Manganese is one of the essential micronutrients for plant growth, although it is often overlooked compared to macronutrients. Despite its small amount, manganese plays a crucial role in photosynthesis, cell wall formation, and defense against oxidative stress in plants. In this article, we explain what agricultural manganese is, its benefits, how to apply it effectively, and the crops that benefit most from this nutrient. In addition, we will show you some of the BH Terra manganese products that can optimize the performance of your crops.
What is agricultural manganese?
Manganese (Mn) is an essential micronutrient for plant development. Although it is only needed in small amounts, its function is vital for various biological and metabolic reactions within plants. Manganese is a key component of several enzymatic systems involved in photosynthesis, cellular respiration, and lignin synthesis, which strengthens cell walls and improves plant resistance to disease.
Although manganese is not required in large quantities, its presence is essential for plants to carry out vital processes such as chlorophyll production and regulation of nitrogen metabolism. When there is a manganese deficiency, plants may show symptoms of chlorosis (yellowing of the leaves) and retarded growth.
Benefits of Manganese in Agriculture
Manganese is crucial for plant health and development. Some of the most important benefits of agricultural manganese include:
Improves photosynthesis
Manganese is a central component of the enzyme involved in the process of photosynthesis. This enzyme helps break down water during photosynthesis, releasing oxygen and allowing plants to convert sunlight into energy. An adequate level of manganese is critical to maintaining efficient photosynthesis, resulting in better growth and increased biomass production.
Strengthens cell walls
Manganese is also important for the synthesis of lignin, a compound that strengthens plant cell walls. This helps make plants more resistant to breakage and infections caused by fungi and bacteria. A plant with a good manganese content has a greater capacity to defend itself against diseases.
Regulation of nitrogen metabolism
Manganese is involved in the activation of several enzymes involved in nitrogen metabolism. This is crucial for plant growth, as nitrogen is one of the most important nutrients for plant development. An adequate supply of manganese improves the efficiency of nitrogen use, promoting more vigorous growth.
Resistance to oxidative stress
Manganese acts as an antioxidant, protecting plants from the negative effects of oxidative stress. This stress can be caused by factors such as high temperatures, drought or the presence of heavy metals in the soil. An adequate level of manganese increases the resistance of plants to extreme weather conditions and other stress factors.
Form of application of Manganese in agriculture
Manganese can be applied in a variety of ways in agriculture, depending on the specific needs of the crop and the condition of the soil. The most common forms of application include:
Foliar application
Foliar application is one of the most effective ways to supply manganese to plants. Foliar fertilizers containing manganese are rapidly absorbed through the leaves, providing nutrients directly and efficiently. This technique is especially useful when there are obvious manganese deficiencies in plants.
Application to soil
Manganese can also be applied to the soil in the form of granular or liquid fertilizers. In manganese-deficient soils, soil application can help improve the availability of this nutrient. However, it is important not to apply too much, as too much manganese can cause toxicity in plants.
Irrigation systems
In crops using irrigation systems, manganese can also be supplied through drip irrigation or fertigation. This allows for a more uniform distribution of the nutrient along the roots and facilitates its absorption by the plants.
Crops most suitable for using manganese fertilizer
Manganese is essential for a wide variety of crops, although its importance varies depending on soil conditions and the specific needs of each species. Some of the crops that benefit most from manganese application include:
Fruit trees
Fruit trees, such as apple, pear, citrus and olive trees, benefit greatly from manganese, as this micronutrient promotes flowering and fruit formation, as well as improving the quality of the final fruit. An adequate supply of manganese improves photosynthesis and lignin synthesis, resulting in greater resistance of trees to diseases.
Cereals
Cereals such as wheat, corn and rice also require manganese for proper growth. This nutrient is essential for the formation of chlorophyll and the absorption of nitrogen, two key factors for the production of these crops.
Legumes
Legumes, such as beans, peas and alfalfa, also need manganese to ensure good growth and healthy development. Manganese improves nitrogen fixation and optimizes legume yield.
Vegetables
Leafy green vegetables, such as spinach, lettuce and chard, are particularly sensitive to manganese deficiencies, as this micronutrient is essential for photosynthesis and chlorophyll production. Ensuring an adequate supply of manganese guarantees better growth and higher production of these vegetables.
