Fertilizers might appear complex at first, but different steps and chemicals go into their manufacture and application. The YouTube video “How Does Fertilizer Work” looks into the makeup and application of fertilizers.
Two kinds of nutrients are available via fertilizers: macronutrients and micronutrients. Plants require high amounts of the former and low amounts of the latter for proper growth.
Examples of macronutrients include sodium, potassium, and phosphorus. Examples of micronutrients include iron, molybdenum, and manganese.
Fertilizers can be grouped into two groups: straight fertilizers, which offer only one nutrient, and mixed fertilizers, which show the three primary macronutrients (i.e. NPK). Most fertilizers come in bags that spot a fertilizer ratio. This ratio is printed on the bags and usually consists of three numbers and a fourth in brackets. Each number in the ratio represents the specific concentration of nitrogen, phosphorus, and potassium. The number in the bracket represents the total nutrient offered per 1kg of fertilizer.
Deciding which fertilizer is the right fit for your plantation depends on the specific needs of your plants. Whatever you decide on, ensure that your fertilizer application is deliberate to obtain desired results.
