The global problem is that despite even the best efforts to eat a healthy balanced diet, most of our food sources no longer contain all necessary micronutrients, fulvic, humic and bio-active organic acids, minerals and other phytonutrients our bodies need to stay healthy because of soil degradation due to intensive industrial agriculture practics. Degraded soils cause poor nutrition value plants and poor nutrition value food cause human physical and mental degeneration. One of the ways to solve the problem is humic and fulvic acid preparations. The field experiment was conducted in 2016-2017 at the Rumokai Experimental Station of the Lithuanian Research Centre for Agriculture and Forestry on a Bathihypogleyi-Calc(ar)ic Luvisol (LVk-gld-w) with predominant silt loam on clay loam. Mineral Ful and Ferbanat L were tested in the experiment. Mineral Ful is a high bioactive fulvic complex with 33 organic acids, and over 70 micronutrients that is free of chemicals. Mineral Ful produced water extraction method of leonardite. Ferbanat L contain humic and fulvic acids, vitamins, amino acids, enzymes, micro and macro elements and beneficial soil microorganism. The preparation obtained by the result of the transformations of organic waste by used of the worms. Test preparations had the influence on humus content in the soil. Mineral Ful and Ferbanat L increased sugar beets root yield from 1.33 to 7.11 t ha-1. Cereal grain yield increased 2.6-1.,0 %.

The aim of this research was to identify the impact of soil microelements on sulphur absorption in the spring wheat. The field experiment was conducted in 2011-2015 at the Rumokai Experimental Station of the Lithuanian Research Centre for Agriculture and Forestry on a Bathihypogleyi-Calc(ar)ic Luvisol (LVk-gld-w) with predominant silt loam on clay loam. During the years the research has shown that the sulphur content in leaves and straw was positively influenced by these soil microelements: manganese (correlation coefficients of 0.973**, 0.98** and 0.959**, respectively), molybdenum (correlation coefficients of 0.977**, 0.955** and 0.929**, respectively) and zinc (correlation coefficients of 0.794**, 0.847**, 0.840**, respectively). Larger boron quantity in the soil reduced the sulphur content in the leaves of wheat (correlation coefficients -0.739**, -0.771**, -0.781**). The impact of soil microelements on sulphur content in the grains of spring wheat was not identified in this research. The sulphur content in the grains was strongly influenced by precipitation in June and July months.
