Question
……………………………is a key factor for
successful crop production and it is a measure of capacity of soil to supply plant nutrients.Solution
Soil fertility is a key factor for successful crop production and it is a measure of capacity of soil to supply plant nutrients. Soil fertility and fertilizers are very much closely related terms. Soil fertility acts as a ‘SINK’ where in plants can draw nutrients for maximum yield, where as fertilizer, acts as a ‘SOURCE’ wherein we can draw continuously different nutrients and also add to the sink.
120% of 25 + 80 X 2 = ?2 - 6
115% of 40 + 3 × 4 = ? × 11 – 8
20 + 160/? × 20 = 420
56 × 18 + ? × 21 – 49 × 12 = 63 × 26Â
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
What will come in the place of question mark (?) in the given expression?
7 X 18 + ? = (52 - 6) X 9
13/3 – (23/6) = ? – (22/9)
4.2 × 6.5 × 7.8 = ?
Determine the value of ‘x’ if x% of 500 plus {1250 ÷ x of 10} × 5 equals 130
