Techniques for studying the mineral requirement of plants:
In 1860, Julius von Sachs, a popular German botanist, showed for the first time that in the absence of soil, plants could be cultivated to maturity in a given nutrient solution. This method of growing plants in a solution of nutrient element is known as soilless growth of hydroponics. After a series of experiments in which the plant roots were submerged in nutrient solutions and in which an ingredient was added or removed or given in different concentrations, a mineral solution suitable for plant growth has been obtained in different concentrations. The soil-free cultivation method is often referred to as tank farming since the plants are cultivated in large tanks. Knop first prepared the solution for the hydroponic culture. Knop solution, Hoagland solution, Arnon solution, and Sach solution are popular nutrient solutions. Hydroponic emphasizes on the essentiality of nutrients in minerals. The signs of malnutrition arose when specific nutrients are not available. The toxicity of the plant is observed when an ingredient is overly present. In areas such as poor, infertile, and dry soil, hydroponics is beneficial. It saves water and manages the optimal pH for a given crop, pests and disease.
Essential mineral elements:
Critical elements are called elements that are essential by plants for standard growth and development, and without which plants cannot complete their life cycle. In the plant body, approximately 50-60 elements are present, but only 16-17 elements are considered as critical elements. For instance- C, H, O, N, K, S, Ca, Fe, Mg, P, Cu, Mn, B, Cl, Zn, Mo, and Ni. Non-essential elements are called elements that are found in the body of the plant and are not needed by plants such as Na, Si, Al, Sa, Sr, According to Arnon, the requirements for the minerals to be critical are as follows: the element must be unique to the life of the plant and can be replaced by some other element which is indispensable to the plant; the elements have to be specifically active in plant metabolism, Arnon then separated these essential mineral elements into two classes. They are as follows:
Macronutrients: The concentration should be 1-10 Î¼g L-1/10 m mole kg-1of dry matter. For instance; C, O, H, N, Ca K, S, Fe, Mg, and P. Comparatively, significant quantities are needed.
Micronutrients: The concentration should be less than 1.0-0.1 Î¼g L-1/10 m mole kg-1 of dry matter. For instance; Cu, Zn, Mn, B, Cl, Mo, and Ni. Comparatively, they are required in smaller amounts. These elements are grouped based their features:
Biomolecule elements; For example; C, H, O, N.
Energy-related chemical compound elements, for instance, chlorophyll Mg and ATP phosphorus.
Essential nutrients, for example, potassium which plays an important role in the opening and closure of stomata.
When the mineral is present below the critical concentration, it is deficient. The concentration of nutrients below which the plant growth is retarded is called critical concentration. Deficiency Signs are highly evident in pathological disorders that are caused by any vital dietary material being absent or deficient. In plants, the signs of deficiency of highly mobile elements such as N, P, K, and Mg first occur in older plant sections. These minerals are present as structural constituents in biomolecules in mature plant components and are broken down as plant components get aged, making these components available to younger plant components. In young plant parts, the deficiency symptoms of immobile elements such as Ca, S are first to occur as they are not transferred from older plant parts.
