Minerals include copper, calcium, selenium, zinc, iron, iodine and chromium which are integral part of regular human diet.
These minerals are also known as “micronutrients” or “trace minerals” and are actually a result of natural ecological procedures that take place over a span of time.
These minerals are also gathered by the root system of the plants from the soil and enrich the fruits’ or vegetables’ nutritional value.
According to the testing and researches done by U.S. Environmental Protection Agency, average soil holds around 45 percent minerals which are absorbed by the plants. There are various types of soil which are used for various purposes and they are enriched with various minerals.
Garden soil holds the best balance between natural substances and mineral substances. This soil is mainly found in brown color and it is easy to manage. The natural substances which are present in this soil help it in holding its structure and value.
These natural substances also help the mineral substances to preserve their existence in the garden soil. The mineral substances are absorbed through clay, silt and the sand particles of the soil.
In addition to this, manure helps in adding quality to the soil and maintaining the structure and mineral substances inside the garden soil. Manure also provides extra nutrients to the soil which are absorbed by the plant’s root system in the form of minerals.
Clay is mostly found in the valleys or river bank sides. This soil is very sticky and it is found mainly into clusters.
Clay is very rich in minerals but lacks sufficient quantity of oxygen due to its compact structure. And it is due to this compact structure only that plants cannot be grown in this soil even though it is so rich with mineral substances.
The structure of this soil can be altered by adding organic materials like coarse sand or even compost.
Sandy soil is also known as rocky soil. This kind of soil is highly enriched with minerals but lacks the ability to give support to the root system of the plant.
According to the soil testing reports by Ohio State University, this soil can be improved with the help of soil conditioners, for instance, decomposed leaves, peat moss, saw dust, etc.
These substances help in binding the mineral nutrients which in turn increase the water retention ability of the soil. This helps the plant root system absorb the mineral substances and increases its nutrition value.
