Following on from last month's episode, here we continue to explore the potential of Plant Growth Promoters (PGPs). This information may be particularly timely in light of the massive price hike in NPK fertilisers and farm chemicals – perhaps it's now time to consider alternative yield-building strategies. In this episode, we focus upon chitinase and the capacity of this enzyme to boost protection and production. We will also look at liquid vermicast, and the exciting potential of this low-cost, DIY inoculum, as a PGP. The human health component further illuminates pathways to avoid the death of desire. Here, we will consider the health and longevity benefits integral to the reclamation of lost libido.
