DeltaLent Phosphate EnhancerPhosphate Bioavailability Synergist
Polyaspartic acid (PASP) at 60% that supports phosphate and micronutrient availability and helps crops take up more nutrients.
Available Formulations
DeltaLent Phosphate Enhancer is supplied as a liquid PASP solution at 60%. Other concentrations can be formulated to your requirements.
DeltaLent Phosphate Enhancer
A liquid polyaspartic acid (PASP) solution at 60% for phosphate fertilizers and phosphorus-containing NP and NPK blends. PASP is non-toxic and biodegradable, and its many carboxyl and amide groups bind nutrient ions, which helps reduce nutrient loss and supports uptake.

Agronomic Advantages
Engineered to maximize nutrient recovery and crop performance across diverse soil types.
Binds nutrient ions
Many free carboxyl and amide groups along the PASP chain give it a strong capacity to hold nutrient ions, reducing nutrient loss.
Supports nutrient uptake
PASP stimulates crop growth and nutrient uptake and strengthens stress resistance.
Higher yield in research
In a 15N tracer study by the Chinese Academy of Agricultural Sciences, urea enhanced with PASP raised wheat yield by 2.02 to 9.77% over conventional urea.
More nitrogen taken up
With high-molecular-weight PASP (>10 kDa), total nitrogen uptake rose 9.92%, fertilizer nitrogen uptake 4.65% and soil nitrogen uptake 19.62%.
Less nitrogen leaching
PASP kept more fertilizer nitrogen in the 30 to 60 cm soil layer and less in the 60 to 90 cm layer, reducing leaching.
Non-toxic and biodegradable
PASP is a non-toxic, biodegradable and environmentally friendly bioactive organic synergist.
Science & Mode of Action
How polyaspartic acid holds nutrients in the root zone and supports uptake.
Mode of Action: PASP Nutrient Retention
Polyaspartic acid carries numerous free carboxyl and amide groups that adsorb nutrient ions, so nutrients stay in the root-feeding zone longer and less is lost. Research published in Agronomy (2023) showed that urea enhanced with PASP increased wheat spike number, yield and nitrogen uptake, and that PASP of higher molecular weight gave the strongest improvement in yield and nitrogen-use efficiency.
