The COVID-19 pandemic has changed education. In these circumstances, technology aided learning by providing new ways of teaching and communicating with students. In this work, we report the online activities carried out in the Basic Organic Chemistry virtual course of the Chemistry Department at UNS (Argentina) for first-year students of the…

The soil science and soil chemistry is incorporated into teaching materials for earth day and beyond. It revealed some of the chemical properties of the soil through color and texture and the chemical processes relevant to soils abound, including the carbon and nitrogen cycles in the soil, acidification of soils through acid deposition, leaching…

An experiment was performed on polymeric-based controlled-release agrochemicals that minimize leaching into groundwater while maintaining an adequate quantity for the desired agrochemical benefits. Gelatin gel containing inorganic Phosphorous provides controlled-release of an agrochemical where release curves show a linear relationship between…

Describes a laboratory exercise for undergraduate science students in which they evaluate soil samples for various parameters related to suitability for crop production and capability for retention of contaminants. (Contains 18 references.) (WRM)
