Many people agree that organic fertilizers are much safer and more beneficial than chemical ones. But, is that really true? Certainly, using organic fertilizers on your crops has many benefits. However, not everything that’s said about them is true. In fact, some organic fertilizers on the market can end up ruining all your hard work.
In this buying guide, you’ll learn some tips that will help you differentiate a good fertilizer from a bad one. Also, you’ll find a list with some prohibited components that you should avoid in order to prevent soil contamination.
Above all, organic fertilizers should be safe for animals and humans. So, if you notice any warning notes like “keep away from children and animals”, it’s recommended to reject the product. Probably, not all the components of the formula are 100% organic.
In fact, some “organic fertilizers” contain large concentrations of chemicals to increase their effectiveness. It’s also true that some natural products contain allergens like sesame oil or fish meal that can cause unwanted reactions.
Before buying any chemical fertilizer or organic fertilizer, check out the ingredients of the formula. If you aren’t an expert in chemicals, research on the Internet if they’re really safe for humans and pets and their effects on the body.
Chemical vs. Organic
It isn’t a secret to anyone that chemical fertilizers can be dangerous. It’s well known that prolonged exposure to these products can cause cancer and problems during pregnancy. However, despite all their cons, it’s also true that chemical fertilizers are quite effective.
Chemical fertilizers have two major advantages in contrast to chemical products. First of all, they’re highly concentrated. Therefore, a small dose is sufficient to fertilize huge growing areas. Second, they can be easily mass produced in a short time. This also makes them considerably cheaper than organic products.
In addition, chemical fertilizers don’t alter the color or flavor of fruits and vegetables. So, they can guarantee consistent results in different harvesting seasons.
Organic fertilizers on the other hand are relatively harmless in contrast to chemical products. However, mass production takes more time, especially those based on compost.
It’s also true that most organic fertilizers have a strong smell. That’s because of the smelly nature of their components, like guano, feather meal, blood meal and fish meal. Bad odors can also attract flies and other nasty insects. So, using organic products will also increase the consumption of pesticides.
Compost-based organic fertilizers contain both good and bad microorganisms. Therefore, it isn’t good to exceed the recommended dosage. If you do, you may cause other serious problems like fungus proliferation.
Some artisanal fertilizers lack of quality certifications and distribution permits. In some cases, it’s impossible to know where and when these products were manufactured. Irregularities like these are very common in many products sold on the Internet. Therefore, you must be very careful before buying fertilizers for the first time.
In addition, some of these fertilizers contain highly polluting substances that can pass into water bodies. According to The National List of Allowed and Prohibited Substances from the USDA, you should avoid fertilizers with any of these ingredients:
- Sodium fluoaluminate (mined)
- Potassium chloride
- Calcium chloride
- Wood ash lye soap from manure burning
- Lead salts
- Sodium nitrate
- Tobacco dust (nicotine sulfate)
Some of these ingredients may be disguised behind complex chemical compounds. Therefore, research each component of these compounds on the Internet to verify that the fertilizer is 100% safe. Also, if you notice a strong manure odor on the product, reject the product immediately.
In case you use any chemical or organic fertilizer, make sure the crops are away from rivers and lakes to prevent contamination.
Each fertilizer manufacturer has its proprietary combination of ingredients. However, there are three basic components that can’t be missing from any formula. They’re:
Nitrogen is especially effective in green-leaf plants. Its basic function is to promote growth and intensify color. However, if applied excessively, it may interfere with flower and fruit development. Nitrogen is usually applied in high concentrations during early stages of growth.
On the other hand, phosphorus promotes root growth and the production of flowers, fruits, and seeds. It also provides a brighter and healthier look to fruits.
Potassium helps to strengthen the natural defenses of the plant, making it more resistant to external agents. It also promotes cellular development and carbohydrate metabolism. As a result, fruits grow bigger than normal.
The NPK numbers are those ones that you usually find in the bags of most commercial fertilizers. For example, “10-10-10” or “4-5-2”. Each number represents a percentage of the total weight of fertilizer. Each number is read as follows: “nitrogen-potassium-phosphorus”.
At a “10-10-10” concentration, 10% by weight is nitrogen, other 10% is potassium and the other 10% is phosphorus. This is also known as a balanced formulation, because all the concentrations are equal. On the other hand, if at least one of the NPK numbers is “0”, it’s an incomplete formula because of the lack of a certain nutrient.
Choosing the right formula isn’t easy. You should first know the requirements of your crops. For example, in the early stages, it’s recommended to apply more nitrogen to strengthen the roots. However, if the soil is already rich in nitrogen, you would be affecting the normal growth of the plant.
The excess nitrogen would force the plants to produce more foliage but fewer flowers and fruits. On the other hand, a low nitrogen level would make the leaves look pale and yellowish.
If you don’t want to rely on trial and error to determine the exact amount of required organic nutrients for soil, make a soil test, organic nutrients for weed, best organic flowering nutrients. That way, you can easily determine how much nitrogen, phosphorus and potassium is necessary to achieve optimal plant development.
