Growing your garden organically is the latest trend. Most gardeners have realised the benefits of organic fertilisers in landscaping and gardening, and have adopted this approach in a big way. But before we look towards the benefits of organic fertilisers, let us first understand why we need to fertilise our gardens.
Why should we fertilise the soil?
Just like us humans, plants also need the nourishment to grow. The soil naturally contains all the important nutrients that plants need but as they get used up, the quality or fertility of the soil depletes. The plants no longer get the required nutrients and they slowly begin to deteriorate. This is where fertilisers come in – adding fertiliser to the soil replenishes its fertility which is great for your garden.
What kind of nutrients do the plants need for healthy growth? Basically they require three elements in larger quantities, namely Nitrogen, Potassium and Phosphorous along with calcium, iron, magnesium, sulfur, manganese and zinc. Chemical fertilisers which are manufactured products contain the three major elements, which are released into the soil along with trace elements of other nutrients. Chemical fertilisers release these minerals into the soil very quickly which may lead to an overdose, causing the plant roots to burn out. The soil should have a balanced mix of the essential nutrients required for growth.
What are organic fertilisers?
Organic fertilisers are plant and animal matter along with some minerals that are naturally present in soil. They are not processed and are present in their natural form. Organic fertilisers are as close to the natural form as possible allowing the plants to absorb them easily. Animal manure, green manure, organic matter, wood ash, bone meal, fish meal, cotton seed meal, etc. are some examples of organic fertilisers.
Benefits of organic fertilisers
Using organic fertilisers in your garden ensures that your plants grow healthy. Organic fertiliser improves the soil structure and also helps it retain more moisture. It also improves the drainage and gives a boost to the microbial activity in the soil that is so essential to the plant growth.
Organic fertilisers release the nutrients into the soil very slowly allowing plants to absorb them easily. As a result there is little chance of damage to the roots or the plant health. Composting is a great way to recycle kitchen scraps, dried leaves and plant matter into organic fertiliser which provides the best nutrients for the soil.
Since organic fertilisers take a longer time to break down, you might not see immediate results, but over a period of time your plants will grow healthy and robust.
