Based on the provided YouTube video reference titled "How to Remove a Tree Stump Painlessly", the method described for softening a tree stump does not involve the use of potassium nitrate.
The video segment provided focuses on a different approach to prepare the stump for removal by making it spongy over time.
Method Described in the Reference
The technique shown in the suggested clip from the video involves using hot water to soften the stump.
- Drilling Holes: It is implied that holes are drilled into the stump (though the drilling step isn't explicitly shown in the clip text, it's a standard precursor to adding substances to a stump).
- Adding Hot Water: Hot water is added to these holes.
- Patience and Repetition: This is described as where "the patience comes in". You continue adding hot water to the holes for a few days afterward.
- Waiting Period: After this treatment, it takes time for the stump to break down. The clip states that in about four to six weeks, the stump is going to get really spongy.
This sponginess makes the stump easier to break apart and remove manually or through other means. The reference does not mention any chemical, including potassium nitrate, being used in this process.
Therefore, while potassium nitrate is a known method for accelerating stump decomposition, the provided reference illustrates a technique using repeated application of hot water and a waiting period to achieve a spongy texture suitable for removal.
