– Dolomitic lime is derived in the identical methodology nevertheless from limestone sources that comprise every calcium and magnesium.
In case your soil check out comes once more exhibiting extreme ranges of magnesium, use calcitic lime. If the check out displays a magnesium deficiency, then use dolomitic limestone. Pelletized varieties are less complicated to utilize and allow for additional uniform safety, and the equipment cost for pelletized lime is lower than for crushed. A 1:10 ratio is the rule of thumb. Which implies you need ten events a lot much less pelletized lime than crushed agricultural lime to garner the equivalent pH change.
