So what good will it give you after harvesting red wiggler worm castings? Well, castings from red wiggler worms can be beneficial for a lot of things. Not only are you going to benefit from it, your plants and soil will do too.
Now when red worms are used for composting (also known as vermiculture technology), they’ll later on produce what we call, castings (also known as worm manure). These castings then turn into a quality-made earthy substance, which contains a lot of nutrients; given that red worms only feed off of organic wastes that typically contain nitrogen, potassium, calcium, phosphorus, potash, and magnesium. So as soon as this worm by-product is excreted, this can then be used as an organic fertilizer (or as a liquid fertilizer which can also be recognized as worm tea) for your plants, or as a soil conditioner.
So how are castings from worms exactly produced? It’s quite easy actually. Of course, you’ll need red worms for your composting project; and a worm bin for where to keep them in. You’ll be feeding and raising worms all at the same time, so you better keep all these maintained, and well taken cared for. So as soon as you’ve prepared a moist bedding for your worms (can be composed of peat moss and some coconut coir), you can then start placing in your worms. Now when your red worms are finally settled in, you can now feed them with some organic wastes. You can feed them selected kitchen scraps, some garden wastes, and some days old animal manure. And if you want your red worms to produce some good vermicast, then you’ll have to avoid feeding them meat, dairy, and oily stuff (these may attract unwanted pests and also lead to bad odor build-up). Needless to say, if you regularly monitor the worm bedding and food supply, and of course your red worms, then you’re likely to produce great results later on.
Now, worm castings also has a lot of benefits to it. This worm by-product, when used as an organic fertilizer, can help balance the pH of the soil. Not only that, it can also work as a soil conditioner; and can also help the soil with its water-retention capability. But other than that, it’s a resource that can be replenished; and is also safe to use. With this, you’ll no longer have to resort into using chemical fertilizers that can pose danger to many living things (humans, pets, plants, and of other beneficial microbes included in the bionetwork).
So you see, using and harvesting red wiggler worm castings (red worms are also known as eisenia fetida) can be financially rewarding, as you’ll no longer find the need to buy those chemical based products. It’s also neutral-smelling, and is very safe for the environment.
