What is the difference between organic and inorganic fertilisers?

Organic fertilisers are derived from living organisms, while inorganic fertilisers are synthetically produced using chemicals.

Organic fertilisers are made from natural, living sources such as plants, animals, or composted waste. They are typically rich in a variety of nutrients, including nitrogen, phosphorus, and potassium, which are essential for plant growth. Organic fertilisers release these nutrients slowly over time, as they are broken down by soil organisms. This slow release provides a steady supply of nutrients to plants, promoting healthy growth without the risk of nutrient burn. Organic fertilisers also improve the structure of the soil, increasing its ability to hold water and nutrients, and promoting the growth of beneficial soil organisms.

Inorganic fertilisers, on the other hand, are synthetically produced using chemicals. They are typically formulated to provide specific ratios of nutrients, which can be tailored to the needs of particular plants or crops. Inorganic fertilisers are fast-acting, providing a quick boost of nutrients to plants. However, they do not improve the structure of the soil or promote the growth of beneficial soil organisms. In fact, overuse of inorganic fertilisers can lead to nutrient imbalances in the soil, and can cause harm to the environment through runoff into waterways.

In summary, while both organic and inorganic fertilisers provide essential nutrients for plant growth, they differ in their sources, their effects on the soil, and their environmental impacts. Organic fertilisers are derived from natural, living sources and improve the health of the soil, while inorganic fertilisers are synthetically produced and can cause environmental harm if overused.
