The use of trace elements and powders of metals (iron, zinc oxide, cobalt) and humic acids for soaking seeds before sowing the clover and subsequent spraying with microelements (boron, molybdenum, a mixture of boron with molybdenum), is a cost-effective technological methods of increase of productivity, net profit, profitability of production and reduce the cost of production. So soaking in a 0.05% solution of the iron nanopowder of clover seeds and re-spraying in the budding phase trace elements, yield increases of 1.43 (Mo), 1.79 (В), 2.78 (В+Mo). Profit increases, respectively, at 14-27 thousand/hectares cost per quintal of seeds decreases by 627-1070 rub., while profitability reaches 200-248%.
