Give scientific reasons:
$(1)$ Hydroponic method is most suitable for plant culture.
$(2)$ Soil is known as reservoir of mineral elements.

(N/A) $(1)$ In hydroponics,mineral nutrients are provided in adequate quantities,and water is utilized according to the plant's needs. This method provides protection against soil-borne diseases and ensures total freedom from weeds. It allows for efficient energy use and ensures the plant receives a balanced supply of mineral elements.
$(2)$ Soil contains various types and sizes of particles,such as sand,silt,and clay. Clay particles (colloids) are particularly important as they participate in the exchange of positive ions (cations) on their organic and mineral surfaces. Furthermore,soil acts as a medium that stores and releases many essential elements to plants. Thus,soil acts as a reservoir of mineral elements.
