Vermont Phosphorus Law
Vermont Law limits the use of phosphorous on existing lawns and stipulates the use of water-insoluble nitrogen in all lawn fertilizers.
Fertilizers containing phosphorus shall not be applied to lawns unless they’re applied to new lawns or soil tests indicate that the lawn has a phosphorus deficiency. This is because phosphorus runoff poses a threat to water quality. Most lawns in the Vermont area don’t benefit from fertilizer containing phosphorus.
At L.D. Oliver Seed Co, we’ve changed our fertilizer formulas to comply with the Vermont statute. No fertilizer is to be applied to lawns before April 1st or after October 15th, or when the ground is frozen. We blend lake-friendly fertilizers at our facility.
Fertilizer Analysis and Application
Fertilizer analysis gives the percentage of the three essential plant foods: nitrogen, phosphorus, and potassium. Additional numbers indicate the amount of secondary or minor plant food elements: magnesium (Mg), copper (Cu), zinc (Zn), iron (Fe), manganese (Mn), boron (B), and sulfur (S).
Nitrogen promotes the growth of leaves and stems, stimulates rapid early growth, and makes the plant greener. Nitrogen deficiency in plants causes stunted growth and yellow leaves.
Phosphorus is essential for root formation and growth. It’s particularly helpful to root crops, such as potatoes, carrots, and beets. Phosphorus deficiency causes the lower leaves to turn red, purple, or an unusual deep green.
Potassium increases plant vigor and resistance to disease. It stimulates the production of strong and stiff stalks; promotes the production of sugar, starch, and oils; and increases the plumpness of fruits and vegetables. Potassium deficiency leads to yellow leaves at the tips and edges, weak stalks, and poor setting of fruits.
