Why should you buy them when you can make your own organic fertilizer biomass? Contrary to popular belief, it's very easy to do, not to mention fun and a great interactive activity to share with families and friends.
To start off, you need to gather all the materials that you're going to need for your fertilizer. For one, you need plenty of organic materials that you're going to decompose. In a neighborhood, there's a good chance that you can gather falling leaves, twigs or small branches, foods with molds or have a lot of fat, and manure.
You may also need to add some components that are highly rich in minerals. One of the most common materials used is lime, which comes in two kinds. You have the dolomite and the calcitic. The latter contains only calcium carbonate, while the former has an additional magnesium carbonate. Compost will only need a little magnesium than calcium, so a good ratio for your lime will be a third of a dolomite and the rest will be calcitic.
Another is rock phosphate. As its name implies, it contains phosphorus. It is usually preferred over a bone meal, since you can have your soil enriched with the mineral for a very long time.
Don't forget the garden soil and water. Moreover, since aerobic digestion is being used to produce the organic fertilizer, you need to find a place where there will be a lot of sunlight and air.
Then, you need to have your compost bin. The size of it will depend on how much fertilizer you're going to need. Some would make use of a pail to keep all these organic matter together. However, if you want to produce fertilizer for your garden, you may need a much bigger one. You need to remember that composting does take time.
Once you have all the materials ready, you can now assemble them into different layers. The process would usually begin by segregating your collected organic material into green and brown layer. You need the green layer since it encourages the creation of other types of nutrients. Green layer may include coffee grounds, manure, and scraps of food. The brown layer will be the main source of fiber for your compost. These are weeds, sawdust, hay, cardboard, and dead woods or flowers.
The ratio for creating the most ideal organic fertilizer will be 1:3. This means that in every set, you have 1 part green and 3 parts brown. Make sure that you can sprinkle these layers evenly into the compost bin. Subsequently, sprinkle water on top of them and cover everything with soil.
Regularly combine the ingredients. After around 3 weeks, you may see some changes in your compost. It color may change to something darker, close to being brown, and it will give off a very strong scent.
You can then use the organic fertilizer to your garden. You can expect your produce and flora to grow so well because your soil is now rich in vitamins and minerals.
