Chemical Name: Ammonium Molybdate
Molecular Formula :( NH4) 6Mo7O24 , 4H2O
Molecular Weight: 1235.86
Purity: 99%min ,Mo 54.0%min
Colorless or pale yellow-green diamond-shaped crystal, relative
density 2.498g/m3 (20°C). Stable in the air, its aqueous solution
is weakly acidic, the solubility in the aqueous solution of 20° C
and 80-90°C, respectively, equal to 300 g / l and 500 g / l. Heated
to 90°C, will loss a water of crystallization, 170 ~ 190°C, broken
down into ammonia, water, and molybdenum trioxide. Placed air
weathering, and lose some ammonia. Soluble in water, acid and
alkali, and insoluble in ethanol. Toxic, the maximum allowable
concentration in the air is 2mg/m3.
It can promote the absorption and conversion of a variety of
nutrients, improve crops carbohydrates and protein synthesis.
It can promote the growth and development of the nodule, Rhizobium
nitrogen fixation activity, the promotion of biological nitrogen
fixation and nodule more bulky.
It can make thick leaves of fruit trees, protecting flowers and
fruit, improve pollination and fruit set, fruit enlargement fast.
- Seed dressing: per kilogram seeds with 1-2 grams ammonium
molybdate. Spraying with stirring in order to ensure spray
uniformly after Dilution. Seeding after stacking 1-2 hours to be
- Seed soaking: Soaking the seeds 12-20 hours of seed with 0.05%
ammonium molybdate solution. treatment and spraying the
combination, you can save fertilizer. The seed treatment and foliar
spray by combining can save fertilizer.
- Foliar spraying: 0.03-0.05% ammonium molybdate solution for 50-75
kg / acre, in the seedling stage or before the flowering stage
continuous spraying 2-3 times can get the best results, each
separated by 7 to 10 days.
- Seed fertilization: per acre with 10-28 gram ammonium molybdate of
water dissolved mixed with phosphate, potash in the furrow or hole.
Packing:25kgs plastic woven bag.
Stored in a cool, dry warehouse to prevent the hot and humid. Don’t
use iron containers to prevent the precipitation of molybdenum
fertilizer. It is best to operation with a pot or plastic film.
