The weevils are an effective natural means of tackling Azolla
and are at their most active at this time of year.
captures and processes nitrogen from the air with the help of bacteria that live on it, and further study may let scientists engineer that trick into crop plants, reducing the need for fertilizer, she says.
The aquatic plants selected for phytoremediation viz Azolla
pinnata and Lemna minor were collected freshly from natural pond at Horticulture Research Station Ganesh Khind, Pune, and brought to the laboratory in plastic bags along with water.
Nitrogen fixing shrubs such as Sesbania, legumes, or Azolla
Anabaena (the water fern) may be used as off-season crops to accumulate nitrogen in soils for its eventual use by grain crops.
Megafossils are commonly spectacularly well preserved as compressions featuring colour patterns on insects' wings, exquisite whole flowers of Florissantia, and delicate ferns like the floating Azolla
