1、Selenium biofortification in food crops: Key mechanisms and future

Along with staple food crops, biofortification of vegetables and fodder crops may also play vital role to fulfill dietary needs of Se in humans as well as in animals.

2、The Impact of Phosphorus Supply on Selenium Uptake During Hydroponics

In this study, the effects of P supply on subcellular distribution and chemical forms of Se in winter wheat were investigated in a hydroponic trial with medium Se level (0.1 mg Se L -1). P was applied with three concentrations (0.31, 3.1, and 31 mg P L -1) in the experiment.

3、Selenium biofortification of green spinach with optimum phosphorus

Selenium application in the form of Se (IV) solution at 120 g ha –1 to sandy clay soil was determined to be the optimum application rate, as higher rates reduced plant yield and decreased Se uptake by green spinach.

4、Phosphorus balancing for optimal crop yields

Matching phosphorus fertilizer applications to optimal thresholds required by crops mitigates the exhaustion of phosphorus resources and promotes agricultural sustainability.

5、Phosphorus and Selenium Interaction Effects on Agronomic

This study provides essential new insights into the efect of phosphorus on selenium uptake dynamics, sugar metabo-lism, and photosynthetic pigment synthesis, which may be useful for selenium biofortification programs in humans using cowpea.

Selenium in horticultural crops

Owing to Se's multiple functions, as well as it is requirement for human health, studies of Se in horticultural crops have increased. This article reviews Se and its functions in horticultural crops to provide a theoretical basis for practical applications.

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.

Selenium fertilization strategies for bio

Studies addressing the interaction between Se fertilization, soil properties, crop species and agronomic practices are however scant, hampering the development of a sustainable fertilizer strategy.

Phosphorus fertilization is essential for sustaining crop yields on

Overall, converting natural ecosystems to cropland, especially with P fertilization, significantly enhances soil phosphorus availability and crop yields, emphasizing the critical role of targeted P management in sustainable agriculture.

Selenium and phosphorus are two essential nutrients for plant growth, playing critical roles in physiological processes such as development, photosynthesis, antioxidant functions, and improvements in crop yield and quality. Below is a detailed analysis of selenium and phosphorus fertilization needs for various crops:

1. Corn

Selenium Requirements: As a major food crop, corn grains naturally accumulate selenium, which is vital for human health. Selenium, an essential micronutrient, boosts immune function and helps prevent cardiovascular diseases. Applying selenium-containing fertilizers during cultivation can enhance selenium content in corn, better meeting human dietary needs.

Phosphorus Requirements: Phosphorus is indispensable for corn growth. It promotes root development, improves drought and disease resistance, and enhances photosynthesis, thereby increasing growth rate and yield. Proper phosphorus fertilization optimizes corn quality and productivity.

2. Soybean

Selenium Requirements: Soybeans are rich in selenium, offering significant health benefits. Selenium strengthens immunity, combats cardiovascular diseases, and acts as an antioxidant by scavenging free radicals. Selenium-rich fertilizers can further elevate selenium levels in soybeans, supporting nutritional goals.

Phosphorus Requirements: Soybeans demand substantial phosphorus, which fuels root growth, stress resilience, and photosynthesis. Adequate phosphorus fertilization accelerates growth and boosts both yield and seed quality.

3. Wheat

Selenium Requirements: Wheat grains naturally contain selenium, crucial for human health. Selenium supplementation via fertilizers can amplify its concentration in wheat, addressing potential deficiencies in diets.

Phosphorus Requirements: Phosphorus is vital for wheat’s root system, drought resistance, and photosynthetic efficiency. Targeted phosphorus application enhances growth speed, yield, and grain quality.

4. Rice

Selenium Requirements: Rice, a staple food, accumulates selenium in its grains. Fertilizing with selenium-rich inputs increases its bioavailability, contributing to healthier diets.

Phosphorus Requirements: Rice heavily relies on phosphorus for robust root development, stress tolerance, and efficient energy production. Optimal phosphorus use improves growth vigor, yield, and grain integrity.

5. Cotton

Selenium Requirements: Cotton seeds contain notable selenium levels, beneficial for human health. Selenium fertilization boosts seed selenium content, aligning with nutritional objectives.

Phosphorus Requirements: Phosphorus is critical for cotton’s root mass, disease resistance, and photosynthetic capacity. Balanced phosphorus application ensures higher yields and fiber quality.

6. Rapeseed (Canola)

Selenium Requirements: As an oilseed crop, rapeseed accumulates selenium, which aids in human antioxidant defenses. Selenium-enriched fertilizers elevate its nutritional value.

Phosphorus Requirements: Rapeseed requires substantial phosphorus for root expansion, stress mitigation, and oil synthesis. Proper phosphorus management enhances growth, oil yield, and seed viability.

Strategic use of selenium and phosphorus fertilizers can significantly improve crop nutrient profiles, addressing human dietary needs while promoting sustainable agriculture. careful monitoring is necessary to avoid over-fertilization, which may harm soil health and the environment.
