We emphasize increasing ridge height and controlling water input for basal fertilizer to minimize P loss. The application of P fertilizer increased the soil P pool, with labile P (L-P) and moderately labile P (M-P) increasing by 13–114 % and 23–111 %, respectively, compared to P 0.

Optimizing phosphate fertilization in relation to phosphorus supply capacity of soils in Yunnan maize producing areas [J]. Journal of Plant Nutrition and Fertilizers, 2022, 28 (6): 1039-1046.

Sustainable plant

Inorganic phosphate (P i) is considered the most readily available form of soil P [6] and its availability to plants is strongly influenced by soil pH levels. When pH levels drop below 5.5, phosphate (P i) binds with iron (FePO 4) and aluminum (AlPO 4).

Phosphorus applications adjusted to optimal crop yields can help

Here we match plant-available soil Olsen phosphorus concentrations to thresholds for optimal productivity of improved grassland and 28 of the world’s most widely grown and valuable crops.

Effects of Different Varieties of Phosphate Fertilizer Application on

【Objective】 Effects of different phosphorus (P) fertilizers application on soil P transformation as well as P uptake and utilization in wheat were investigated, so as to provide a theoretical basis for precise matching and efficient utilization of P fertilizer in soil - P fertilizer - crop system.

Factors influencing phosphorus placement and effects on yield and yield

The soil optimal fertilizer placement is further determined by the soil P content, the application rate of phosphate, the tillage system, and the prevailing climate conditions (Randall and Hoeft, 1988, Roberts and Johnston, 2015).

The need to prioritize sustainable phosphate‐based fertilizers

As well as finding new phosphate supplies, we ought to be prioritizing sustainable phosphate-based fertilizers. By adopting microbial, physical and chemical modifications, low-solubility phosphate minerals could be used in an efficient way for nutrient supply and heavy metal immobilization.

Phosphate fertilizers are indispensable in agricultural production, playing a crucial role in plant growth and development. Rational application of phosphate fertilizers can promote robust root systems, strong plant structures, and enhance crop yield and quality. when selecting soils for phosphate fertilizer application, factors such as soil type, climatic conditions, and crop requirements must be comprehensively considered.

Below are detailed recommendations for prioritizing phosphate fertilizer application based on soil types:

1. Alkaline (Calcareous) Soils: Soils with a pH between 6.5 and 7.5. These soils have high calcium ion content, which inhibits phosphorus solubility and absorption. For such soils, phosphate fertilizers with higher phosphorus content should be chosen. Additionally, adjusting irrigation practices and fertilization methods can improve phosphorus utilization efficiency.

2. Acidic Soils: Soils with a pH between 5.5 and 6.5. High aluminum ion content in these soils hinders phosphorus uptake by plants. Lower-phosphorus phosphate fertilizers are recommended here. Increasing organic fertilizer inputs can raise soil pH, promoting phosphorus availability and absorption.

3. Neutral Soils: Soils with a pH between 6.0 and 7.0. Iron ions in these soils may reduce phosphorus absorption. Medium-phosphorus phosphate fertilizers are suitable. Optimizing irrigation and fertilization techniques can further enhance efficiency.

4. Sandy Soils: Coarse-textured soils with poor water retention. Nutrients, including phosphorus, are prone to leaching or wind erosion. Slow-release or long-term phosphate fertilizers are ideal. Adding organic matter improves soil structure, retaining phosphorus longer.

5. Clay Soils: Fine-textured soils with high water retention. Phosphorus tends to accumulate near the surface, limiting plant access. Slow-release or long-term phosphate fertilizers are recommended. Increasing organic matter content boosts phosphorus availability.

6. Poorly Drained Soils: Soils with excess moisture. Phosphorus loss occurs due to leaching. Slow-release or long-term phosphate fertilizers are preferred. Improving soil structure with organic amendments reduces nutrient runoff.

Phosphate fertilizer selection should align with soil type and climate. For alkaline soils, use high-phosphorus varieties; for acidic soils, moderate-phosphorus options; neutral soils also benefit from moderate-phosphorus types. Sandy, clay, and poorly drained soils require slow-release or long-term formulations. Combined with optimized fertilization timing and methods, these strategies maximize phosphorus efficiency, fostering healthy crop growth and development.
