What is the Best Fertilizer for Organic Gardening?
In recent times there’s been a fairly blatant paradigm shift from chemical and artificial food production to organic and natural food production. This is a result of the new awareness being created about living and eating right. So many prevalent diseases have been linked to the increased number of chemicals
imbibed through foods and drinks, both knowingly and unknowingly.
Many of the fruits served in many expensive fruit bowls
in homes across the world or which are juiced with the best juicers
were grown on lands manured with artificial fertilizers. Eating or drinking these can be dangerous to our health.
Inorganic or chemical fertilizers, inasmuch as they increase plant yield
, have been proven to have more disadvantages than their seeming ‘advantages.’ Artificial fertilizers have been found to be major sources of soil and water pollution, leading to soil degradation and changes in pH of both land and sea.
An organic fertilizer is derived from purely natural resources, mainly animal and plant by-products. A few of them are produced from rocks and naturally occurring ores. There is really no serious disadvantage associated
with using an organic fertilizer for planting, unless you count in its typically off-putting smell or the fact that they are not as concentrated and may take longer to act. It promotes healthy and stronger development of all plant part, from the root to the foliage while at the same time improving and adding to the soil by replenishing its natural nutrients and biomass.
Using organic fertilizers in your garden ensures you get the better tasting and bigger fruits and vegetables with more nutrients than you could get from an inorganic fertilized garden while giving back to mother earth and nature. Organic fertilizers can be used for all plants, including lawn grass.
While we’re focusing on organic fertilizers, which are especially important to those who grow gardens or farms, you might be interested in artificial plants
just for decorative purposes.
Now let’s take a close look at some factors you need to consider when buying an organic fertilizer such as the major component source, the form of the fertilizer, the pack size, the action mechanism, and quite naturally, the cost. By the end, we think that you will agree that making organic part of your lawn and garden routine
simply makes sense!

For every purchase you plan on making, there’s usually a price range which you wouldn’t want to exceed. Most products have high-end and low-end categories (and many in-between). Depending on the type or category of product and the features you’re looking for, you’ll most likely see the product in different variations, having different prices and features.
In this review, we covered all price categories, bearing in mind that there are very good products that aren’t so expensive. In any case, you’re assured of quality products from reputable brands in this review.
The price range for the organic fertilizers under review here is between $7.19 and $26.00 which is quite broad and well within most budgets. During the course of our research, we encountered several cheap organic fertilizers, but we dismissed them because they’ll likely not give the desired results. A good quality fertilizer is especially important for any raised garden plan
due to the fact that all the nutrients are concentrated in a smaller area.
Thus this review is solely focused on high quality and high performing organic fertilizers. Keep reading.
Organic fertilizers have undergone some changes from the typical unsightly and smelly substances that they were known for to being well-packaged modern products with a refined look. There are some factors you need to consider if you’re going to buy a high performing organic fertilizer.
These factors include:
- Major component and its source
- Pack size
- Action mechanism
- Additional information
Construction and Design
Organic fertilizers are formulated from 100% natural sources or materials. Most of them are composed of microorganisms or animal and plant by-products. There are still some made from naturally occurring ores and rocks. Those composed of microorganisms usually blend in different types of beneficial microbes and microorganisms that break down nutrient materials in the soil, making them readily available for plant uptake and utilization. The type formulated from animal and plant by-products adds decomposed and bio-available nutrients to the soil, enriching the soil and increasing the nutrients available to the plant. The organic fertilizers from naturally occurring rocks and ores are extremely rich in trace mineral elements which work by altering the biological processes of plants, improving and increasing their rate of nutrient uptake and utilization. So checking the major component of the organic fertilizer you want to buy is advisable, so you can have a fair idea of what to expect.
Most organic fertilizers in the market come in different pack sizes – there are the small packs of between 3-pounds – 9-pounds, medium packs of about 12-pounds – 16-pounds and the bulk sizes of up to 50-pounds in weight. An organic fertilizer is not an item you’ll want to store for an extended time, given that most of the microbes in the formulation are live organisms, so you’d be better off buying a pack size that’s commensurate with the size of your garden.
Organic fertilizer can be in granular, micronized or liquid form, with the most common form being the granular type. The form of an organic fertilizer does have a direct relationship with its application. The granular form is most often applied directly to the soil either while tilling or when the plants must have grown to a certain height. The micronized or powdered form is used mostly for coating seeds before planting to decrease the time taken to germinate. The liquid form can be sprayed unto the plant base or added to the water before watering the plant.
Some organic fertilizers are formulated for specific plants while a good number of them are general-purpose organic fertilizers. So if you need an organic fertilizer for any particular plant, there’s every possibility that you’ll find it. We have quite a few of the specific-type organic fertilizers in our individual product review section.
Performance and Ease of Use
Most organic fertilizers are pre-mixed. This means that you don’t have to mix it again, just open and apply. Although some of them may come with an instruction with regards to how to apply or what quantity to apply, there’s really no need to fret as there’s nothing like plant burn out due to over application; unlike the case of an inorganic fertilizer, there’s no need to measure carefully before applying to the plant to avoid burning the plant. Whatever quantity you choose to apply on your plant when using an organic fertilizer is solely based on your discretion and how much fertilizer you’re willing to use up for your garden.
Organic fertilizers are high performance substances because the components are natural and have been engineered to immediately get to work once they’re incorporated into the soil. Most of them have a slow release mechanism which closely mimics the natural plant feeding method by slowly and continuously releasing nutrients for plants to assimilate. This mechanism also prevents the leaching away of valuable nutrients. The trace mineral elements in these organic fertilizers work by developing plant roots to be stronger and bigger so they can take up and hold more water and nutrients from the soil and also facilitating the quick utilization of the nutrients by the plants.
Because the organic fertilizers provide readily available and quality nutrients to plants and also help them assimilate faster, they help plants build up their defenses against diseases and insect attacks. This also makes the plant healthier, vibrant and strong and leads to production of bigger and tastier fruits and vegetables.

Organic Fertilizer FAQs
What is organic fertilizer?
Organic fertilizer is an all-natural fertilizer that’s made using animal and plant waste, as well as other natural nutrients in some cases. The main source of materials used to make organic fertilizer are animal wastes especially from slaughterhouses, peat, and treated sewerage sludge. Animal-sourced organic fertilizer includes manure from animals and by-products of slaughtered animals. Plant-based organic fertilizer includes compost and seaweed extracts.
When should I apply organic fertilizer?
This depends upon the type of fertilizer. Due to the extended period of time that many organic fertilizers require to fully break down (for example natural compost or manures), it’s best to apply them several months before planting. The prior application ensures that the soil absorbs all the necessary nutrients needed for plant growth. If you are using a quick acting fertilizer or water soluble fertilizer, those should be applied during the growing season. Since the timing depends upon the type, always check the package for detailed instructions.
How do I apply organic fertilizer?
The most recommended way to apply organic fertilizer is to layer it on the topsoil or the upper layer of the plant bed. Since the roots of plants don’t need to penetrate much into the soil, you don’t need to dig it deep into the ground. There are also some organic fertilizers that come in liquid form which are applied mixed with water.
What is better chemical or organic fertilizer?
Both vary in terms of benefits. Organic fertilizers are typically slow to release into the soil but the great thing is that they don’t form a crust on the soil and contribute greatly to the structure of the soil. Chemical fertilizers are readily absorbed by the soil but in case too much is used, they may burn the soil leading to low yields.
Is organic fertilizer safe for pets?
The answer to this question depends upon what you mean by "safe." Most organic fertilizers are safe for contact with skin, but no fertilizer is safe to ingest by pets. The difference between organic and chemical fertilizers comes in terms of lethality. For example, ingestion of some non-organic or organic fertilizer blends (typically small amounts won't be lethal for the organics) may require an immediate trip to the vet to prevent serious complications such as inflammation of the pancreas or death from poisoning. In general, organic fertilizers are not lethal, but they can still cause side effects such as diarrhea or bowel obstruction. Whenever there is any doubt, regardless of whether your dog or pet has eaten manure, organic fertilizer or a chemical one, seek medical advice or treatment to be on the safe side.
