The effect of Ca and Mg concentrations in nutrient solution on the dry matter yield and Ca, Mg and K content of barley (Hordeum vulgare L.)
Dry matter production by barley grown in nutrient solution culture was reduced by concentrations of Ca or Mg greater than 8 mmol L−1. Johnston barley was somewhat more sensitive to high levels of CaExpand
In four greenhouse pot experiments, we studied the relationships of cationic ratios, K/(Ca + Mg), in top growth of corn (Zea mays L.) and grain sorghum (Sorghum bicolor L. Moench) to ratios ofExpand
Effect of potassium fertilizer on cation uptake and concentration in oat shoots
Pot experiments were carried out using a system in which root mats were in contact with a Danish soil for 24, 72 or 168 h. Different rates of K fertilizer (0–80 mg K/100 g soil) resulted in markedExpand
Magnesium, Ca, and K Concentration in Temperate-Origin Forage Species as Affected by Temperature and Mg Fertilization 1
Climate and Mg fertilizer effects on herbage Mg concentration of tall rescue, timothy, orchardgrass, and ‘Viking’ birdsfoot trefoil cultivars indicated that cool temperatures, per se, may be less limiting to Mg accumulation than previously thought. Expand
Effect of potassium and magnesium application to soils on the dry-matter yield and cation composition of maize
In a glasshouse experiment, fertilizer potassium and magnesium were applied in various amounts to 20 soils differing in the proportion of exchangeable potassium to the sum of the three exchangeableExpand
Potential Tetany Hazard of N-Fertilized Bromegrass as Indicated by Chemical Composition
The objective of this field experiment was to determine the effect of N fertilization on yield and chemical composition of smooth bromegrass (Bromus inermis L.) and the potential for grass tetanyExpand
