Yes it would be safe to grow vegetables
No, potassium is not found in the ground as a native metal. It is highly reactive and typically bonded to other elements in compounds like potassium chloride or potassium nitrate.
As potassium nitrate, charcoal, and sulfur are ground together, the increased surface area and intimate mixing of the particles allow for more rapid and efficient chemical reactions to occur. This can lead to the formation of small, high-pressure pockets of gas which, when ignited, can cause a rapid release of energy, resulting in an explosion.
It is a Non Vascular plant which is meant to be short and close to the ground
Sodium nitrate is a type of salt that happens to be a particularly effective food preservative. A naturally occurring mineral, sodium nitrate is present in all kinds of vegetables (root veggies like carrots as well as leafy greens like celery and spinach) along with all sorts of fruits and grains. Basically, anything that grows from the ground draws sodium nitrate out of the soil.
The reactants are all solids at standard temperature and pressure and therefore can initially react with one another only at the surfaces of the particles in which each reagent is present. Grinding greater increases the surface area of each reaction, thereby facility quick reaction of the entire supply of each reagent.
No, they are ground vegetables
Till the soil, plant the see, water it and then keep the weeds pulled.
Common vegetables which grow above ground include: Broccoli, cauliflower, brussels sprouts, asparagus, spinach, lettuce, cabbage, various greens, celery, rhubarb. Squashes (including pumpkins), tomatoes, cucumbers, peppers, eggplant, okra, green beans and peas are technically fruits, but they are used as vegetables. Peanuts are a special case: they are legumes similar to beans and peas, the fruit pods form above ground but they force their way into the ground to mature. Vegetables that grow underground include: Potatoes, carrots, parsnips, beets, radishes, turnips, onions, garlic. Onions do not grow underground an onion bulb is a swollen stem.

Vegetables for which the edible part grows from the ground are asparagus, rhubarb, leaf lettuce, etc.
Turnips are vegetables. These vegetables are grown in the ground in much the same way that a potato goes in the ground.
The chemical formula of gunpowder is typically written as KNO3 + S + C. This reflects the combination of potassium nitrate (saltpeter), sulfur, and carbon that make up the primary components of gunpowder.
