Abstract. Rice is subjected to high iron (Fe) levels in acidic lowland soils which results in disturbance of basic metabolism, several changes in physiological processes and as a consequence reduction in productivity. In response to Fe toxicity in soils, rice like other plants produce a number of hormones (also known as phytohormones

3- Use Organic Mulch. Organic mulch, such as wood chips, straw, and leaves, is a natural solution for iron-rich soil. Organic mulch steadily decomposes over time, adding organic matter to the soil and assisting in building remediation of excess iron deposits. The organic matter in mulch can also release hydrogen ions, which can reduce soil

· Iron (Fe) is the fourth most abundant mineral in the Earth's crust essential for plant growth. However, if overloaded, Fe becomes toxic for plants as a highly reactive Fenton catalyst. Higher plants have developed two distinct adaptive strategies to cope with low Fe availability in soils, such as the reduction-based strategy (Strategy 1) in

Fe 2+, on the other hand, is mobile and available to plants. The causes of iron toxicity, as we’ll see, are usually because of an imbalance in Fe 2+ vs. Fe 3+ rather than a lack or abundance of iron in the soil. This imbalance leads to too much iron available to the

2 Iron uptake Iron uptake in plants has classically been divided into Strategy I and Strategy II, also known as reducing and chelating strategies, respectively. 7 The main difference between both strategies is the oxidation state of iron when taken up by the plant: ferrous Fe 2+ for Strategy I and ferric Fe 3+ for Strategy II.

4 · Is the Cast Iron Plant toxic to cats? In short, yes, the Cast Iron Plant is toxic to cats. The plant contains saponins, which can cause symptoms such as vomiting, diarrhea, and drooling if ingested by cats. While the toxicity level is considered mild to moderate, it is still important to keep this plant out of reach of curious feline companions.
