Publisher Summary Diagnosis of the mineral–nutrition problem of soybeans is facilitated by knowing the cardinal concentrations in the total plant and plant parts, which define and separate deficiency, adequacy, and luxury levels of nutrition. Uptake rates and the translocation of nutrients within the plant is prerequisite information for understanding nutrition problems. In spite of the recognition of these facts by agronomists and plant nutritionists, these values and related information are most incomplete for soybeans and many other crops. This chapter discusses each nutrient separately under the subtitles of nutrient contents in the plant at various stages of growth, uptake rate, translocation, and fertilization. |
