1、Linking phosphorus fertility to soil microbial diversity and network

The results showed that the cultivation of citrus results in soil phosphorus (P) accumulation, with significantly higher available and mineral-bound phosphate contents than those found in soils of natural forests.

2、集约化柑橘种植抑制土壤磷循环微生物活性

The results showed that citrus cultivation could lead to a decrease in soil pH and an accumulation of available phosphorus in the soil, with a content as high as 112 mg·kg -1, which was significantly higher than that of natural forests (3.7 mg·kg -1).

In this study, we evaluated the impact of chemical fertilizer on bacterial community diversity and ecological network at 75 citrus sites in a watershed where chemical fertilizer is continuously applied.

[Intensive Citrus Cultivation Suppresses Soil Phosphorus Cycling

The results showed that citrus cultivation could lead to a decrease in soil pH and an accumulation of available phosphorus in the soil, with a content as high as 112 mg·kg -1, which was significantly higher than that of natural forests (3.7 mg·kg -1).

[Intensive Citrus Cultivation Suppresses Soil Phosphorus

Soil microbes are key drivers in regulating the phosphorus cycle. Elucidating the microbial mineralization process of soil phosphorus-solubilizing bacteria is of great significance for improving nutrient uptake and yield of crops.

Soil pH and phosphorus drive the canonical nitrifiers and comammox

Soil pH and P content were the major factors shaping nitrifying communities. Ammonia oxidizing bacteria (AOB), archaea (AOA), nitrite oxidizing bacteria (NOB) and complete ammonia oxidizers (comammox Nitrospira) are major players in nitrification.

Microbial phosphorus cycling shaped by citrus

The impacts of intensive citrus cultivation on soil phosphorus accumulation, as well as the diversity and community structure of phosphorus-cycling microorganisms, remain poorly understood.

Soil pH and phosphorus drive the canonical nitrifiers and comammox

Here, we chose soil samples from citrus orchards that had been planted for 5 years (5Y), 10 years (10Y), 20 years (20Y) and 30 years (30Y), and adjacent woodland (NF), to study the response of nitrifiers to long-term citrus plantation using quantitative PCR and MiSeq sequencing.

Effects of different fertilizer applications on citrus rhizosphere soil

Abstract: To understand the effects of different fertilizer applications on soil quality and arbuscular mycorrhizal colonization, we examined the changes in soil physical and chemical properties, mycorrhizal colonization and propagules, and their relationships in citrus under inorganic fertilization (IF), organic fertilization (OF), combined organic and inorganic fertilization (CF), and no ...

Citrus, also known as the "King of Oranges," is a popular fruit in the citrus family, prized for its unique flavor and nutritional value. During its cultivation, phosphorus fertilizer plays a critical role in promoting growth and development. Below are the key functions of phosphorus fertilizer in citrus production:

1. Promoting Root Development

Phosphorus fertilizer provides essential phosphorus, which stimulates root growth and development. As a vital nutrient, phosphorus participates in key metabolic processes such as the synthesis of nucleic acids, proteins, and lipids, as well as energy production. By increasing soil phosphorus levels, this fertilizer enhances root proliferation, improving water and nutrient absorption. Healthy roots also boost soil water retention and aeration, fostering robust plant growth.

2. Enhancing Fruit Quality

Phosphorus fertilizer accelerates fruit development, resulting in smoother skin, vibrant color, juicy flesh, and superior taste. It increases sugar, vitamin, and mineral content, while reducing acidity. Studies show that optimal phosphorus application significantly raises soluble solids content and improves flavor, making it indispensable for premium fruit quality.

3. Facilitating Flower Bud Differentiation

Phosphorus is crucial for flower bud formation. Timely application before blooming boosts bud quantity and quality, ensuring stronger shoots. This directly translates to higher flowering and fruit-setting rates, ultimately increasing yield.

4. Improving Stress Resistance

Phosphorus strengthens the plant’s ability to withstand adverse conditions. It enhances soil water retention, mitigating drought impacts, and reduces pest/disease susceptibility. Additionally, phosphorus optimizes photosynthesis, improving drought, cold, and salt-alkaline tolerance, thereby enhancing overall resilience.

5. Balancing Nutrient Uptake

Phosphorus ensures equilibrium among nutrients like nitrogen, potassium, and magnesium, preventing deficiencies or excesses. It promotes efficient absorption of major elements, supporting healthy growth and preventing imbalances.

6. Boosting Fertilizer Efficiency

Phosphorus maximizes nutrient use by addressing the plant’s phosphorus needs, reducing waste from overapplication. It synergizes with other fertilizers (e.g., nitrogen), enhancing overall efficiency and minimizing environmental impact.

7. Enhancing Micronutrient Absorption

Phosphorus forms complexes with micronutrients (e.g., calcium, iron, zinc), increasing their availability. This improves uptake and utilization of these essential elements, optimizing plant health.

8. Extending Shelf Life

Phosphorus fertilizer prolongs fruit freshness by promoting sugar accumulation and organic acid/phenolic compound synthesis. Higher sugar content and antioxidants delay senescence, maintaining texture and flavor post-harvest.

9. Improving Soil Structure

Phosphorus loosens compacted soil, enhancing aeration and root penetration. It also stimulates microbial activity, accelerating organic matter decomposition and enriching soil fertility.

10. Promoting Ecological Balance

Sustainable phosphorus use reduces chemical reliance, lowering agricultural pollution. It supports soil microbiota diversity, enabling crop rotation/intercropping and efficient land use, aligning with eco-friendly practices.

Phosphorus fertilizer offers multifaceted benefits in citrus cultivation, including enhanced growth, improved fruit quality, stress resistance, nutrient balance, and ecological sustainability. Strategic application is vital for maximizing yield, quality, and resilience in citrus farming.
