Black DAP™

Highly effective BLACK DAP™ is the future of affordable, productive farming!

 

The patented bio-coating offers a greater extent of proven agronomic benefits that ordinary NPK based fertilisers do not.

Phosphorus Tie Up

Phosphorous-deficient soils contribute substantially to the fact that farmers

lose as much as 70% of the phosphate fertiliser they apply to the environment.

 

Truth is, phosphorous-use efficiency in the year fertiliser is applied is generally less than 30%.

Studies show it can be as low as 5%.

Sustained Release of Phosphorus

  • BLACK DAP™ ensures that plants have a sustainable source of energy.

  • The patented carbon coating avoids phosphate tie-up.

  • BLACK DAP™ can be safely applied pre-plant, planting or top dressed for MAXIMUM performance.

  • Field trials have demonstrated that BLACK DAP™ is 25% more efficient than ordinary DAP.

High Energy Packet

Black DAP™ should be viewed as containing an extremely high energy packet that bonds with the nutrient to form an organic complex.

 

Independent research has shown that this forms a more stable complex than the original materials.

The Coating

The patented coating Launch® contains carbon organic-catalysts, organic acids, plant extracts, non-ionic surfactants, bio-stimulants and other proprietary ingredients that provide a  very high nutrient exchange capacity around the fertiliser granule and serve soil microorganisms an extremely high energy packet.

BLACK™ Enhanced Efficiency Fertiliser - Commercial Field Demonstrations

 

Phosphorus: a definite and strong trend of increased yield where Black DAP is used in replacement of un-coated DAP. A yield increase occurred across all farms, in all replications, at all application rates.


Improvements in yield varied from 8.5% to 12% amongst different N rates, over the total trial treatment area, average yield increased almost 10% where Black DAP was used.

 

Nitrogen: the broad trend across the trial showed Black Urea consistently out yields un-coated urea
across all application rates and even at significantly lower application rates. The superior results came with the lowest of the Black Urea rates, with Black DAP, though only when averaged over the three sites.

​

  • At Chiweshe the treatment of Black Urea (220kg/ha) with Black DAP (145kgs/ha) produced the best economic result with fertiliser N+P Cost per ha of $29 per tonne of grain produced.

  • Musana’s best result was a treatment of Black Urea (270kgs/ha) with Black DAP (145kgs/ha) which produced a tonne of grain with $49/ha of fertiliser.

  • Zvimba produced a tonne of grain with $46/ha worth of fertiliser with the Black Urea (220kgs/ha) and un-coated DAP (145kgs/ha).

  • By comparison, the usual practice of un-coated Urea (420kgs/ha) produced a tonne of grain at Chiweshe ($38/ha), Musana ($80/ha), Zvimba ($74/ha).


A new fertiliser program across the three farms would reduce (-35.4%) fertiliser input costs by $68/ha/t (per hectare and per tonne of grain produced) and increase average yield production to 6.62t/ha from 5.70t/ha (+16.1%).

​

Note: The lower application rates yielded the same or similar as higher rates suggesting a strong indication that the usual application rates are probably too high in the first instance.
