1、Common Storage Methods for Phosphorus Among Macroelements

This paper provides a comprehensive review of the analytical methods used for characterizing atmospheric P species and the methods used for identifying P sources (e.g., oxygen stable isotope compositions of phosphate, δ 18 O P) discussing their respective suitability, advantages, and limitations.

This paper provides a comprehensive review of the analytical methods used for characterizing atmospheric P species and the methods used for identifying P sources (e.g., oxygen stable isotope compositions of phosphate, δ 18 O P) discussing their respective suitability, advantages, and limitations.

3、Role of vacuoles in phosphorus storage and remobilization

Algae and yeast store polyphosphates (polyPs), whereas plants store Pi and inositol phosphates (InsPs) in vegetative tissues and seeds, respectively. In this review, we summarize how vacuolar P molecules are stored and reallocated and how these processes are regulated and co-ordinated.

4、Exploring phosphorus fertilizers and fertilization strategies for

Novel approaches for packaging P, including bio- and bio-nano-chemistry, hybrid P formulations of water-soluble P with phosphate rock, and phosphate rock formulations with organic acids or microorganisms are described in this paper.

Phosphorus recovery from wastewater and bio

Examples of renewable sources of phosphorus are municipal wastewater from which phosphorus can be recovered by biological (Biological Excess Phosphorus Removal) or chemical (precipitation) methods.

Therefore, this paper aims to elaborate the different techniques for freshwater sampling and to introduce alternative laboratory methods for sample preservation and P fractionation.

Section 2: Primary Macroelements

Most commonly greenhouse managers use ammonium phosphate [NH 3 (HPO 3)] or diammonium phosphate [2NH 4 (HPO 3)] directly or as a component of a premixed commercial water-soluble or slow-release fertilizers to supply P to a crop.

Exploring internal phosphorus loads and management interventions

Here, we present a novel approach to characterize internal loading dynamics, leveraging multi-decadal monitoring data and a mass-balance model developed within a Bayesian inference framework.

Phosphate

The content presented in this review paper focuses on different mechanisms and modes of action of phosphate-solubilizing microorganisms, their contribution to phosphorus solubilization, growth-promoting attributes in plants, and the molecular aspects of phosphorus solubilization.

Mechanisms for improving phosphorus utilization efficiency in plants

Phosphorus (P) is an essential macronutrient required for plant development and reproduction (White and Hammond, 2008; Hawkesford et al., 2012).

Phosphorus is an essential nutrient for plant growth, playing a critical role in physiological processes such as development, metabolism, photosynthesis, and nutrient transport. Its storage and supply are vital for agricultural productivity, as phosphorus fertilization is a key practice to enhance crop yields and soil fertility.

Storage Methods for Phosphorus Fertilizers

1. Solid Granular Phosphate Fertilizers: The most common form, including ground phosphate rock and phosphatic powders. These are typically sold as granular or powdered products for ease of transport and application. While they allow precise dosing and convenient spreading, they are prone to caking and degradation when exposed to moisture. Proper storage is required to prevent clumping and spoilage.

2. Water-Soluble Phosphate Fertilizers: Designed for foliar spraying or irrigation, these fertilizers dissolve readily in water. Their advantage lies in direct plant absorption and high nutrient utilization. they have a shorter shelf life and must be stored in cool, dry conditions away from sunlight and heat to maintain stability.

3. Slow-/Controlled-Release Phosphate Fertilizers: Treated through chemical coatings or physical encapsulation, these fertilizers release nutrients gradually to match plants’ growth stages. They reduce labor costs and environmental loss by minimizing frequent applications. their higher cost and requirement for proper usage necessitate careful management.

4. Bio-Preparation Phosphate Fertilizers: Produced via biotechnology (e.g., microbial fermentation), these fertilizers are eco-friendly and enhance soil bioactivity. Despite their sustainability, they often involve higher production costs and environmental sensitivity.

5. Organic Phosphate Fertilizers: Derived from organic matter, these contain phosphorus in organic forms (e.g., organic phosphates) that plants can utilize. They are cost-effective and improve soil organic matter but release nutrients slowly and require conversion before direct absorption.

Recommendations for Storing Phosphate Fertilizers

1. Moisture and Heat Protection: Store in dry, well-ventilated areas. Avoid direct sunlight and high temperatures to prevent decomposition or caking.

2. Prevent Physical Damage: Handle with care to avoid crushing, as phosphate fertilizers are brittle and susceptible to mechanical stress.

3. Categorized Storage: Separate different types of phosphate fertilizers:

   • Store solid granular fertilizers independently to avoid contamination.
   • Keep water-soluble fertilizers in cool, shaded areas.
   • Isolate slow-/controlled-release and organic fertilizers for monitoring.

4. Regular Inspection: Check for changes in color, moisture, or odor. Address issues like caking, discoloration, or mold promptly by replacing or treating affected products.

5. Proper Application: Tailor methods to fertilizer types:

   • Broadcast or furrow-apply solid granular fertilizers evenly.
   • Dilute water-soluble types for drip irrigation or foliar spraying.
   • Follow timing guidelines for slow-/controlled-release products.
   • Incorporate organic fertilizers thoroughly into the soil.

effective storage and management of phosphate fertilizers require balancing scientific practices, environmental protection, and cost efficiency. By adhering to these principles, agricultural goals can be achieved while minimizing ecological risks.
