Nutrition Program Analysis

Plants are uniquely able to create their own food through photosynthesis, using the sun’s energy to synthesize glucose from carbon dioxide and water. Plants also extract from the air and soil 16 chemical elements that are essential for nutrition, growth and survival.


16 Chemical Elements are Essential to Nutrition, Growth and Survival.


Non-mineral elements – carbon, hydrogen and oxygen – come from the air and water. Beyond irrigation, growers can do little to influence the availability of the non-mineral elements that nature provides. Mineral elements dissolved in water are taken from the soil.

Mineral elements are grouped as macro- and micronutrients, according to their volume consumed by plants and their necessity for plant life.

Macronutrients are mineral elements that plants need in relatively large quantities and that are essential for life:
  • Primary macronutrients – nitrogen, phosphorus and potassium – are usually the first to be found lacking because plants need the largest amounts of these essential minerals.
  • Secondary macronutrients – calcium, magnesium and sulfur – are generally present in sufficient quantities. Calcium and magnesium are also added heavily by lime, which is commonly applied to soils as a pH-balancer.

Micronutrients are mineral elements consumed in trace amounts that are essential for robust growth and health, but generally not for survival.

Macronutrients are present in plant tissues in quantities from 0.2-0.4 percent of dry weight while micronutrients are measured in parts per million, ranging from 5-200 ppm.
