![]() ![]() When London switched to natural gas and electricity, the smog decreased and now if you re-run the experiment, there is no change in the need for nitrogen regardless of season. Research done at Kew in those days worked its way into old gardening books. The smog was so heavy in nitrous oxides and various sulfur oxides that rain washed enough nitrogen into the soils that during the heating season no nitrogen was necessary to fertilize London gardens. In fact the old screwed up idea of a low nitrogen, high phosphorous fertilizer need in autumn, came from 1850's to 1890's London, where all the homes were heated with coal. ![]() Nitrogen can also come from air pollution. the fish emulsion (Alaska) 5-1-1 is mostly fish scrap/guts and it. the difference is one is made with no heat (the hydrolyzed), meaning most of the vitamins, oils, amino acids are preserved. Rain will wash significant amounts of sulfur out of the air onto our bonsai pots and supply much of the sulfur our trees need. the original post is old, but ill share my 2 cents in case anyone cares to know the difference: both 5-1-1 fish emulsion and the hydrolyzed fish are great. Municipal and well water systems are often quite high in calcium and magnesium so we don't need to supplement them. Despite the minor cons related to dilution and smell, I truly believe that this fertilizer is a must-try for any gardening enthusiast. After testing it on various plants with excellent results, I give Neptunes Harvest Fish and Seaweed Liquid Fertilizer a well-deserved 5/5 stars. Much of the calcium and magnesium needed comes from our water we use to water our bonsai. Overall Rating of Neptunes Harvest Fish and Seaweed Fertilizer.
