Y " Z, One of the experiment fields is located on the Experiment _
i   V- Station farm at Lexington, which is typical Trenton Area soil ’
E V _ Ei II containing 10,000 pounds of phosphorus per acre. It is neu- `
i     tral; that is, it is not acid, 11or does it contain carbonate of
    il]  lime. Below are given some of the yields from this field which
  ·   l has been under experiment since 1911. In the average yields
  v’»- I VVVV   ·l· are included seven corn crops, six soy bean seed crops, five _
