General soil care objective
Organic solutions
Promote large blooms and fruits
Bat guano (4-13-1)
Alfalfa meal (great for roses, quick
release).
Pro-Gro (5-3-4)
Bio-Magic 0-0-12
Compost
Condition soil
Stress-X liquid seaweed
Build plant hardiness and resistance to disease,
pests and drought
biostimulant (great for lawns)
Promote root growth in transplants and seedlings
Phosphate rock
Pro-Start
Myco-Magic
Bone meal
Bat guano
Add balance blend of main macro-nutrients (nitrogen, phosphorus, potassium,
calcium, magnesium, and sulfur) plus greensand to provide important
micronutrients
Pro-Gro (5-3-4)
Winterize plants
Pro-Start
Enhance composting process
Crab meal
Alfalfa meal (breaks down carbonaceous
material)
Blood meal
Bind sandy soil
Colloidal rock phosphate
Loosen clay soil
Greensand
Sphagnum peat moss
Soil deficiency
Symptoms in turfgrass
How to correct
Acidity
Soil too acid: phosphorus, calcium, magnesium
Aragonite (sweetens soil without adding
availability reduced.
magnesium)
Soil too alkaline: iron, zinc, manganese and copper
Dolomitic limestone (pelletized or powder)
not available.
Boron
Slow growth, pale green tips, bronze tint
Boron 10%
Boron 14.3%
Calcium
Reddish-brown leaves, may curl and die
Gypsum (for alkaline soils)
Calcium limestone flour
Phosphate rock
Fertrell CaFe 9-1-4
Dolomitic limestone (for acid soils)
Copper
Yellow and stunted leaves, tips die
Copper sulfate
Reduce nitrogen fertilization
Iron
Pale leaves, turning yellow
Iron (chelated 10%)
Fertrell CaFe 9-1-4
Iron sulfate
Reduce phosphorus fertilization
Magnesium
Yellow stripes on leaves, turning red
Epsom salt (for alkaline soils)
Sul-Po-Mag
Dolomitic limestone (for acid soils)
Manganese
Yellow spots on leaves, withered at tips
Manganese sulfate
Molybdenum
Yellow and withered leaves
Dolomitic limestone (for acid soils)
Blood meal (quick release)
Cotton seed meal (advisory:acidifies soil)
Corn gluten meal 10-0-0
Cottonseed meal 6-1-1
Crab meal (slow release)
Feather meal (slow release)
Leather meal (slow release)
Nitrogen
Light green or yellow-green leaves, may start
dying at tips
Phosphorus
Raise pH (reduce acidity)
Bone meal (slow release - good for new
Thin sod, thin curled leaves, dusky blue-green with
plants/transplants)
purple tint in cool weather
Phosphate rock
Bat guano
Potassium
Yellow tips on leaves, may turn brown and die at
tips
Kelp meal (quick release, good for fruit/flower
production)
Sul-Po-Mag
Granite meal
Greensand
Greensand Plus (0-0-17)for faster availability
Wood ashes (caution: too much can raise the
pH level too high)
Sulfate of potash (0-0-52)
Sulfur
Yellow leaves
Phosphate rock
Gypsum
Elemental sulfur
Zinc
Small and yellow leaves
Zinc sulfate
Zinc chelates
Trace
elements/minerals
Microbial activity
Kelp meal (quick release, good for fruit/flower
production)
Greensand
Granite meal
Stress-X liquid seaweed biostimulant
