Micronutrients in soybean culture in direct plantaining systems in closed soils
The essential micronutrients, nickel, cobalt and molybdenum, provide a better use of nitrogen because they are important for the metabolism of this nutrient, and the use of these with conservation practices such as no-tillage, yield gains in soybean yield. The objective of this study was to evaluate...

The essential micronutrients, nickel, cobalt and molybdenum, provide a better use of nitrogen because they are important for the metabolism of this nutrient, and the use of these with conservation practices such as no-tillage, yield gains in soybean yield. The objective of this study was to evaluate the effect of the application of Ni, Co and Mo on the characterizes of soybean production, to evaluate the appropriate time for the supply of important micronutrients to the BNF process in areas with no-till systems of three and 15 years. The experiment was conducted in two areas of no-tillage system, three and 15 years old, in the experimental area of the Federal Institute of Triângulo Mineiro, Uberaba-MG. The experimental design was a randomized block design with four replicates in a 4 x 2 + 1 factorial treatment, in which the first factor consisted of a product based on nickel (Ni), cobalt (Co), molybdenum (Mo), denominated In the present work as NiCoMo, in the percentage 2,4; In the treatment of seeds (TS) and the vegetative stage, the second factor was the application mode, in the treatment of seeds (TS) and in the vegetative stage ( V3).
