1、A dynamic optimization of soil phosphorus status approach

Here, we propose a dynamic optimization of soil P status (DOP) approach aimed at managing long-term soil P status within the range of agronomic and environmental soil P thresholds, which...

2、Characteristics of phosphorus fertilizer application in the Yangtze

China plays an important role in international trade, promoting the circulation of phosphorus resources in the world, however, the current phosphorus cycle in China is in an unsustainable state (Zhou et al., 2017).

3、Past, present, and future use of phosphorus in Chinese

Large inputs of phosphorus (P) in chemical fertilizers and feed supplements since 1978 have improved soil P status in arable land in China, but have also created challenges by increasing P concentrations in manure and exacerbating water quality degradation.

4、How to Optimal Apply Phosphate Fertilizer for Jingzhanzi

Optimal phosphate application involves selecting the right fertilizer, controlling dosage, timing, and frequency, avoiding excess, integrating with other nutrients, managing soil pH, and maintaining soil health.

5、Phosphorus supply and management in vegetable production systems in China

These advances will provide a basis for improving PUE and optimizing phosphate fertilizer applications in vegetable production through regulatory measures. In addition, some policies are recommended that could ensure the safety of vegetables and improve product quality.

Fertilizer application rate and nutrient use efficiency in Chinese

We reviewed 476 papers from 1990 to 2021 to investigate the changes in the conventional application rate (CAR) and nutrient use efficiency (NUE) of fertilizers. The results indicated a decrease in the CAR of nitrogen (N) and phosphorus (P) fertilizers from 1993 to 2020.

A dynamic optimization of soil phosphorus status approach could reduce

Here, we propose a dynamic optimization of soil P status (DOP) approach aimed at managing long-term soil P status within the range of agronomic and environmental soil P thresholds, which facilitates the precise determination of optimal P application rates without the need for frequent soil testing.

Optimum phosphorus application rate for maintaining high yield and soil

From 2017 to 2019, the P application increased yield by 23.9% and profit by 20.4% on average compared to P0. The linear plateau model fit the relationships between P uptake, yield, profit, and phosphorus application rate.

The appropriate timing for phosphate fertilizer application in China varies depending on factors such as crop type, soil conditions, and climate. Below are some guidelines to help determine the optimal application cycles and methods:

1. Rice: During the rice growing season, phosphate fertilizer should typically be applied every 7-10 days. Rice has a high demand for phosphorus, requiring frequent replenishment. Spread the fertilizer evenly across the paddy field to maximize absorption.

2. Corn: Corn requires less phosphorus, so the application cycle can be extended. A typical cycle is 15-30 days. Apply the fertilizer uniformly around the root zone for better efficiency.

3. Wheat: Wheat has moderate phosphorus needs. The recommended application cycle is 15-20 days. Distribute the fertilizer evenly near the wheat roots.

4. Vegetables: Vegetables generally demand more phosphorus, necessitating shorter cycles. Apply phosphate fertilizer every 7-14 days, focusing on the root area.

5. Fruit Trees: Fruit trees require significant phosphorus but benefit from longer cycles. A typical interval is 20-30 days. Spread fertilizer evenly around the root base.

6. Flowers: Flowers need minimal phosphorus. Application cycles of 10-15 days are sufficient. Target the fertilizer near the root zone.

7. Lawns: Lawns require light phosphorus supplementation. Apply phosphate fertilizer every 7-10 days, focusing on the grassroots.

8. Large Farmland: For expansive agricultural fields, adjust cycles (15-30 days) based on crop growth and soil conditions. Ensure even distribution across the field.

9. Organic Fertilizers: Organic materials like chicken manure or cow dung, rich in phosphorus, can supplement chemical fertilizers. Apply these every 2-3 months, spreading them near the root zone.

10. Key Considerations:

    • Tailor application timing and methods to the crop’s growth stage and soil health.
    • Avoid over-fertilization to prevent waste and environmental harm.
    • Monitor crop health and soil moisture, adjusting plans as needed.
    • Follow local agricultural guidelines or expert recommendations.

optimizing phosphate fertilizer use requires considering crop type, soil, and climate. Proper timing and application techniques ensure healthy plant growth and improved yields.
