Definition - What does Fertilizer mean?
A fertilizer is a natural or synthetic, chemical-based substance that is used to enhance plant growth and fertility. Fertilizers may also enhance water retention and filter any excess liquid, hence enhancing soil effectiveness. Fertilizers typically offer the three major macronutrients potassium, phosphorus, and nitrogen. Fertilizers may also add secondary nutrients such as sulfur, magnesium, and calcium to the soil or growing media.
MaximumYield explains Fertilizer
There are different types of fertilizers that can be used on specific plants to promote their growth. For example, coffee grounds are commonly used for plants that thrive on acidic substances, such as azaleas, blueberries, roses, and tomatoes. When working with coffee grounds, it is important to water the soil afterwards to promote absorption.
Because they have a high percentage of calcium, eggshells are also used as fertilizing agents for produce like peppers and tomatoes. The calcium can help prevent rot while boosting the plant’s growth. Aged manure and compost are by far the most popular fertilizers used with just about any type of plant.
Depending on your plant, weeds can also be used as fertilizer. Chickweed, horsetail, burdock, yellow dock, comfrey, and nettles are often used because of their high nitrogen content.
