The third crop - broccoli
After the next crop is planted, the nitrate drops quite sharply. The blue line now represents the third crop in the sequence – broccoli. Some of the decrease in nitrate is due to crop uptake. However the initial decline is a bit too sudden to be explained by uptake alone. I had to irrigate to get the new crop started and rain following irrigation inevitably leads to some leaching.
