‘Phosphate-Free’ on the 11th day til Earth Day
Fertilizers & Plant Food, Green Living, Lawn Care 1 Comment »On the 11th day til Earth Day my children said to me,
“Our home & garden should be phosphate-free.”
What is phosphorus and why are so many counties and states throughout the US regulating its availability in household and lawn/garden products?
Phosphates are found in most fertilizers (the “P” in the N-P-K plant food nutrient ratio), especially formulated for lawns, and are present in consumer products such as detergent, baking powder, toothpaste, cured meats, pharmaceuticals, and water softeners. Within the past decade research is concluding that an excess in phosphorus is very damaging to our water and marine life.
The Environmental Protection Agency (EPA) has identified eutrophication (over-enrichment with nutrients) as the main threat to water quality. In most cases the nutrient of importance is phosphorus.
With the inclusion of phosphorous in our waterways, the decrease in oxygen severely inhibits the growth of many aquatic organisms, especially fish (e.g., recreational catch fish such as trout) and in extreme cases may lead to massive fish kills. Excessive input of phosphorus can change clear, oxygen-rich, healthy water into cloudy, oxygen-poor, foul smelling, toxic water. Therefore, control of the amount of phosphates entering surface waters from domestic and industrial waste discharges, natural runoff, and erosion is recommended to prevent eutrophication.
The Maine Extension Office reports that 90% of lawns tested in the past five years would not have been any greener with the addition of phosphorous. This means that our lawns and lawn care budgets can stay healthy without using phosphorous. When looking for a do-it-yourself or commercial lawn care program be sure to find one with 0% phosphorus, such as The Happy Gardener’s Lawn Feed n’ Weed and Lawn Conditioner.
Check the ingredient list when choosing garden & lawn fertilizers. Products that include animal manure will also contain high levels of phosphorous. Oklahoma State University Division of Agriculture Sciences & Natural Resources reports that one of the major concerns associated with manure application is the buildup of phosphorous in the soil. This occurs because manure contains more phosphorous than the crops/vegetation require. Choose products that do not contain manures such as The Happy Gardener’s full line of organic, vegetarian plant foods, pest control, weed control and lawn care.
