Includes all the living things in the soil
•
Can be much higher in soil mixes
Today we want to do a basic overview of plant
nutrients and components of soil mixes.

•
Fertilize heavily with commercial fertilizer
infrequently to save on labor
•
Heavy Commercial Fertilizer:
–
Prone to leaching, Run-off
–
Burn plants (many are salt based)
It is better to apply smaller amounts of
fertilizer frequently.

Develop Healthy Soil
•
Organic Matter Sources:
•
Increases water and nutrient holding
capacity
•
Increases soil tilth/quality
•
Increases soil organism activity (indicates
healthy soil)
•
Releases nutrients slowly as it breaks down

Some Possible Media Components Include:
•
Organic Components: Coconut Coir, Compost, Sifted
Mulch, Peat Moss, Manures & Bark
•
Inorganic Components: Perlite, Vermiculite, River and
Manufactured Sand
•
Soil – Weed Free including seeds, Pest and Disease
Free adds weight to the media
Try you own blend of local materials to save
money.
Gain insights on the basic components of soil, essential soil-based plant nutrients, Liebig's Law of the Minimum Nutrient Balance, and modern nutrient management practices. Learn the importance of feeding the soil to ensure optimal plant growth and productivity in farming business training programs.

13 Essential Soil Based Plant Nutrients Primary - Macronutrients: Nitrogen (N) Phosphorus (P) Potassium (K) %N %P2O5 %K2O
13 Essential Soil Based Plant Nutrients (cont.) Secondary - Macronutrients: Calcium (Ca) Magnesium (Mg) Sulfur (S)

Liebigs Law of the Minimum Nutrient Balance "The availability of the most abundant nutrient in the soil is only as good as the availability of the least abundant nutrient in the soil."
Do not feed your plant! Feed the soil, and the soil will take care of your plants!
Old School Nutrient Management Fertilize heavily with commercial fertilizer infrequently to save on labor Heavy Commercial Fertilizer: Prone to leaching, Run-off Burn plants (many are salt based) It is better to apply smaller amounts of fertilizer frequently.
New School Nutrient Management Develop Healthy Soil Organic Matter Sources: Increases water and nutrient holding capacity Increases soil tilth/quality Increases soil organism activity (indicates healthy soil) Releases nutrients slowly as it breaks down

Locally Available Ingredients & Home Grown Potting Soils Some Possible Media Components Include: Organic Components: Coconut Coir, Compost, Sifted Mulch, Peat Moss, Manures & Bark Inorganic Components: Perlite, Vermiculite, River and Manufactured Sand Soil Weed Free including seeds, Pest and Disease Free adds weight to the media Try you own blend of local materials to save money.
