Fish Emulsion & Fish Meal
Fish Emulsion is the fast action plant starter for the cold early months. Fish EmulsionSource - it is processed from fish food industry waste. Fish should not be caught specifically for making fertilizer, especially fish from depleted fish stocks.Fish waste is cooked and the oils extracted to prevent rancidity and aid transport. Processing may involve the addition of sulphuric or phoshoric acids to stabilise the product and prevent premature break-down. This provides additional nutrient value. I haven't discovered a supplier on the internet. Fish Emulsion is probably locally available near to sea ports. Analysis - nitrogen 4, phosphorus 1, potassium 1, sulphur 5, and trace elements. Application And Rate - 1 Tablespoon of Emulsion per gallon of water. Can be applied as a folia feed followed by a good watering of the soil to give root growth a chance. Apply with Seaweed Extract. Release Rate - rapid. Timing - especially useful for giving plants a good early start when the season is still cold. At this time alternative organic sources are slow to be released. Do folia feeding early morning or evening but not in full sun. Action On Plants - Phosphates promote root development and nitrogen is used to make plant protein. As release rate is rapid some advisors say there's a chance of leaf burn. I think this unlikely in the colder early season and when the roots are well-watered at the same time. Fish Emulsion also supplies important trace elements for total plant health. FISH EMULSION IS USEFUL FOR
Compare Fish Meal
Fish MealSource - raw fish should be sourced as described above.The dried fish scraps are made by different methods into several fertilizer products. Sometimes it is composted and sometimes spray-dried fish protein is made by low temperature drying. This gives a fine powder easily digested by bacteria to nitrates which are readily available to plants. Highly processed fish by-products can be expensive as fertilizers, so most go to animal feed. Availablity may be localised following gluts in fish waste when less costly processing methods may be used. Analysis - nitrogen 6-12, phosphorus 3-7, potassium 2-5. Application And Rate - 7oz per square yard. Work into the soil. The meal can also be dissolved in water but it should be kept stirred up as it is not as soluble Fish Emulsion. Persists for 6 - 8 months. Soil Reaction - acidic. Action On Plants - a good general fertilizer for growing nitrogen hungry vegetables. Its acidic soil reaction makes it less suitable for cabbage than Fish, Blood and Bone. Phosphates for root growth and potassium for flowers and fruit add some nutrient balance. Onion described by some as a leafy root crop would probably benefit. FISH MEAL IS USEFUL FOR
