3. Why Soil Sample? – Budget Conscientious

4. Why Soil Sample? – Fertilizer Market Fluctuation

5. Population and Income Growth Drive Crop Consumption Global consumption of grains, oilseeds, fruits and vegetables has increased by nearly 2.5 times since 1970. World population over this time nearly doubled and per capita consumption increased by more than 30 percent as income growth in developing countries supported a shift to higher quality diets. With continued growth in population and income levels in developing countries, crop consumption is expected to approach 5 billion tonnes per year by 2020.

6. Application Deficit Is Not Sustainable Long-Term As corn and soybean production increased, so did the level of nutrient withdrawals. This resulted in a growing application deficit, as farmers have been drawing down reserves that had been built up in their soils. This practice is not sustainable in the long-term. Crop production is expected to increase in the years ahead and we believe more potash will be required to match the level of nutrients removed from the soil.
