Explanation:
Nitrogen is an essential element for plant growth and development; however, due to environmental pollution, high nitrate concentrations accumulate in the edible parts of these leafy vegetables, particularly if excessive nitrogen fertilizer has been applied. Consuming these crops can harm human health; thus, developing a suitable strategy for the agricultural application of nitrogen fertilizer is important. Organic, inorganic, and liquid fertilizers were utilized in this study to investigate their effect on nitrate concentrations and lettuce growth. The results of this pot experiment show that the total nitrogen concentration in soil and the nitrate concentration in lettuce increased as the amount of nitrogen fertilizer increased. If the recommended amount of inorganic fertilizer (200 kg·N·ha−1) is used as a standard of comparison, lettuce augmented with organic fertilizers (200 kg·N·ha−1) have significantly longer and wider leaves, higher shoot, and lower concentrations of nitrate.
Nitrogen is a critical element for plant growth and development; however, due to environmental pollution, high nitrate concentrations get in the edible regions of these leafy vegetables, particularly if excessive nitrogen fertilizer has been involved.
What are nitrate-containing fertilizer?
The main nitrate fertilizers exist as ammonium, sodium, potassium, and calcium salts. Nitrate exists highly reachable and can efficiently travel with water from the soil if there stands excessive rainfall and can get groundwater.
Nitrates in the soil exist as a primary source of nitrogen which is important for plant growth. Under normal conditions, nitrates are transformed to protein in the plant at about identical rates as they exist absorbed into the root system.
