I'm still struggling with soil recipes.
I know there are proven mixes, but I keep returning to ideas about what is natural.
A large amount of peat moss or other "soil-less" soil just doesn't seem right.
I have no problem with crab shell (or the New a England version; lobster shell.)
It seems natural for a plant to grow in a shell mound/midden.
I have no problem with neem. It is the lucky seed that germinates beside a fallen neem branch.
A high quantity of peat moss doesn't seem right. Do plants grow naturally in high peat moss soil?
There's not much nutrient value in the peat bogs to support plant life. The plants that grow naturally in peat bogs include the gloriously beautiful sundews - one of my favorite carnivorous plants. I keep meaning to get a couple to catch fungus gnats.
Forgive the teacher who reared her head at this post.
It's not natural to raise cannabis indoors. To do so successfully we must make accommodations to offer the plant the greatest chance of success. Sphagnum peat moss is an integral part of those accommodations for all of the reasons listed below and garnered from the link I attached.
Characteristics and Qualities of Sphagnum Peat Moss
Sphagnum peat moss has many uses in horticulture because of its excellent physical and chemical properties. It can be used as a seed-starting medium, mixed into potting mixes added to compost, and incorporated into the soil as a beneficial amendment that binds sandy soil, loosens clay soil, and reduces leaching of nutrients. Peat moss is a natural, organic soil conditioner, with a unique structure that provides a good balance of air and water around plant roots for healthy plant growth.
Important Properties of Sphagnum Peat
pH
pH is a measure of the soil's acidity or alkalinity. Peat has a pH of 3.5-4.5, described on the pH scale as very acid. It can be used as a soil amendment to lower the pH of the soil, and is especially good when growing acid-Ioving plants such as azaleas, rhododendrons, and blueberries. The pH of soil mixes containing peat can be easily adjusted using lime for plants that require a pH that is closer to neutral (7.0).
Organic Matter
Organic matter is an important part of healthy soil. Peat contains more than 95% organic matter (and less than 2% ash) making it a beneficial amendment that improves soil structure and the activity of soil microorganisms.
Cation Exchange Capacity
The cation exchange capacity (C.E.C.) indicates a soil's ability to adsorb and hold nutrients until they are needed by plants. Sphagnum peat has an excellent cation exchange capacity value of 110 to 130. Sandy soils have a C.E.C. of 2 to 4, while clay soils have a C.E.C. of 4 to 60, indicating a poor ability to adsorb and hold nutrients.
Pore Volume
Pore volume indicates a soil's ability to hold water and air. Sphagnum peat has a pore volume of more than 96%, which makes it an excellent material for potting mixes and soil improvement. Fine sand has about 45% total porosity, while a clay loam has about 60%.
Nitrogen Content
Peat contains 0.5% to 2.5% total nitrogen. However, the nitrogen held in peat is not quickly released so it is not always available for plants to use. Additional nitrogen fertilizer may be needed for healthy plant growth.
Practical Benefits of Using Sphagnum Peat Moss
Adds organic matter. Sphagnum peat is high in organic matter, which can be used to
improve the structure of soil
Holds moisture. Sphagnum peat can hold up to 20 times its dry weight in moisture. The water is released slowly to plants as needed, resulting in less frequent watering needed.
Aerates heavy soils. Sphagnum peat helps loosen and aerate clay soils to allow for proper root growth and development.
Binds sandy soils. Sphagnum peat adds body to light, sandy soil to help it retain water and nutrients.
Holds fertilizer and prevents leaching. Sphagnum peat stores nutrients and reduces leaching of nutrients that are easily lost.
Protects soil. Sphagnum peat protects the soil from hardening and reduces the potential for erosion due to wind and heavy rain.
Decomposes slowly. Sphagnum peat decomposes slowly over several years compared to other types of organic matter such as compost, that decompose within one year.
Sustainable resource. Sphagnum peat is a living resource that accumulates in the natural environment by as much as 1⁄8 inch to 1⁄4 inch every year under favorable conditions. Responsible peatland management and harvesting is key to maintaining an inexhaustible source of peat
Just a little food for thought on this snowy winter day Rad.
And I love stopping by your grow. The comradery you have with SoilGirl and CoOrganics really works.
You bring out the best statements from them, just as you bring out the best performance from cfl bulbs.
What a lovely compliment Rad. It brought a big smile to my face.
