Water Cycle

These cold and rainy fall days may feel a little uncomfortable, but with the rain, the land is actually getting a “recharge.”  The land is coming out of a drought year. We need the aquifers refilled to maintain drinking water and long term watershed supply. When it rains, water does not stop moving when it hits the ground. Some water flows along the land into streams, bays, and lakes. Some water is used up by trees and plants and other water particles evaporate and return to the atmosphere which increases humidity and storm potential. Local forecasts keep changing for snow and precipitation projections but based on the water systematic increases, water increases the potential recycling within the local system.  It also provides opportunities to balance carbon and other important air quality effects from the local community and ecosystem.

Recharge and water supply from the fall perspective set up the local community to withstand the frost freeze changes during winter months.  Many storms like the last week, while consistent and bountiful, the 5 inches of average rain in the last week has helped elevate water tables, recharge many local wells and increase Lake Ontario’s water level during times of draw down to help balance shoreline levels. All surface water has a purpose and excess water seeps into the ground.

The water that seeps into the ground clings to particles of soil and plant roots just below the land surface that provide plants enough to grow. It also provides winter resiliency for the plants during hardening for healthy stock next year. The water not used by plants moves deeper into the ground and downward through empty spaces or cracks in the soil, sand, or rocks until it reaches a layer of rock through which water cannot easily move. This creates a reserve.   The top of the water in the soil, sand, or rocks is called the water table, and the water that fills the empty spaces and cracks is called the groundwater zone. Water seeping down from the land surface adds to the groundwater and is called recharge water. Maintaining good aquifer levels will support water storage for water treatment systems and irrigation for agricultural production, and the garden plants and trees.

Now is the time of year to be conscious of the yard and garden clean-up. Make sure you keep leaves and grass out of storm drains.  Fallen leaves and grass clippings can plug storm drains and can cause flooding to our roadways.  If yard waste such as leaves, grass clippings, and small twigs are disposed of in a storm drain, they will make their way to a natural body of water where they threaten aquatic life and degrade water quality.

Don’t feel obligated to rake up every last leaf in your yard this fall. Let some leaves stay on the ground — they have many benefits to wildlife and the garden. A leaf layer sometimes called duff, several inches deep is natural on forest floors. This leaf layer is its own mini-ecosystem! Many wildlife species live in or rely on the leaf layer to find food like earthworms and other beneficial microbes.

From a gardening perspective, fallen leaves offer a double benefit. Leaves will form a natural mulch that helps suppress weeds and at the same time fertilize the soil as they break down. Why spend money on mulch and fertilizer when you can make your own? Here is a great video on how to create leaf mold, it takes a few years, but it is considered garden gold. Farmer’s Almanac  page.

If leaves must be racked, don’t throw them in the trash. Compost them or drop them off at a municipal recycling center so they can be turned into compost that you and other members of your community can use in the spring. Some communities even offer curb-side pick up of leaves specifically for municipal composting operations.

1. Leaves make good insulation for overwintering tender perennials. The best time to mulch perennials is after the ground has frozen, so put aside shredded leaves in bags to use later in the fall.
2. Mow leaves and clippings into the lawn, lawns actually benefit from thin layers of leaves. Leaf litter improves the soil, lessening the need for fertilizer in the spring.
3. Leaf humus can lighten heavy clay soils, so leave a layer in the garden.
4. Leaves increase the moisture retention of dry, sandy soils.

Happy Raking!
