What practices can reduce nitrogen loss from agricultural fields?

The incorporation of fertilizers into the soil and the use of cover crops are effective practices for reducing nitrogen loss from agricultural fields. When fertilizers are incorporated into the soil, it minimizes the potential for nitrogen runoff and leaching into waterways, as it allows for better absorption by the plants and reduces surface water movement that can transport nitrogen away from the root zone.

Cover crops, on the other hand, play a crucial role in improving soil structure, enhancing nutrient cycling, and preventing soil erosion. They absorb leftover nitrogen from the previous crops, which can prevent it from being lost through leaching during dormant periods. Additionally, cover crops can help to retain moisture and protect the soil from compaction, further contributing to better nutrient management.

These combined practices lead to improved nitrogen utilization efficiency, promoting sustainable agricultural practices while balancing productivity and environmental protection.
