Theoretical and experimental data on the travel and deposition of small particles in the atmosphere are used to calculate the cross‐pollination between neighbouring plots of sugar beet grown for seed. If two 20 acre plots are situated at a distance apart of 1,000 m the number of pollen grains falling on one plot which come from the other is about 4 × 10 −3 of the number which come from the plot itself. The effect of varying the size and separation of the plots is calculated, and a very approximate estimate of the contribution from background sources of pollen is given. The calculations are made for average meteorological conditions. In moderately unstable conditions the proportion of cross‐pollination between plots is likely to be reduced by about 25 per cent.
