Introduction Trees, like all other living plants, have many nutritional requirements for sustained growth and reproduction. There are various methods of determining the available nutrients in the soil, as well as methods of determining the amount of nutrients absorbed by the tree. When certain nutrients are deficient in the soil, fertilizers may be able to correct the deficiency.
Fertilizers come in many forms and are applied in many ways.
The amount and kind of vegetation in the area, as well as the reasons for fertilization are critical factors in determining the application method to use. Nutrients Trees and other woody ornamentals require large quantities of six macronutrients and lesser quantities of ten micronutrients. The most important of the macronutrients is nitrogen, which is the most limiting nutrient in the soil. Phosphorus and potassium are also needed in large quantities, but are generally available in the soil. The other three macronutrients are also usually present, but need to be added when a deficiency is noticed.
