Tata Steel Introduces Hydroseeding to Restore Mining Slopes in Jharkhand

Hydroseeding Latest News

Recently, Tata Steel has introduced hydroseeding technology at its West Bokaro Division in Jharkhand.

About Hydroseeding

• It is a modern technique for sowing seeds by spraying a slurry mixture of seeds, water, fertilizers, mulch, and soil stabilizers onto the soil surface using specialized equipment.
• It aims to stabilise dump slopes, prevent soil erosion and accelerate green restoration through modern technology.
• It ensures uniform seed distribution, improved seed-to-soil contact, and better moisture retention, which enhances germination and early plant establishment.
• Process of Hydroseeding

• • Preparing Slurry: It involves preparing slurry made up of seed, mulch, fertiliser and water. This mixture is loaded into a hydroseeder.
  • The slurry is then sprayed onto the prepared soil surface using a hose or cannon.
  • Equipment and Technology: It is carried out using purpose-built hydroseeders available in a range of tank sizes and output capacities to suit different project scales.
  • These machines are designed to properly mix fibre mulch, seed and additives while delivering an even, controlled spray pattern.
  • The machine can spray up to 50 metres and cover dump slopes up to 80 metres.
• Applications: It is widely used for lawn development, slope stabilization, erosion control, and ecological restoration in difficult or uneven terrains.
• Advantages
  • Compared to traditional seeding methods, it is faster, cost-effective, and suitable for large areas.
  • It is especially useful on mine overburden dumps and rugged terrain where conventional plantation is difficult and time-consuming.
  • It controls erosion on open slopes, strengthens slopes, reduces landslide risks, promotes faster plant growth and natural greenery, retains soil moisture for germination.
