in the soil.
The documentary ‘Remineralization in Brazil’ shows how some farmers managed to increase their yields (by up to 30%) and the nutritional value of their crops with stonemeal. At the same time, they could lower their input costs and increase their farms’ profitability.
Many aspects of the Brazilian success story are relevant to and applicable in other countries. In Ethiopia, for example, few farmers can afford the fertilizers available in the market. At the same time, it is possible & economical to source stone meal and organic ingredients that together make for good fertilizer: such as straw, cow dung, rainwater, sugar, yeast and ash.
MetaMeta Circular Economy and its partners are working towards spreading awareness about Stonemeal among small-scale farmers in Ethiopia, training them in making stonemeal-based fertilizers on their own, and supplying the necessary raw materials to those who cannot access them. The efforts aim to improve the profitability of small farms and the well-being of small farmers, like what happened in Brazil.
If you think this is a good idea, you can be a part of it too. You can support the effort by donating money (with donations more than 25 Euros, you get up to 100 25L bags of Olivine stonemeal!), or with information and ideas about collaboration (write to email@example.com)
