This study develops a model based on the yield potential of various soil types in 12 Iowa counties to estimate the potential value of switching from uniform to variable fertilizer rates. Results indicate modest increases in the gross returns over fertilizer costs, ranging from $7.43 to $1.52 per...

Studies examining the value of switching to a variable rate technology (VRT) fertilizer program assume producers possess perfect soil nitrate information. In reality, producers estimate soil nitrate levels with soil sampling. The value of switching to a VRT program depends on the quality of the...

The total expected cost of sequestering carbon in agricultural soils is estimated under a possible EQIP program offering a per-acre subsidy to adopt conservation tillage and a carbon credit program where producers can sell their carbon credit in an external market. Both programs are compared to...

Beginning in the early 1980s, the government of Egypt embarked on an aggressive initiative to progressively change its centrally planned economy to a system more dependent on domestic and international markets. The agriculture and food sectors have taken the lead in the economic reforms. This...
