Phosphorus and Minor Element Content of Vegetables

The P, B, Mn, Fe, Mo, Cu, and Co content of the same samples of snapbeans and tomatoes from all 10 states are shown in Table 4. Studies of these state average values, in conjunction with the 204 individual values, of which only the extremes are shown at the bottom of the table, permit of the following conclusions:

  1. P values are relatively constant from state to state, but the individual values for each vegetable vary between wide extremes.
  2. B, Fe, Mo, Cu, and Co values tend to increase from east to west.
  3. Mn values tend to decrease from east to west.
