The assumption that the less-polluting technology is more profitable on low-
quality land is consistent with our earlier assumption that demand for the
chemical input is decreasing in land quality. The latter implies more chemicals
are applied to low-quality land than to higher quality land. Hence, the
policymaker would likely target low-quality land.” The policymaker does this by
promoting a less-polluting technology that is more profitable on low-quality land.”
Correspondingly, if demand ...

Thus once all the top-quality land is in use, as the intensity is increased, a stage
will be reached when labour can be used more productively on poorer quality
land. This is illustrated in Figure 8.6, which shows the marginal product curves for
labour on three different classes of land. Once OA hours of labour are used on
the most productive land, further labour would be used more productively by
extending on to second- quality land. As yet more labour is used, the marginal
product falls ...

Table 5.100 shows that 27 per cent of the total area of the -village is good quality
land, and about 19 per cent is of medium quality BI land and about 9 per cent Bu
quality land. The poor quality C land which constitutes 40 per cent of the total
area of the village is of great significance. In the year of enquiry the land
classified as poor quality C land was either covered with kans grass or water-
logged. The area affected by kans Agricultural and Food Productivity at Village
