Plant Nutrition Diagnostics: Broccoli
As part of an expanding series, this book provides readers with a valuable diagnostic tool through its unique collection of photographs documenting nutrient deficiency symptoms in broccoli. Once the underlying deficiency is known, strategies can be developed that help avoid losses in crop yield or quality. This book begins by providing generalized information on plant nutrient deficiency, which is followed by hundreds of images with accompanying text descriptions documenting deficiency symptoms for nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, iron, and zinc.
