ABSTRACT The development and survival of Eucalyptus urograndis plants may be influenced by products based on humic fractions of the organic matter, purified MAP and soil conditioners, such as hydrogel. Thus, the present study aimed to evaluate the effect of the commercial products Fertiactyl®, based on humic substances, purified MAP and hydrogel on the post-planting development and survival of Eucalyptus urograndis. The experiment was conducted in a randomized block design, with 25 treatments and four replicates, each of which consisted of 6 plants. The immersion of the tubes in solution with doses of Fertiactyl® and purified MAP promoted the increase in the development and survival of the plants. In the preparation of the hydrogel, the use of solution based on Fertiactyl® and purified MAP reduced the hydration capacity of the water-retaining polymer. With increasing doses, there was a linear increment in the electrical conductivity of the solution, exponentially reducing the hydration capacity of the polymer.
