WebIn other words, crop water requirement is total water demand for growing a crop. Crop water demand can also be expressed in term of supply as: WR = IRR + ER +ΔS +GWC (26.2) Where: WR = Total depth of water required during the life of crop irrespective of source. CU = Consumptive use (total water required for all plant processes) ER = … WebLeaching Requirement 9,846 views Nov 11, 2024 128 Dislike Share Save Agricultural Engineering Crack GATE Online 8.34K subscribers This is basic and fundamental topic …
Leaching Meaning - Definition, Types, Advantages and ... - BYJUS
WebIt can be calculated using the soil properties, the efficiency of the irrigation system and the leaching requirement (which is a function of water quality and salt tolerance of the crop). t = RAW / I (1-LR) e Where RAW – Readily available water I – Soil infiltration rate LR – Leaching Requirement e – Irrigation efficiency (fraction) WebFrom the equation it is found, Na + = EC/100 – (Ca 2+ + Mg 2+) where . EC = mSm-1. Na + = Ca 2+ and Mg 2+ concentration = mel-1. ... Calculate the electrical conductivities of both irrigation and drainage water in mSm-1 and leaching requirement (LR) of the irrigation water in percentage. Solution: rajasalmi
