I’m the sort of person that easily forgets certain leftovers and opened jars in the fridge. So of course things start to get a little funky. Instead of throwing things straight in the compost bin I try and take the time to make a natural fertiliser with some of the stinky fridge ingredients.
A natural or biological fertiliser is a liquid which contains living micro-organisms. The role of a bio-fertiliser is to improve micro-organism productivity and thus improve the soil. When applied to plants it aids in the growth and health of the plant and increases the availability of primary nutrients to plants.
Plants basically need 16 mineral elements to function at their optimum. The most important are nitrogen (N), phosphorus (P) and potassium (K). Maybe you know some farmers that add chemical fertilisers (NPK) to their garden. These fertilisers are synthetic, and can cause damage to the soil and the ground water, making them saline. So I like to use natural fertilisers as they are cheap to make, relatively easy and way less harmful to the soil and environment.
- Feeds your garden,
- Activates and improves soil,
- Strengthens plants,
- Encourages plant growth,
- Natural insecticide and fungicide.
1. Place all the above ingredients in a 10L gallon. About half of the gallon is green leaves and other funky goodies.
If you feel like you need to add more ingredients to your biofertiliser you can also try these:
Molasses (third boiling cycle in the sugar making process) provides an effective, available source of carbon energy and carbohydrates to feed and stimulate the growth of beneficial micro-organisms. The biodiversity in your soil will flourish and enhance the natural soil fertility. If you don’t have molasses then maybe try brown sugar or honey.
