This chapter introduces the relationships between the turfgrass plant, the host soil, and the irrigation water, which are key to proper irrigation design and management. It provides information on water movement through different soils and water uptake by plant roots. It discusses the concept of evapotranspiration (consumptive use) and its role in the calculation of water requirements. The chapter also includes information on various turfgrass types, their water requirements, and their relative drought tolerances.
SOIL-WATER-PLANT RELATIONSHIPS
Irrigation concerns the relationship between how a soil holds and stores water and how a plant uses water. Although you do not need to know a great deal about soil physics or plant physiology for proper irrigation, you do need to have a general knowledge of soils and to be familiar with how a plant, in this case turfgrass, uses water and uptakes it from the soil. There are a number of terms and concepts you should be familiar with in order to understand the soil-plant- ... read full excerpt from Golf Course Irrigation: Environmental Design and Management Practices ebook
