Week 10: Nitrate

I collected water samples from both 20 and 40 cm detectors this week. The nitrate has gone. I'll never know how much was taken up by the crop and how much was leached in the rain. But I am confident I managed the system as well as I could to give the crop the best chance of getting the deep nitrate out of the soil. It is why I gave the small irrgations and let the topsoil dry out on weeks 6, 7 and 9.
