Abstract

The present scientific initiation aims to train a scholarship holder at the undergraduate level to perform evaluations of losses of N in the form of volatilized ammonia in grazing experiments. As well as performing total N analyzes. The fellow will conduct field surveys, laboratory analyzes, data analyzes, and discuss the results with the research team. The treatments will be: T1 - without application of nitrogen; treatment; T2 - 90 kg N per hectare; T3: 180 kg of N per hectare and T4: 270 kg of N per hectare. The experiment will be carried out in a completely randomized design, with measures repeated in time, being four treatments with five repetitions.
