How does sod compete with fruit plants for water and nutrients?

In the context of fruit farming, permanent sod culture involves maintaining a ground cover of grasses or other vegetation. While this practice helps minimize soil erosion and can improve soil structure, the sod itself acts as a competitor to fruit plants by drawing upon the same limited resources in the soil.

Specifically, the sod competes with fruit trees and plants for:

• Water: The root systems of the sod absorb moisture from the soil, which can deprive fruit plants of the water necessary for their growth and fruit development, particularly during dry periods.1
• Nutrients: The sod consumes essential soil nutrients, potentially limiting the availability of these elements for the fruit crop.1

This competition can be particularly detrimental to vigorously growing fruit plants, such as peaches, grapes, and raspberries, unless the grower provides supplemental water and fertilizer to compensate for the loss. To manage this, many modern orchards utilize strip chemical weed control under the trees while maintaining mowed sod in the row middles.1
