  1. What is the difference between organic fertilizers and chemical ones?

    Answer: Organic fertilizers, also referred to as the natural type are made by using dried organic matter like cow manure, earthworm castings, seed meal, crop remains, seaweed and compost. Chemical fertilizers on the other hand are chemical compounds which have been synthesized from a natural source, acquired from petroleum byproducts. They are often acidic and used to give plants its supply of potassium, nitrogen and phosphorous.

  2. What do the numbers in organic fertilizers mean?

If for example a product was listed with the numbers 7-11-5, this means the product has 7 percent nitrogen, 11 percent phosphorous and 5 percent potassium.

  3. What factors should I consider when choosing organic fertilizers?

    Answer: Firstly, determine the kind of soil you have to work with. There are three types of soil—loam, sandy and clay. The type of fertilizer you need will be based on the soil type you have. Next, consider the nutrients that the soil lacks. The most effective way to know this is through a standard soil test. Once tested, the data will show you the nutrient composition of your soil—go for a fertilizer with the nutrients that you soil does not contain. Choose whether you want dry or liquid fertilizer. Dry fertilizers are recommended for standard plant care and maintenance. They are also slow-release fertilizers. Liquid fertilizes meanwhile are fast-acting and give tired plants the lift it needs to get it back on track.
