the magnesium in the preparation is present in the ideal form for the plant, as the nitrate nitrogen helps the uptake of magnesium. Therefore, to achieve the same effect, MAGNISAL requires 30-50% less than magnesium sulphate active substances. It can be used primarily to prevent the onset of magnesium deficiency symptoms or to treat those already present. It is particularly indicated for use in the treatment of It is an excellent control of truss stalk paralysis! The advantages of using MAGNISAL are well validated where: - a rapid recovery of magnesium deficient plants is desired, - nutrient uptake is inhibited due to low soil temperature, soil stagnation, high soil water, over-watering or root damage, - foliar fertilization is used to directly feed the plant to avoid weed infestation, - the plant has a higher requirement for magnesium for physiological reasons. Magnesium deficiencies may be expected and MAGNISAL is therefore strongly recommended: - in sandy soils with low Mg content, in case of frequent irrigation, - when growing Mg-requiring crops (sunflower, rape, cucumber, melon, potato, tobacco, tomato, pepper), - in case of high doses of ammonia or potassium fertilisation, - in calcareous soils or after liming.
