So Little is So Much in Furrow


These photos are a great example of how so little can do much, particularly in furrow. We performed a pH test on the different layers in the soil pit, which gave neutral and alkaline results, we then performed a ‘fizz’ test on the soil using hydrochloric acid, then noticing that the pH test had turned sharply acidic, due to the aerosol the fizz had produced from over a metre away. This is a perfect way to show how the pH in furrow can be altered using only small volumes per hectare.
