A method for observing the soil Nitrogen cycle in action

Background I had been developing a coir based organic plant growth medium for a couple of years and was getting fairly good results. However I wanted to know exactly what the actual nutrient levels in the mix were so I had a sample tested by a professional soil testing lab. The test was fairly expensive […]

Mesuring Changes in Soil Nitrogen

This post describes the method I have been using to follow changes in soil nitrogen using only simple equipment and inexpensive test strips. It evolved from earlier experiments involving an attempt to stimulate nitrification in an organic plant growth medium. See the post “A method for observing the soil Nitrogen cycle in action” for more […]
