Soil TypesParticle size
Soil Profile
Nutrients
• Nitrogen- Chlorophyll, proteins, nucleic acids• Phosphorus- nucleic acids, ATP• Potassium- Maintaining osmotic potential,
found in enzymes• Chlorine- Root and shoot growth,
photosynthesis• Sulfur- Component of most proteins
Soil PH
Lowering Soil PH
Sulfur Acid Fertilizer—Containing
Sulfur Do not use urea based
fertilizer
Salinity
Reducing Salinity•Water and plenty of it• Increase Organic Matter•Deep Tillage
Organic Amendments
•Peat Moss•Compost•Manure• Straw•Wood Products
Benefits of Organics• Increase Nutrient Holding
Capacity• Increase Water Holding Capacity• Increase Soil Perculation• Increase Aeration• Reduced Erosion
How Much Organics• 100 square feet• 12 inch depth• Desire 10% organic matter• 100 x 1 = 100 cubic feet x 10% = 10
cubic feet• 10 cubic feet / 27 cuft/yd = .3 cu yd• 10 cuft/ 2 cuft = 5 bags
Inorganic Amendments•Perlite•Vermiculite• Scoria• Sand•Glass
Benefits of Inorganics• Increase Aeration• Increase Water Holding
Capacity• Improve Root Growth• Lighten Container Mixes
