How much phosphorus is in SSP?
SSP – A multi nutrient fertilizer containing phosphorus (14.5 %), Sulphur (11%) and Calcium (21 %).
SSP can apply as a basal fertilizer with other chemicals and organic fertilizers..
How do you use single super phosphate?
Directly at planting is the best time to use superphosphate. This is because it promotes root formation. It is also useful when plants are beginning to fruit, supplying nutrients to fuel larger fruit production. During this period, use the nutrient as a side dressing.
Is Super Phosphate acidic or basic?
But the degree to which they occur depends on the soil pH. Dicalcium phosphate predominates when the soil is alkaline, monocalcium phosphate when the soil is acidic, and phosphoric acid only when the soil is extremely acidic.
How do you fertilize SSP?
Single Superphosphate is produced by reacting naturally occurring phosphate rock with sulphuric acid. This process converts insoluble phosphates into forms more readily available to plants. Impact Fertilisers’ SSP manufacturing process uses blends of various rock phosphate rock sources.
What is super phosphate fertilizer?
Single superphosphate (SSP) was the first commercial mineral fertilizer, and it led to the development of the modern plant nutrient industry. This material was once the most commonly used fertilizer, but other phosphorus (P) fertilizers have largely replaced SSP because of its relatively low P content.
Is SSP water soluble?
Product Description. SSP contains 16% of Citrate soluble available P2O5, 14.5% Water soluble available P2O5, 11% of Sulphur, and essential micro nutrients in small proportions.
Is Super Phosphate harmful?
The superphosphate that was commonly used here for 60 years had high levels of the heavy metal, which can damage kidneys, bones and is a carcinogen. Hikurangi farmer Ben Smith said he stopped using superphosphate ten years ago – but it is a toxic legacy that is still giving.
Is super phosphate a chemical fertilizer?
Normal superphosphate or single superphosphate (NSP, SSP) is used solely as a fertilizer material. NSP can be used with most crops and is applied during the planting season. NSP is a solid phosphate fertilizer material that is produced from phosphate rock and sulfuric acid (H2SO4).
What is single superphosphate a mixture of?
Single superphosphate (a mixture of calcium sulfate and calcium phosphate)
When can you spread superphosphate?
With winter active clover-based pastures, it is customary to apply superphosphate in the autumn at the start of the main growing season. This is the best time to apply superphosphate where soil phosphorus levels are low and immediate responses are expected.
Does super phosphate lower pH?
– Of all the major fertilizer nutrients, nitrogen is the main nutrient affecting soil pH, and soils can become more acidic or more alkaline depending on the type of nitrogen fertilizer used. … Phosphoric acid is the most acidifying phosphorus fertilizer. – Potassium fertilizers have little or no effect on soil pH.
Do phosphates affect pH?
The addition of the phosphate to the soil suspension alters the pH, and the differences between the pH values of the suspensions are sufficient to account for the differences in phosphate retention.
