Kala Sona

MBF Pioneer in manufacturing and marketing Humic Acids, having production capacity up to 50000 MT per year. MBF is only company in India that manufactures 100% natural Humic acid.

MBF Humic Acid marketed as brand name MBF Kala Sona.

Kala sona is black fine powder and has 95% solubility. As a result, soil treated with MBF Kala Sona secures qualitative and quantitative increase in yield and reduce material and labour cost. MBF has extensive product line of the highest quality which has been designed to fulfill the demands of healthy community. One kilogram of Kala Sona (Concentrated Powder) is equivalent to about 1 Metric Ton of manure. Kala Sona chelates nutrient compounds, especially iron, suitable for plant utilization. Thus, the nutrient supply of plants is optimized.

Use of Kala Sona increases up to 70% in yield, accompanied by a reduction up to 30% in the use of fertilizers and pesticides, as well as better and healthier growth of greengrass, ornamental, agricultural crops and woods can be attaines with the regular application of first-quality humic acids.


Soil application Dosage

  • For 3 month old crop: Apply 1 kg per acre.
  • For above 6 month crop : Apply 2 kg per acre
  • For sugarcane: Apply 2 kg per acre.


  • 2 Bags of Urea/DAP/K20 + 1 kg of Kala Sona. (Equalizes 5 Bags of Urea/DAP/K20.) If you are using Kala Sona, reduce chemical fertilizer dose.
  • Applicable for all types of crops : Sugarcane, Cereals, Pulses, Oil Seeds, Fibrous Plants, Vegetables, Fruits, Flowers, Spices, Cash crops, Plantation & Medicinal crops. 100% water soluble best for fertigation, drip & foliar spray.


Physical Benefits

Kala Sona physically modify the structure of the soil

  • Improve the structure of soil; Prevents high water and nutrient losses in light, sandy soil. Simultaneously convert them into fruitful soil by way of decomposition. In heavy and compact soil, aeration of soil and water retention are improved; cultivation measures are facilitated.
  • Prevent soil cracking, surface water runoff and soil erosion by increasing the ability of colloids to combine.
  • Help the soil to loosen and thus increase aeration of soil as well as soil workability
  • Increse water holding capacity of soil and thus helps to resist drought.
  • Darken the color of soil and thus helps in absorption of the sun energy.

Chemical Benefits

Kala Sona chemically changes the fixation properties of the soil.

  • Neutralize both acid and alkaline soil; regulate the pH-value of soil.
  • Improve and optimize the uptake of nutrients and water by plants.
  • Increase buffering properties of soil.
  • Act as natural chelator for metal ions under alkaline conditions and promote their uptake by the roots.
  • Rich in both organic and mineral substance essential to plant growth.
  • Retain water soluble inorganic fertilizers in the root zones and reduce their leaching.
  • Possess extremely high cation-exchange capacities.
  • Promote the conversion of nutrient elements (N,P,K,+Fe,Zn and other trace elements) into forms available to plants.
  • Reduce the reaction of phosphorus with Ca, Fe, Mg, and Al liberal it into a form that is available and beneficial to plants. The productivity of particularly mineral fertilizers is increased considerably.
  • Liberate carbon dioxide from soil calcium carbonate and enable its use in photosynthesis.
  • Help to eliminate chlorosis due to iron deficiency in plants.
  • Reduce the availability of toxic substance in soil.

Biological Benefits

Kala Sona Biologically stimulates the plants and the activities of micro-organism.

  • Stimulate plant enzymes and increase their production.
  • Act as an organic catalyst in many biological processes.
  • Stimulate growth and proliferation of desirable micro-organism in soil.
  • Enhance plants natural resistance against disease and pest.
  • Stimulates root growth, especially vertically and enable better uptake of nutrients.
  • Increases root respiration and root formation.
  • Promote the development of chlorophyll, sugars and Amino Acids in plants and aid in photosynthesis.
  • Increase vitamin and mineral content of plants.
  • Thicken the cell walls in fruits and prolong the storing and shelf time.
  • Increase germination and viability of seeds.
  • Stimulate plant growth (higher biomass production) by accelerating cell division, increasing the rate of development in root system and increasing the yield of dry matter.
  • Increase the quality of yield; improve their physical appearance and nutritional value.

Pesticide, Herbicide and Fungicide charged soil

Kala Sona increase the efficiency of pesticides, fungicides and herbicides and immobilize their harmful residues.


Available In: 100gm, 250gm, 500gm, 1Kg, 5Kg, 20Kg.

Kala Sona also available in 25kg and 50kg drum for loose bulk order.

Mode of Action

Humus has a profound effect on the structure of many soils. Humus plays an indirect role in soil through its effect on the uptake of micronutrients by plants and the performance of herbicides and other agricultural chemicals.
