Magnesia Carbonica

Wilting, temperature shock, frost shock. Chlorosis, dirty yellow. Windburn, damping off. (3)

damping off, Rhizoctonia, Pythium sp., Phytophthora spp., Thielaviopsis basicola, Sclerotium rolfsii, Macrophomina phaseoli, Botrytis, aphonomyces, Fusarium, Cylindrocladium. (244)

Lack of vigour (1837)

Puny, sickly looking plants which do not thrive on acidic soils or have been given unsuitable nutrients. (3)

Vesicles, wilting, wind burn. Plant low and thin. (244)

Weak plants not thriving. (337)

Vesicles on the roots, which are too dry under the epidermis. The plants are very thirsty and wilt more in the evening when the sun sets (3)

Dried roots under epi-dermis (244)

Capillary system is engorged, its action impaired (3)

Photosynthesis is impaired, protein content is low. Yellowing of the leaves, marbling between the veins. These spots become necrotic. The appearance is similar to yellow dwarf virus symptoms. The oldest leaves are least affected, later also the younger leaves. The veins and the midrib remain green. The leaves fold backward as they die. At the back of the leaves the interveinal areas are pink. yellowing of the leaf tips and margin, leaving a dark green tongue at the leaf base. Chlorosis increases and leaf scorch sets in on the margin. Older leaves are most affected. (3)

Chlorosis in general. Impaired photosynthesis (244)

Abortion of flowers, lack of flowering, sensitivity to cold temperatures. (244)

The flowers have incomplete or no stamen (3)

Stamen immature or absent. (244)

impaired or absent fruiting (3)

Absent fruit. (244)

Nutritional deficiency or excess of lime, heavy metal poisoning. Worse in the afternoon, by temperature changes. Enhanced by a mild wind. (244)

A good tonic or fertiliser in the first phase of growth.<br> Sensitive to cold. (337)

... difficulties in nutrient absorption, excess/deficiency of Mg or Ca, intolerance to low temperatures, absence or deficiency in flowering. (1837)

Microbial efficiency was mainly decreased by Magnesium carbonicum .... (1862)

Magnesium deficiencies (337)

Recommended when the aim is to conserve organic matter and if the waste available for composting is easily decomposable (low C/N ratio). (1837)
