Lime is Calcium Carbonate and Calcitic lime is just Calcium, CaCO3. Dolomitic lime is Calcium and Magnesium, CaMg(Co3)2. If your soil is in need of Magnesium then you need to apply dolomitic lime, but if the soil test indicates ample reserves of Magnesium but insufficient reserves of Calcium what you need is calcitic lime. Lime slowly reacts in soil unless you get hydrated lime. This is why the best time to apply lime on your soil is in the autumn, especially if it is mixed with humates! Applying in the spring will not harm anything but there will not be much change in soil pH for several months.
Mixing humates with lime is very beneficial for soil
Humates (both raw humates and soluble humates) bond ions of Ca and Mg first, which increases Cation Exchange Capacity (CEC) and prevents the formation of insoluble phosphates in soil. CEC is important because it represents the primary soil reservoir or readily available Potassium, Calcium, and Magnesium and several micronutrients. It also helps to prevent their leaching. The ease with which a plant gains access to these nutrients depends somewhat on the relative percentages of the adsorbed cations. For this reason it is suggested that the percentage saturation levels be held within loosely defined ranges. For example, a soil with base saturations of Calcium 70%, Magnesium 12%, and Potassium 4% would be considered balanced for most crops and has a soil pH of about 6.5. Humate mixed with dolomitic or calcitic lime could help to adjust your soil to this optimal level.
