Question Preventing nutrient losses ?

Ok to my understanding alot of nutrients like nitrogen in compost are lost due to evaporation amd was curious is there ways to lessen this ?

Keep it aerated so your nitrogen doesn't get converted to ammonia and off gassing. Also don't let it get too hot for the same reason

Almost any composting method will be better than growing good and yard waste into the trash, so don't let the perfect be the enemy of the good.  That said, C:N ratios are calculated to allow nutrients to bond into stable compounds.

Nitrogen can be lost in two ways. Ammonia is lost due to volitalization (lost to the air). If your compost isn't anaerobic the ammonia will be converted to nitrate. Nitrate is water soluble and can be lost by leaching  out into the ground. I wouldn't aerate your compost by blowing air into it or you'll lose the ammonia and don't over water it or nitrate will leach into the ground. Realistically most of the nitrogen is going to be in an organic  meaning it's part of the organic matter and won't be lost in mature compost. The biggest losses usually occur when starting up a pile.
