Texts: Can someone explain the first question, please? And in detail? 1. Decide whether A/B soils are acidic or alkaline, and what are their saline levels (refer to the information in Table 1 below). Soil A is loam soil, and Soil B is sandy soil. While making this conclusion, use only the measurements on factors of 1:5 soil:water ratio, 25 degrees Celsius, and 10 minutes balancing time. 2. Decide whether increased temperature/stirring time/soil:water ratio will increase/decrease/not impact the measurement of soil pH/EC for different soil types. 3. Discuss the considerations on management practices under different pH/EC conditions. Table 1: Salinity classes in electrical conductivity (EC) for different soil textures EC range for Salinity class sands (S/cm) Non-saline: 0-140 EC range for loams (S/cm): 0-180 EC range for clays (S/cm): - Slightly saline: 140-280, 190-360, 250-500 - Moderately saline: 280-570, 360-720, 500-1000 - Highly saline: 570-1140, 720-1450, 1010-2000 - Severely saline: 1140-2280, 1450-2900, 2010-4000 - Extremely saline: >2280, >2900, 4000
