According to the calendar, it's supposed to be Spring.
Unfortunately, the weather here in central Indiana
does not want to cooperate since the forecast
for this weekend is 6 to 10 inches of snow.
This too shall end and warmer weather will be right around the corner
With that in mind, I'm sharing with you
an article from Hobby Farms about using
natural fertilizers and not chemicals.
These 10 fertilizers come from natural sources and can help improve 
the fertility of your soil and the nutrition of your crops. Before you 
add a fertilizer—natural or otherwise—to your garden bed, it's advised 
that you have your soil tested for nutrient levels and 
pH.
It's especially important to know the pH level before adding 
phosphorous fertilizers because phosphorous is only available at a 
fairly limited pH range. Adding more phosphorous to an area with the 
wrong pH will tie up the nutrient in the soil and not make it available 
to the plants. Not too mention, excessive nutrients can add to run-off 
problems and create pollution issues.
If you're an 
organic farmer,
 be sure the fertilizer brands you use are on the Organic Materials 
Review Institute's approved materials list. However, for home gardeners 
or small-scale farmers who aren't certified organic but want to use only
 natural fertilizers, all of the following fertilizers are considered 
organic, even if the particular brand you use isn't on the list.
1. Fish emulsion and hydrolyzed liquid fishProcessing
 fish or fish byproducts with heat or acid treatments creates fish 
emulsion. Fish emulsion is generally a pretty stinky fertilizer, but 
it's a good source of all three macronutrients—nitrogen, phosphorus and 
potassium—with an N-P-K (nitrogen-phosphorus-potassium) ratio of 5-2-2.
Hydrolyzed liquid fish fertilizers are created using enzymes rather 
than heat. The resulting product is not smelly and retains more trace 
nutrients and vitamins. The average N-P-K ratio for hydrolyzed fish 
fertilizers is 4-2-2.
2. Bone mealA byproduct of 
slaughtering facilities, bone meal is created through the steam 
processing and pulverization of animal bones. Bone meal is an excellent 
high-phosphorus fertilizer with an average N-P-K ratio of 3-15-0. The 
phosphorous in bone meal takes a few months to become available to 
plants via microbial processes in the soil. It also contains calcium, 
another essential plant nutrient. Phosphorous is most available in soil 
with pH between 6.0 and 7.0, so be sure to test and adjust soil pH if 
necessary.
3. CompostBoth commercially produced compost and 
homemade compost
 benefit soil by adding organic matter, providing food for beneficial 
microbial life, increasing the soil's water-holding capacity and 
gradually releasing plant nutrients. Composts made with high amounts of 
manure or biosolids (sewage sludge) may be high in salts and can burn 
plants, but composts made with primarily plant residues do not generally
 contain troublesome amounts of salt. A typical N-P-K ratio for compost 
is 2-1-1, though its exact nutritional content depends on many factors. 
Compost that smells like ammonia or is not yet fully decomposed should 
be allowed to finish breaking down to avoid damaging plants. Compost 
also contains many micronutrients essential for plant growth.
4. ManureThe nutrient content of 
manure is dependent on many factors, including its age, source and the 
presence of bedding materials. Because of potential pathogen exposure, 
raw manure should be avoided. Manure should be a minimum of 180 days old
 or fully composted before it's added to growing areas. In addition to 
containing macronutrients, manure is also a great source of several 
trace nutrients essential for plant growth.
Most 
cattle and 
horse
 manures have an average N-P-K ratio of 1-0.5-0.5 while poultry manures 
tend to be better high-nitrogen fertilizers (3-1-1 on average). The 
nutrients in manure are not immediately available to plants and can take
 up to several years to be released by soil microbes. In general, about 
half of the total nitrogen is available the first year, with the rest 
being released slowly over several subsequent seasons. Manure is also an
 excellent source of organic matter but can contain weed seeds.
5. Rock phosphateA mineral rock 
powder, rock phosphate is an excellent source of phosphorous, with an 
N-P-K ratio of 0-2-0. The phosphorous contained in rock phosphate 
becomes more available the second year after application, and 
phosphorous is most available within the soil when the pH ranges between
 6.0 and 7.0. Be sure to test soil pH before adding rock phosphate. It 
is also a good source of calcium.
6. Cottonseed mealCottonseed meal
 is a high-nitrogen fertilizer with an average N-P-K ratio of 6-0.4-1.5.
 It takes several months to be processed by soil microbes and broken 
down so that it can release the nutrients it contains. Organic farmers 
should seek out organic cottonseed meal because cotton is often a 
genetically modified crop and many pesticides are used during its 
growth.
7. Alfalfa mealWith an average 
N-P-K ratio of 2-1-2, alfalfa meal provides plants not only with these 
macronutrients but also many trace nutrients. It takes one to four 
months to be broken down by the soil microbes and for the nutrients to 
become available.
8. Blood mealA byproduct of 
slaughtering facilities, blood meal is a very high-nitrogen fertilizer 
with an N-P-K ratio of 12-0-0. Because of its high ammonia content, 
inappropriate use or over-fertilizing could cause burned foliage.
9. Feather mealAlthough it takes 
four months or longer to break down and release its nutrients, feather 
meal is a great high-nitrogen fertilizer with an N-P-K ratio between 
7-0-0 and 12-0-0. It is a byproduct of poultry processing.
10. Liquid kelpAlthough the 
amounts of nitrogen, phosphorous and potassium contained in liquid kelp 
are minimal, it is high in essential trace nutrients as well as plant 
growth hormones that accelerate plant growth and improve flowering. 
Liquid kelp is created through the cold processing of this ocean plant. 
It is mixed with water and applied to plants both as a soil drench and a
 foliar spray. The nutrients it contains are available immediately for 
plant use.
