Phosphorus is identified as a key macronutrient required for the cultivation of industrial hemp [1], with research specifically examining the effects of phosphorus fertilization on its growth, fiber quality, and yield {fact:2, fact:3, fact:8}. Furthermore, specific fertilization guidelines and comparative requirements for phosphorus application in industrial hemp production have been established in scientific studies {fact:5, fact:6, fact:7}.

claimScientific conclusions regarding the effects of potassium and phosphorus fertilization on industrial hemp are mixed.
claimPhosphorus fertilization affects industrial hemp plant height, tensile strength, and elasticity of bast fibers, but does not affect grain, stem, or biomass yield.
measurementRamie requires 525 kg/ha of nitrogen, 140 kg/ha of phosphorus, and 525 kg/ha of potassium fertilizer for maximum yield, which are higher requirements relative to industrial hemp.
referenceVera et al. (2006) studied the effect of nitrogen and phosphorus fertilization on the growth, seed yield, and quality of industrial hemp in the Parkland region of Saskatchewan, published in the Canadian Journal of Plant Science.
referenceAubin et al. (2015) studied the response of industrial hemp to nitrogen, phosphorus, and potassium fertilization.
claimThe quality and yield of industrial hemp bast fiber are affected more by potassium than by phosphorus.
claimThe key macronutrients required for growing industrial hemp are nitrogen, potassium, and phosphorus, according to Wylie et al. (2021).
measurementP2O5 fertilization for industrial hemp should not exceed 22.4 kg/ha of phosphorus, as exceeding this level significantly increases hemp seed mortality rates.
