Micronutrients are essential elements required by organisms in varying quantities throughout life to orchestrate a range of physiological functions to maintain health.
Micronutrients are one of the major groups of nutrients your body needs. They include vitamins and minerals. Vitamins are necessary for energy production, immune function, blood clotting and other functions. Meanwhile, minerals play an important role in growth, bone health, fluid balance and several other processes.
Topic PDF to print. Fertile garden soil is essential to obtain the best growth and productivity from vegetables and flowers. Plants need different amounts of seventeen essential elements to grow. Soils are rarely fertile enough to supply adequate quantities of all the elements needed for best plant growth.
Most soils do not contain enough Nitrogen for optimum plant growth. Vegetables and other shallow rooted plants also usually grow better with additional Phosphorus and sometimes Potassium. These three elements, and any other elements that a soil may lack, can be supplied with an appropriate fertilizer and compost.
Fertilizers may be either organic or inorganic often called chemical materials. Compost and similar organic amendments are a source of plant nutrients, but usually do not provide enough Nitrogen for optimum plant growth. Plants require seventeen essential elements for growth. If any one of these elements is missing, a plant will not grow, even if all the other elements are present in their required amounts. The elements which plants require in relatively large amounts are called macronutrients.
Nitrogen promotes green leaves and foliage growth. Phosphorous stimulates healthy root growth and helps with the formation of flowers, seeds, and fruit. Potassium is required for proper development of flowers and fruit, ensuring good size, color, and quantity. Commercial fertilizers show the percentage of these three nutrients on the label.

Essential elements which plants need in relatively small amounts are called Micronutrients. Composting organic matter such as grass clippings and tree leaves is an excellent way to provide micronutrients.

Micronutrient Requirements for Green Plants, Especially Algae
Plants meet their nutritional needs for growth by absorbing soil nutrients, water, and carbon dioxide, in addition to the required sunlight. Plants are unique organisms that can absorb nutrients and water through their root system, as well as carbon dioxide from the atmosphere. Soil quality and climate are the major determinants of plant distribution and growth. The combination of soil nutrients, water, and carbon dioxide, along with sunlight, allows plants to grow. In order to develop into mature, fruit -bearing plants, many requirements must be met and events must be coordinated. Take for example the Cucurbitaceae family of plants that were the first cultivated in Mesoamerica, although several species are native to North America. The family includes many edible species, such as squash and pumpkin, as well as inedible gourds.

Through increased use of soil testing and plant analyses, micronutrient deficiencies have been verified in many soils. Some reasons limiting the incidental additions of micronutrients include:. High-yield crop demands remove micronutrients from the soil.
Algae and Man pp Cite as. The growth and normal biochemistry of green plants require the availability of from 15 to 20 elements. Eventually still others may be added to the list.
