Aluminum is one of the most common elements in the Earth's crust, playing a fundamental role in soil formation processes and the chemical weathering of minerals. For an agronomist, understanding the geochemical properties of this element and the patterns of its migration in landscapes is of practical importance, as aluminum is closely linked to the formation of the soil solution reaction. The state of the soil environment, in turn, directly determines the availability of nutrients, the effectiveness of mineral fertilizers, and the overall productivity of agricultural crops.
In this selection, we examine not only the natural content of aluminum in the soil cover but also related issues of soil nutrition. Readers will find materials on the role of various microelements and chemical processes in the soil solution, as well as analytical articles on the history of agrochemistry and the properties of phosphate fertilizers. A separate block is dedicated to methods of regulating soil acidity, which is a key factor for managing soil fertility. The materials also touch upon technical aspects of using aluminum structures in agriculture and issues of rational natural resource management under conditions of limited global resources.
