Nitrogen compounds like nitrates (NO3?) and nitrites (NO3?) play a key role in mushroom growth, substrate quality, and contamination control. Imbalanced nitrogen levels can lead to problems in cultivation. Indigo® Nitrite-Nitrate test strips measure nitrite in 0 to 25ppm & nitrate in 0-500ppm levels. Nitrate reduces to nitrite and these test strips can help determine rates of nitrification, nitrite removal & biological oxygen demand.
Mushrooms need nitrogen for protein synthesis, enzyme production, and cellular metabolism. Nitrates (NO3?) are a key nitrogen source for some fungi, while others rely more on organic nitrogen (e.g., amino acids from composted materials). Excess nitrates can slow mycelium colonization, making it difficult for mushrooms to compete with bacteria and mold.
