- Abstract
Considering that the application of water from coffee processing (WCP), via fertigation, can promote changes in the K content of the soil, in the plant and the production of the dry mass of Brachiaria mutica (Capim Angola), work was carried out to evaluate evaluating the available levels of K in the profile of a Floss Neossol, in the plant, and the production of the dry mass of the Angola grass resulting from the application of different doses of WPC. The plots received five treatments: WPC doses 0, 57, 114, 171, and 228m³ / ha, calculated so that the 114m³ / ha dose raised the K content to 5% in the CTC (T) of the soil. Soil samples were collected at 45 and 90 days after WPC application, at depths of 0 to 20 cm; 20 to 40 cm; 40 to 60 cm and 60 to 80 cm. Samples for leaf analysis and dry mass were also collected in the same period. The use of WPC, at a dose of 114 m³ / ha, increased K in the soil only in the 0-20 cm layer. An increase was also observed in lower layers through higher dosages. There was no difference in the production of biomass and nutrient contents in the plant, through the different treatments.
