Irrigation Need

Irrigation Need (1)

Soil texture and depth, depth of root development and soil moisture content govern the amount of water to be applied in any irrigation. To irrigate a nursery crop scientifically, nursery staff may need the following information to compute the amount of water to be applied.

1. The average depth of the plant layer (Conventionally this has been 18 cm).

2. The bulk density (BD)

The BD of most of the bare root nursery soils averages 1.3 g/cm3, ranging from 0.9 g/cm3 in sands to 1.6 g/cm3 in clay loams. The soil moisture retention curve is the per cent total soil moisture content by weight (TSMC by wt) plotted over soil moisture tension per cent at field capacity (-0..1 bar) n=and upper limit of dryness between (-0.5 and -0.75 bar). From the information, the amount of irrigation required to maintain the soil within the optimum moisture range fro growth can be calculated.
