It is shown that Saharan soil has the potential of producing bioavailable iron when illuminated with visible light and also it contains some essential macronutrient and micronutrient elements. In this study, these properties of the desert soil were tested on the certified wheat cultivars (Triticum aestivum L. var. gonen 98) using Hewitt nutrient solution, illuminated and non-illuminated soil so...

He quotes a judgement they formed on Donald Taylor’s (1948) book ‘Fundamentals of Soil Mechanics’ as a ‘theoretical and esoteric portrayal o...
