Molybdenum(VI) can be reduced to the +5 and +4 oxidation states quite readily, and so its biological role seems to be that of an electron 'sink' in redox processes. 0000046037 00000 n 0000001639 00000 n ?~�ݭ��|�H3�7@� ��>S endstream endobj 93 0 obj 227 endobj 52 0 obj << /Type /Page /Parent 49 0 R /Resources 53 0 R /Contents [ 60 0 R 62 0 R 64 0 R 66 0 R 68 0 R 70 0 R 82 0 R 84 0 R ] /MediaBox [ 0 0 595 842 ] /CropBox [ 0 0 595 842 ] /Rotate 0 >> endobj 53 0 obj << /ProcSet [ /PDF /Text ] /Font << /F1 57 0 R /F2 77 0 R /F3 71 0 R /F4 73 0 R /TT1 78 0 R /TT2 80 0 R >> /ExtGState << /GS2 88 0 R /GS3 87 0 R >> /ColorSpace << /Cs6 56 0 R /Cs8 54 0 R /Cs9 55 0 R >> >> endobj 54 0 obj [ /Separation /All 56 0 R 85 0 R ] endobj 55 0 obj [ /Separation /_Black_ 56 0 R 86 0 R ] endobj 56 0 obj [ /ICCBased 89 0 R ] endobj 57 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 89 /Widths [ 289 325 488 578 578 772 702 296 271 271 417 578 289 330 289 539 578 578 578 578 578 578 578 578 578 578 289 289 578 578 578 487 975 676 553 601 646 488 463 739 674 254 389 620 402 836 759 782 528 782 558 526 451 660 639 977 623 587 ] /Encoding /WinAnsiEncoding /BaseFont /Futura-Heavy /FontDescriptor 58 0 R >> endobj 58 0 obj << /Type /FontDescriptor /Ascent 848 /CapHeight 754 /Descent -262 /Flags 262176 /FontBBox [ -148 -264 1178 1002 ] /FontName /Futura-Heavy /ItalicAngle 0 /StemV 140 /XHeight 491 /StemH 128 >> endobj 59 0 obj 4318 endobj 60 0 obj << /Filter /FlateDecode /Length 59 0 R >> stream ROLE OF MOLYBDENUM IN THE BIOLOGICAL FUNCTION 301 58.6% is observed in plants treated with sodium tungstate on exposure to same concentration of sulfur dioxide. Deficiencies of 20 to 24 elements in animals and man (Frieden, 1972) and of 13 to 18 elements in plants (Epstein, 1965) have been recognized.

It is involved in several different processes, including photosynthesis, which nearly all living organisms are dependent on. Soil and plant tissue tests have been developed to assess the nutrient content of both the soil and plants. Role of Molybdenum in Horticultural crops Molybdenum is a trace element found in the soil and is required for growth of most biological organism including plants (0.1-2.0 mg kg-1 plant dry matter) and animals.

Molybdenum (Mo), an essential trace element required for nitrogen fixation and the reduction of nitrate to nitrite in plants and bacteria, is widely distributed in nature.214Geochemical surveys in England found that Mo content in soil and sediment corresponds closely to underlying black shales.215Other sources of Mo in the environment include industrial contamination by metal alloy … Molybdenum (Mo) is present as a pterin-cofactor in the active center of plant enzymes catalyzing key steps of nitrogen, carbon, and sulfur metabolisms, making them essential for efficient growth under the diverse environmental conditions. By analyzing this information, plant scientists can de-termine the nutrient need of a given plant in a given soil. fulfilled 70% of the demand in Malaysia [2]. 0000032563 00000 n 0000012307 00000 n A majority of soils contain some levels of copper in one form or another, however, often times the amounts of copper that are naturally occurring in the soils are not enough for the plant to be […] Jun-Ichi I, Nonomura KI, Ikeda Yamaki S, Inukai Y, Pollard AS, Parr AJ, Loughman BC (1977) Boron in, Baker AS, Cook RL (1959) Green house stud.
