Am Biofertilizers Have An Edge Over Other Biofertilizers

This group of biofertilizers is the only among others having fungal system involved. Other biofertilizers exploit bacteria most commonly. Also this offers wide applicability with a wide range of plants having little selectivity, which is commonly reported in other biofertilizers. Though some exceptions exist with certain nonmycorrhizal families like chenopodiaceae, brassicaceae, and few nonhost plants of nyctaginaceae etc. The storage conditions also are very simple with no extra infrastructural requirements like low temperature and moisture content. Shelf-life is comparatively long. Bacterial systems have short life and cause cell death easily.

The hyphae of fungal system can extend much beyond (a few meters away) the depletion zone and thus can acquire nutrients from a much wider area. The fungal system also produces vegetative structures like chlamydospores and zygospores, which become dormant during periods of environmental stress and germinate with the return of favorable conditions. Thus, they are better equipped for combating unfavorable conditions and have longer shelf-lives compared to bacterial systems. These biofertilizer organisms are broad-spectrum and nonspecific. A single species is known to colonize approximately 90% of land plants. These biofertilizers have broad ecological adaptability and are known to occur in deserts as well as arctic, temperate, tropical, and other habitats. They offer a 25-50% reduction in phosphorus fertilizer application depending on the plant.
