Nitrogen as a limiting nutrient
    #2349768 - 02/18/04 01:08 PM (12 years, 9 months ago)

All fungi need a suitable supply of organic nitrogen, ie. peptone. Some can make use of NO3- or inorganic nitrogen.

In growth on BRF or grains is Nitrogen a limiting nutrient? I can't find any reference to the addition of organic nitrogen or inorganic nitrates as nitrogen supplements.

Does anyone enrich soils with nitrogen or with vitamins like thaimin and biotin?

IS their a way to determin the amounts of nitrogen to be added to soils if it is a limiting nutrient? I can't seem to find any literature on this.

Too much nitrogen will increase the chances of a contaminant taking hold (more nutrients for shrooms means more nutrients for other things which might not normally have quite enough or the right type for robust growth on your substrate). That being said, I've used a small amount of a type of yeast nutrient (di-ammonium phosphate) from home brewing supply stores in liquid cultures made with extra light malt extract. This really seemed to increase the growth rate of the mycellium.

To call humans 'rational beings' does injustice to the term, 'rational.'  Humans are capable of rational thought, but it is not their essence.  Humans are animals, beasts with complex brains.  Humans, more often than not, utilize their cerebrum to rationalize what their primal instincts, their preconceived notions, and their emotional desires have presented as goals - humans are rationalizing beings.

I was thinking more along the lines of post colinization. After full colinization perhaps adding moisture to the casings that had nitrogen in it or other nutrients as well. I may experiment with it a bit to see if it makes a difference.

I'm interested if the food source would run out before essential nutrients.

So your saying to rehydrate the casing with a fertilizer. My idea a while back was to do a manure tea dunk after pasturizing the tea. Everyone said that contams would be a problem but if the casing is 100% colonized it wouldnt give the contams a place to take hold.
