Know before you buy
Down To Earth Calcium 96 is an ultra-fine 325 mesh powder, which is significantly finer than standard Ag lime. This allows it to react much faster in the soil and makes it suitable for liquid applications like drip irrigation or sprayers.
Yes, the 325 mesh particle size is designed specifically for efficient delivery through irrigation systems. However, it is always good practice to ensure your system has proper filtration and to agitate the solution thoroughly before application.
Because of its high neutralizing value and fine texture, this product is highly reactive and will adjust soil pH much faster than traditional granular lime. You should monitor your soil pH levels closely after application to avoid over-correcting.
This product is an excellent calcium source for most plants, but it is primarily intended for crops that thrive in neutral to alkaline soil conditions. Since it raises pH, avoid using it on acid-loving plants like blueberries, azaleas, or rhododendrons.
Because this product is more concentrated and reactive, you can typically use lower application rates than you would with standard agricultural lime. Always perform a soil test first to determine the exact amount needed for your specific soil requirements.
