A young farmer from Kavalam in Alappuzha has developed a unique "Kizhi", or bundle farming, method that allows households to grow vegetables for up to five years using the same sack. Kalesh Kamal spent five years perfecting the technique, which is designed specifically for people living in flats or houses with limited space. By using small net bundles instead of traditional pots, residents can grow cauliflower, tomatoes, chillies and spinach on their terraces or in courtyards with minimal effort.

A five-year harvest from a simple sack

The most striking feature of Kamal's method is its longevity. Unlike traditional grow bags that often deteriorate, these bundles can be reused repeatedly for up to five years. The system stabilises the soil's pH levels, ensuring the growing medium remains fertile for multiple planting cycles. When one crop completes its life cycle, the farmer simply removes the old plant and inserts a new sapling into the same bundle.

This approach solves many common gardening problems. Bundle farming significantly reduces weed growth, as the enclosed net prevents unwanted seeds from taking root. It also offers protection against soil-borne diseases such as fungal infections and wilt, which frequently destroy tomato and chilli crops in Kerala. Because the bundles are lightweight and easy to handle, even children can participate in harvesting vegetables.

The secret soil mix and maintenance

The success of the "Kizhi" lies in a precise soil preparation method. Kamal uses three distinct types of soil: fine black soil, reddish soil with a higher grain content, and a sandy layer. To ensure the best quality, he sifts the soil using a simple net suspended from a tree, a cost-effective alternative to expensive industrial machinery.

The bundles are filled with a mixture that includes ten different organic powders, including neem cake for pest resistance. This nutrient-rich environment means families do not need to spend money on expensive external fertilisers or chemical boosters. To maintain the bundles, Kamal uses a small amount of specialised organic powder mixed with water every few years to keep the soil healthy.

The method has gained significant traction. Kamal now provides training to schools, teaching students how to produce their own food in small spaces. Even government officials are visiting to learn about the method. By avoiding chemical fertilisers, the system also protects essential earthworms in the soil, helping maintain a natural balance that is often lost in modern agriculture.
