Efficacy of natural aluminosilicates in moderating drought effects on the morphological and physiological parameters of maize plants (Zea mays L.)
Natural aluminosilicates, zeolites and phyllosilicate clays are widely used in agriculture as additives to animal nutrition and as fertilizers for soil conditioning and remediation. Antitoxic nutrient (ATN) is a unique combination of naturally-occurring phyllosilicates, zeolite, bentonite and activa...
