Preplant Treatment of Block D9:
- 5 tons calcitic lime
- 3 tons gypsum
- Planted with saia black oats, June 2015
- Prepared and planted December 2015
- At the time of analysis, the cane was experiencing a drought and had not had rain for 4 months.
- Cane was analysed at 17 months before the 18 month ripener was applied for harvest at 24 months.
- The farmer does a once-off application i.e. no topdressing on either the chemical or ATLAS approach.
|Fertilizer||ATLAS 5:1:4 (21) Si Zn B||Chemical 4:3:4 (40) + Zn|
|Cost per ton||R5250.00||R8030.00|
|Fertilizer cost per ha||R6840.00||R6424.00|
Using industry recognised data capturing techniques, some key properties are reflected below.
|Tons/ha x RV ÷ 100||11.8||9.97|
|Less cost of Fert.||R6840.00||R6424.00|
End Difference = +R7822.75 /ha
20.36% increase in profit
It should be noted that the application of this fertilizer erases the need for a top-dressing yet it has the “legs” to carry a crop from planting to harvesting. This results in major savings in tractors, labour, compaction effects and crop variation.
The sustained release of nutrients allows the plant to access food when it wants it. Imagine its a hot and sunny week just before top dressing with a chemical program, the conditions are optimal for photosynthesis but nutrient levels are at their lowest. Nitrogen has leached and other elements are fixated in non-compatible forms. ATLAS increases the “nitrogen pool” in the soil through microbial stimulation. These microbes in turn exude organic acids which chelate cations making them available to the plant.
