Copy link Pepper Trial with Puraloop in Italy
LANDLAB Srl Società Benefit, Italy 2024
Key Conclusions
- Plants visibly responded to P fertilization as the plants with zero P supply stopped growing after 1 month.
- No significant yield differences were found between Puraloop and TSP, however Puraloop resulted in higher P uptake, which shows that it is as efficient as conventional P fertilizers.
Objective
To evaluate the performance of Puraloop as a source of phosphorus for pepper using a pot trial.

Product
Puraloop 0-38-0
Assessments
Yield (g fruit/plant), P uptake (mg/pot)
Treatments
For this trial, pepper was planted in a randomized block design (RBD) experiment set up with 6 blocks.
Each repetition consisted of 5 pots with a 3L volume. The treatments consisted of a negative control (zero P), TSP, and Puraloop. Both TSP and Puraloop treatments received 690 mg P2O5/pot.
Other nutrients were applied in sufficient amounts via fertigation.

Results
Yield per plant (g)
Both treatments with P fertilizers produced yields without significant difference (measured in grams of fruit per plant). Plants with zero P stopped growing after 1 month.
Yield in grams of fruit per plant
P uptake (mg)
Puraloop variant had a better P uptake which proves that this fertilizer is as efficient as the conventional triple superphosphate (TSP).
Uptake of phosphorus from each variant
Puraloop is a recycled phosphate fertilizer derived from organic waste streams and designed for sustainable food production. This trial on pepper (Capsicum annuum) showed it can deliver results comparable with other conventional sources of phosphorus.
