I’ve often recommended used coffee grounds as an excellent free source of nitrogen and other nutrients plants need, but spent tea leaves are even better. According to a study from the University of Florida, tea grounds are 4.15% nitrogen. That’s about twice as much nitrogen as in coffee grounds. Tea also contains nearly twice as much phosphorus and potassium. The study found that tea grounds have an NPK of 4.15/0.62/0.4, while coffee grounds have an NPK of 2.08/0.32/0.28.

OYR is all about growing a lot of food on a little land using sustainable organic methods, while keeping costs and labor at a minimum. Emphasis is placed on improving soil quality with compost, mulch, and compost tea. No store-bought fertilizers, soil amendments, pesticides, compost activators, etc. are used.
