Use natural fertilizer.
Natural fertilizers reduce resource use. They contain nitrogen, phosphorus and potassium, the three essential minerals for plant growth. The concentration of these natural fertilizers rarely exceeds 10% (for example 4-2-2 fertilizer, with 4% nitrogen, 2% phosphorus and 2% potassium). Be wary of so called “natural-based” or “organic-based” fertilizers, as they may contain as little as 15% natural products.
Our recommendations :
-
Natural fertilizers of organic origin come from animal waste (feather meal, bone meal, shrimp meal and dehydrated chicken waste) or plant waste (algae emulsion, corn gluten meal, alfalfa meal). The action of natural fertilizers on the soil is slower but more prolonged. They are also less susceptible to being washed away by precipitation, which protects waterways. Their persistence in the soil means they need only be applied twice a year, making them more economical despite their higher purchase cost.
