At present, the increase in production capacity of land for agricultural production important day, the economic sustainability of the activity are aimed. Strategies such as the adoption of the Crop Animal Integration System (ILP) have been developed to increase the maximum area use and productivity of the land, which remain fallow during winter. The success of this technological solution depends on several factors intertwined in production, both plant and animal. In this sense, it is intended to increase nutrient utilization efficiency, such as nitrogen (N), an element strongly required by plants. However, the optimal nitrogen fertilization should be adjusted to meet the need of the cultivation system in plant productivity, but with minimal risk to the environment. On the ground, the N is subjected to a large number of reactions, so it is difficult to be treated efficiently. Although their losses from an agricultural point of view are small, the environmental aspect they are important because, depending on soil properties, this element contaminates the ground water can be washed out. Research on the ILP system is becoming more closely related and has become news in agriculture senary to open a new set of management options for farmers. Accordingly, the aim was to evaluate the relationship between the nitrogen fertilization times and grass heights in the system on the behavior of mineral nitrogen in the soil in an ILP system.The experiment was conducted in the city of Abelardo Luz - SC. The experimental setup was a randomized block with three repetitions distributed factorial (2x2x4). The first factor was fertilization time N: N applied to the pasture (Meadow N fertilization) and N applied to the grain harvest (N-Fertilization Grain) at a dose of 200 kg N ha-1. The second factor was grass height marked by two heights of pasture management (high and low height). The third factor is N doses (0,50, 10 and 150 kg N ha-1) applied to cover the beans in isolated area section. The system's fertilizer practice, namely, applied to grassland before the concentrated culture grains have greater N-NO3- content in the soil. |
