Initial physic nut nutrition and potassium balance in the soil-plant system

Abstract: A B S T R A C TThe objectives of this study were to evaluate the mineral nutrition and the response of physic nut to potassium fertilization as well as to assess whether the species can absorb K from the non-exchangeable soil fraction. The study was conducted in a greenhouse, in randomized blocks, and with four repetitions. Physic nut plants were cultivated in plastic recipients filled with 50 dm 3 of a Dark Red Latosol fertilized with rates of 0, 40, 80, 120 and 160 mg K dm -3 of soil. One hundred and fifty d… Show more
