Organic fertilizers are naturally-occurring fertilizers (e.g. peat moss or green manure), or naturally occurring mineral deposits (e.g. saltpeter).
Naturally occurring organic fertilizers include manure, slurry, worm castings, peat, seaweed, humic acid, brassin and guano. Sewage sludge use in organic agricultural operations in the U.S. has been extremely limited and rare due to USDA prohibition of the practice (due to toxic metal accumulation, among other factors).
Processed organic fertilizers include compost, bloodmeal, bone meal, humic acid, amino acids, brassin and seaweed extracts. Other examples are natural enzyme digested proteins, fish meal, and feather meal. Decomposing crop residue from prior years is another source of fertilit

* Make rich fertile soil
* More healthy plants - more healthy you!
You may have been put off organic fertilizers that don't produce the instant results that you're used to. But to make organic gardening work its wonders you need to do the other gardening things too. So as well as links to my fertilizer information, you'll also find more here about how to use and reduce on fertilizer.
Chicken manure especially, as well as fish blood and bone, and other organic stuff mentioned here certainly get results. But they are only one part of what makes my garden blossom and fruit and the cauliflower turn up rich and healthy.
When You Need To Use Organic Fertilizers Most garden soils contain the bare essentials. But for many important garden plants more fertilizer helps.
When growing in containers
you can make good earth for containers from garden compost, loam, leaf mold, perhaps comfrey leaves and fed with specialised organic fertilizer blends,
When growing nutrient demanding crops
Brassicas, potatoes... modern varieties of some plants may be more demanding - composted or dried manure is essential
- Poultry / chicken manure is here,
For plants growing on the same site for long periods
e.g. lawns, shrubs, hedges, trees... garden compost and manure is still a great provider
- More on lawn and shrub fertilizer,
When growing on thin unfertile ground
work in manure - continue to use organic fertilizer to make better quality compost, and grow green manures to dig in. See organic base fertilizer and re-mineralizing rock dust on link here.
In fact, I always add organic fertilizer for important crops and flowers. But I recycle the green waste through compost and also build moisture retentive, increasingly fertile soil. And because I use organic fertilizer (and I'm careful) less damage is done.
Provide Complete Fertilizers - Keep It Simple And Whole
Growing plants need all the major nutrients and more. Don't focus on N for leaves, P for roots, K for... ? Remember that you are growing whole plants, not leaves without roots, or flowers without leaves.
So avoid single nutrient plant foods.
Correct Problem/Deficient Soils
Move the complete range of nutrients from bagged composted manure and organic fertilizers through your plants and into garden compost. Made from living plants, compost contains all the essential nutrients at an ideal ph and so eventually your garden soil will come right.
Manure and garden compost dramatically improve soil condition too. So I can grow more kinds of plants with fewer worries about drainage and water shortage. And as the earth gets richer and deeper I can grow plants with closer spacing and look forward to bigger harvests and more flowers still.
Alternatives To Fertilizer
- Simply water your plants when dry to bring existing soil nutrients to your plant's roots,
Grow your plants with a strong healthy root system,
- Maintain healthy soil that's well-aerated, free draining and moisture holding and you'll help most garden plants to bare flowers and fruit in plenty,
- Soil micro-organisms are important for feeding your plants too,
The organic gardening term 'feed the soil not the plant' recognises all of these benefits. So add organic matter.
- Advantages To 'Feeding The Soil'
You'll be able to grow more types of plant successfully - more free draining, more moisture holding, organically rich, diverse soil micro-organisms support plant growth and condition your soil so it's easier to work, http://www.the-organic-gardener.com
