One of the reasons that Vermicast or Vermicompost make such an effective fertilizer is because of the multitude of beneficial micro-organisms that are present in the finished product. By far the most numerous of these are bacteria but the various fungi and molds also contribute. Most people think of these later as having a negative impact, after all we routinely discard moldy food. In fact plants need certain fungi in order to absorb nutrients. Just as we use beneficial bacteria to digest our food so does a worm. The simplicity of worm digestion allows a direct path for organic nutrients to go from waste to soil. Beneficial bacteria are the main engine behind the composting of all organic matter, the worms simple add high octane gas to the mix and speed up the job. During digestion the worms mix and blend compost, micro-organisms and standing nutrients into a tidy little packet of perfectly conditioned soil. These casts or worm manure are hands down the best organic fertilizer around.
The most important duty of any fertilizer is nitrogen fixation and Vermicast does this naturally.
All life on Earth relies on some Nitrogen fixation because it is essential in the biosynthesis of the basic building blocks of our corporeal existence, RNA, DNA, amino acids and proteins would not exist without this fundamental chemical interaction. Atmospheric and elemental nitrogen are inert and don’t easily react with other chemicals, it’s difficult to break the bond of this simple element. Naturally occurring bacteria can do it, they are called diazotrophs and Vermicast has them in high concentrations. This is just one of the advantages to worm cast as a fertilizer, natural nitrogen fixation. Today we have looked into bacteria but this is indeed a complicated story. Next post we’ll discuss some of the benefits gained from potassium and phosphorus in Vermicast.
