Impact of substrate pH and micronutrient fertility rates on Cannabis sativa

Agrosystems, Geosciences &Environment, Volume 8, Issue 1, March 2025.
Abstract Micronutrient accumulation caused by low pH can lead to toxicity and have detrimental impacts on plant growth. In substrates with elevated pH, micronutrients become less available. In the first experiment, industrial hemp (Cannabis sativa L.) growth was less at pH 3.0 and 4.0 than when pH was ≥5.0. Root growth was also observed to be inhibited
