There could hardly be a person to have forgotten the sight of significant tsunami waves that swept through the Indian Ocean in December 2004, killing nearly 2,50,000 humans in 14 one of a kind nations. It was indeed one of the deadliest natural disasters to have struck the world within the latest times. Affecting nearly 10,000 small and marginal farmers, tsunami waves destroyed over 24,000 acres of farmland within the Nagapatnam district of Tamil Nadu by myself. More than a decade has long past by using, and most of the victims nevertheless find themselves reeling beneath the havoc.
Not handiest had been the standing plants devastated, however the water from the ocean left the soil in a saline kingdom, rendering it mistaken for farming. Official inspection teams reported that restoring the soil should take about 10 years but farmers who have been reluctant in transferring to some other career sowed the seeds rarely a year later. To their dismay, not a unmarried seed germinated. In this hopeless situation, a few NGOs added them to Organic Farming as a savior of their uncultivable lands.
Organic Farming to the Rescue
To begin with, one needs to very well examine the soil circumstance, the quantity of salt penetration, amount and kind of salt, its sodium content material and alkalinity as they help in determining what measures are to be taken for soil revival. Studies inside the Nagapatnam district found out that salt had destroyed all of the natural remember and reached the depths.
If the salt had not infiltrated a good deal, it could have been eliminated through proper drainage strategies, but due to the fact that this was now not the case here, vast techniques had to be followed. Commencing with the elimination of sea dust deposits, NGOs helped the farmers enhance bunds and plow their fields. The trees uprooted with the aid of the waves were placed in deep trenches to let the soil breathe.
Depending on the nature and significance of penetration, appropriate salt-resistant crops were planted inside the district. Most commonly, a legume called Sesbania Bispinosa became sown as it’s far wealthy in nutrients and grows quickly. Legumes or every other salt-tolerant plants which includes barley, wheat, sugar beet and millet, may be grown in affected fields and plowed upon adulthood for loosening the soil and opening its pores.
The use of inexperienced manure (aka natural manure) is a verified technique for reviving salt-affected farms. In saline and sodic soils, this manure helps get better porosity and aids inside the launch of carbon dioxide and different natural acids at the time of composition. Organic manure additionally affords soil with many critical vitamins required for cultivating crops.
