Organic Fertiliser


Understanding Organic Fertilizers

Organic fertilizers are like a gourmet meal for your plants, sourced from natural materials such as plants, animals, and minerals. Unlike their synthetic counterparts, these fertilizers release nutrients gradually, ensuring a sustained and balanced supply. They do more than just feed your plants – they improve soil quality, boost microbial activity, and contribute to a healthier ecosystem in your garden.

Benefits of Organic Fertilizers

Balanced Nutrition: Organic fertilizers deliver a holistic mix of nutrients essential for robust plant growth, with nitrogen, phosphorus, and potassium in the spotlight. The gradual nutrient release prevents imbalances that can harm your plants.

Soil Enrichment: These fertilizers work like soil superheroes, enriching its structure and fertility. They encourage the development of humus, which improves water retention, aeration, and drainage.

Microbial Harmony: Organic fertilizers foster the growth of beneficial microorganisms and earthworms. These microscopic allies break down organic matter, releasing nutrients in a form plants can absorb.

Eco-Friendly Choice: Opting for organic fertilizers demonstrates environmental responsibility. They lower the risk of water pollution from nutrient runoff and minimize the ecological footprint linked to synthetic fertilizers.

Long-Term Payoff: While synthetic fertilizers offer quick fixes, organic options nurture plants over time. This leads to healthier growth and better resilience, aligning with sustainable gardening practices.

Homemade Organic Fertilizer Recipes

Compost Tea:

  • Ingredients: A bucket, water, compost.
  • Method: Fill the bucket with water, add a shovel of compost, and stir occasionally for a few days. Dilute the mixture until it resembles weak tea and use it to water your plants.

Banana Peel Fertilizer:

  • Ingredients: Banana peels, water.
  • Method: Chop banana peels, soak them in water for a week, strain the liquid, and dilute it with water. Use it to water plants or as a foliar spray.

Eggshell Fertilizer:

  • Ingredients: Crushed eggshells.
  • Method: Collect and crush eggshells, then sprinkle them around plants. The added calcium benefits plant cell structure.

Fish Emulsion:

  • Ingredients: Fish scraps, water.
  • Method: Blend fish scraps with water to create a slurry, ferment for a few weeks, strain, dilute, and use it as a liquid fertilizer.

Coffee Grounds Fertilizer:

  • Ingredients: Used coffee grounds.
  • Method: Spread coffee grounds around plants to enhance soil organic matter and repel specific pests.

The Wonder of Worm Tea:

Worm tea, also known as vermicompost tea, is a secret weapon for gardeners. This nutrient-rich liquid is produced by steeping worm castings (the waste produced by earthworms) in water. The resulting liquid is teeming with beneficial microorganisms and nutrients that can be absorbed directly by plants’ roots or used as a foliar spray. Worm tea boosts plant growth, improves soil structure, and enhances disease resistance, making it a valuable addition to your gardening toolkit.

Animal Manure as Organic Fertilizer: A Natural Boost for Your Garden

Animal manure serves as a valuable and time-tested organic fertilizer that enriches soil and stimulates plant growth. Different farm animals produce distinct types of manure, each with its unique benefits and considerations:

Chicken Manure:

  • Rich in nitrogen, suitable for leafy plants like lettuce and spinach.
  • Quick nutrient release may require proper composting to avoid burning plants.
  • Provides a boost for rapid growth and vibrant green foliage.

Cow Manure:

  • Well-balanced nutrient profile, suitable for a wide range of crops.
  • Improves soil structure, water retention, and drainage.
  • Enhances overall soil fertility with steady nutrient release.

Horse Manure:

  • High in organic matter and fiber, valuable for soil structure improvement.
  • Requires proper composting due to the presence of weed seeds.
  • Adds nutrients to the soil while promoting aeration.

Pig Manure:

  • Rich in nutrients but must be composted carefully to reduce odors and pathogens.
  • Can be blended with other organic materials for balanced fertilization.
  • Provides a potent nutrient source for plants when properly managed.

Advantages of Using Animal Manure:

  • Natural nutrient source that supports healthy plant growth.
  • Enhances soil structure and water-holding capacity.
  • Contributes to sustainable farming by recycling waste into valuable resources.

Considerations and Potential Drawbacks:

  • Odor can be an issue, especially if not composted properly.
  • Risk of introducing weed seeds and pathogens without thorough composting.
  • Nutrient levels must be balanced to prevent overloading the soil.

When utilizing animal manure as a fertilizer, it’s crucial to manage its application carefully. Composting is often recommended to reduce risks associated with odor, weed seeds, and pathogens. By understanding the specific benefits and drawbacks of different types of animal manure, you can harness their natural power to nurture your garden while promoting a healthier and more productive growing environment.

Using Wood Ash as Organic Fertilizer: Pros and Cons


  • Rich in Nutrients: Wood ash contains essential nutrients such as potassium, calcium, and magnesium, which can enrich the soil and benefit plant growth.
  • Raises pH: Wood ash is alkaline and can help neutralize acidic soils, creating a more suitable environment for a variety of plants.
  • Deters Pests: The alkaline nature of wood ash can deter certain pests and insects, providing natural pest control.
  • Enhances Composting: Adding wood ash to your compost pile can help balance pH levels and encourage the breakdown of organic matter.


  • Over-Acidification Risk: While wood ash can raise pH levels, excessive use can lead to over-acidification of the soil, affecting nutrient availability and plant health.
  • Salt Buildup: Wood ash contains salts, and excessive application can lead to salt buildup in the soil, which can harm plants and inhibit water absorption.
  • Specific Application Needed: Wood ash is best used on soils that are already pH balanced or slightly acidic; it’s not suitable for alkaline soils.
  • Nutrient Imbalance: Overuse of wood ash can disrupt the nutrient balance in the soil, leading to deficiencies of other essential elements.

Conclusion: Using wood ash as an organic fertilizer has its benefits, particularly in terms of nutrient enrichment and pH adjustment. However, caution is necessary to prevent over-application, which can lead to soil imbalances and hinder plant growth. As with any organic material, moderation and understanding the specific needs of your garden are key to using wood ash effectively.


Organic fertilizers provide a natural and eco-friendly approach to nourishing your garden. By exploring homemade recipes and harnessing the power of worm tea, you can nurture your plants while supporting a healthier environment. As you embark on your gardening journey, remember that these organic solutions not only foster plant growth but also contribute to a harmonious and thriving ecosystem right in your backyard. Happy gardening!
