Pressurized Hot Water and DTPA-Sorbitol, Viable Alternatives for Soil Boron Extraction
Pressurized hot water and DTPA-Sorbitol are two relatively new soil boron (B) extraction methods with potential to replace the cumbersome hot water extraction. The objective of this research is to produce data in support of acceptance or rejection of these two alternative B extractions. The three …

Pressurized Hot Water: An Alternative Method of Nutrient Extraction and Subsequent Analysis for Use in Small-Scale Agriculture
… have economical and environmental benefits. The pressurized hot-water (PHW) extraction coupled with colorimetric or turbidimetric analyses shows promise as an alternative to current procedures. Accepted methods of colorimetric analysis for NO3-N and P exist but an alternative method to atomic …

Predicting Maize Yield, Nutrient Concentration and Uptake in P and K Fertilized Soils: Pressurized Hot Water and Other Alternatives to Mehlich I Extraction in Guatemala Soils
… untested [Bray 1, Mehlich III, Olsen and pressurized hot water (PHW)]. Pressurized hot water is relatively simple and inexpensive, but is not yet tested against other extraction methods under variable P or potassium (K) fertilization levels. To determine whether PHW-extracted nutrients …

On-line screening of bioactive compounds and application of comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry for the analysis of birch bark
… from birch bark using an environmental friendly pressurized hot water extraction technique. It provided good extraction efficiencies for phenolic compounds compared to those achieved with Soxhlet extraction. With pressurized hot water extraction the amount of extractable phenolic compounds …

Wood extractives in hemicellulose stabilized emulsions
… from thermomechanical pulping (TMP), by pressurized hot-water extraction (PHWE) or by mild alkali pressurized hot-water extraction (BLN). The isolates were either used as such (Con), after spray-drying (Spdr) or after ethanol precipitation (EtOH). The content and composition of phenolic …
