Phosphorus (P) cycling in paddy soil is closely related to iron (Fe) redox wheel; its
availability to rice has thus generally been ascribed to Fe minerals reductive dissolution …

Simultaneous extraction of nutrients using ammonium bicarbonate–diethylene triamine
penta acetic acid (ABDTPA) extractant has been successful for highland soils, but its …

Phosphorus (P) loss from agricultural soils can negatively affect water quality. Models and
management to decrease losses increasingly focus on P that is available and transported …

Soil phosphorus (P) tests for flooded rice (Oryza sativa L.) generally present uncertainties for
estimating P availability. Bray 1, 1% citric acid, Mehlich 3, Olsen extractants (dry samples) …

Crop production is highly impacted by soil phosphorus (P) availability which is poor and
susceptibly affected by soil moisture. However, how water management and straw …

The limited availability of phosphorus (P) in the soil, which is affected by soil moisture, has a
significant impact on crop production. However, we still do not fully understand how water …

Introduction The physical properties of soil are essential because of their role in supporting
plant growth. These characteristics determine how the plant interacts with the soil …

In this experiment, when the strontium chloride–citrate acid extractant (0.02 M SrCl2–0.05 M
citrate) was used for extraction of calcareous soils with calcium carbonate greater than 70 g …

Individual malnutrition is a worldwide problem that mostly affects people whose diets (often
of plant origin) are deficient in essential vitamins and minerals. Low levels of micronutrients …

At global level rice paddy agroecosystems encompass over 150 million hectares, making
these peculiar anthropogenic environments the largest wetland areas of the world. Indeed …
