What reading level is The Principles of Irrigation Practice book?
To quickly assess the difficulty of the text, read a short excerpt:
Wickson declares, however, that 20 acre-inches are ordinarily sufficient, annually, for the irrigation of citrus trees, and that 10 inches are frequently sufficient.
192. Other conditions of orchard irrigation. In young orchards, and occasionally hi old orchards, inter-culture is often practised. Corn, potatoes, beets, squash and various vegetables or small fruits are planted between the rows of trees. Moreover, to maintain the fertility of the land, cover-crops are occasionally planted between... the rows of older trees. Inter-tillage in orchards invariably means a higher water requirement than does clean cul- ture. The increase corresponds to the degree of inter- culture.
The great danger in orchard irrigation is over-irri- gation. Only by moderate irrigation can the root-system 324 IRRIGATION PRACTICE be so developed as to take care of the tree in seasons of drought. If too much water be used, the rising ground water will kill the roots and thus the trees. Trees that have been planted on soils with a water table near the surface do not send their roots into the water and are not injured; but, when the roots have gone deeply into the soil and then are immersed in the rising water, the tree is sooner or later killed.
