Question
Tha soil having  pH value of < 8.5 with EC
(electrical conductivity) is > 4.0 millimhos/cm and ESP< 15, is ____ soil.ÂSolution
Characteristics of saline soils: Soil pH of <8.5 EC is >4.0 millimhos/cm. ESP is < 15. Dominated by sulphate and chloride ions and low in exchangeable sodium.
(49 x ?) / 3.5 + 389 = 627
14 × 6 + 9 × 11 = (82 – 3) × ?
779 + 136 – 334 = 270 + 121 + ?
414 ÷ 23 × 38 – 154 + 264 = ?
...√64 of √225 = √(25 + ?) X 12
What is 12% of 4% of 7% of 2 x 106 ?
35% of 840 + 162 = ? – 25% × 300
22.5% of 300 + 32.5% of 4500 =?
