Answer:
because the maize plant will take in the nitrate and use it to make proteins for growth.
The concentration of nitrate ion (nitrogen) in the soil decreases after the farmer plants maize plants in the field because the maize plants have taken up these ions.
To develop and produce, maize plants need a lot of nitrogen. 160 kg/ha of nitrogen are removed on average by maize crops.
Due to its function in photosynthesis and other biological activities like mineral and water absorption, vacuole storage, and xylem movement, nitrogen is a crucial nutrient for maize and a major regulator of grain output.
The growth, yield, and quality of maize crops are most strongly influenced by nitrogen.
Fertilizer with nitrogen is necessary for healthy leaf growth.
Less photosynthesis, which is necessary to store starch in grains, occurs as a result of smaller leaves.
