Best Organic Fertilizer
Did you know that majority of the nutrients in your food originated from the soil? Yes, you heard it right. The nutrients of the vegetables and crops we consume are highly dependent on the soil’s condition.
When the soil does not have enough nutrients, we need organic fertilizers to augment this deficiency. The reason why an organic fertilizer is better than a synthetic one is that the former provides plants with the needed secondary and micronutrients.

Things to Consider for Choosing Organic Fertilizer
Why Organic is Better than Synthetic?
Organic fertilizers are those that are extracted naturally from plant-based materials and animal by-products. Synthetic or inorganic fertilizers on the other hand are man-made fertilizers that are commonly derived from minerals, gases, and other inorganic materials. Organic fertilizers are obviously a better option in a number of aspects as shown below.
As mentioned earlier, healthy soil is key to having a nutritious crop yield. Organic fertilizers do an excellent job of improving soil structure and its capacity to store water and nutrients.
They break down and release nutrients and microorganisms to your soil as they decompose. The improved quality and texture of the soil will enhance the plant’s overall health. The water retention of the soil will also be greatly improved over time.
Organic fertilizers work by slowly releasing the nutrients to the soil to avoid overfertilization which harms your plants. Since the nutrients are in their natural state, it consumes more time, considering also other factors like warmth, moisture, and the weather.
Synthetic fertilizers are often in fast-acting formulas which immediately provides the nutrients to the plants and stimulate their growth rapidly. You would need frequent application since it is consumed faster. Aside from this, the quick nutrient buildup can lead to plant death.
In everything we do, we should look at what it can do to the environment. Organic fertilizers are generally safe to the environment and are considered biodegradable, renewable, and sustainable. Since ingredients are naturally made with minimal processing, zero chemicals are involved which means good news for mother earth.
Inorganic fertilizers come from inorganic matter and undergo heavy processing to arrive at a specific ratio of nutrients. The processing itself poses harm to our environment because of the chemical add-ons and increased consumption of water. Frequent use of these fertilizers will result in an accumulation of toxic chemicals in the earth which will eventually result in long-term damage.
What to Look for in an Organic Fertilizer
Before we look around for different brands of organic fertilizers, it is important to know what are the essential nutrients and micronutrients needed for your soil.
The six main nutrients that the soil needs are carbon, hydrogen, oxygen, nitrogen, phosphorus, and potassium. The first three nutrients are produced naturally from the environment through air and water. For the other three nutrients, normally given the acronym NPK, they will depend on the soil’s existing soil nutrients. If deficient, this is where an organic fertilizer comes in.
This nutrient is considered one of the most important nutrients because it helps in the production of new plant tissues. Nitrogen is a component of chlorophyll and is the agent responsible for giving the plants their green color. Plants need nitrogen for enhancing flower and fruit quality.
This function of this nutrient cannot be shouldered by any other nutrient. It plays a crucial role in the optimal growth and reproduction of your plant. Phosphorus also contributes to photosynthesis, energy transfer, sugar transformation, and nutrient movement.
Potassium is an indispensable nutrient for the survival of plants. It aids in photosynthesis and in efficiently managing the opening and closing of stomata for light regulation.
Aside from the primary nutrients, these nutrients also beneficial the growth of plants:
Plants need this nutrient for their cell membranes and to neutralize the effect of toxic materials. Furthermore, a good amount of calcium can improve the structure of the soil and helps in binding both organic and inorganic substances together. It is also responsible for activating enzymes and the coordination of cellular activities.
Magnesium is a fundamental component of chlorophyll. It acts as a carrier of phosphorus in the plant and is important for phosphate metabolism. It also plays an active role in protein formation, cell division, and activating different enzyme systems.
Although it is needed in small amounts, the absence of sulfur will have a detrimental effect on your soil. These nutrients condition your soil by reducing its sodium content. They are a key component of certain vitamins and enhances the flavor of onions, mustard, and garlic. Generally, the soil is deficient and sulfur and this is where an organic fertilizer will do its job.
To fully boost the overall health of the soil, the following micronutrients are needed in tiny amounts:
The abovementioned nutrients – primary, secondary, and micronutrients – all play a crucial role in making your soil health and consequently enhancing your plant’s growth. Take note of these nutrients and make sure that the organic fertilizers you will buy contain a well-balanced composition of these nutrients.
All of the organic fertilizers have their own share of strengths and weaknesses. However, the clear winner of this close battle would be Burpee Organic Bone Meal Fertilizer. It is an excellent source of all the major NPK nutrients, namely Nitrogen, Phosphorus, and Potassium. What’s convenient is that it comes with a 3-lb packaging that allows you to purchase based on what your current lawn area.
Next in line would be the Milorganite 32 lb. Slow-Release Nitrogen Fertilizer. It primarily contains slow-release nitrogen and comes with a large packaging that would be a value for money.
The first runner-up would be a tie between Down To Earth Organic Feather Meal Fertilizer Mix and Espoma EOFW30 Organic Fall Fertilizer since both are still powder-based and easy to apply. Last on the list, but definitely not the least, would be Advanced Nutrients Iguana Juice Grow Organic Fertilizer because of its liquid form. Although it is easy to apply, it is prone to wastage, and once opened, you need to close it properly.
