The improvement of soil quality by using bio-fertilizers for medical and aromatic plant crops

Abstract

Soil is the basic support of plant growth and such the development of life on Earth. Over time, agriculture was developed according to the requirements of humanity, so cultivated soil surfaces have expanded increasingly more. This has become a strain on production capacity of the soil, which led to a decrease in its physical and chemical qualities. Concluding that in the 21 st century the concern for human health and the environment it is a must, this paper has in view the improvement of soil quality for growing medicinal and aromatic plants regarding the major macronutrient content (NPK). For that action it has been used 3 different types of bio-fertilizers (nearing of the forest, vegetal wastes and peat of conifers forest) in order to improve the soil quality and so there could be obtain higher quality crops of medicinal and aromatic plants.
