Interpretive Summary

Improving Forage Production and Longevity of Alfalfa Stands with Balanced Fertilization, 2005 Alfalfa is a large consumer of phosphorus (P), potassium (K), and sulfur (S). In northeastern Saskatchewan, it is grown on approximately 200,000 acres for the dehydrated pellet market. Alfalfa for seed is grown on more than 120,000 acres in western Canada. In the absence of nutrient inputs, alfalfa cannot maintain its original productivity after about 3 years of hay production.

Improving Forage Production and Longevity of Alfalfa Stands with Balanced Fertilization, 2004. Alfalfa is a large consumer of phosphorus (P), potassium (K), and sulfur (S). In northeastern Saskatchewan, it is grown on approximately 200,000 acres for the dehydrated pellet market. Alfalfa for seed is grown on more than 120,000 acres in western Canada. In the absence of nutrient inputs, alfalfa cannot maintain its original productivity after about 3 years of hay production.

Improving Forage Production and Longevity of Alfalfa Stands with Balanced Fertilization, 2003. Alfalfa is a large consumer of phosphorus (P), potassium (K), and sulfur (S). In northeastern Saskatchewan, it is grown on approximately 200,000 acres for the dehydrated pellet market. Alfalfa for seed is grown on more than 120,000 acres in western Canada. In the absence of nutrient inputs, alfalfa cannot maintain its original productivity after about 3 years of hay production.

Improving Forage Production and Longevity of Alfalfa Stands with Balanced Fertilization, 2002 Alfalfa is a large consumer of phosphorus (P) and potassium (K). In northeastern Saskatchewan, it is grown on approximately 200,000 acres for the dehydrated pellet market. Alfalfa for seed is grown on over 120,000 acres in western Canada. In the absence of nutrient inputs, alfalfa cannot maintain its original productivity after about three years of production.

Improving Forage Production and Longevity of Alfalfa Stands with Balanced Fertilization, 2001 Alfalfa is a large consumer of phosphorus (P) and potassium (K). In northeastern Saskatchewan, it is grown on approximately 200,000 acres for the dehydrated pellet market. Alfalfa for seed is grown on over 120,000 acres in western Canada. In the absence of nutrient inputs, it cannot maintain its original productivity after about three years of production.

Improving Forage Production and Longevity of Alfalfa Stands with Balanced Fertilization, 2000 In northeastern Saskatchewan, alfalfa is grown on approximately 200,000 acres for the dehydrated alfalfa pellet market. Alfalfa for seed is grown on over 120,000 acres in western Canada. In the absence of nutrient inputs, alfalfa cannot maintain its original productivity after about three years of production, a result of weeds dominating the stands.
