Soil is the life of your garden. The investment will be worth it.
Raised Bed Soil Recipe –– List of OMRI Approved
50% High-Quality Topsoil
30% High-Quality Homemade or Certified Compost
20% Mix of Organic Materials
- Well-aged, shredded leaves
- Vermicompost (Worm Castings)
- Composted Cow or Poultry Manure – NO Added Synthetic Herbicides-With fresh fruits and vegetables, food safety concerns are most often associated with biological contamination by pathogens in manure-based soil amendments.
- Coconut Coir or Peat Moss
- Wood Chips – for pathways between beds– mimicking the forest floor, where leaves and twigs naturally decompose on top of the soil.
12 inch Layers of Healthy Soil in Raised Beds
Top 1-5 inches Rhizosphere
richest nutrients – The rhizosphere contains many bacteria and other microorganisms that feed on sloughed-off plant cells, termed rhizodeposition, and the proteins and sugars released by roots. Rhizosphere normally refers to the region around the plant’s roots that is rich in proteins, organic acids, minerals, and carbon released by the plant’s roots that create a feast for microorganisms which in turn share their sloughed off bounty with the plant’s roots to be readily absorbed. Anaerobic bacteria refers to negative bacteria. Soils can be temporarily anaerobic– like water logged soils on agricultural land or permanently anaerobic– like the natural wetland soils. Under anaerobic conditions, the amount of oxygen used by soil biological organisms exceeds the amount of oxygen diffused into the soil.
5 Components of Maintaining Healthy Soil Web
- 1- Good drainage & aeration
- 2- Organic Matter – compost macronutrients,
- 3- Minerals – rock dust, clay
- 4- Microbes & Fungae – worm castings
- 5- Micro-nutrients
Mineral-Based Soil Amendments
Remineralize Depleted Soils with Volcanic Ash Trace Minerals – Rock Dust
Calcium, magnesium, potash, chlorine, sodium for use in organic production. Organic fertilizer, such as Azomite, a natural product in Utah mined from an ancient volcanic eruption into a seabed. Wake up microbials in the soil and remineralize depleted soils. Azomite is naturally derived, and OMRI-Listed for use in organic production. AZOMITE stands for A to Z of minerals and trace elements. It contains about 67 different minerals and elements. Country Gardens, 2050 Sharpsburg McCollum Road Newnan GA 30265, 770-251-2673
Pulverized Dolomite Lime Treats Acidity in Georgia Soil
Acidity of Georgia red clay is excellent for blueberries. But veggies grow best in neutral or alkaline soils. Lime, chemically known as calcium carbonate,converts the acid to a more alkaline soil. The Georgia Cooperative Extension Service recommends 5 pounds of lime per 100 square feet at 8 inch depth. Triple the amount of lime for deeper treatment. Pulverized lime, is finely ground and gets into the soil more quickly. Georgia soil, deficient in magnesium, which plants need for good growth, needs pulverized dolomite lime, also known as magnesium calcium carbonate.
Plant-Based Soil Amendments
Coconut Coir – Peat Moss Substitute
Easy expanding garden mulch, retains the moisture in the soil
Endo Mycorrhizae– Beneficial Root Fungus
Helps root base, reduces drought stress, water inputs, transplant shock, nutrient loss. Increases yields, fruiting & flowering, survivability. Promotes rooting, nutrient uptake, self sufficient plants. Easy to use water soluble formula. Endomycorrhizae – for annuals Ectomycorrhizae – for perennials
Animal-Based Soil Amendments
Amend Micronutrients with Worm Castings – Vermicompost
similarly known as worm castings or worm manure, enriches the soil and can be used as a high grade natural, organic fertilizer. Non-Toxic, Non-Hazardous, Will NOT Burn Plants, 100% Organic & Safe For All Types of Plants, Add 10-20% By Volume to Potting Mix or Compost for Best Results, ffective way to repel white flies, aphids and spider mites and any pest that feeds on plant juices. Earthworm castings have over 60 micronutrients and trace minerals, including calcium, magnesium, nitrogen, phosphates and potash. Castings act as a barrier to help plants grow in soil where the pH levels are too high or too low. The humus in the castings extracts toxins and harmful fungi and bacteria from the soil.
The soil, itself, doesn’t really feed the plants. Instead, the soil is the environment that promotes a healthy ecosystem below the surface – that can facilitate (or hinder) the ability for air, water and nutrients to be utilized by plants and their roots at an optimal level.
