Farmers surround the fields with hedgerows during high insolation period to:
prevent the reduction in photosynthetic activity.
reduce evapotranspiration.
create conditions for plants to close their stomata.
prevent wilting of plants.

– High wind speed increases the rate of both evaporation and transpiration.
– By reducing wind speed, hedgerows decrease the rate of water loss from the field, helping to conserve soil moisture and reduce plant water stress.
– While reducing water stress can indirectly help prevent wilting and support photosynthesis, the direct mechanism addressed by reduced wind speed is the reduction of water loss through evapotranspiration.
– Hedgerows also provide habitat for wildlife and can help prevent soil erosion.
