Cover Crops and Soil Phosphorus Availability
Communications in Soil Science and Plant Analysis, 2017 Plants affect soil phosphorus (P) solubility through root exudates, but studies are lacking on species used as relay or cover crops in tropical environments.

Evaluating phosphorus availability in soils receiving organic amendment application using the Diffusive Gradients in Thin-films (DGT) technique [PDF]
, 2013 Phosphorus is a resource in finite supply. Use of organic amendments in agriculture can be a sustainable alternative to inorganic P, provided it can meet crop requirements.

A Global Database of Soil Plant Available Phosphorus
Scientific Data, 2023 AbstractSoil phosphorus drives food production that is needed to feed a growing global population. However, knowledge of plant available phosphorus stocks at a global scale is poor but needed to better match phosphorus fertiliser supply to crop demand. We collated, checked, converted, and filtered a database of c. 575,000 soil samples to c. 33,000 soil

Soil Microorganisms Mediating Phosphorus Availability Update on Microbial Phosphorus [PDF]
Plant Physiology, 2011 Microorganisms are integral to the soil phosphorus (P) cycle and as such play an important role in mediating the availability of P to plants. Understanding the microbial contribution to plant P nutrition and opportunities for manipulating specific microorganisms to enhance P availability in soil ...

Processes Governing Phosphorus Availability in Temperate Soils [PDF]
Journal of Environmental Quality, 2000 AbstractPhosphorus losses from agricultural soil to water bodies are mainly related to the excessive accumulation of available P in soil as a result of long‐term inputs of fertilizer P. Since P is a nonrenewable resource, there is a need to develop agricultural systems based on maximum P use efficiency with minimal adverse environmental impacts.

Silicon increases the phosphorus availability of Arctic soils [PDF]
Scientific Reports, 2019 AbstractPhosphorus availability in soils is an important parameter influencing primary production in terrestrial ecosystems. Phosphorus limitation exists in many soils since a high proportion of soil phosphorus is stored in unavailable forms for plants, such as bound to iron minerals or stabilized organic matter. This is in spite of soils having a high

Evaluation of chemical amendments to control phosphorus losses from dairy slurry [PDF]
, 2011 peer-reviewedLand application of dairy slurry can result in incidental losses of phosphorus (P) to runoff in addition to increased loss of P from soil as a result of a buildup in soil test P (STP). An agitator test was used to identify the most effective

Phosphorus Availability for Plant Uptake in a Phosphorus‐Enriched Noncalcareous Sandy Soil
Journal of Environmental Quality, 2004 ABSTRACTMining soil phosphorus (i.e., harvesting P taken up from the soil by a crop grown without external P addition) has been proposed as a possible management strategy for P‐enriched soils to decrease the risk of P leaching. We performed a pot experiment in a greenhouse where grass was cropped on a P‐enriched noncalcareous sandy soil at zero P ...

Phosphorus activators contribute to legacy phosphorus availability in agricultural soils: A review [PDF]
Science of The Total Environment, 2018 Phosphorus (P) is one of the most limiting macronutrients for crop productivity and P deficiency is a common phenomenon in agricultural soils worldwide. Despite long-term application of phosphate fertilizers to increase crop yields, P availability is often low, due to the high affinity of phosphate for the soil solid phase.
