osseous tissue meal , the land - up beast bones left over from slaughterhouses , has long been bluster as an organic fertiliser rich in phosphorous and calcium . say to help stimulate root increase and upgrade stronger plant , this soil amendment has become a pop recommendation for organic gardening . * * While there are welfare to using ivory meal in some veg gardens , several factors should be considered in evaluating its overall shock as a fertilizer . * *
Step 1
works want 16 different all important nutrients . Three are weigh macro - nutrient , because they are need in larger amount : nitrogen ( N ) , phosphorus ( P ) and potassium ( K ) . Fertilizers that are considered " complete " are ones that have all three of these all-important macro - nutrient present . On plant food packaging , their percentage is represent by three numbers , 7 - 7 - 7 , for example , to show that there are equal parts of N , P and K in that fertilizer . * * Bone repast is considered an uncompleted fertiliser , possessing only high levels of phosphorous and just a trace of N , * * around 1 - 15 - 0 , depending on how it ’s processed . It is also gamy in calcium , another nutrient plants need . In garden dirt , however , phosphoric and calcium are usually found in decent amounts unless the stain has been used for several uprise seasons without any fertiliser . Additionally , high levels of phosphorous can actually be toxic to some plants and may reduce the phone number of microscopic fungi that serve establish soil over clip .
Step 2
pH and Phosphorous
The best way to find out if the addition of phosphorous through the lotion of bone repast will be good is to screen your soil . Simple kits , available at garden centers , can detect degree of atomic number 7 , phosphoric and K in grunge , as well as pH — another important agent to take before fertilizing your vegetable garden . The pH scale is used to determine how acidic or alkaline soils are , which can impact the availableness of nutrients and general plant health . Phosphorous from pearl repast is only usable to flora in soil with a pH below 7.0 . The pH of dirt can be amended in a mixture of ways , but in areas with somewhat alkaline soil , os meal may not be the best choice of plant food compared to other animal by-product such as compost or Pisces the Fishes emulsion .
Different Types of Bone Meal
Traditionally , pearl repast was dried and ground from the bones left over from brute processing . In recent years , concern over such pathogen as those that stimulate " Mad moo-cow " disease and salmonella have leave to the material being desex through steam pasteurization . This procedure eliminates the potential risk of disease among stock , but also trim back the suggestion amounts of nitrogen find in traditional bone repast . Commercially uncommitted bone meal will have been sterilized through this outgrowth , though there are recipes for making your own unsterilised osseous tissue meal .
Plants That May Benefit
Plants that benefitmost from the program program of ivory meal are ones that use high levels of calcium . tomato plant , peppers , melon vine , celery and boodle all benefit from extra Ca . industrial plant that do not benefitfrom excess phosphorous admit root harvest like common beet or carrots . obviate using it with plants that use bacterium in grime that avail get nitrogen like edible bean , pea or any other leguminous plant .
Applying Bone Meal
os repast is lend oneself by unify the granular powder into the top layer of soil . As a slow - release fertilizer , nutrients leach into the grease with each tearing . This can be done prior to planting by commix the amount recommended on packaging into soil as you sow seeds or transplantation seedlings . you may also add pearl repast during the grow season bytop dressingwith a granular fertilizer sprinkled evenly on the soil control surface around industrial plant or through * side dressing , * where the fertiliser is laid in a descent just to the side of plants . Try not to touch stem directly with the fertiliser , and urine now afterwards for best results .
