A direction field for this equation is shown in the figure below.
On the coordinate plane the horizontal axis is labeled t and the vertical axis is labeled P. There is a slope field in the first quadrant on the graph. The slopes are nearly horizontal at P = 0. As P increases, the slopes go up and right becoming more steep until about P = 50, then go up and right becoming less steep, become horizontal near P = 100, and go down and right becoming more steep until they exit the window near P = 150.
