Below is a paper about worms that I used in my classes when I worked at a nursery. I still get many inquiries about why I use them, so here you go. You can find worm casting at many garden centers, other wise have a look on line to find them, they are worth the effort. I found these at the Greenhouse Garden Center in Carson City.
The Benefits of Worms
Worms have the ability to travel through the soil take the
organic and mineral fraction of the soil digest them releasing them back to the
soil as castings which are full of nutrients.
These nutrients are order free, slow released, and stay in the soil even
when watered. The nutrients do not leach
out like a chemical fertilizer; they are stored in the soil profile so the
plant has access to them when needed.
Worms also create an aggregated soil which allows for more
oxygen in the soil. This allows more oxygen in the soil to which allows the
roots to move easier through the soil increasing root structure and helps roots
breathe. Better soil structure also helps soil hold moisture.
Worm Castings
Castings have an amazing nutrient package that when added
to soils carry a diverse population of microbial life. Adding casting will
increase diversity of beneficial organisms in soils, promote soil structure and
aid in disease and pest suppression.
Castings have even more beneficial microbes than composts
that are worm free. Nutrients from worms casting go to solution easily, which
means they are broken down by water so the plant can benefit quickly and
continually. These nutrients go to solution easily making them readily
available to the plant quickly and whenever needed without burning. Applying
casting 3 to 4 times a year will fortify soils for continued use and health in
the garden.
Worm casting naturally have 5 times higher nitrogen, 7 times richer
in phosphorus, 3 times richer in,
magnesium, 11 times richer in potassium and 1.5 times richer in calcium.
Worm Tea
With worm castings demonstrating such tremendous benefits to soil, why
should we take steps to generate worm tea? Worm tea contains billions of
beneficial microbes. These microbes can
be absorbed by the leaf surface directly into the plant. The beneficial microbes have the ability to
outcompete the harmful pathogens trying to hurt the plant. Teas also carry the
soluble nutrients and beneficial growth regulators contained in the solid
matter used to make the tea. Many of these compounds can be absorbed through
the leaf surface, feeding and enriching the plant.
Leaf surfaces, like plant roots, harbor rich microbial populations that
protect the leaf, and thus the plant, from infection and attack by disease.
When the microbes in leaves encounter environmental damage, it can exposes leaf
surface, opening infection points.
We can reintroduce beneficial microbes to the leaf by applying the tea
made from compost and worm composting. Further, teas can be applied as soil
drenches and root washes to reintroduce beneficial microbes to the soil. The
microbes can then continue to provide protection from pathogens to the plant as
well.
I have made it a habit to write down when and what I plant. This card will be in my garden binder. I will be planting more bulbs in a week or two. The weather will determine my next trip to my bulb planters.
