It’s a granular, water-soluble substance that dissolves quickly in soil, releasing phosphate and ammonium for plant uptake. DAP is a popular choice for farmers due to its high phosphorus content, which is crucial for root development and overall plant growth.
- DAP is a concentrated phosphate fertilizer containing approximately 18% nitrogen and 46% phosphorus (P2O5).
- Besides its primary use as a fertilizer, DAP has various industrial applications, including fire retardant properties, metal finishing, and as a fermentation aid.

- National Chambal Sanctuary, also called the National Chambal Gharial Wildlife Sanctuary, is a 5,400 sq. km tri-state protected area in northern India home to critically endangered gharial (small crocodiles), the red-crowned roof turtle and the endangered Ganges river dolphin. Located on the Chambal River near the tri-point of Rajasthan, Madhya Pradesh and Uttar Pradesh, it was first declared as a PAs in Madhya Pradesh in 1978 and now constitutes a long narrow eco-reserve co-administered by the three states. Within the sanctuary the pristine Chambal River cuts through mazes of ravines and hills with many sandy beaches along its banks.
- Deep within the subcontinent lies a land whose many secrets lie still hidden from the human eye in its still largely unexplored terrain. A land is synonymous with harsh terrains and its breathtaking beauty, Chambal. Now uncover the many secrets of the famed land at the Chambal National Sanctuary. Originating in the Vindhyan ranges in M. P. The Chambal River snakes its way through the states of M. P. Rajasthan and U. P. before finally meeting the Yamuna in the Etawah district of U. P. Its rich bio-diversity ensured that it was declared a National Sanctuary in 1979 with its total area spanning across the three states of M. P. Rajasthan & U. P. The last bastion for some of the country’s most endangered wildlife like the Gharial, Mugger, Turtles, Otter and the fresh water Dolphin, the Chambal region also boasts of a wide variety of aquatic and terrestrial birds.
- After rampant poaching and fishing almost wiped out the Gharial population from the country in the 70’s, a captive breeding and reintroduction programme was started. Chambal was chosen as one of the main areas for reintroduction of the species back into the wild. The Chambal Sanctuary in U. P. covers an area of 635 sq. kms.
- Spread over the Agra and Etawah districts, and a total of 290 different species of migratory and resident birds have been identified in the region so far. Winter is the best time to visit the sanctuary. A boat ride in its tranquil waters during this time is an exhilarating experience with spectacular sightings of the big reptiles basking along the 180kms. Sparkling sand stretches in the morning sun. but the main draw of the sanctuary are of course the Flamingos that arrive here in November and stay till May. The Rudy Shelduck also arrives a little earlier in September & stays here till May. The Indian Skimmers have Huge Colonies in the sanctuary and breed prolifically here.

How many statements is or are correct?
A. Only one
B. Only two
C. All three
D. None of the above
Solution & Detailed Explanation
Answer: (C) All three
Detailed Explanation
- Core Concern: Food safety in Indian agriculture is a vital but often neglected issue. Contamination risks are present at every stage—from farm to fork. These include pesticide residues, post-harvest fungal growth, bacterial contamination, and adulteration.
- Major Problems: Heavy pesticide usage (India ranks 4th globally) causes residue accumulation. Poor post-harvest infrastructure leads to aflatoxins and microbial spoilage. Rampant adulteration in milk, spices, and oils. Weak enforcement of the Food Safety and Standards Act (FSSAI).
- Export Rejections: Frequent bans by EU and US. Estimated loss: $15–20 billion annually.
- Seven years ago in July 2018, the Food Safety and Standards Authority of India (FSSAI) launched the Eat Right India initiative.
Eat Right India Complies with the following SDGs and Government Schemes
