advantages and disadvantages of fertilzers
Answers
advantages. In nature, decomposition of organic matter creates a natural fertilizer. Applying organic compost or well-aged herbivore manure adds nutrient-rich organic material to the soil, improving quality and texture. Adding organic material to the soil increases its ability to hold water; reduces erosion from water and wind; decreases compaction and crusting of the soil; and raises soil pH. A study at Virginia Tech comparing organic or inorganic fertilizers determined that organic fertilizer is the better choice. Creating your own organic fertilizer from leaves, grass clippings, kitchen scraps and yard debris recycles waste into valuable, no-cost fertilizer. Natural fertilizers are less likely to burn tender, young plants as they are less concentrated than chemical formulas. You may also want the peace of mind of knowing the food you cultivate is free of noxious chemicals. Natural fertilizers are chemical-free and can save you money.
Disadvantages of Natural Fertilizers
Natural fertilizers are slow to break down into the nutrients the growing garden requires. Many natural fertilizers, such as manure, seaweed or fish oil, are quite smelly and are too offensive to use on indoor plants. Gathering natural materials, such as seaweed, grass clippings and leaves, to add to the compost pile is labor-intensive and time-consuming. Distribution of nutrients in organic fertilizer varies. Organic materials break down at different rates, so the composition and content of organic fertilizer is never consistent. It is a misconception to believe that just because a fertilizer is organic, it is automatically safer. Organic fertilizer, if you apply it incorrectly, can contribute to surface and groundwater contamination, create a nutritional imbalance in the soil and cause salt burns.
1. Not All Products Are Created Equally
Not all products are created equally and many organic products produce inconsistent results. Make sure you are selecting a product that is industry vetted by reviewing any university studies or case studies.
2. Nutrient Levels Are Low
The level of nutrients present in organic fertilizer is often low. In addition, the nutrients are usually complexed in organic chemical structure; this means using organic fertilizer may not produce the pop of color seen with a chemical fertilizer. Using an organic fertilizer is a process, not an event.
3. DIY Compost is a Complicated Procedure
While you can produce your own compost, it’s a messy and complicated process that often leads to an inconsistent product and
