Abstract	This experiment objectified to evaluate the efficiency of different techniques of the organic management after the first year of transition seeking its insert in the family agriculture. The experiment was installed in august/2004 in a coffee crop located in Lavras/MG, (variety Catuai Amarelo, spacing 4,0 x 0,7m and 6 years) previously cultivated in a conventional management. Experimental design used was the lattice balanced 4x4 with five replications in factorial scheme 3x2x2 and four more additional treatments. Three sources of organic matter were used (castor bean bran, bovine manure and boiler litter) with or without straw of fermented coffee, and with or without the green manuring with (Cajanus cajan L.), in the line spaces of the coffee crop and pulverizations with the biofertilizer “supermagro”. The conventional management had the application of ammonium sulfite and the potassium chloride, and conventional foliar manuring. The effects of organic and conventional managements in the chemical attributes of the soil (0-20 cm) were evaluated after the first year of agroecologic transition. The organic management maintains an appropriate supply of K in the soil, with prominence for the boiler litter and bovine manure. The most significant benefit of the manuring organic in the soil fertility is the increase in the K, S and B availability, fact that it strengthens the important paper of the organic matter mineralization in the nutrients cicling in coffee agroecossystems.
