What is Nano Urea?
State-owned National Fertilizers Limited (NFL) recently announced its entry into nano liquid urea production.
About Nano Urea:
- It is a nanotechnology-based revolutionary agri-input that provides nitrogen to plants.

Cicadas
Recently, for the first time in more than 200 years, two specific broods of the 13- and 17-year cicadas have emerged together in North America.
About Cicadas:
- Cicadas are hemipteran insects known for their loud, complex and species-specific acoustic signals or songs.
- The generic diversity of cicadas in India and Bangladesh ranks the highest in the world, followed by China.
- Habitat: Most cicadas are canopy dwellers and are found in natural forests with large trees.
- Types: Scientists divide the over 3,000 cicada species into two groups: annual and periodical.
- Annual cicadas: They emerge from the ground at different times each summer.
- They’re usually dark with greenish markings.
- These insects avoid predators by camouflaging themselves in the trees and flying from hungry birds and moles.
- Periodical cicadas: Only seven species of cicadas are in the periodical cicadas.
- These bugs all emerge from the ground at the same time(Summer).
- These groups appear after a dormant period of either 13 or 17 years.
- Ecological Significance: They prune mature trees, aerate the soil, and once they die, their bodies serve as an important source of nitrogen for growing trees.
