1、The Phosphorus

This review presents a summary of latest advances in the activation of insoluble Fe-P complexes by soil properties, microorganisms, and plants. Furthermore, we elucidate the physiological and molecular mechanisms underlying how plants adapt to Fe-P interactions.

2、Phosphorus applications adjusted to optimal crop yields can help

Once the capital, maintenance or wasted phosphorus fertilizer rates were determined for the appropriate crop, fertilizer rates were summed to the country and continent levels.

3、Increasing phosphorus fertilizer value of recycled iron phosphates by

Iron (Fe) minerals are commonly used to remove phosphorus (P) from waste streams, producing P-loaded Fe (III) oxides or Fe (II) phosphate minerals (e.g., vivianite). These minerals may be used as fertilizers to enhance P circularity if solubilized in soil.

4、Recycled Iron Phosphates: A New Phosphorus Fertilizer for Paddy Rice

Recycled iron phosphates are effective P fertilizers in paddy rice, highlighting their potential to close the P cycle by linking P recovery from waste streams with P reuse in agriculture.

5、Soil and Mineral Nutrients in Plant Health: A Prospective Study of Iron

With serious ecological and economic impacts, the use of chemical fertilizers that adversely affect plant health put forth the need to have crops with improved Fe and P requirements toward reducing the use of fertilizers in agricultural practices.

Sustainable plant

Inorganic phosphate (P i) is considered the most readily available form of soil P [6] and its availability to plants is strongly influenced by soil pH levels. When pH levels drop below 5.5, phosphate (P i) binds with iron (FePO 4) and aluminum (AlPO 4).

Crop acquisition of phosphorus, iron and zinc from soil in cereal

It is therefore important to enhance P-use efficiency in crop production through optimized application of P fertilizers and utilization of residual P and other P pools from soils.

The Crucial Role of Iron and Phosphate in Agriculture: Enhancing Crop

In the realm of agriculture, iron and phosphate are two essential nutrients that play a critical role in plant growth and development. Understanding their significance can enhance crop yields and improve soil health.

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.

Iron Fertilizers

The use of iron fertilizer for crop plants in the form of Fe 2 O 3 nanoparticles is gradually gaining attention, as it is helpful in the eradication of iron deficiency in soils and crops.

In agricultural cultivation, iron and phosphate fertilizers are two critical types of nutrients. They play a vital role in crop growth and yield. Below, I will detail which crops require iron and phosphate fertilizers, as well as the application methods for these nutrients.

Crops Requiring Iron Fertilizer

1. Legumes:

   • Soybeans, mung beans, and other legumes require significant iron to synthesize chlorophyll, essential for photosynthesis.
   • Iron deficiency leads to yellowing leaves and, severe cases, necrosis.

2. Brassicaceae Vegetables:

   • Examples include rapeseed, mustard, and spinach. These vegetables demand high iron during growth.
   • Iron is crucial for chlorophyll synthesis; deficiency causes stunted growth, yellowing leaves, or death.

3. Cruciferous Vegetables:

   • Cabbage, Chinese cabbage, and similar vegetables require substantial iron during early growth stages.
   • Iron deficiency impairs normal development, resulting in thin, pale leaves.

4. Root Vegetables:

   • Radishes, potatoes, and others also heavily depend on phosphorus.
   • Phosphorus promotes root development and enhances disease resistance.

5. Nightshade Vegetables:

   • Tomatoes, eggplants, and the like need moderate phosphorus for healthy growth.
   • Phosphorus increases fruit sugar content, boosting yield and quality.

6. Cucurbitaceous Vegetables:

   • Cucumbers, pumpkins, etc., require attention to phosphorus needs.
   • Phosphorus accelerates fruit maturation and improves productivity.

7. Medicinal Plants:

   • Ginseng, astragalus, and other herbs demand high levels of both iron and phosphorus.
   • Iron deficiency weakens growth and reduces potency; phosphorus shortages lower quality and yield.

8. Other Crops:

   • Grains like corn and wheat may not require as much iron or phosphorus as above, but proper application still enhances yield and quality.

Crops Requiring Phosphate Fertilizer

1. Legumes:

   • Soybeans, mung beans, etc., rely on phosphorus for protein and nucleic acid synthesis.
   • Deficiency causes stunted growth, yellowing leaves, and necrosis.

2. Brassicaceae Vegetables:

   • Rapeseed, mustard, spinach, and others have high phosphorus demands.
   • Phosphorus strengthens roots and disease resistance.

3. Cruciferous Vegetables:

   • Cabbage, Chinese cabbage, etc., need substantial phosphorus during early growth.
   • Deficiency leads to thin, pale leaves and poor development.

4. Root Vegetables:

   • Radishes, potatoes, and similar crops heavily depend on phosphorus.
   • Phosphorus supports root development and disease resilience.

5. Nightshade Vegetables:

   • Tomatoes, eggplants, etc., require phosphorus for balanced growth.
   • It enhances fruit sugar content, yield, and quality.

6. Cucurbitaceous Vegetables:

   • Cucumbers, pumpkins, etc., benefit from phosphorus.
   • It promotes fruit ripening and productivity.

7. Medicinal Plants:

   • Ginseng, astragalus, and others need abundant phosphorus.
   • Deficiency reduces medicinal quality and yield.

8. Other Crops:

   • Grains like corn and wheat may not demand as much phosphorus, but proper application improves yield and quality.

Different crops have varying requirements for iron and phosphate fertilizers. Fertilization should be tailored to specific crop needs. Both over- and under-application can harm growth, so scientific fertilization principles must be followed.
