Azolla Biofertilizer Is an Effective Replacement for Urea Fertilizer in Vegetable Crops
نویسندگان
چکیده
Azolla spp. is a water fern that hosts Anabaena azolla, an N-fixing cyanobacterium, in its dorsal leaf cavities. occurs naturally freshwater bodies warm-temperate and tropical regions, they have commonly been grown rice paddies as living fertilizer, providing N to the crop. We evaluated potential use of harvested from applied biofertilizer dryland vegetable crops. Two-thirds greenhouse gas emissions crop production attributed including fossil fuels used fertilizer transportation. on-farm ponds could remove CO2 atmosphere minimize transport. A 140-d laboratory incubation was compare mineralization with compost cyanobacterial treatments. treatments had greatest availability at end (73.0%), demonstrating least (15.5%), biofertilizers moderate release (31.6%). study uptake yield kale (Brassica oleracea) receiving compared urea organic fertilizers. The nitrogen by followed same pattern study, highest among fertilizers, overall. Compost yielded better than control but lowest yielding Finally, we agronomic effect manure rates spinach (Amaranthus cruentus) radish (Raphanus sativus) crops field on alluvial peat soils. Fertilizer affected both locations did not affect yield. treatment resulted yields (18–27 t ha−1), rate soil branch numbers. shows promise for crops; however, economic feasibility analysis needed prior encouraging widespread adoption use.

The feasibility for replacement of urea with nitrogen nano-chelated fertilizer in olive (Olea europaea L.) orchards
Nitrogen is an important element in the life of a plant. A wide range of nitrogen-containing compounds is available in the world market, with different formulations and efficiencies. Urea is present in most fertilizer applications; however, nano-nitrogen products are becoming popular although there is only limited information on their field efficiency. Thus, this paper studied the foliar applic...
