Never use these fertilizers: unnecessary substances that have no impact on the crop
Homemade fertilizers can be a good way to nourish plants in the garden. However, as with any information from the Internet, it is crucial to be cautious with recipes, as some life hacks and tips can be harmful.
OBOZREVATEL has compiled a list of homemade fertilizers that will not benefit plants and may even be harmful, despite being natural and seemingly a good alternative to commercial fertilizers.
Eggshells
While the shell contains a significant amount of calcium carbonate, beneficial for the soil, the issue is that the solid substance decomposes slowly, releasing the substance to the ground too slowly. Therefore, there will be practically no benefit from such fertilization. The only way to derive some visible benefit from the shell is to grind it into a very fine powder, a quality that is almost impossible to achieve by hand.
Banana peel
As with any organic fertilizer based on plant parts, the problem with banana peels is that it is impossible to accurately calculate the nutrients they contain. Therefore, the effectiveness of such fertilization is quite unpredictable. Additionally, bananas, like any fruit transported over a long distance, are treated with numerous chemicals to prevent pests and spoilage. These chemicals can leach into the soil and may not be beneficial to the crop.
Iodine
Fertilizing plants with iodine will not provide significant benefits, as plants typically obtain the necessary amount of this substance from the soil.
Baking soda
This alkaline agent can significantly alter the soil composition, making it less acidic, which plants may not prefer. Therefore, it is better to refrain from using baking soda as a fertilizer.
