Organic Gardening: Practices, Manure & Benefits
Learn about organic gardening, natural manure, pest control methods, green manure preparation, and sustainable farming practices.
Introduction
Organic gardening is a sustainable method of crop production that focuses on the use of natural materials and environmentally friendly practices. It avoids the use of synthetic chemicals such as artificial fertilizers and pesticides.
This method of farming promotes:
- Healthy crops
- Safe food for consumption
- Protection of the environment
Organic gardening relies on natural processes such as decomposition, recycling of waste, and biological pest control to maintain soil fertility and crop health.
What Is Organic Manure?
Organic manure refers to natural materials used to improve soil fertility. These materials come from plant and animal sources and are allowed to decompose before being added to the soil.
Examples of Organic Manure
- Animal waste (dung, urine)
- Crop residues
- Plant materials
These materials are broken down naturally and added to the soil to:
- Enrich nutrients
- Improve soil condition
Key Points on Organic Manure
- Made from plant and animal waste
- Environmentally friendly
- Improves soil fertility
- Improves soil structure
- Improves water retention
Organic manure is important because it restores soil nutrients without harming the environment.
Organic Gardening Practices
Organic gardening involves several practices that work together to ensure healthy crop production without the use of chemicals.
Organic gardening practices include:
1. Use of Organic Manure
Organic manure is applied to the soil to improve fertility and support plant growth.
- Supplies essential nutrients
- Improves soil texture
- Enhances water retention
2. Use of Organic Pesticides
Organic pesticides are natural substances used to control pests without harming humans, animals, or beneficial insects.
Examples:
- Neem oil
- Extracted from neem seeds
- Controls pests like aphids, mites, caterpillars, and white flies.
- It is directly applied to crops
- Pyrethrum extract
- Made from pyrethrum flowers
- Mixed with water and sprayed
- Garlic solution
- Crushed garlic mixed with water
- Repels pests
- Onion solution
- Chopped onions mixed with water
- Controls pests by causing respiratoy failure
- Ash
- Applied directly to crops
- Acts as a natural pesticide
- Soapy water
- Soap mixed with water
- Prevents insect damage
3. Mechanical Weed Control
Mechanical weed control involves removing weeds using physical methods instead of chemicals.
Methods:
- Uprooting
- Removing weeds from the roots manually
- Tilling
- Using tools like a jembe to remove weeds and loosen soil
- Slashing
- Cutting weeds using a panga or a slasher
- Mulching
- Covering soil to suppress weed growth by denying them sunlight
Key Considerations:
- Avoid damaging crops
- Weed regularly
- Reduce competition for nutrients, water, and sunlight
4. Use of Organic Foliar Feed
Organic foliar feed is a liquid fertilizer applied directly to plant leaves to supply nutrients quickly.
Importance:
- Provides nutrients faster than soil application
- Improves plant growth
- Increases crop yield
Preparing Organic Foliar Feed
Materials Needed:
- Leaves (e.g., Mexican sunflower)
- Water
- Bucket
- Crushed eggshells
- Knife
- Sieve
Procedure:
- Cut leaves into small pieces
- Place them in a bucket
- Add crushed eggshells
- Add water and cover
- Leave for about two weeks to ferment
- Sieve the mixture
- Spray on crops
