The presence of beneficial fungi in the soil has been shown to significantly inhibit the growth of weeds. This is because beneficial fungi secrete acidic enzymes which lower soil pH. The reduced pH levels inhibit the ability of nitrifying bacteria to transform ammonia, one form of nitrogen, into nitrates, a second form of nitrogen that is vital for weeds to flourish.
