Abstract
Fertilizer improves plant growth and productivity. An entry in the northern Idaho Fertilizer Guide series, this four-page publication offers fertilizer guidelines for nitrogen, phosphorus, potassium, sulfur and micronutrients, based on relationships between soil tests and yield responses for lentils. Also includes pH and agronomy/water-quality recommendations and a brief discussion of the visual signs of nutrient deficiency. The suggested rates should produce above-average yields if delivered using sound management practices.
