TRACE ELEMENTS: Very Important In Farming

Lack of calcium in tomato will result in bottom end rot of the fruits. (photo credit,

Plants need micronutrients in very small amounts but they are important nevertheless in the plants’ proper growth, flowering and fruiting. Let’s get to know them.

CALCIUM (Ca) – It is required by plants for continuous cell division and formation. It increases fruit setting; controls water intake/usage of cell colloids. If calcium-deficient, roots become weak and leaves are not normal in appearance with brownish coloring. In tomato, calcium deficiency often results in blossom end rot of fruit.

MAGNESIUM (Mg) – Important nutrient in the production of chlorophyll and in the process of photosynthesis. Supports optimum uptake/usage of phosphorus in the plant. Activates important enzymes in plants that help in the good/healthy coloration of plants. If magnesium-deficient, leaves become yellowish and easily fall from the stems.

SULFUR (S) – Plays a vital part in the protoplasm structure, odor and color of the plant.  It is required in chlorophyll production. Activates special enzymes in plants. It is important part of amino acids, cystine, cysteine and methionine.  If sulfur-deficient, growth is affected and leaves become short and round, hard and brittle. Leaves easily fall from the tree and growing buds easily die.

IRON (Fe) – Important nutrient in the production of chlorophyll and in the process of photosynthesis. Helps in the mechanism of enzymes for respiration and transfer of oxygen in the plant cells. Part of the process and reaction of plants related to cell division and growth. If iron-deficient, the leaves become yellowish.

MANGANESE (Mn) – Acts as channel to make important enzymes in plants. Activates enzymes in plants needed in the oxidation, reduction and hydrolysis process. It is part of the photosynthesis process  If deficient in manganese, leaves become yellowish with white spots

When papaya does not receive enough boron, the fruits are lumpy and very ugly. (photo credit:
With the right amount of boron, the fruits are well-formed with smooth skin.
With enough boron, the fruits are sweeter and juicier.

BORON (B) – Helps in the transport of carbohydrates in plants. Increases flowering. Helps in the transport of sugar, aids in plant reproduction, supports the uptake of water in plants. Gives good fruit quality and longer fruit shelf life. If boron-deficient, stems and branches become brittle and there is abnormality in the fruit formation/shape/appearance. Fruits of boron-deficient papaya, for instance, have unsightly lumps (bukol-bukol).

ZINC (Zn) – Supports healthy growth and size of plants in general. A requirement in the protein making process in plants. Supports good seed and grain formation and fruit ripening. If zinc-deficient, there is a decrease in fruit and grain quantity and leaves become yellowish.

COPPER (Cu) – Important part of the photosynthesis process and in the reproductive stages in plants. Aids in the proper respiration of plants and helps increase the level  of sugar and healthy color of plants.  Improves the  taste/flavor of fruits/vegetables. If copper-deficient, leaves become bluish and young leaves do not mature and easily die.

CHLORINE (Cl) – Required in the photosynthesis (food-making) process in plants. If not sufficient, roots become fat and short and plants easily wilt. (WARNING: Chlorine can be harmful to plants if its level in the soil is over 5%).

  1. Thank you very much sa walang sawa ninyong pagpapadala ng magagandang information tungkol sa agrikultura thru my e-mail. Dalawang taon na po akong bumibili ng magazine Agriculture. Isa rin po ako sa mga tagasugid na tagahanga ng inyong programang Agribiz Kapihan sa Taytay. Medyo nalungkot lang ako dahil wala ng schedule
    sa taong ito. Ipinagpatuloy ko na lang sa pag-attend sa Edible Garden Club ng kaibigan ninyong si Sir Toto ng Harbest. ilan beses ko na kayong na-meet ng personal. Isa po akong retired OFW, pero sa aking edad na 72 ay hindi ako nagatubiling mag-aral at umateend ng mga seminar. Dahil sa mga announcement ninyo, pinupuntahan ko po ang mga seminar at exibitions, Nag=papractice po ako ng urban gardening, mayroon po akong roof garden at lahat po ng aking mga tanim ay nasa paso.
    God bless po sa inyo at maraming salamat ulit !
