“…This observation agrees with those of Razmjoo and Henderlong (1997) and Papadakis, Dimassi, and Therios (2003), who also reported that the K level in plants is unaffected by soil B treatment.…”

The effect of nitrogen (N) on the boron (B) nutrition of plants is of great significance because N may promote or reduce B absorption. Therefore, a fertilizer factorial experiment of randomized complete block design was conducted in pots under greenhouse conditions using lettuce (Lactuca sativa L.) as test plant. Plants of lettuce were grown in a calcareous sandy clay loam soil with different N and B fertilizer levels to investigate the effect of applied N and B as well as their interactions on nutrient distribution in leaves and roots of lettuce plants. Treatments consisted of four levels of N (0, 200, 400, and 600 mg N kg −1 soil) and two levels of B (0 and 5 mg B kg −1 soil). The results showed that increasing N level up to 600 mg N kg −1 significantly increased soil nitrate (NO 3 − ) N and potassium (K) but had no effect on soil available phosphorus (P) and B. Application of 5 mg B kg −1 soil significantly decreased available K, whereas P concentrations increased. Nitrogen application increased leaf and root N and reduced leaf P and K. By increasing N concentration in the soil, leaf B concentration was reduced in all N treatments. However, B had no effect on the N, P, and K contents of leaves. In the case of roots, B was affected by N treatments and it was reduced significantly in the treatment of 600 mg N kg −1 soil + 5 mg B kg −1 soil. These results suggest that N fertilization potentially may prevent B toxicity and keep leaf B concentration at normal levels in lettuce plants. Therefore, the appropriate management of N fertilizers in soils with excess B is very important.

“…Overall, the effect of B on total yield was nonsignificant in northwestern Montana, similar to reported findings in literature (Grant and Miller, 1998; Pecinovsky and Lang, 2012; Razmjoo and Henderlong, 1997; Sapkota et al, 2017, 2018). Razmjoo and Henderlong (1997) found that application of B up to 2 kg ha −1 did not affect alfalfa yield in Columbus, Ohio on a Crosby silty clay loam soil. Similary, Grant and Miller (1998) and Sapkota et al (2018) reported no increases in alfalfa yield with increased B rate applications.…”

Boron (B) fertilization based on soil B status may prevent negative effects on alfalfa (Medicago sativa L.) yield and quality. Our objective was to determine the effects of foliar-applied B and water regimes on alfalfa yield and quality. A 2-yr (2016)(2017) study was done at Creston, MT in a fine sandy loam soil that tested 0.2 mg kg -1 B. Alfalfa was planted in 2016. Levels of B ranging from 0 to 2.24 kg B ha -1 were applied in association with three water regimes including rainfed, 50%, and 100% evapotranspiration (ET). There was no effect of B on yield or crude protein (P > 0.05) in either year. Both B fertilization and irrigation application increased petiole B concentration. In 2017, the water regime × B level interaction was significant specifically for the yield of the second cutting (P = 0.02), as well as for the relative feed value, neutral detergent fiber, and petiole B concentration in the third cutting (P < 0.05). Irrigation decreased (P < 0.01) forage quality only in the second cutting of 2016. Irrigation increased alfalfa yield by 45% in the establishment year (2016), but only by 12% in the following year. However, there was no yield difference observed (P > 0.05) between the 100ET and 50ET treatments each year, and irrigation water productivity decreased in the second year of alfalfa growth. The foliar application of B on a B-deficient soil did not increase yield or crude protein content of alfalfa, regardless of soil moisture availability. core Ideas• Application of B or irrigation increase petiole B concentration of alfalfa. • Increases of petiole B due to B fertilization did not increase alfalfa yield and crude protein.• Deficit irrigation did not reduce yield in alfalfa.• Regardless of water regime, application of B on B-deficient soil did not improve yield and crude protein of alfalfa.

“…This is supported by studies on isolated vacuoles (Kaiser et al, 1989 ). Sulfate application also increased potassium levels in e.g., alfalfa (Razmjoo and Henderlong, 1997 ). In studies with Norway spruce potassium, magnesium, and manganese were increased in the endodermis and mesophyll cells if sulfate was increased due to SO 2 fumigation.…”

Interactions of Sulfate with Other Nutrients As Revealed by H2S Fumigation of Chinese Cabbage

et al. 2016

Sulfur deficiency in plants has severe impacts on both growth and nutrient composition. Fumigation with sub-lethal concentrations of H2S facilitates the supply of reduced sulfur via the leaves while sulfate is depleted from the roots. This restores growth while sulfate levels in the plant tissue remain low. In the present study this system was used to reveal interactions of sulfur with other nutrients in the plant and to ascertain whether these changes are due to the absence or presence of sulfate or rather to changes in growth and organic sulfur. There was a complex reaction of the mineral composition to sulfur deficiency, however, the changes in content of many nutrients were prevented by H2S fumigation. Under sulfur deficiency these nutrients accumulated on a fresh weight basis but were diluted on a dry weight basis, presumably due to a higher dry matter content. The pattern differed, however, between leaves and roots which led to changes in shoot to root partitioning. Only the potassium, molybdenum and zinc contents were strongly linked to the sulfate supply. Potassium was the only nutrient amongst those measured which showed a positive correlation with sulfur content in shoots, highlighting a role as a counter cation for sulfate during xylem loading and vacuolar storage in leaves. This was supported by an accumulation of potassium in roots of the sulfur-deprived plants. Molybdenum and zinc increased substantially under sulfur deficiency, which was only partly prevented by H2S fumigation. While the causes of increased molybdenum under sulfur deficiency have been previously studied, the relation between sulfate and zinc uptake needs further clarification.
