The presentation by Proshanta Roy covers the topic of Triple Super Phosphate (TSP), detailing its composition, manufacturing process, advantages, disadvantages, and future prospects. TSP, a water-soluble phosphate fertilizer, is essential for enhancing root growth and crop yields, though it faces challenges like short reaction times and storage issues. The future of TSP includes developing higher analysis fertilizers to support agriculture in developing countries.

5. WHAT IS TSP FERTILIZER ?
 Chemical molecular formula is Ca(H2PO4)2.
 Superphosphate containing 44 to 51% of
available P2O5
It is more water soluble phosphate fertilizer.

10. ADVANTAGES OF TSP
Lower costly
Growth of the root system.
 Requires small capital investment and low skilled
manpower.
Influence the negative side for nitrogen fertilizer.

11. DISADVANTAGES OF TSP
Short reaction time.
Deteriorates storage bags.
It is not suitable for blending with urea.

12. FUTURE OF TSP
To make high analysis TSP fertilizers for hundred years –
on world wide basis
 TSP fertilizers cost increase
High cost high analysis to promote developing countries
from lower grade TSP

13. SUMMARIZING FOR TSP
TSP play an important role in increasing crop yields.
It uses if plants are small and producing little or no flower.
Weak roots converted into strong roots.
 Flows quicker than other fertilizer.
