procedureThe procedure for mineral digestion involves digesting leaf samples in a 20 mL diacid mixture of HCl and HClO4 in a 4:1 volumetric ratio, bringing the final volume to 100 mL, and using the resulting extract to analyze Phosphorus (P), Potassium (K), Calcium (Ca), and Sulfur (S).
procedurePhosphorus in a plant digest is analyzed using the Canada-molybdate yellow color method, Potassium and Calcium are analyzed using a flame photometer, Sulfur is evaluated using a turbidimetric process, and Sodium, Zinc, Copper, Iron, and Manganese are determined using atomic absorption spectrophotometry.
measurementPotassium content in sampled plants was highest in Achyranthes aspera L. (1.46 ± 0.11) and lowest in Senegalia catechu (0.22 ± 0.11).
claimCommon minerals analyzed in medicinal plants include calcium, phosphorus, potassium, sulfur, and nitrogen, which contribute to bone health, immune function, enzyme activation, and antioxidant defense mechanisms.
measurementRybicka and Gliszczyńska-Świgło analyzed the content of calcium, potassium, magnesium, sodium, copper, iron, manganese, and zinc in grain gluten-free products in a 2017 study.
procedureMineral analysis of medicinal plants determines the presence of essential elements including sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn).
claimEssential minerals such as calcium, magnesium, potassium, and iron are present in the studied medicinal plants and contribute to promoting overall health and vitality.
A critical review of industrial fiber hemp anatomy, agronomic ... bioresources.cnr.ncsu.edu BioResources 6 facts
claimScientific conclusions regarding the effects of potassium and phosphorus fertilization on industrial hemp are mixed.
measurementHemp grains, which are edible seeds harvested for human or animal consumption, contain approximately 5.6% minerals (calcium, magnesium, potassium, and phosphorus), 25% protein, 28% total dietary fiber, and more than 30% oil.
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).
measurementFiber, grain, and dual-purpose industrial hemp require approximately 336 kg/ha of potassium.
claimPotassium uptake in industrial hemp increases with plant maturity, with the highest uptake occurring during the development stage of bast fibers, which causes significant increases in cellulose and hemicellulose content.

measurementBasil plants grown under a red-to-blue light ratio of 3:1 show accumulation of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and iron (Fe).
measurementAmaranth plants grown under red or blue light show accumulation of sodium (Na) and potassium (K) minerals.
measurementLettuce plants grown under red light show accumulation of potassium (K), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn).
measurementMustard plants grown under a blue-to-red light ratio of 1:1 show accumulation of phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), and boron (B).
measurementDill plants grown under red light show accumulation of phosphorus (P), potassium (K), calcium (Ca), and zinc (Zn).
referenceSuh et al. (2020) characterized metabolic changes in Perilla frutescens under conditions of low mineral supply (nitrogen, potassium, or magnesium) combined with supplemental LED lighting (red, blue, or red-blue combinations).

referenceTjhia et al. (2018) analyzed the correlations between leaf nitrogen, phosphorus, and potassium levels and the content of chlorophyll, anthocyanins, and carotenoids in bitter leaf (Vernonia amygdalina Del) during its vegetative and generative growth stages, published in the Journal of Tropical Crop Science.
claimVernonia amygdalina seeds contain vitamin C, vitamins B1 and B2, sodium, potassium, calcium, magnesium, iron, zinc, and manganese.
claimTraditional processing methods for bitter leaf (Vernonia amygdalina), including boiling, squeeze washing, and salting, result in the loss of proximate nutrients, calcium, iron, potassium, and vitamin C.
