Reduced disease severity was noted at 10 and 20 days post-inoculation in comparison to control plants, and the seaweed treatment was found to be more effective at reducing disease pathology than salicylic acid, a known plant protector from biotic and abiotic stresses. [79]

An agreement for a joint venture company "Ramagundam Fertilizers And Chemicals Limited" has been signed on 14 January 2015 between National Fertilizers Limited, Engineers India Limited (EIL) and FCIL for setting up new ammonia and urea plants of 2200 MT per day and 3850 MT per day capacity respectively at the existing site of Ramagundam ...
A maize crop yielding 6–9 tonnes of grain per hectare (2.5 acres) requires 31–50 kilograms (68–110 lb) of phosphate fertilizer to be applied; soybean crops require about half, 20–25 kg per hectare. [21] Yara International is the world's largest producer of nitrogen-based fertilizers. [22]
Adding urea to the ocean can cause phytoplankton blooms that serve as a food source for zooplankton and in turn feed for fish. This may increase fish catches. [ 54 ] However, if cyanobacteria and dinoflagellates dominate phytoplankton assemblages that are considered poor quality food for fish then the increase in fish quantity may not be large ...
In the U.K., fertilizer labeling regulations allow for reporting the elemental mass fractions of phosphorus and potassium.The regulations stipulate that this should be done in parentheses after the standard N-P-K values, as in "15-30-15 (15-13-13)".
The structure of the molecule of urea is O=C(−NH 2) 2.The urea molecule is planar when in a solid crystal because of sp 2 hybridization of the N orbitals. [8] [9] It is non-planar with C 2 symmetry when in the gas phase [10] or in aqueous solution, [9] with C–N–H and H–N–H bond angles that are intermediate between the trigonal planar angle of 120° and the tetrahedral angle of 109.5°.
