Agricultural Magnesium fertilizer

Magnesium Oxide for Agricultural Magnesium fertilizer

Tibet Mag provides magnesium oxide for use in agricultural applications.

TIBETAMAG is a high purity agricultural grade magnesium oxide that provides a source of magnesium as a nutrient. magnesium oxide is useful in correcting magnesium deficiencies in a wide variety of soils and crops.

Magnesium Oxide as a Crop Nutrient Supplement

Seventeen nutrients have been identified as essential for plant growth.  Without these nutrients, plants cannot complete their life cycles.  Magnesium (Mg) is considered a “macronutrient” – those of the 17 nutrients required in relatively large quantities.

Soils where large amounts of potassium have been applied, repeatedly, are low in magnesium.  High application of potassium or ammonium fertilizers often heightens magnesium deficiency. High cations concentration interferes with Mg uptake. This interference generally does not occur where soils contain more exchangeable Mg than exchangeable K.

One symptom of magnesium deficiency is low-yielding crops, where plants set fewer pods, containing fewer seeds, hence reduced grain yields. magnesium oxide is useful in correcting magnesium deficiencies in a wide variety of soils and crops.

Soil acidification is a natural process that is increased by normal production practices, particularly the use of nitrogen fertilizer and manure.  High levels of soil acidity can reduce root growth, reduce nutrient availability, and affect crop protectant activity.  Water-soluble magnesium is developed in the soil as magnesium oxide is broken down by the action of soil acids to furnish available magnesium, and neutralize acidity.

TIBETAMAG magnesium oxide offers a good nutrient source for blending of mixed fertilizers due to its high concentration of magnesium.

The Role of Magnesium fertilizer in Plant Life

Just like people, plants need food to live.

They make food through photosynthesis, a process that requires water, carbon dioxide and sunlight.

Photosynthesis occurs in chlorophyll, a green pigment that contains magnesium — if plants don’t have this nutrient, they cannot make the food they need to survive.

Magnesium fertilizer also assists with the following functions:

  • Cell division
  • Protein formation
  • Plant respiration
  • Enzyme activation
  • Metabolism

Without magnesium fertilizer, plants cannot carry out many essential processes.

Magnesium fertilizer deficiency is a frequently occurring limiting factor for crop production due to low levels of exchangeable Mg (ex-Mg) in acidic soil, which negatively affects sustainability of agriculture development.

How Mg fertilization affects crop yield and subsequent physiological outcomes in different crop species, as well as agronomic efficiencies of Mg fertilizers, under varying soil conditions remain particular interesting questions to be addressed. A meta-analysis was performed with 570 paired observations retrieved from 99 field research articles to compare effects of Mg fertilization on crop production and corresponding agronomic efficiencies in different production systems under varying soil conditions.

The mean value of yield increase and agronomic efficiency derived from Mg application was 8.5% and 34.4 kg kg-1 respectively, when combining all yield measurements together, regardless of the crop type, soil condition, and other factors. Under severe Mg deficiency (ex-Mg < 60 mg kg-1), yield increased up to 9.4%, nearly two folds of yield gain (4.9%) in the soil containing more than 120 mg kg-1 ex-Mg. The effects of Mg fertilization on yield was 11.3% when soil pH was lower than 6.5. The agronomic efficiency of Magnesium fertilizers was negatively correlated with application levels of Mg, with 38.3 kg kg-1 at lower MgO levels (0–50 kg ha-1) and 32.6 kg kg-1 at higher MgO levels (50–100 kg ha-1). Clear interactions existed between soil ex-Mg, pH, and types and amount of Mg fertilizers in terms of crop yield increase. With Mg supplementation, Mg accumulation in the leaf tissues increased by 34.3% on average; and concentrations of sugar in edible organs were 5.5% higher compared to non-Mg supplemented treatments. Our analysis corroborated that Mg fertilization enhances crop performance by improving yield or resulting in favorable physiological outcomes, providing great potentials for integrated Mg management for higher crop yield and quality.
