Understanding Your Report

Your report graphing tile (shown to the right) highlights each of your soils nutrient levels in relationship to their optimal range. The optimal range is determined based on your sample type; (lawn & turf, vegetable garden, ornamental & trees)

Nutrient Roles In Plant Health

Nitrogen (N)

An adequate supply of nitrogen is associated with vigorous vegetative growth and a plant's dark green color.
Nitrates (N-NO3)
Nitrogen in the form of Nitrates is a readily available form of nitrogen not held on soil exchange sites and is prone to leaching if overused.
Ammonium (N-NH4)
Nitrogen in the form of ammonium acts as a source of nitrogen and has an acidifying effect on most soils.
Nitrogen Deficiency
New leaves are light green. Old-growth turn yellow and wilt.

Phosphorus (P-P205)

Plays a vital role in plant reproduction (i.e. fruit production), as well as early root growth and development.
Phosphorus Deficiency
New leaves are darker in color or loss of leaves.

Potassium (K)

Plays a key role in a vast array of physiological processes vital to plant growth, from protein synthesis to maintenance of plant water balance.
Potassium Deficiency
Yellowing at the tips and edges.

Calcium (Ca)

An integral part of plant cell walls. Proper soil pH rarely allows for deficiencies in most agronomic crops.
Calcium Deficiency
Stunted growth and misshapen leaves.

Boron (B)

Roles in sugar transport and cell wall properties.

Manganese (Mn)

Roles in energy transfer and photosynthesis.

Sulfur (S)

Is a common component of plant proteins and vitamins. Elemental sulfur can lower soil pH in most soils.

Iron (Fe)

An essential role in chlorophyll production & photosynthesis.

Magnesium (Mg)

A key component of the chlorophyll molecule plays a critical role in photosynthesis.
Magnesium Deficiency
Veins remain dark while the edges turn yellow.

Zinc (Zn)

Important in cell division & reproduction of genetic DNA.

Copper (Cu)

Roles in photosynthesis and disease resistance

Sodium (Na)

Used in small quantities to aid in metabolism, synthesis of chlorophyll, and water movement. Excess levels can be detrimental.

Fertilizer Recommendations

For Growing Scenario

Your fertilizer recommendation tile (shown to the left) highlights optimal products and rates to correct your nutrient deficiencies (*detailed overview of each section is listed below)

Lawn & Turf

MySoil recommended fertilizers and rates should be applied every 4-6 weeks during the growing season. Use growth patterns, mowing frequency and color observations to guide your next application timing.  Mowing should be performed 2-3 times/week for healthy turf during the growing season. Only mowing 0-1 times/week during the growing season may indicate less than optimal health/growth.      

Vegetable Garden

MySoil product recommendations and rates should cure nutrient deficiencies and provide optimal nutrient levels for the entire growing season for most annual crops.  If sampling “In-Season”, MySoil’s recommendations should help cure most existing deficiencies if they are not too extreme and plants are not too far along. Products and rates are recommended to maximize plant health, yield, flavor, and nutrient density.

Ornamental Garden

Nutrients should be applied every 5-7 weeks during the growing season for annual plants.  Perennial plants may require applications in Fall and Late Spring as a general guide. MySoil recommendations should provide optimal growth, color, and vigor without over or under applying.   

Trees, Shrubs & Vines

Most trees, shrubs and vines will greatly benefit from both Early Spring and Late Spring/ Early Summer fertility applications. Another application should be applied in late Fall or after the harvest of food bearing plants.

pH & Micronutrients

pH adjustments to your soil can take time. Significant changes in soil pH may require many applications over time depending on your soil type. Some soils have a greater ability to resist/buffer against changes in pH.  It is important to stay diligent and monitor your success with testing each season to guide these pH decisions. Most applications are made in Late Fall and Early Spring.

Types of pH Adjustment Products

Dolomitic Lime

Dolomitic lime contains Magnesium (Mg) along with Calcium (Ca) to increase pH in soils with both low pH and Mg deficiencies.

Common Application Rates & Products

Lawns (30-40 lbs/1000 sq. ft.)     Add product links

Gardens (4-5 lbs/100 sq ft)           Add product links

Calcitic Lime

Calcitic lime only contains Calcium (Ca) and is used to increase pH soils not needing Magnesium (Mg).

Common Application Rates & Products

Lawns (30-40 lbs/1000 sq. ft.)     Add product links

Gardens (4-5 lbs/100 sq ft)          Add product links

Elemental Sulfur

Elemental sulfur is used to lower soil pH.  It can take time in some climates for the elemental sulfur to react with your soil to lower pH, but a program with Late fall and Early Spring applications each season will be beneficial in lower your soil’s pH. 

Common Application Rates & Products

Lawns (3-4 lbs/1000 sq. ft.)          Add product links

Gardens (.4-.6 lbs/ 100 sq ft)       Add product links


Micronutrients are just as important to plants as Macronutrients like Nitrogen (N), Phosphorus (P) and Potassium (K), but are used by the plants in much lower quantities.  In general, it is most important to address Macronutrient deficiencies prior to addressing Micronutrients.  Micronutrients are really the “Finishing Touch” for most plants.

Common Application Rates & Products

Rates can vary based on products, follow specific product label rates.
