Among the trace elements required for a normal growth of the plants, Manganese is important, playing a definitive role in the metabolism. Manganese is considered essential for the life of plants and animals. It could be called “bioessential” element. The aim of the paper is to present a study of total manganese in soil, wheat grain and wheat plants. The quantification of Manganese was done by the spectrophotometric method. A kinetic of Manganese concentration in the growing of wheat plants, in the soil with known Manganese content, for one month period was done. The total Manganese from the soil, from the initial wheat grain and wheat plants grown only in distillated water was established too. The concentration of NO3 – in the agricol soil has measured.
The total manganese (II) of wheat grain has been 330.696 ppm. After 10 days of grown it was noticed the manganese (II) content of wheat plants was approximately constant for two both situations: wheat plants in normal soil and wheat plants in distillated water.
This fact allows us to presume that the wheat plants in the first two-three lives weeks grown supported by wheat grain manganese (II) content. A very strong correlation between pH of soil and content of Manganese has been found. At the 7.24 pH-value of soil although the soil has high manganese content (478.903 ppm) still the content of manganese from the wheat plants is about 125 -140 ppm during the experimented growing period of plants. After one month of wheat plants growing, the NO3 – concentration of the soil is increasing from 21 ppm initial value up to 28.5 ppm and pH values of soil slowly decreased the values being 6.7 in the end of experiments.
