Phosphorus placement for wheat and lupins in WA cropping systems [PDF]

, 2010
Significant vertical stratification of soil nutrients, particularly soil immobile nutrients (such as phosphorus (P)) in long-term zero-till fields has been reported in both Australia and overseas (White 1990; Howard et al. 1999).

Effect of Phosphorus Fertilization and Content of Plant-available Phosphorus (P-AL) on Algal-available Phosphorus in Soils

Acta Agriculturae Scandinavica, Section B — Soil & Plant Science, 1995
Abstract The fate of excess fertilizer P was studied using a sequential P extraction procedure of soil samples from two, PK fertilization field trials in southeastern Norway. At both sites there was an increase in the resin-P and NaHCO3-Pi (Pi = inorganic P) fractions with increasing P additions; both of these fractions were closely correlated to algal-

Improving the efficiency and sustainability of fertiliser use in drought- and submergence-prone rainfed lowlands in Southeast Asia [PDF]

, 2001
In the rainfed lowlands of South-East Asia, rice yields are low and often respond weakly to fertilizers. Studies of soils in Cambodia and North-East Thailand suggest that a complex combination of factors restrict rice yield and nutrient uptake in ...

Effects of sustanaible soil management on soil quality [PDF]

, 2010
The declining of soil fertility due to intensive agriculture represents the main constraint to agricultural productivity. Sustainability of agriculture may be threatened by the progressive reduction of soil organic matter without adequate restoration ...

Phosphorus release kinetics of applied phosphate is influenced by time and organic sources in clay loam and sandy clay loam soils

Soil & Environment, 2018
Adsorption and precipitation are major mechanisms that play an imperative role in immobilization of phosphorus (P) in various texture soils thus limiting the crop yields.

Phosphorus nutrition of chickpea under dry topsoil conditions as in the High Barind Tract of Bangladesh [PDF]

, 2012
In many parts of the world, notably in South Asia, crop intensification is resulting in more crops being grown on stored soil moisture, under which conditions the topsoil commonly dries out during crop growth.

Inorganic Phosphorus Fractions and Phosphorus Availability in a Calcareous Soil Receiving 21-Year Superphosphate Application

, 2010
A long-term (21-year) field experiment was performed to study the responses of soil inorganic P fractions and P availability to annual fertilizer P application in a calcareous soil on the Loess Plateau of China.

Soil management calculator for predicting phosphorus losses under cropping systems in Western Australia [PDF]

, 2011
Agriculture in many parts of the world is coming under increasing pressure to develop management practices that will minimise phosphorus (P) loss to the environment.

The Significance of Resorption During Anoxic Mobilization of Phosphorus [PDF]

, 2009
Phosphorus has a fundamental role in the regulation of biotic cycles in both aquatic and terrestrial environments. Phosphorus is in fact the limiting nutrient for plants in the majority of the cases.
