4R Plant Nutrition: A Manual for Improving the Management of Plant Nutrition - North American

International Plant Nutrition Institute


$ 30.00




4R Nutrient Stewardship is a new innovative approach for fertilizer best management practices adopted by the world’s fertilizer industry. This approach considers economic, social, and environmental dimensions of nutrient management and is essential to sustainability of agricultural systems. The concept is simple–apply the right source of nutrient, at the right rate, at the right time, and in the right place–but the implementation is knowledge-intensive and site-specific. The 4R Plant Nutrition Manual is a wiro bound, 130 page (8½ x 11 in.) book filled with illustrations, learning modules, and case studies. There are currently two versions of the manual: a fully Metric Version, and a North American Version that predominantly uses US (Imperial) units.
