\"Protonic<\/figure>\n<\/div>\n<\/div>\n\n\n\n

Protonic\u00ae<\/sup> Quattro <\/strong>is a holistic biostimulant<\/strong> developed within Agrology’s Functional Crop Nutrition\u00ae<\/sup><\/em><\/strong> framework. Formulated as a soluble liquid, it combines high-concentration seaweed extracts with L-amino acids, carboxylic acids, and trace elements to support plant performance across all growth stages, from establishment to harvest.<\/p>\n\n\n

Composition<\/h4>\n\n\n\n
<\/div>\n\n\n\n

Protonic\u00ae<\/sup> Quattro is built on four active components<\/strong>, each contributing a distinct and complementary mode of action:<\/p>\n\n\n\n

Seaweed Extracts (50%)<\/strong> \u2014 equal parts Laminaria digitata<\/strong><\/em> and Ascophyllum nodosum<\/strong><\/em>, cold-processed to preserve the full spectrum of bioactive compounds. Seaweed extracts are a natural source of cytokinins, auxins, gibberellins, polysaccharides, and secondary metabolites that regulate plant metabolism and activate endogenous defense mechanisms against both abiotic and biotic stress.<\/p>\n\n\n\n

L-Amino Acids (20%)<\/strong> \u2014 derived from enzymatic hydrolysis of plant proteins, providing the only form directly absorbable by plants. Foliar application allows immediate uptake and rapid translocation, supporting protein synthesis, chlorophyll production, root development, and plant recovery from stress events.<\/p>\n\n\n\n

Carboxylic Acids<\/strong> \u2014 low molecular weight organic acids with strong absorption and rapid movement within plant tissues. They increase osmotic pressure, improve nutrient and sugar transport to target organs, and enhance the overall quality of the harvested product.<\/p>\n\n\n\n

Molybdenum (Mo) and Cobalt (Co)<\/strong> \u2014 two trace elements with distinct and essential roles in plant nutrition. Mo is a structural component of nitrate reductase and nitrogenase, the key enzymes in nitrogen assimilation and fixation. It also acts as a cofactor in the synthesis of abscisic acid (ABA) and auxins, and improves phosphorus availability through synergistic anionic complexation. Co is an essential component of vitamin B12, supports nitrogen-fixing bacteria in legumes, inhibits ethylene-induced senescence, and contributes to drought tolerance.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Functional Crop Nutrition\u00ae<\/sup><\/em> Effect<\/h3>\n\n\n\n
<\/div>\n\n\n\n

As part of Agrology’s Functional Crop Nutrition\u00ae<\/sup><\/em> approach, Protonic\u00ae<\/sup> Quattro acts as a holistic biostimulant that simultaneously nourishes and fortifies the plant. Its synergistic action promotes nitrogen assimilation and phosphorus uptake, regulates cellular processes that drive plant metabolism, and primes the plant’s capacity to recover from abiotic and biotic stress events.<\/strong><\/p>\n\n\n\n
