1、Exploring phosphorus fertiliser management in wheat production

Recent studies have examined the impact of crop rotation systems on the efficiency of P fertilisers, and Lv. (2016) found that wheat-rice rotation exhibits superior P fertiliser efficiency compared to wheat-maize rotation.

2、High Phosphorus Fertilization Increases Manganese Accumulation in Wheat

Previous studies have shown that high phosphorus (P) fertilization can significantly increase the Mn content in wheat grain; however, the underlying mechanisms remain unclear.

3、Optimizing Phosphorus Fertilization for Enhanced Yield and

Wheat (Triticum aestivum L.), one of the world’s most important staple crops, is particularly sensitive to phosphorus availability, making appropriate phosphorus fertilization a key and manageable strategy to optimize yield.

Effects of Phosphorus Fertilization on the Yield and Phosphorus

Compared with the -P treatment, the +P treatment significantly increased the wheat yield by 5.8%. Overall, the winter wheat yield showed a linear plus platform correlation with annual precipitation and precipitation in the summer fallow season.

Progress on mechanism on the phosphorus

However, the seasonal utilization efficiency of phosphorus fertilizer in Chinese wheat production is only 19%, making the improvement of phosphorus absorption and use efficiency a critical scientific issue in wheat nutrient management research.

Long

P fertilization with 26 kg ha −1 improved soil physical properties in both P-status soils, enhancing P use efficiency and increasing maize and wheat yields.

Impact of varied tillage practices and phosphorus fertilization regimes

The study highlights the potential of strategic soil management, particularly conventional tillage combined with phosphorus fertilization, to enhance wheat quality and yield.

Layered application of phosphate fertilizer increased winter wheat

Our results showed that, compared with surface fertilization, all the LF treatments significantly increased yield by 6.3–20.6% and PUE by 4.7–11.2% points. Furthermore, elliptical layered fertilization resulted in the highest yield and PUE rate.

Effects of Combined Nitrogen and Phosphorus and Reduced

<p>This study aimed to elucidate the effects of combined nitrogen and phosphorus and reduced fertilizer applications on the growth， nutrient utilization， and yield traits of wheat.

Optimizing Nitrogen and Phosphorus Fertilizer Application for Wheat

Enhancing crop productivity on alkali soils is essential for food security; however, excessive fertilizer use can lead to soil salinization. Wheat, as a key staple crop, requires an appropriate nitrogen-to-phosphorus fertilization ratio to optimize its yield, yet the ideal ratio remains unclear.

Wheat, as a crucial food crop, plays a pivotal role in global agricultural production. Phosphorus fertilizer, a key nutrient source, significantly impacts wheat growth. whether excessive phosphorus application is beneficial requires multifaceted analysis.

1. Positive Effects of Phosphorus Fertilizer on Wheat Growth

• Root System Development: Phosphorus fertilizer promotes root growth and nutrient/water uptake, vital for wheat survival under drought.
• Improved Photosynthesis: Enhances leaf photosynthetic efficiency, increasing assimilate production and overall yield.
• Grain Filling: Stimulates grain plumpness, boosting kernel weight and economic value.
• Stress Resistance: Moderate phosphorus strengthens tolerance to cold, drought, pests, and diseases, reducing yield losses from adversity.

2. Risks of Excessive Phosphorus Application

• Nutrient Imbalance: Overuse disrupts soil N-P ratios, hindering absorption of other nutrients.
• Soil Acidification: Accumulated phosphorus triggers acidic conditions, degrading soil fertility.
• Microbial Dysfunction: Disrupts soil microbial communities, reducing biological activity.
• Environmental Pollution: Excess phosphorus increases agricultural runoff risks, threatening ecosystems and human health.

3. Strategies for Rational Phosphorus Use

• Soil-Test Calibration: Tailor fertilization rates to soil type and crop needs based on scientific testing.
• Balanced Nutrient Management: Coordinate phosphorus with nitrogen and potassium to maintain soil equilibrium.
• Crop Rotation Practices: Avoid continuous phosphorus buildup by rotating crops or deep tilling.
• Controlled-Release Fertilisers: Reduce environmental loss using slow-release or controlled-release formulations.
• Precision Application: Deep placement and layered fertilization enhance efficiency while minimizing waste.

4. Case Studies

• Domestic Research: Field trials in Chinese regions confirm optimal phosphorus rates improve wheat yield and quality, guiding farmer practices.
• Global Insights: Countries like the U.S. leverage controlled-release fertilizers in wheat cultivation, effectively curbing pollution from excess phosphorus.

While phosphorus fertilizer benefits wheat, excessive use poses risks. Scientifically calibrated application ensures sustainable productivity, balancing yield gains with ecological protection.
