%X Um experimento de campo foi executado, no per¨ªodo de mar o/2005 a fevereiro/2007, no munic¨ªpio de Rem¨ªgio, PB, para avaliar o efeito do biofertilizante supermagro (esterco fresco de bovino + ¨¢gua + macro e micro nutrientes), aplicado ao solo na forma l¨ªquida, sobre os teores de micronutrientes e s¨®dio no solo. O trabalho consistiu na combina  o de dois fatores: doses de supermagro, dilu¨ªdo em ¨¢gua na raz o de 1:4 (0, 1, 2, 3 e 4 L por planta), combinadas ¨¤ aduba  o de K2O (com e sem K2O), oriundo de cloreto de pot¨¢ssio, compondo um fatorial 5 x 2, no delineamento experimental em blocos casualizados, com tr¨ºs repeti  es. A aplica  o de supermagro, independentemente da adi  o de K2O, promoveu aumento dos teores de boro, cobre, mangan¨ºs e zinco, mas n o interferiu nos conte¨²dos de ferro e s¨®dio no solo. A field experiment was carried out during the period from March/2005 to February/2007, in the municipality of Rem¨ªgio, Para¨ªba State, Brazil, in order to evaluate the action of the ¡°supermagro¡± biofertilizer (fresh bovine manure + water + macro and micronutrients) applied on the soil in liquid form, on the contents of soil micronutrients and sodium. The treatments were distributed in randomized blocks, with three repetitions, using the factorial design 5 x 2, consisting of levels of ¡°supermagro¡± biofertilizer diluted in water in a 1:4 proportion (0, 1, 2, 3 and 4 L per plant), combined with K2O fertilization (with and without K2O), obtained from potassium chloride. The biofertilizer application on the soil in treatments without and with K2O, increased the contents of boron, copper, manganese and zinc on the soil, but had no effects on sodium and iron content.
