Is Rain Water Better than Ground Water for Plants
- Rain water, especially rain during thunderstorms, contains more nitrogen than ground water. Nitrogen is the first number in a fertilizer listing – 5-10-5, for example, is 5% nitrogen, 10% phosphorous, and 5% potash (potassium). Nitrogen greens leaves. The first number helps leaves, the middle number boosts flowers, the last number boosts roots. Nitrogen is a macro nutrient that plants need.
- Ground water doesn’t lack nitrogen, but the soil tends to add various organic salts to the water as it percolates through the soil particles. These salts interfere with a plant’s ability to absorb nitrogen. It’s not that ground water lacks nitrogen, it’s that it contains other chemicals which may hinder a plant’s ability to absorb nitrogen.
- Thunderstorm rain contains the most nitrogen because of lightning.
- Other particles in the air from pollution, including nitrogen, descends in the dirt particles attached to rain. These also feed plants!
