A study looked at how water and nitrogen affect nutrient uptake in maize plants. They found that as the plants grew, they took in more nutrients like nitrogen, phosphorus, and potassium. The rate of nutrient uptake was highest at the beginning and decreased over time. Nitrogen and potassium were absorbed faster than phosphorus. Providing more water and nitrogen increased the amount of nutrients taken up by the plants, leading to higher crop yields. Overall, the study showed that nutrient uptake in maize plants changes over time and can be influenced by water and nitrogen supply.
