Due to the environmental issues that conventional fertilization is causing, biostimulants are proposed as environmentally friendly alternative for crop nutrition in agriculture. The aim of this study was determine effects new Micro Carbon Technology (MCT®) fertilizers with biostimulant activity based on humic acids biologically digested from leonardite pepper plant growth three different soils ...

Soil acidification in the subtropical region reduces soil productivity and increases bioavailability of heavy metal(loid)s soil. Here 800 °C-calcined oyster shell leonardite-derived humic substance were combined to form a Ca-humic complex remediate an acidic contaminated by cadmium (Cd) arsenic (As) for safe vegetable production. In pot experiment, was added as amendment at 0%, 0.5%, 1.0%, 2.0%...

In this work, we have developed a simple method to carry out the quantitative analysis of deethylhydroxyatrazine (DEHA), most abundant metabolite atrazine herbicide (ATZ), based on surface-enhanced Raman scattering technique. Since ATZ product can undergo pH-dependent tautomerization, previous characterization DEHA vibrational spectrum was accomplished. This study consisted study, both experime...

Producers in semi-arid and highland regions have difficulty increasing diversity crop rotations due to unfavorable conditions imposed by cool temperatures, inadequate rainfall, shorter growing periods. In such conditions, some cultural practices that increase productivity as fertilization appear a promising alternative. Fertilization the form of fertilizer substantial influence on sunflower (He...
