In this study, we investigated the total phosphorus loss in planting industry of China from 2012 to 2014.

3、Why Does Overapplication of Phosphorus Fertilizers Occur

The purpose of this study is to assess grower attitudes and behavior, with respect to proper application of phosphorus, and to investigate how certain exogenous factors might influence such applications. Data were analyzed from a survey conducted in North Carolina, USA, with 122 farmer participants.

4、Long

In general, long-term excessive P application exerted a remarkable and differentiated impact on the soil P fractions. An increase in the Sol-P and Al-P fractions could lead to enhanced P bioavailability and environmental risk in acidic red soils.

Mechanisms for improving phosphorus utilization efficiency in plants

Relatively large amounts of P fertilizer are applied to sustain crop growth and development and to achieve high yields. However, with increasing P application, plant P efficiency generally declines, which results in greater losses of P to the environment with detrimental consequences for ecosystems.

Phosphorus application rates and farmers’ perceptions of environmental

Farmer attitudes play a key role in nutrient management decisions, but few studies link farmer attitudes to phosphorus (P) fertilizer application rates. This study analyzes survey responses from 1650 Michigan corn farmers to assess P application behaviors and attitudes.

Sustainable Management of Phosphorus in Agriculture for Environmental

The fertilizer industry is concerned with the already rising cost of phosphate fertilizer associated with agricultural production. Because of this, scientific researchers are paying more attention to the long-term sustainable management of P-fertilizer.

Latest recommendations for managing phosphorus in agriculture

The application of both slurry and P fertilisers should aim to maintain the appropriate level of plant-available P for the farming system and soil type. Fertilisers with their larger concentration of P and physical properties can be stored and then applied at more appropriate times than slurry.

Better Management of Phosphorus Fertilizer in Intensive Cropping

The excessive application of phosphorus (P) fertilizer is becoming a major agricultural problem, which reduces the utilization rate of the P fertilizer and degrades soil quality.

In agricultural production, the rational application of phosphate fertilizers plays a crucial role in promoting crop growth, increasing yields, and improving quality. improper use, such as excessive application of phosphate fertilizers, can lead to a series of problems, including soil acidification, nutrient imbalances, and ultimately negatively impact crop growth and productivity. understanding how to address issues arising from overapplication of phosphate fertilizers is essential. Below are detailed strategies for managing excessive phosphate fertilizer use:

1. Adjust Soil pH

• Soil Testing: Use professional equipment to regularly test soil pH levels to ensure they remain within optimal ranges. If soil pH is found to be too high or low, take appropriate measures to adjust it.
• Increase Organic Fertilizers: Apply adequate organic fertilizers, such as farm manure or green manure, to enhance soil organic matter content and improve soil buffering capacity, which helps regulate pH levels.
• Apply Lime: When needed, apply lime (calcium hydroxide) in proper amounts to lower soil pH. Be cautious of overapplication, as this may cause soil compaction or other issues.

2. Reduce Phosphate Fertilizer Usage

• Precision Fertilization: Adopt scientific fertilization methods to accurately control the amount and timing of fertilizer application, avoiding excess use.
• Split Application: Divide phosphate fertilizer into multiple applications to reduce the dosage per application, thereby lowering the total amount used.
• Substitute with Other Nutrients: Where possible, replace part of the phosphate fertilizer with alternative nutrient sources to reduce reliance on phosphate.

3. Enhance Crop Phosphorus Absorption Capacity

• Optimize Fertilization Formulations: Ensure balanced supply of nitrogen, phosphorus, and potassium through scientific ratios to strengthen crops’ ability to absorb phosphorus.
• Adjust Crop Rotation: Tailor cropping patterns and rotation systems based on crop needs and soil conditions to improve phosphorus utilization efficiency.
• Use Slow-Release Fertilizers: Employ slow-release phosphate fertilizers to reduce nutrient release rates, extend nutrient availability periods, and facilitate crop uptake.

4. Strengthen Soil Management

• Deep Soil Tilling: Regularly deep-till soil to break up compacted layers, improve aeration, and enhance water retention, which benefits root development and nutrient absorption.
• Proper Irrigation: Maintain moderate soil moisture to avoid overwatering or drought, ensuring healthy root respiration and nutrient uptake.
• Plant Protection and Pest Control: Enhance pest and disease management to minimize crop damage and reduce phosphorus loss.

5. Monitoring and Evaluation

• Establish a Monitoring System: Develop a comprehensive soil and crop monitoring system to regularly collect data, analyze phosphate fertilizer usage, and assess outcomes.
• Adjust Fertilization Strategies: Refine fertilization plans based on monitoring results and crop performance to ensure scientific and rational phosphate application.
• Continuous Improvement: Continuously learn from experiences, explore more effective phosphate management techniques, and improve fertilization practices.

addressing excessive phosphate fertilizer application requires a multifaceted approach, including soil pH adjustment, reduced phosphate use, enhanced crop absorption, improved soil management, and systematic monitoring. By implementing these comprehensive measures, we can effectively mitigate the risks of overapplication, advancing sustainable agricultural development goals.
