Agricultural grade Dolomite

SPARKGUYS has our own mines of dolomite and calcite. We carefully segregate the quality of agricultural grade dolomite stones and making various size of powder from our milling factory.

Character of Agricultural grade dolomite powder

Agriculture grade dolomite used for soil neutralization/conditioner to correct acidity. It also finds use as filler in fertilizers. The main ingredient is calcium carbonate, it helps to increase the pH of acidic soils and it provides a good source of calcium for plant. It improves the water penetration for acidic soil. It also contains MgCO3 for triggering fast growth of plants.

SPARKGUYS has our own factory to manufacturing and supplying both domestic and exporting wide range of agricultural grade dolomite powder, which is used in various uses.

How agricultural grade dolomite helps for plants

  • Agricultural grade Dolomite powder used primarily to control acidity(pH) in soils by making them more basic(alkaline).
  • Fertilizers and herbicides can then work efficiently, and plants can more readily absorb the nutrients that help them grow.
  • CaCO3 reacts strongly to acid in the soils, such as sulfuric acid. This reaction forms water, carbon dioxide, and calcium or magnesium salts, thus creating a soil that is less acidic and more productive.
  • The composition of these carbonates includes a low percentage(approximately 3%) of silica, aluminum and iron compounds, as well as trace elements such as strontium, sulfur, and zinc, which contribute to vigorous plant growth.
  • Higher mesh (smaller particles) has greater surface area to contact and react with soil particles than larger particles in the same amount (mass) of dolomite powder. To achieve a fine particle size, crushed agricultural grade dolomite is sieved through a series of screens until the required fineness is reached.
  • Agricultural grade dolomite also neutralizes soil pH and cuts fertilizer costs by making fertilizer more available to plant roots, so less fertilizer is needed. Fertilizers that contain nitrogen, phosphorous, potassium, and other essential nutrients are more effective in slightly acidic to neutral soils.
  • Agricultural grade dolomite boots the performance of certain herbicides. As with fertilizer, modern herbicides are most effective when soil pH is slightly acidic (pH of 6.5) to neutral (pH of 7.0). When soils are more acidic, herbicides attach to soil particles, reducing their ability to control weed growth.
  • Agricultural grade dolomite improves the chemical, biological, and physical conditions of the soil. Water infiltration, drainage, and the healthy growth of beneficial microorganisms are improved by the proper application of dolomite powder, which is a cut down on the amount of fertilizer and herbicides needed and the amount of agricultural runoff produced from them. Dolomite powder can also correct toxic levels of aluminum and manganese that are sometimes found in acidic soils.

Soil neutralization

  • Neutralization of soil is necessary in order to promote plant growth. The ability of plants to take nutrients as calcium, magnesium and other minerals from the soil into their roots is affected by the pH content of the surrounding soil particles.
  • In the liming process, agricultural grade dolomite-calcium carbonate (CaCO3) that may also contain magnesium carbonate (MgCO3) neutralizes acid in the soil and provides nutrients to promote plant growth.
  • Since liming can stimulate plant growth, it is important to also fertilize limed soil. This insures that all of the nutrients used by the plants for growth are maintained in the soil for the following year's growth.
  • Soils may also become too basic, or alkaline, especially in areas where there is little precipitation. Substances that can act as acids such as calcium sulfate, also called gypsum (CaSO4), and sulfur (S2) can be applied to the soil for neutralization.

How easy to identified alkaline soil

  • Soil ph level that is higher than 7 that is called alkaline. bellow 7 ph means that contains acidity.
  • High alkalinity also the problem for soil. if more alkalinity contains, we needs to reduce the ph level of soil.
