This webpage describes findings from the Soil Cooperative Research Centre (CRC) project investigating how organic amendments such as earthworm casting liquid (EL) and pyroligneous acid (PA) can improve nutrient use efficiency and phosphorus (P) availability in Australian cropping soils. The research team, lead by Dr Choppala, examined 3 contrasting soil types (red sandy loam, red clay loam and grey clay from Condobolin NSW) using FT-IR spectroscopy and P fractionation analysis. Results for these soils show that both amendments appear to improve P availability in the selected soils and identifies the chemical pathways involved. The findings suggest that organic amendments can enhance P availability in nutrient-deficient soils and limit P losses in fertile soils through complex soil-amendment interactions. While this research was conducted on NSW soils, the results are relevant across Australia.#
This is a carefully curated database of important soil resources. The data base is not exhaustive but rather a library of the resources we believe are the most useful for the audience. Each resource has been added after careful consideration against our selection criteria, including but not limited to its scientific validity, accessibility, and readability. The library generally does not include most academic research papers but may include some open-source papers written in accessible English.
