Depth

Lawn: 10-15 cm। Vegetables: 20-30 cm। Root crops: 40-60 cm। 100 sq m lawn at 10 cm: 10 m³। Garden soil: ₹500-1,500/ton। Vermicompost: ₹8-15/kg — Indian organic farming staple।

Kitchen Garden

Terrace/balcony gardening booming in Indian cities। Grow bags (₹50-200): space-efficient। Cocopeat + vermicompost + red soil = perfect mix।

⚡ CalcWolf Insight

New topsoil settles 10-15% in the first season as it compacts under its own weight and rainfall. Over-fill raised beds and garden areas by 2 inches to compensate. After settling, top off with compost in year two.
