Question
Phosphorus availability to plants is the maximum in the
pH range of:Solution
Soils with inherent pH values between 6 and 6.5 are ideal for P-availability, while pH values below 5.5 and between 7.5 and 8.5 limits P-availability to plants due to fixation by aluminum, iron, or calcium

A boat can travel 30 km upstream and 45 km downstream in 6 hours. Find the speed of the boat in still water if the speed of the stream is 4 km/h.
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
(3.21) ? + 37.92 ÷ 1.98 = (5.99 + 3.99) 2
√(195.99 X 8.99 X 15.87) X ³√124.99 = ? X 11.99
? + 163.99 – 103.01 = 24.01 × 6.98
