In news A former naval officer who is an expert in soil-less agriculture has been carrying out campaign, ‘Mission Turmeric 2021’
- It aims to begin an “orange revolution” by teaching people to cultivate turmeric in shade houses in grow bags (large porous containers made of high density polyethylene) packed with coco-peat (made from the pith of the coconut husk) instead of soil.
- The method resulted in better yield with higher Curcumin content.
- Curcumin is a bright yellow phenolic compound in Turmeric known for its potential to fight cancer.
What is soil-less agriculture?
- In soil-less agriculture, such as hydroponics, micro and macro nutrients that have been pre-mixed into a water reservoir, along with high levels of oxygen, are delivered efficiently to the plant roots.
- Advantages of Soilless Agriculture
- Faster growth
- Extreme decrease in water and nutrient use
- Controlled Environment Agriculture (CEA): CEA is a method of agriculture that optimizes the temperature, humidity, airflow, and light within the growing environment of a farm.
- Location: The farm is closer to the consumer, decreasing the carbon footprint of delivery and increasing the freshness of the product.
- Requires less space to grow
- Soil-less agriculture cannot be treated as a magic solution. Besides the high initial investment, the method requires practice in order to succeed.
- Growers need to manage the various parameters more meticulously as compared to soil-based cultivation.
- And despite the good results, there is no premium pricing for the produce from hydroponics
