Dutch Ferti Extreme Lime is an extremely effective lime because of the size of the calcium carbonate particles in the product. The particles found in Dutch Ferti Extreme Lime are more than 300 times smaller (< 5 µm) than conventional powder limes. It is because of this extremely small particle size that the pH-buffer of the soil is positively influenced instantly. Also, the very large surface area of de powder of Dutch Ferti Extreme Lime (as compared to conventional limes) makes sure that calcium is readily available for the plants immediately after adding it to the soil.
