Wet April Evening - Interesting Rainfall Facts
It's a very wet April evening here in Dublin; earlier the rain was pouring down. This sudden burst of rainfall is very beneficial for your garden plants - be they ornamental or vegetable. Especially since there has been very little rainfall of late. Here are some interesting facts:- Rainwater comes with a wealth of life giving plant nutrients - that is why plants always look greener after heavy rainfall
- When lightening strikes nitrogen in the atmosphere is combined with hydrogen or oxygen to form ammonium & nitrate, two forms of nitrogen which fall to the ground as rainfall
- This water is then absorbed by plants
- Nitrogen is a key constituent of Chlorophyll which causes plants to appear green
- Sulphur is also present in rainwater
- Sulphur is important in the formation of plant amino acids
- Yearly rainfall can provide as much as 40 lbs of sulphur per acre per year
- Dust is carried thousands of miles in the upper atmosphere - it falls to earth during heavy rain
- Dust carries a number of mineral nutrients for plant growth & is transferred to plants in rainwater
