Jamshedji Tata founded Tata Iron and Steel Company in 1907 at Sakchi (now Jamshedpur), Jharkhand. He initiated prospecting and capital raising after iron ore deposits were identified in 1903. Though Jamshedji died in 1904, his son Dorabji Tata carried forward the project. The company began pig iron production in 1911 and steel production in 1912. By 1939, TISCO was the largest steel plant within the British Empire.

Chiria mine is India’s largest iron ore mine with 2 billion tonnes of reserves, operated by Steel Authority of India Limited (SAIL). These mines are part of the Singhbhum-Keonjhar-Bonai Iron Ore Belt, known for major iron ore deposits. West Singhbhum district is the richest source of iron ore in India and a key mining area in Jharkhand.

Notes:
Saranda Forest in Jharkhand is Asia’s largest Sal forest, consisting of Shorea robusta and Madhuca indica trees. It provides habitat for wildlife such as elephants and tigers. Jharkhand is called the “land of forests” with diverse terrains including hills and plateaus. Other biodiversity areas include Pithoria Valley and Netarhat Hills within the state. Saranda Forest is recognized for its extensive biodiversity and ecological significance in the region.

Notes:
Jharkhand’s total geographical area is approximately 79.70 lakh hectares (7.97 million hectares). Official sources, including the Chief Minister’s site and Maps of India, confirm the area as about 79,700 square kilometers, which equals 7.97 million hectares. NABARD data also verify this figure as 79.714 lakh hectares. Other options such as 10.2 million, 9.8 million, and 8.4 million hectares exceed the actual area by significant margins. Thus, 7.9 million hectares is the closest accurate measurement.

Notes:
Chandil Dam is built on the Swarna Rekha River in Seraikela Kharsawan district, Jharkhand. The dam is part of the Subarnarekha Multipurpose Project and has been functional since 1993. It serves irrigation, power generation, and water supply purposes. The dam is 56.5 meters high and 720 meters long. Barakar, Konar, and Gumani rivers are not associated with Chandil Dam.

Notes:
Laterite soil in Jharkhand occurs in Palamau, Gumla, and Singhbhum regions. It is acidic and low in fertility. The soil is rich in iron and aluminum oxides. Laterite soil requires heavy soil amendments for agriculture. Alluvial soil in Jharkhand is highly fertile for crops like rice, wheat, and sugarcane. Red soil is commonly found and supports crops with proper nutrient management. Smooth soil generally refers to fertile alluvial or sandy soils manageable with irrigation.

Notes:
The northern part of Jharkhand, including Koderma and Hazaribagh, is part of the Bihar Mica Belt containing mica deposits in metamorphic rocks. These rocks consist predominantly of mica schist with minerals like muscovite, quartz, feldspar, beryl, and tourmaline. Koderma holds the world’s largest mica reserve with high-quality ruby mica. This region differs from areas known for coal (Dhanbad), iron ore (Singhbhum), or diamond deposits found elsewhere.
