Why Plants need Nutrients?

To raise plant healthy it needs nutrients from the soil and its surroundings. These nutrients are ready available in land but in Urban gardening the nutrients should be supplied for a seed to grow into a healthy plant. Plant requires Sixteen different type of organic nutrients. 

What is organic nutrient?

The Sixteen essential chemical elements for a healthy grow they are called Organic Nutrients. Plants obtain their organic nutrients from the process of photosynthesis by trapping the solar energy in the green leaves and able to synthesize nutrients from CO2 and H2O.

Nutrients from air & water

Nutrients from soil

Primary nutrients

Secondary nutrients


Carbon (C)

Hydrogen (H)

Oxygen (O)

Nitrogen (N)

Phosphorus (P)

Potassium (K)

Calcium (Ca)

Magnesium (Mg)

Sulfur (S)

Boron (B)

Chlorine (Cl)

Copper (Cu)

Iron (Fe)

Manganese (Mn)

Molybdenum (Mo)

Zinc (Zn)

There are of two types of organic nutrients - non mineral and mineral nutrients.

  • Non mineral nutrients consist of Hydrogen, oxygen and carbon. These compounds are absorbed by the process of photosynthesis.
  • Mineral nutrients are divided into two groups upon the amount of requirement in the plants. They are macro nutrients – required in large quantity and micro nutrients – required in small quantity also called as trace elements.
  • Macro Nutrients are divided into 
  1. Primary- Nitrogen, Phospherous and Pottassium
  2. Secondary- Calcium, Magneium and Sulphur
  • Micro Nutrients are Boron, Manganese, Copper, Chloride, molybdenum, zinc and iron. They are also called as trace elements and required in small quantity.

Apart from water and carbon dioxide, plants need different nutrients, to perform better. Organic nutrient are required in minute quantity, if plants are deficient of any nutrient immediate changes are observed like the leaves colour changes, growth is retarded and remains stunted and axial of the stem and leaf colour changes, etc.  Addition of organic nutrients to the potting medium helps plants to obtain different types of nutrients required for plant growth. Blend of organic matters like plant wastes such as leaves, twigs etc, Cow dung, Neem oil and Pogamia cakes, Vermicompost, Bio-fertilizers make these nutrients in totality.


The various nutrients used in Urban Organic Gardening are-

        1. Plant meal - Complete nutrients for plants: Plant meal is a mixture of different organics concentration and nutrient rich food for plants which provide all the nutrients required for a plant and is complete nutrient profile. Plant Meal Consists of - Seaweed, Panchagavya, Bone meal, Neem powder, Bio-fertilizers and Vermicompost. Plant meal is used as a supplement to the potting media and acts as a plant growth promoter. It also enhances the flowering in plants and yield.
        2. Bone meal - Phosphorus and Calcium rich manure: Bone meal is primarily  used as a source of used as a source of phosphorus, calcium and protein. It is a mixture of finely and coarsely ground animal bones and slaughter-house waste products.It is mainly used for controlling blossom end rot in tomato.It also increases the root growth and nutrient uptake by the roots.Helps in metabolic function and photosynthesis. 
        3. Seaweed extract - Nutrient rich Growth Promoter: Seaweed extract is nutrient rich and growth promoter which is extracted and processed from marine brown algae Ascophyllum nodosum which is natural, organic, non-toxic and extracted from infusion under high pressure, hence bio-active and nutrient substances within it the seaweed is retained. It helps the seeds to geminate and provide balance nutrition.
        4. Bio enzyme  – Flower and Fruit Enhancer: Bio enzyme is an environmental friendly soil supplement that contains growth stimulants made of vegetables and fruit peels. It comprises of potassium humate, amino acids derived from protein fractions and vitamin B complex. It helps in uniform growth of the plants. Make the plant able to withstand stress and drought conditions with increase in immunity and yield of the plant.
        5. Vermicompost - Organic manure: Organic compost that is produced by using earthworms which is rich in all essential nutrients required for healthy plant growth.It contains water solvent nutrients and is an excellent nutrient -rich organic manure and soil conditioner.
        6. Neem powder: Neem powder is a natural manure which is rich in all essential plant nutrients and has an excellent insecticidal property because of which it is widely used as insect repellent and nematicide. It is obtained from crushing the dried seeds and kernels of neem tree. Leaves and bark of neem plants is used to enrich the nutrient content. It contains natural NPK (Nitrogen, Phosphorus, Potassium) and other micro nutrients required for better plant growth.
        7. Panchagavya - Growth-promoter and Immunity booster: Panchagavya – Pancha means – five and gavya – cow byproducts in Sanskrit, is an organic product made from Five byproducts of cow viz., Cow dung, Cow urine, Milk, Curd and Ghee through fermentation process. It possesses all the major nutrients (N, P, K), micro nutrients (Fe, Mn, Zn, Cu, Mo, B) and growth hormones (Indole Acetic acid & Gibberllic acid) required for plant growth. It helps in Growth promoter, Immunity booster, Seed Germination and regular use of Panchagavya will increase the shelf-life of fruits and vegetables
        8. Humic granules - Root growth promoter: Humic granules are concentrated fractions of organic matter that is ideal for organic vegetable garden. It is a natural soil conditioner which has high concentration of trace minerals and organic acids. Humic substances are safe to the environment and all living organisms and acts as soil conditioner. 


  • Organic nutrients feed the soil by supplying nutrients to microbes that help keep a healthy, balanced soil ecosystem. These microbes help fight disease and pest, supply secondary nutrients and micronutrients, and create humus that helps with water and nutrient uptake.

  • Most organic nutrients supply a slow, steady release of nutrients to the plants. The nutrients are supplied continuous for a healthy plant growth.

  • Organic nutrients are more widely available in nature.

  • Organic nutrients can be free-if you make your own compost at home.

  • Fertilizers with chemicals don't supply organic matter or feed the soil's micro-organisms.Chemical Fertilizers are like taking a vitamin pill , while organic nutrients are like eating good food.
