Education program on nutrition. Scholars confirm that there were only 16 elements from elements found in this world is about more than hundred elements. But that are essential to the growth of crops and livelihoods.

Essential elements for plants from the air and water are three elements carbon, oxygen and hydrogen. Carbon and oxygen. Plants from the air as carbon dioxide (CO 2) of hydrogen.

Plants from water (H2O).

For the other 13 essential nutrients from the soil elements divided into 3 groups of nutrients is large.

1. Macronutrients. Contain nitrogen (N), phosphorus (P) potassium (K).

2. Nutrient secondary Consists of calcium (Ca), magnesium (Mg) and sulfur (S).

3. Micronutrient supplements or nutrients. Contains iron (Fe), manganese (Mn), zinc (Zn), copper (Cu) B (Br) molybdenum (Mo) and chlorine (Cl).

When plants are not enough nutrients each. It will show deficiency symptoms that appear to come out the style and location of symptoms, when nutrient deficiency is based on the movement of nutrients from the plant as follows.

1. The elements that move within the plant (mobile element) such as nitrogen, phosphorus, potassium, magnesium and molybdenum. When plants lack these elements will show deficiency symptoms on leaves below. Or leaves before the rest because these elements can move from leaf to leaf to the ground or leaves created a new one. Deficiency symptoms are prominent such.

1.1  Lack of nitrogen. The pale yellow leaves. Leaf tip and leaf margin and spread into the dried stems lanky branches are few.

1.2  The lack of phosphorus. The leaves are yellow, purple-flowering, late flowering and small fruit at the very root.

1.3  potassium deficiency. Quality and yield decreased as much bad taste, color, size, and the disease easily.

1.4  magnesium deficiency. The lower leaves yellow. But the green line and the low yield.

2. The moving elements are not (immobile element) such as calcium, iron, manganese, sulfur, copper, zinc and boron deficiency on these plants show deficiency symptoms on the leaves or the leaves of the plant before the other

Deficiency symptoms are prominent such.

2.1  Lack of calcium The root tip and leaves a short stub roll bending distortion.

2.2 The lack of iron. The pale yellow leaves and dying from the top down.

2.3 zinc deficiency. Will cause a small amount of pale orange, a leaf of glass to determine that plants lack any element that May be determined by the symptoms expressed plants. If the symptoms do not definitely have to use. Compared with the experimental crops to malnutrition. Each is compared. Finally, the analysis of soil and plants that are the problem.
