Potassium Magnesium

In a two-pot experiment of Phaseolus vulgaris L., the influence of K and Mg gradated doses upon K, Mg and Ca content in the pods, stem and leaves was studied. The content of cations changed significantly in individual parts of the plant. The highest content of potassium was found within the dry matter of the pods (it exceeded 4%) and stalk (3–4%). The highest content of calcium (3–4%) and magnesium (0.4–0.8%) was found within the dry matter of the leaves. The effects of K gradated doses were revealed significantly in its higher content increase mainly in the leaves (by as much as 83%) and the decrease of calcium content (31%) and magnesium content (37%) was observed in the leaves and less in the stalks. The effects of Mg gradated doses were revealed in the non-significant increase in its content in the leaves and stalks and the decrease of the potassium content in the leaves (by 19%) and in stalks (11%) and even in the decrease of the calcium content (52%) mainly in the pods.

Magnesium Uptake

In a pot experiment on sphagnum peat soil the magnesium fertilization increased significantly the magnesium content of the grains and the straws of oats. The addition of potassium fertilization decreased the magnesium content when the plants received a magnesium fertilization. Without magnesium the rate of potassium fertilization did not have an effect on the magnesium content of the straws. The increase in the equivalent ratio of the three potassium rates and the two magnesium rates decreased the magnesium content of both the grains and the straws. Along with the magnesium fertilization the addition of lime decreased the magnesium content of the grains and increased that of the straws. Doubling the amount of the nitrogen fertilization with the magnesium fertilizer increased the magnesium content of the grains and the straws. In the case of magnesium deficiency the addition of lime or nitrogen did not have an effect on the magnesium content of the yields. The rate of magnesium, potassium, lime and nitrogen did not have an effect on the potassium content of the grains. The potassium content of the straws increased with the addition of potassium. Without the magnesium fertilization the potassium content, as well as, the ratios K/Mg and K/(Ca + Mg) in the grains and the straws were high. A part of the missing magnesium had, perhaps, been substituted for by potassium. The calcium content of the grains and the straws obtained without magnesium fertilization was significantly higher than the calcium content with magnesium fertilization. The oats substituted possibly in part also calcium for the missing magnesium. The effect of added magnesium, potassium, lime and nitrogen on the magnesium uptake by oats was discussed.

Growth and rates of photosynthesis of two accessions and two cultivars (Great Northern 1140 and Sutter Pink) of bean (Phaseolus vulgaris L.) were compared at 10, 15, and 23 °C in a controlled environment cabinet. The leaf area, dry matter, and rate of total apparent photosynthesis of one of the accessions was significantly higher after growth for 13 days at 10 °C than that of the commercial cultivars. This advantage was not maintained at 23 °C. In another experiment, growth of the same four cultivars was compared at light/dark temperatures of 10/10, 15/12, and 23/18 °C. The two accessions established a higher leaf area and accumulated more dry matter at the cooler temperatures than the commercial cultivars, but lost this advantage at the highest temperatures. In a field trial, the accessions had a similar rapid early growth but fell behind later in the season. Ideally, a bean cultivar for the Canadian prairie should incorporate the accession’s ability for rapid growth and leaf expansion at cool temperatures with a growth rate during mid-summer comparable to that of Great Northern 1140.

Under controlled conditions and utilizing three soils of Red Ferralithic (Eutric Ferrasols) type with low, medium and high available P we studied the effect over the production of dry matter and the extraction of N and P performed by the bean plant (Phaseolus vulgaris L.), produced by the addition in increasing dosage of P, between 0 and 280 kg P2O5/ha, with fixed basis of 60 kg K2O/ha and 40kg N/ha and inoculation with bacteria from the Rhizobium genera. The experimental results showed a plant response differentiated by the availability of P in the soil. In soils with low P contents there was a positive response in the three evaluated indexes, while in the other two soil samples the higher availability of P produced a smaller or negative response. We also discuss the functional relationship found among the evaluated indexes.

Abstract The aim of the study was to evaluate an effect of liming on chemical properties of the soil, magnesium content in the meadow vegetation and leachate water moving through the soil profile. The study was conducted in the growing seasons in the years 2012-2014. The study included three plots in two series: with lime and without lime. The plant material was subjected to dry digestion and ash was dissolved in HNO3 (1:3). The soil was mineralized in a muffle furnace and the ashes were dissolved in a mixture of HNO3 and HClO4 (3:1 v/v). In the obtained samples and in leaching water, estimated the content of phosphorus, potassium, magnesium and sodium by induction plasma emission spectrophotometer. In the soil content of assimilable phosphorus and potassium was determined by the Egner-Riehm method. The content of assimilable magnesium was determined by the Schachtschabel method and the pH of the soil by potentiometric method in water and in mol KC1·dm-3. Liming positively affected on soil pH and magnesium content in plants increasing its amount of about 15- 21% of dry matter with respect to not limed plots. In turn, lime fertilization negatively affected the content of magnesium in leachate water and the load eluted per unit area. Magnesium content in leachate water and the amount of loads eluted from limed plots were lower on average by 16-23% with respect to not limed plots.

Concentrates, one consisting primarily of oats and the other barley, were fed ad libitum to cows or at the rate of 1 kg per 3 kg of milk yield for an entire lactation. Calcium, potassium, magnesium and sodium content of the milk and milk yield were measured monthly. Potassium content and milk yield decreased and sodium content increased significantly (P < 0.05) with advancing stage of lactation. The calcium content of milk was significantly greater (P < 0.05) when the barley-based compared with the oat-based concentrate was fed. The sodium content of milk from cows fed concentrate ad libitum was significantly higher than from cows fed restricted amounts of concentrate. Ayrshire milk was significantly greater (P < 0.05) in magnesium concentration than Holstein milk.

Seven cultivars of Phaseolus vulgaris L. were grown in nutrient solution in the presence and absence of aluminum. Da ta obtained herewith allowed for the following conclusions to be drawn: (1) plant height, root lenght and total dry weight decreased with increase of aluminum levels in the nutrient solution; (2) aluminum concentration in plant tissue increased with higher levels of aluminum in the substrate; decreases pf calcium and magnesium concentration in the dry matter in the presence of higher aluminum concentration in the nutrient solution were observed.
