Plants need nutrients, including nitrogen, phosphorus and potassium, and these are ingested through the food we eat, excreting them, mostly through urine , French experts say.
Human urine may seem like a crude way of fertilising plants in the era of industrial agriculture, but as researchers look for ways to reduce reliance on chemicals, some are growing increasingly interested in the potential of pee.
Plants need nutrients to grow. Agriculture relies heavily on chemical fertilisers to provide these nutrients. But what if we tell you we can use pee instead?
Yes, urine might be the solution to all our problems. Before we talk about how it can help let's see why a shift from chemical fertilisers is necessary.
Nitrogen, phosphorus, and potassium are essential for plants and hence agriculture.
