NIR technology analyzers are already being used by cannabis growers to measure cannabinoids. Recently, a new plant tissue nutrition model was launched that measures macro and micro nutrients in dry cannabis leaves: the Valenveras Plant Tissue Nutrition Model. "It is similar to ICP (Inductively Coupled Plasma Spectroscopy), but by using NIR (Near-Infrared Spectroscopy) technology, it provides results in less than a minute," says Ruben Valenzuela, CTO of Valenveras. "It analyzes essential macro nutrients (N, P, K, Ca, Mg) and micro nutrients (Fe, Mn, Zn), enabling growers to optimize the nutrition plans for different cannabis cultivars."
Technology
Ruben explains that NIR is the technology behind the model. This method analyzes the absorption of light related to the vibration of organic molecules. "For testing, we collect two leaves from the middle height of the plant, dry them in an air fryer or oven for five minutes, grind them, and then test them with the Neospectra device using Valenveras models. Results are available in less than a minute."
The company developed its new Plant Tissue Nutrition Model because it believes in the importance of optimal plant nutrition to maximize the potential of cannabis plants. "Proper nutrition improves cannabinoid and terpene content and prevents problems and pests," Ruben says. "Many top producers send leaf samples to labs weekly to evaluate nutrient intake. By developing this model, we offer a tool for immediate, on-site analysis, eliminating the wait for lab results (2-5 days)."
Improving fertilization and research
According to Ruben, improving cannabis fertilization offers several benefits. First of all, increased production. "Optimal fertilization ensures plant growth, improving yield and quality of medicinal compounds like cannabinoids and terpenes. Studies show enhanced fertilization significantly boosts THC and CBD levels." Also, plant health is an important benefit. "Proper nutrient balance prevents deficiencies, strengthens plants against diseases and pests, and improves resilience to abiotic stressors like water stress and extreme temperatures." Importantly, it also helps with pest prevention. "Well-nourished plants produce more aromatic compounds (terpenes) that repel insects and pathogens, and optimal nutrient levels strengthen natural plant defenses."
Ruben adds that the new solution will also benefit cannabis research. "Our model allows for faster analysis of nutrient intake across various cultivars, aiding in the evaluation of the best strains for different climates and locations. This accelerates research and enhances the understanding of nutrient impacts on cannabis growth and quality."
