Q: As against an acceptable level of ‘soil organic carbon’ of well over 5 percent, soils in Punjab are said to have levels far below 1 percent. R: Besides, 5.3 billion tonnes of soil is eroded annually, at a rate of 16.4 tonnes/hectare. S: The nutrient imbalance has been skewed by the overuse of urea (N) vis-a-vis phosphatic (P in chemical parlance) and potassic (K) fertiliser.

Sentence 1- Sentence P introduces the subject of the paragraph and that is why the first sentence in sequence. The subject here is the effects of the excessive use of chemicals during Green Revolution.
Sentence 2-Sentence Q is next in sequence as it elaborates the point of depletion of soil nutrients, raised in sentence P.
Sentence 3-Sentence R begins with ‘besides’ which means it is a continuation of the previous sentence. It provides another fact in the matter.
Sentence 4- Sentence S is last in sequence as it provides a conclusion to the paragraph.
