“…Coating thickness, of 1% polymer strength, was maintained as (single, double and triple) on fertilizer for lab and pot trials. Coated fertilizers were allowed to dry under laboratory conditions at 25°C and stored in polyethylene bags till the application as described by Yaseen et al (2017). Bulk amount of soil used for the lab and pot trials was collected from the field at Research Area of Institute of Soil and Environmental Sciences, University of Agriculture, Faisalabad, Pakistan.…”

Efficiency of conventionally applied nitrogen (N) fertilizers ranges from 35 to 45%. Poor efficiency due to prompt release of excess nitrogen in the soil also threats environment. The nitrogen fertilizers performance can be enhanced by controlling the release of nitrogen through encapsulation with polymer and synchronizing the nitrogen release with plant up-take pattern. To test this hypothesis series of experiments were conducted. Nitro-chalk (calcium ammonium nitrate) as test N fertilizer was used for polymer coating. Laboratory and pot experiments were conducted to determine the effective polymer thickness coated on nitro-chalk, and results revealed that two layers of polymer performed the best as consistent release of N significantly increased growth and yield attributes of wheat. Similarly, coated nitro-chalk also corresponded well to the nitrogen requirements of wheat plants in field. Consequently, polymer coated treatments significantly improved wheat grain yield by 10 to 17% compared with uncoated fertilizer at the same nitrogen application rate. Reducing the rate of application of polymer coated nitro-chalk by 25% produced more grain yield as compared with the application of recommended rate of commercial nitro-chalk. Therefore, the results suggested efficient release of nitrogen from coated nitro-chalk increased production and nitrogen use efficiency. Furthermore, a 25% less application of nitrogen as polymer coated nitro-chalk than recommended application rate of nitrogen can be an effective measure to save input cost as well as increase in grain yield.

“…Improved potato growth was observed with coated fertilizer products. In maize-wheat cropping system, polymer-coated DAP promotes crop growth, yields, as well as enhances P use efficiency of wheat in normal management conditions (Ali et al 2017;Yaseen et al 2017). Excessive dissolution of uncoated DAP could be the possible reason behind lower yield of wheat.…”

Polymer coating of water soluble fertilizers to curb excess solubilization of nutrients is well-acknowledged fact. Lack of information on phosphorus (P) release from controlled release nitrogen-phosphorus (NP) formulation and its impact on nutrient use indices has driven us to conduct this experiment. We developed NP formulations by reacting liquid ammonia and orthophosphoric acid in laboratory. Resulting NP formulations were characterized by solubility fractions, microscopy, spectroscopy, and X-ray diffraction. After coating with poly(vinyl alcohol) (PVA) and liquid paraffin (LP) at 2 and 3 w/w% concentration, P release kinetics and temperature sensitivity (Q 10) of the formulations were compared with diammonium phosphate (DAP) at 20 and 30°C temperature in a P-deficient soil for 120 h of incubation. Finally, nutrient use efficiency and relative efficiency indices were determined from a greenhouse experiment in potted soil to assess the effect of polymer-coated formulations and of DAP at two application rates in comparison with a non-P amended control. Laboratory synthesized NP formulations were alkaline in reaction, definite cubical to hexagonal crystalline structure with smooth surface generating peaks related to P and N in fingerprinting region of Fourier transform infrared spectroscopy. Polymer coating of NP formulations delayed the P release compared with DAP, while LP-coated formulations showing slower P release than PVA-based coatings. Despite LP-coated formulations showed greater temperature sensitivity (Q 10), the PVA-based formulation significantly increased yield and biomass accumulation of wheat, with concomitant increase in crop P uptake and P use efficiency. Both LP and PVA-coated formulations showed a significant residual P accumulation in post-harvest soils. The findings underline the potential of polymer coating technology for enhancing P use efficiencies, thereby reducing environmental P footprints.

“…One simple mechanism of EEF is slow‐ or control‐release materials (Nyborg et al, 1995; Yaseen et al, 2017). These materials typically have a coating of some type, such as a polymer, which provides slow or controlled release of the fertilizer.…”

The discovery and development of phosphorus (P) and P fertilizers provide context for current management conventions. Average crop yields were stagnant before the Green Revolution but have steadily increased since. This, along with conventional P management, has resulted in widely depleting soil P levels. Improved technology and management are needed to meet the increasing P demand. Modern hybrids and cultivars have different P demand and uptake patterns that require changes in conventional P fertilizer placement and timing. Phosphorus fertilizer recommendations based on soil analysis remains valid, but evidence suggests a need for recalibrating soil test P (STP) critical levels (the STP concentration at which a response to P fertilizer would not be expected) and P fertilizer rates to accommodate high‐yield scenarios. Considering higher P fertilizer rates as a single solution poses environmental challenges, highlighting the need for improved P use efficiency (PUE). Phosphorus fertilization approaches that have the potential to improve PUE and enable high yields include crop‐specific precision placement of P, informed timing of P fertilizers, and new enhanced efficiency sources of P fertilizer. This paper examines these management approaches from historical, production, and environmental perspectives in modern cropping systems. Core Ideas History of P fertilization illuminates traditional soil P management and needed changes. Recalibration of STP and P fertilizer recommendations are needed to match increasing yield and rates of P uptake. Environmental concerns and diminishing P supply necessitate improvement in P use efficiency. Placement and timing are improved through understanding of variable rooting patterns. Enhanced efficiency P fertilizers can be effective if applied correctly.
