Copy link Maize Trial with Puraloop in Italy
LANDLAB Srl Società Benefit, Italy 2024
Key Conclusions
- Plants responded to P fertilization, with a significant difference between the –P and +P treatments.
- While the maize fertilized with TSP had a slightly higher dry biomass than the maize from the Puraloop treatment, the difference was not significant, indicating that Puraloop is as efficient as conventional TSP fertilizer.
Objective
To evaluate the performance of Puraloop as a source of phosphorus for maize using a pot trial.
Trial Details
Trial station
LANDLAB Srl Società Benefit, Italy
Crop
Maize
Product
Puraloop 0-38-0
Assessments
Biomass (g dry mass/pot), P uptake (mg/pot)
Treatments
For this trial, maize 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 460 mg P2O5/pot.
Other nutrients were applied in sufficient amounts via fertigation.

Results
Dry biomass (g)
Both treatments with P fertilizers produced a significantly higher amount of dry biomass (measured in grams per pot) compared to pots with zero P.
Dry biomass (g)
P uptake (mg)
The differences in P uptake between the variant fertilized with Puraloop and the variant fertilized with conventional triple superphosphate (TSP) were not significant.
P uptake (mg)
Puraloop is a recycled phosphate fertilizer derived from organic waste streams and designed for sustainable food production. This trial on maize (Zea mays) showed it can deliver similar results as other conventional sources of phosphorus.
