Medir clorofila puede apoyar decisiones de fertilización nitrogenada plantas. Usando un dispositivo impreso en 3D y LED rojo, aquí probamos la factibilidad usar teléfono celular para estimar por transmisión luz. Al comparar 30 lecturas trasmisión luz roja (663 nm) hojas sorgo Sorghum bicolor (L.) Moench, obtenidas del espectrómetro estándar, se encontró buen coeficiente determinación (r2 = 0.9067). Adicionalmente, hizo una comparación entre las SPAD 502TM (un comercial estimación contenido...
Gold phytoextraction is a technology used to obtain this metal (Au) throughout plants. Some of the benefits are mitigation environmental impact, fact that it does not imply constant use pollutants, and has ability promote soil reclamation. The aim research was determine if Brachiaria decumbens potential improve physical properties while had achieved gold extraction. For purpose, Helianthus annuus decumbens, were in completely randomized design with four replicates. To induce uptake, ammonium...
