How long does organic fertilizer last?
In a retail setting, where the temperatures remain consistently around 70 degrees Fahrenheit and the products are away from direct sunlight, organic liquid fertilizers can usually remain stable up to five years or sometimes longer . It’s when the product is taken home by a customer and the seal is broken that the shelf life dramatically decreases. Once fresh air is introduced into the bottle, the effectiveness of the stabilization process can begin to erode. In an effort to prolong the storage life of an opened bottle for as long as possible, always store the product in a relatively cool area, void of direct sunlight. Heat and intense sunlight are most often the number one reasons why organic liquid plant nutrients go bad. Also, do not allow these types of products to freeze. Freezing will most definitely ruin the composition and solubility of the mixture. If an organic product does become active in the bottle and begins off-gassing or ballooning, it doesn’t directly mean that it has gone bad in the sense that it cannot be used. In this case, slowly remove the cap and carefully inspect the product. If there is visibly noticeable fungal growth, then I would advise not using the product because there is no clear way of knowing if the fungi will be beneficial or detrimental to the plant and root growth. Likewise, if the smell is abnormal or rancid, it is best to replace it with the new product and to dispose of the bad product properly. Liquid products that contain both organic and inorganic ingredients usually don’t meet NOP standards and will often have a chemical preservative to maintain stabilization over a longer range of time and conditions. Even so, these products should be treated and stored in the same fashion as true organics to ensure their maximum storage life.
Why is mineral fertilizer so soluble?
