Objective: Students will learn: Soil helps anchor plants and provides them essential elements of water and nutrients. Soil Plant Water Relationships 4 Figure 6. This basic knowledge of Soil Moisture Concepts is essential to managing the water in the soil, achieving irrigation efficiency, having effective drainage and good plant condition. Desiccation of soils decreases the intensity of the evaporation of soils. Basic relations of soil water and soil water flow important in irrigation design are presented, and methods to measure soil water content, pressure head, and conductivity are outlined. The air and water in the soil existed in the pore space in the soil, thus an understanding of soil porosity is a further step in understanding good turf management. 0000006866 00000 n Plants prevent soil erosion and provide organic matter. trailer << /Size 76 /Info 25 0 R /Root 31 0 R /Prev 393762 /ID[<2f3a9ee30140e6a32b79fcfc38effd3d><87732cfde80f11fe1dc428535fc6900d>] >> startxref 0 %%EOF 31 0 obj << /Type /Catalog /Pages 24 0 R /Metadata 26 0 R /AcroForm 32 0 R /FICL:Enfocus 27 0 R >> endobj 32 0 obj << /Fields [ ] /DR << /Font << /ZaDb 21 0 R /Helv 22 0 R >> /Encoding << /PDFDocEncoding 23 0 R >> >> /DA (/Helv 0 Tf 0 g ) >> endobj 74 0 obj << /S 123 /V 249 /Filter /FlateDecode /Length 75 0 R >> stream Soil Soil-Plant-Water relationships describes those properties of soils and plants that affect the movement, retention, and use of 'water essential to plant growth.
