Why is the planted area and production increasing? • Improved and stable economy • Good grain international prices in the mid 90’s • Climate change: Better precipitation regime in the western Pampas • Expansion of no-tillage • GR Soybean Varieties • Improved crop management (hybrids, varieties, weed and pests control, etc) • Greater use of fertilizers

Potential Growth of Grain Crop Production • Current grain production of 72 million t (35 million t soybeans) • Potential for 2011/12 of 110 million t (60% soybeans) • Increases in planted area of soybeans in the northeastern and northwestern regions • Narrow the yield gap

Constraints for increasing grain crop production in Argentina • Instability of the economy in the country • Lack of credit • Decline in soil fertility because of low nutrient use, especially in soybeans • Sustainability of rotations, soybeans monoculture! • Changes in climate? • Potential international market restrictions for GMO soybeans and corn
Nutrient Removal and Application in Wheat, Corn, Soybean and Sunflower Argentina - 2000/01 1392 657 280 In 2000/01, nutrient application was 24%, 42%, and less than 1% of the N, P, and K extracted per year, respectively Potential needs of 1 million ton N, 160 thousand ton P, and 650 thousand ton K
Nutrient Removal and Application in Wheat, Corn, Soybean and Sunflower Argentina - Average 1996/2001 1090 475 228 In the period 1996-2001, nutrient application was 29%, 45%, less than 1%, and 9% of the N, P, K, and S removed per year, respectively

Precision Agriculture in Argentina • Adoption of PA in Argentina started when INTA launched in 1996 a National Project of Precision Agriculture at EEA INTA Manfredi (Cordoba) leaded by Mario Bragachini (www.agriculturadeprecision.org) • Yield monitors, Global Positioning Systems (GPS) guidance and satellite images are increasingly used in large operations, while variable rate application (VRA) is rare. • Constraints for the adoption of PA are: high investment cost, high risk, low management-induced soil variability, and the widespread use of custom operators. • Adoption of PA is supported from: large farm operations with relatively high capital per worker, highly educated farm management, technology available from abroad, need for yield information, and ease of pooling data. • Remote sensing for agriculture in Argentina is becoming increasingly used. • The potential of precision farming in Argentina’s agriculture is to reduce costs in grain production, to increase productivity and make input use more efficient. • The challenge is to manage our agronomic knowledge to put these tools to work.
