RESUMO:

Limestone is the most used concealer in soil correction, however, its efficiency is limited to the depth of incorporation, an alternative is the use of Lithothamnium, which presents itself as a concealer with greater reaction capacity in the soil. Thus, the objective of the study was to evaluate the structural, morphogenic and productive characteristics of mombaça grass (Megathyrsus maximum jaqc.) Submitted to Lithothamnium doses. The experiment was carried out in a greenhouse of the Federal University of South and Southeast Pará - Unifesspa, in Marabá-PA, from August 2019 to February 2020, using a completely randomized design, in a 4 x 2 factorial scheme. , consisting of four levels of base saturation (36, 45, 60 and 75%), corresponding to doses of 0; 0.81; 2.17 and 3.53 t ha-1 of dolomitic limestone and 0; 0.82; 2.20 and 3.57 t ha-1 of Lithothamnium, respectively, determined by the base saturation method, and two soil acidity correction sources (dolomitic limestone and Lithothamnium), with four replications. Every seven days Mombasa structural characteristics were evaluated and when the average plant height of the treatments reached 0.90 m the cuts and morphogenic and productive analyzes were performed.
