When we think of the coming season of marijuana farming, it’s likely that we’ll see a shift in fertilization practices. In the past, growers relied on lots of nitrogen and phosphorus to help their plants flourish. But with prices for both Nitrogen and Phosphorus skyrocketing, many growers are now looking to alternative fertilizers to plant their cannabis. And one of the most popular options right now is organic fertilizer.
“People are definitely going towards organic fertilizer because it’s affordable and provides better results than using nitrogen and phosphorus,” said Sherri Zager, president ofinSouthern California . “Organic nutrients are something that’s been used for a long time in agriculture, so there’s a lot of knowledge and experience behind them.”
Zager says that while mineral oils can work well as auxiliaries in soil, they’re not ideal for cannabis because they can have negative effects on resin production and THC levels. Instead, she recommends using mineral-rich plant extracts like rocofurazone or zinc sulphate. However, she cautions that these fertilizers should only be used in diluted form – not superfused directly into the soil – and should always be accompanied by a balanced diet for the cannabis plant.”
Instead of overusing traditional fertilizers, some growers are experimenting with other liquid nutrients like fish emulsion or seaweed extract. So far this season, both Phosphorus 2000 and Miracle Grow have seen an uptick in sales due to these types of nutrient alternatives.”
While there’s still uncertainty about how the U.S. economy will fair over the next few years, it seems clear that cannabis farmers won’t be using as much traditional fertilizer this season as they have in the past.”
