🌱European states' fascination with black powder led to the collection of nitrates, including potassium nitrate, which also serves as fertilizer for gardens.
⚔️Prior to the introduction of gunpowder, European armies relied on pikes and crossbows in battle.
🏰Churches were a common location for collecting urine-soaked earth, a source of nitrates, during earlier times.
🚜Modern urine collection methods use bottles carried by truck drivers, providing a convenient source of nitrogen for garden fertilization.
💡After 10 months of percolation, urine and compostable material transform into potassium nitrate, sodium nitrate, and ammonium nitrate, all beneficial for plant growth.
