A fertilizer is a substance or mixture of substances that is used to improve or enrich the soil and provide the necessary nutrients for the growth and development of plants. Fertilizers contain essential nutrients such as nitrogen, phosphorous, and potassium, also known as macronutrients, which are needed in relatively large amounts. In addition to macronutrients, fertilizers may contain other essential nutrients such as calcium, magnesium, and sulfur, as well as trace elements such as iron, zinc, copper, and manganese, which are required in smaller amounts.

Fertilizers are applied to the soil or to plants in order to fill nutrient deficiencies and improve soil fertility. This can be done by adding liquid or granular fertilizers to the soil before planting or during plant growth. There are also slow-release fertilizers that provide nutrients gradually over time.

Proper use of fertilizers can help increase crop production, improve plant quality, and promote healthy growth. However, it is important to use fertilizers responsibly and following application recommendations, since excessive or inappropriate use can have negative impacts on the environment, such as water pollution and soil degradation.


There are several ways to prepare homemade fertilizers using common ingredients. Here are some homemade fertilizer ideas you can try:

  1. Banana Peel Fertilizer: Banana peels are rich in potassium, an essential nutrient for plant growth. To make this fertilizer, simply place banana peels in a jar, cover with water, and let sit for several days or even weeks. Then, dilute the mixture with water in a 1:5 ratio and water your plants with it.

  2. Coffee Fertilizer: Coffee grounds contain nitrogen, as well as other beneficial nutrients for plants. You can spread the coffee grounds directly on the soil around your plants or add them to your compost. You can also make a coffee infusion by diluting the grounds in water and use it to water your plants.

  3. Eggshell Fertilizer: Eggshells contain calcium, which is important for plant development. Wash and dry the eggshells, then grind them into a fine powder. Sprinkle this powder around your plants or add it to your compost.

  4. Weed fertilizer: Some weeds may contain valuable nutrients. You can make a weed tea by placing the weeds in a bowl of water and letting them steep for a few days. Then, dilute the mixture with water in a ratio of 1:10 and water your plants with it.
