It is important to remember that when phosphorus fertilizer application is performed, using fertilizers as triple superphosphate
, phosphorus is not the only nutrient which is added, but other nutrients which are contained in superphosphate, such as calcium (Ca), because this fertilizer presents 12% CaO.

Reducing ammonia loss from urea and improving soil-exchange ammonium retention through mixing triple superphosphate
humic acid and zeolite.
However, the mutual reaction showed that the planting in 1st July with the consumption of 125 kg triple superphosphate
, the planting in 10th July with the consumption of 225 kg/hec, the planting in 20th July with the consumption of 125, 175 and 225 kg/hec of triple super phosphate lead to generate the maximum number of seeds.
In P and K trials, the sources of N, P and K used were ammonium sulfate (20% N), triple superphosphate
(44% [P.sub.2][O.sub.5]) and potassium chloride (60% [K.sub.2]O), respectively.
T1, No addition of inorganic or organic fertiliser; T2, addition of triple superphosphate
(TSP) only; T3, addition of 90% TSP and 10% pig manure (PM); T4, addition of 80% TSP and 20% PM; T5, addition of 70% TSP and 30% PM; T6, addition of PM only.
For input treatments under HP (HP-FP, HP-Compost, HP-Mix), inorganic P fertiliser in the form of triple superphosphate
was applied to the plots before the commencement of vegetable cropping to raise the soil extractable P concentration to approximate those observed in the surface soil of vegetable farms in the Sydney area (~250mg/kg in the 0-0.10m layer (Chan et al.
Also purchase 0-20-0 (superphosphate), 0-44-0 (triple superphosphate
), or if you are an organic gardener, use raw rock phosphate.
will launch several projects of high technology between Damascus and Doha.He added that the company has made studies to establish some factories in Syria mot important of which is a factory for producing Triple superphosphate
fertilizer costing USD 600 millions.Minister Jouni said that the situation of industry in Syria is very good, pointing out that the growth rate of Industrial GDP has reached 15 % in addition to the growth of exports by 63 %.
Phosphate fertilizer was added as a single dose before planting when preparing the land in the form of triple superphosphate
(46% P2O5) (150 kg P2O5 / ha), while nitrogen fertilizer has been added as a dose of 100 kg N / ha in the form of urea fertilizer (46% N) after two weeks of planting.
