What are biofertilizers? Give two examples. |
|
Answer» Any fertilizers involving living organisms, or the products obtained from living organismscan be REFERRED to as biofertilizer, although nowadays, the term isgenerally used for living organisms usedfor fertilizer purpose.Various micro-organisms are present in soil and they play an important role in helping plants to grow.A handful of soil has several milions of bacteria - mostly saprophytic - converting organic wastes in soil into soluble sources of nutrients for plants. Their activity also makes nutrients in soil available - solubilization of phosphates for example. Enzymes released by fungi such as MYCORRHIZAE can convert rock phosphates into soluble phosphates. Some microbes makeit DIFFICULT for pathogenic micro-organisms to affect plants.The most important nutrient for plants - Nitrogen - is “fixed” ie,converted from gaseous form to soluble form such as ammoniacal radical by various “nitrogen-fixing” bacteria. Someof these are independent. others are symbionts. If the population of such microbes in soil is high, the nitrogen requirement of a plant crop can be signiifcantly met by their activity.Scientists have identified a variety of such micro-organsims that provide some important input to plants.Use of biofertilizers isbenefical for a varietyof reaosns - they are ECONOMICAL, and also ecologically sustainable.Hence steps to promote their use in agriculture are indeedimportant.Only as a sample - certainly not an exhaustive list - here are a few mico-organisms that can be called biofertilizers.Various cyanobacteria -Nostoc, Anabaena.- some are free-living, others are symbionts.Rhizobiumspp - can live freely, but can do significant quantities of N-fixation when they form root knot nodules with their specific host leguminous plants.Mycorrhizae -Glomusfasciculatus.Azotobacter- free livingN-fixation. |

A short note in point on chrysophytes |
|
Answer» Chrysophytes, or GOLDEN algae, are common microscopic chromists in fresh water. Some species are colorless, but the vast majority are photosynthetic. As such, they are particularly IMPORTANT in lakes, where they may be the primary source of food for zooplankton. They are not considered truly autotrophic by some biologists because nearly all chrysophytes become facultatively heterotrophic in the absence of adequate light, or in the PRESENCE of plentiful dissolved food. When this occurs, the chrysoplast atrophies and the ALGA may turn predator, feeding on bacteria or diatoms. |
