Q.Ammonia Smell in My Garden Soil
For some odd reason, the container which holds my soil was somehow contaminated on its own and I need some very simple, inexpensive, and quick home remedies to fix the overwhelming scent of ammonia. It has already killed my small soybean plant in a matter of overnight. Please help!! Sincerely, Jamie

This is often caused by a chemical reaction related to fertilizer and overly moist soil, especially if the soil has organic compounds. Root rot is another reason for the smell, and another side effect off too much moisture. Remove the soil, clean out the container, and repot (if the plant's roots are still healthy) in sterilized soil or a soilless potting mix. Sterile mediums don't have this problem to the same degree because there is nothing to break down and decompose. Also, check the container carefully to ensure that adequate drainage is provided.
