Phosphorus Concerns In Relation to Cannabis Production

Phosphorus Concerns In Relation to Cannabis Production Professor DeBacco Phosphorus Is an Important Plant Nutrient While phosphorus is needed by the plant growers often apply phosphorus in qualities that the plant can not consume leading to wasting of this nutrient. This creates the potential for environmental contamination and also increased cost with no return on investment. Phosphate Mines Limited Reserves World Wide Only 7 mines in the US with the majority coming from Florida US Mined Phosphate Rock 1900-2015 Amount of US Mined P has shown a decrease since the 1980’s Many would think this would correlate to decreased demand or consumption, however this graph does not tell the full story… US Net Imports Phosphate Rock (1900-2015) While US mined P has decreased over the same time period the US has gone from an exporter to an importer of phosphate rock. This is in part due to the decreased purity of P mines in the US. Why Focus on Phosphorus? This is a nutrient that growers tend to over apply due to the idea that it will induce flowering. So, while important for flowering growers tend to over apply it which is of concern due to the potential problems facing phosphorus in the near future. Limited Resource Phosphorus is a non-substitutable component in all living plants and organisms. This nutrient is crucial element to plant growth and as a result also the food chain. Using fertilizers derived from phosphate rock has made increases in food production possible and reduced malnourishment since the mid-20th century. Recent worries about a future shortage of phosphorus have sparked a debate over the lifespan of existing reserves. Freshwater Contaminate Phosphorus can speed up eutrophication (a reduction in dissolved oxygen in water bodies caused by an increase of mineral and organic nutrients) of rivers and lakes. Soil erosion is a major contributor of phosphorus to streams.
