Slow release coating remedy for nitrogen loss from

Unfortunately the practical use of conventional urea is not so efficient which results in excessive nitrogen loss from the soil The potential hazards and other factors related to environment pollution have imposed some limitations on the use of urea for nutrients supply to the plants In past studies it is approximated that 20 to 70% of the conventional urea utilized at the fields escapes

Experimental studies addressing the longevity of Bacillus

The ability to form endospores allows certain Gram-positive bacteria (e g Bacillus subtilis) to challenge the limits of microbial resistance and survival Thus B subtilis is able to tolerate many environmental extremes by transitioning into a dormant state as spores allowing survival under otherwise unfavorable conditions Despite thorough study of spore resistance to external stresses
