Calcareous soil contains calcium carbonate and is characterized by alkalinity and a certain hardness. This soil is suitable for specific crops that tolerate alkalinity, such as olives and citrus. However, it is poor in some essential nutrients for plants, so pH adjustment and fertilizer addition are necessary. Calcareous soil provides good water drainage and supports plant roots firmly. Its fertility can be improved by adding organic matter and natural fertilizers. This soil is common in dry and rocky areas and provides a suitable environment for some alkaline-tolerant crops. It helps reduce salt accumulation and maintains the balance of nutrients in the soil. Calcareous soil supports plant growth if managed properly. It can be cultivated in gardens and small to medium farms. It provides a stable environment for microbes that improve soil quality. It is an economical choice for farmers in arid regions. Preserving its fertility ensures high crop productivity. Calcareous soil plays an important role in sustainable agriculture and environmental protection.
