Composted and non-composted Organic Fertilizer
Organic fertilizer is considered free from artificially added chemicals and other elements that are harmful to plants. However, organic fertilizer, such as chicken or cow manure, users can either be composted or not composted. There is a difference between these two types of fertilizer. Fresh and not composted manure can be applied to plants that require a high level of nitrogen. However, applying fresh and not composted manure to plants possess a health risk.
The not composted manure contains bacteria and pathogens such as salmonella and E. coli. These bacteria and pathogens are in fact harmful to humans. Although they are not taken up by the plant roots, some of these bacteria and pathogens can stick to the plants and can be brought to the kitchen along with the plants. These can then enter the cooked food and harm humans. Also, some vegetables such as cabbages and salads alongside fruits are not cooked before consumption. Therefore, this can also affect consumers.
Dried and processed manure is sold in hardware stores. These types of organic fertilizers are safer in comparison homemade with non-composted manure fertilizer. However, if you wish to make the fertilizer at home, the following steps can be followed:
- Make sure to dry the manure in high temperatures of 55 degree Celsius and above for at least 15 days
- Another way is to dry the manure for 6 months to 1 year in order to kill the pathogens and bacteria
When properly composted, organic fertilizer made at home from manure can be very beneficial over the chemical-based fertilizers. It also helps save the cost of maintaining your backyard garden.
