- [en] the elements calcium, magnesium, sodium and sulphur (IATE); the mineral nutrients are divided into two groups: macronutrients and micronutrients.
Macronutrients Macronutrients can be broken into two more groups: primary and secondary nutrients.
The primary nutrients are nitrogen (N), phosphorus (P), and potassium (K). These major nutrients usually are lacking from the soil first because plants use large amounts for their growth and survival.
The secondary nutrients are calcium (Ca), magnesium (Mg), and sulfur (S). There are usually enough of these nutrients in the soil so fertilization is not always needed. Also, large amounts of Calcium and Magnesium are added when lime is applied to acidic soils. Sulfur is usually found in sufficient amounts from the slow decomposition of soil organic matter, an important reason for not throwing out grass clippings and leaves (http://www.ncagr.gov/cyber/kidswrld/plant/nutrient.htm); Macronutrients: used in large quantities by the plant
Structural nutrients: C, H, O
Primary nutrients: N, P, K
Secondary nutrients: Ca, Mg, S
Micronutrients: used in small quantities by the plant
