EM, vegetables, plant quality, symbiotic bacteria, nitrates.


EM microorganisms are able to increase the soil microfauna, leading to an improvement in field production. Photosynthetic bacteria, contained in Em microorganisms, can in fact, in synergy with other microorganisms, improve the absorption of nutrients from the soil and reduce the incidence of disease. The objective of this trial was to evaluate the influence of EM microorganisms on growth and nitrate content on pepper and chilli plants. The treatments carried out were: 1) use of EM microbial selection; 2) plants irrigated with water. In all the experiments carried out, the pepper and chilli plants treated with EM were significantly higher and had larger stems than those treated with water. The use of EM micro-organisms can therefore lead to an increase in production quality and a reduction in nitrate content on pepper and chilli plants.
