What is good soil drainage?
Basically it means water moves through the soil in a timely manner that’s optimal for growth of most plants.
Figuring out if you have well-drained soil is relatively easy.
What you need:
Trowel or hoe
Watering can or hose
Stopwatch or Watch
Follow the simple instructions below:
- Dig a hole 30 cm deep and 30 cm wide (1 foot by 1 foot)
- Fill the hole with water (use a watering can or garden hose)
- Watch to see how long it takes to drain
What does the time for drainage mean?
- 0-15 minutes: Too slow. Your soil is sandy; it will not hold water or nutrients
- 30 – 60 minutes: Drains just right. It drains well. It’s could be a soil that has enough structure (clay), enough organic matter (sandy) or it’s the uncompacted ideal soil type, loam.
- More than 24 hours: Too slow. Your topsoil is probably compacted (clay) or you might have a clay subsoil..
