Farmers in multiple regions are increasingly turning to alternatives to conventional nitrogen fertiliser as a supply crunch tightens access to products such as urea. Reporting links the shortage to disruption effects tied to the Iran war, which affects portions of the global fertiliser supply chain and raises concerns about availability and cost. One outlet notes that around a third of traded urea—widely used for nitrogen—originates from the Gulf region, making markets sensitive to instability there. As conventional nitrogen inputs become harder to secure, some farmers and associated producers are adopting practices that use waste-derived nitrogen sources. Coverage describes demand for urine-based fertiliser products and other organic alternatives, including manures, as substitutes when standard fertilisers are scarce. The shift reflects broader pressure on agricultural inputs and the search for lower-cost or locally available nutrient sources. While urine and manure-based products can provide nitrogen, the articles focus on the supply-demand pressures and the move toward alternative nutrient options rather than on comparative agronomic performance or regulatory changes.
