This is a list of prices of chemical elements.Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison.
Chambal Fertilisers and Chemicals Ltd (CFCL) is an Indian agrochemicals manufacturing company based in Kota in Rajasthan.Established in the year 1985 by KK Birla Group, Chambal Fertilisers is the largest manufacturer of Urea in the private sector with an installed capacity of 1.5 million tonnes per annum.
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]
It was found that the treatment of plants with Kelpak® and the bacteria, Pseudomonas fluorescens and Bacillus licheniformis, decreased plant stress responses and increased production. [72] The most recently mentioned study provides implications for crop benefits when the application of seaweed fertilizer to soils favors the growth of PGPR.
Urea is the most used fertilizer in the world, due to its high content of nitrogen, low cost and high reactivity towards water. [32] When exposed to ocean waters, urea is metabolized by phytoplankton via urease enzymes to produce ammonia. [33] + +
Organic nutrients increase the abundance of soil organisms by providing organic matter and micronutrients for organismal relationships such as fungal mycorrhiza, [47] (which aid plants in absorbing nutrients), and can drastically reduce external inputs of pesticides, energy and fertilizer, at the cost of decreased yield.
The fully integrated fertiliser plant in Sungai Liang will produce 3,900 tons of urea and 2,200 tons of ammonia per day once it is finished in 2021, helping to meet the growing global demand for food crops. [10]
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°.
