my question is what happens when we mine all the nutrients out of the lawn
with this type of program?

i know when i seed i add starter fert, lime or whatever the soil test calls 4.
most in my area dont do this at all.

we have been using n,p,k ferts for ever and now in most areas the p has been taken out of the fert to keep the waterways cleaner.
fert companies jumped on this because it makes there fert cheaper to make.

trucking and spreading bagged fert is costly and the organic products have gotten so costly its almost out of the reach of the common customer.

holganix is appealing due to its small space requirement to store it but should we be adding p and k somehow to keep the lawn balanced or is there an endless supply locked up in the soil.
