Restoration of Soil Health for Achieving Sustainable Growth in Agriculture

Bashir Ahmadl, Munir Ahmad, Zulfiqar Ahmad Gill


Total geographical area of Pakistan is 79.61 million hectares
(m.ha.). Area under cultivation is 21.59 m.ha.; of which, only 5.34
m.ha. (i.e., 25 percent) is free from soil limitations and is fit for
intensive agriculture [Mian and Mirza (1993)]. The remaining
agricultural lands have various types of problems including formation of
slow permeability, water logging, salinity and sodicity, and wind and
water erosion. Thus, on an average, three out of four hectares of
cultivated land in Pakistan are in poor health. This in turn is causing
temporary or permanent decline in the productive capacity of the land.
Therefore, poor soil health is posing serious threat to the sustainable
growth of agriculture. The most important on-farm effects of land are
summarised in Table 1.
