Calcium occupies a central place in the mineral nutrition system of crops, exerting a direct influence on their development and yield. For agronomists and crop practitioners, it is not only the presence of the element in the soil that is of key importance, but also an understanding of the physicochemical processes that determine its availability to the root system. The effectiveness of calcium fertilizer is closely linked to the acidity level of the soil cover, as well as to methods of their proper application, which ensure an optimal balance of nutrients.
This collection gathers materials that help identify signs of calcium and magnesium deficiency, which is critically important for preventing the stunting of plant growth. Readers will find information on the specifics of using nitrogen-calcium fertilizers, such as calcium cyanamide, as well as on methods for diagnosing soils and substrates. The articles cover a wide range of issues: from the regulation of mineral nutrition in potatoes and vegetable crops to practical recommendations for the application of fertilizers depending on the biological characteristics of the cultivated plants and the specific soil properties.
