Sodium Contents in Dairy Cow Urine and Soil Aggregate Sizes Influence the Amount of Nitrogen Lost from Soil

Figure 1

Changes in water-filled pore space (WFPS %) during the experiment. Triangles, squares, and circles are small, medium, and large aggregates, respectively. The errors were standard deviations (). The arrows express the timings for urine application and three simulated heavy rains.
