Calcium uptake by potted rice plants in response to fertilization treatments on Oxisol

Fig. 3c. Calcium uptake by potted rice plants in response to fertilization treatments on Oxisol. Treatments: 1. control; 2. lack of K, S, Ca, and Mg; 3. granular polyhalite (1 g pot-1); 4. soluble K, S, Ca, and Mg salts; 5. granular polyhalite (2 g pot-1); 6. powder polyhalite (1 g pot-1). More details are provided in Table 2. Different letters indicate statistical significant differences at P=0.05 (Duncan test).
