What Are Agrominerals? Farming and Agrominerals

Having an understanding of the different types of agrominerals is important when planning to use them on your farm. Generally, there are five main types of agrominerals – calcium, magnesium, potash, sulfur, and phosphate. The type of agromineral you need will depend on what you intend to grow on your farm.


During the 19th century, agrominerals were introduced as a fertilizer. These are natural mineral deposits that contain recognized plant nutrients. They are often used as a soil amendment and as an alternative to chemical fertilizer.

The process of using agrominerals involves crushing rocks into “rock powder” and then putting the powder into the soil. This process is called “remineralization”. Agrominerals are used in commercial farming operations, hobbyist gardening, and for mitigation of climate change.

The main component of agrominerals is potassium. This is an essential nutrient for plant growth and development. Potassium is a naturally occurring mineral that is found in clay minerals and heavy soils. Potassium is also needed to maintain muscle and heart tissue.

The first agrominerals were used to create the soil conditions for exotic plants. However, these methods are not environmentally sustainable. In the early days, potassium was extracted from wood ashes by leaching the ashes and then evaporating the water in large iron pots.

Today, potassium-rich minerals are scarce in India. However, India has ample resources of feldspar. This mineral comprises over half of the earth’s crust. Feldspars can have different elemental compositions and polymorphic structures.

Potassium-bearing alumino-silicate minerals have been referred to as agro-minerals. These minerals have been proposed as a cheaper source of potash.

Agricultural soils are becoming depleted of potash. This has led to the increased use of chemical fertilizers. Agronomists are trying to find alternative sources of potash.


Adding calcium to your soil’s fertility program can improve your plants’ health and produce better-quality fruit. Calcium can also improve soil structure. It is a necessary nutrient for plants.

There are three main forms of calcium. Calcium ions have a double positive charge. They are able to attach to soil exchange sites and can be suspended in soil water. They also improve soil structure by improving the aggregation of soil particles. The best form of calcium for plants is soluble calcium in soil water.

Calcium plays a crucial role in the production of plant tissues, including the root, stem and leaf. It also helps to hold together the cells in the plant’s cell walls. Calcium also helps plants fight off attack from outside forces.

When calcium is present in the soil, it helps plants absorb water and improves their growth. Calcium helps to build cell walls, promotes plant uniformity, and increases the feed value of forage crops to livestock. Calcium can also be added to irrigation water. It also helps to raise the pH of the soil.

Adding calcium to your soil’s fertility plan can be beneficial if the soil is acidic. However, calcium fertilizers can be harmful if they are added to basic soils.

Calcium is not easily moved from one part of the plant to another. However, it is one of the most important minerals in production agriculture.


Despite being an alkaline metal, magnesium is essential to plants and animals alike. It plays a central role in photosynthesis, as it is the central structural element of chlorophyll, which is responsible for the removal of carbon dioxide from the air. In addition, magnesium is important in hundreds of metabolic reactions.

A magnesium deficiency can cause problems in the human body, including a wide range of health problems. In fact, magnesium is crucial for the biological activity of ATP.

Magnesium is also important for protein formation and energy transfer. It is a component of enzyme activators and chlorophyll pigments. A deficiency of any nutrient can affect the quality of your crops, and in some cases, can cause crop failure.

Magnesium is present in both soluble and insoluble forms. It is a slow-acting mineral, and therefore tends to move from the non-exchangeable to the exchangeable form over time. A magnesium deficiency will typically show up in the older leaves of the plant when the dry matter content of the leaves falls below 0.2% Mg.

One of the best ways to increase the amount of magnesium available in your soil is through the use of magnesian limestone. Lime containing magnesium is often broadcast before a crop is planted. This will increase the soil’s pH and increase the amount of Mg available.

Magnesium can also be found in manures. However, the amount varies widely. It is also available in irrigation water, which can contain substantial amounts of the mineral.


Historically, potassium and nitrogen were considered the “Big 3” macronutrients, but sulfur is now receiving its due as an essential macronutrient. Achieving sufficient sulfur supply is important for improving crop quality and yield, while maintaining the flavor of vegetables. It also protects plants from disease by inducing S-dependent resistance.

Soils have the potential to store sulfur, but most sulfur in soil is stored in organic matter. Increasing the organic matter content of the soil can increase the availability of sulfur for crops. The amount of sulfur in soil varies widely. The sulfur availability of soils also depends on factors such as soil mineralogy and organic matter content.

Sulfur is used by plants to synthesize chlorophyll, proteins, and sugars. It also plays an important role in the biological nitrogen fixation process. It can also improve the flavor of some vegetable crops.

Sulfur can be obtained from various sources, including animal manure, air, and irrigation water. The amount of sulfur in soil is dependent on the type of sulfur fertilizer applied and the amount of organic matter in the soil. In addition, the amount of sulfur removed from the soil by crops may vary from year to year.

Plants need sulfur to produce chlorophyll, proteins, and oils. The amount of sulfur required by a crop will depend on the species, yield, and soil condition. Some crops, such as alfalfa, have high sulfur requirements.

Remineralization of rocks

Traditionally, rock dust used for remineralization has been applied at high rates. This is in spite of the fact that there is little or no nitrogen content in most of these dusts.

However, the use of these dusts as soil amendments has recently been regulated in Brazil. In order to determine their effectiveness, researchers have looked at the effect of different rock dusts on soil chemical attributes such as soil pH and available potassium.

The presence of remineralizers stimulates the endogenous microbial communities of the soil, thus providing plants with nutrients. This process benefits the performance of cultivated plants. In addition, rock dusts can be applied at very low rates and have immediate benefits.

These low rates are based on the use of highly micronized fractions of the rock dust blends. This fraction is immediately available to the biologic systems and builds enzymes and amino acids.

Some rock dusts are particularly beneficial for remineralization. This includes basalt, an igneous rock that contains calcium, magnesium and iron. The use of basalt rock dust can help to promote sustainable soil remineralization. The presence of basalt rock dust has been shown to increase sugarcane yields in Mauritius.

The use of basalt rock dust for remineralization is sustainable. This type of remineralizer is harvested from mining basalt and can be used in agriculture for long-term soil building.

Unlike synthetic fertilizers, rock dusts provide a slow release of nutrients that are available for plants. They are also valued as a broad spectrum source of minerals. This means that they can reduce reliance on narrow elemental spectrum fertilizers.

Alternative sources for agrominerals

Using rock powder in the form of a fertiliser is a popular way to keep the soil from looking like a swamp. Agrominerals are a naturally occurring geological material that contain recognized plant nutrients. Originally used to mimic the soil conditions of exotic plants, the agro-mineral is now found in a variety of applications.

The process consists of crushing rocks into a powder and then sprinkling it onto the soil. There are several advantages to using agrominerals over chemical fertilizers including reduced runoff, a cleaner environment and less waste. It also provides essential plant nutrients in a form that is readily available to plants. Agrominerals are also a cheaper alternative than their chemical counterparts.

The name of the game is getting the most out of your investment. Agrominerals are best used in conjunction with conventional fertilizers to boost crop yields and improve soil health. As with other products in the fertiliser aisle, agrominerals should be used in moderation to avoid toxicity in the soil. In fact, in some areas of the world, the use of agrominerals is encouraged in order to boost soil quality and crop yields.

The most important agro-minerals to use are potassium, nitrogen and phosphorus. The latter two elements are often depleted in soil layers due to agricultural practices, with the results primarily visible as a lack of green growth and crop yields. In the past, the only way to combat these deficiencies was to use chemical fertilizers. However, this method has its drawbacks, including the fact that it may contaminate the groundwater.
