To answer to the food demand, all farmers try to maximize the crops they can cultivate on their land. For decades, farmers have used fertilizers to increase their crop yields. With the green revolution, more environmentally friendly but still effective biofertilizers have been introduces and they are widely used all over the world, especially in areas where the usage of synthetic fertilizers has ruined the natural nutrient levels of the soil Biofertilizers are a way to increase crop production by naturally optimizing the nitrogen and phosphorus levels of the soil and by enriching the compost waste used as a natural fertilizer.

What Are Biofertilizers
Biofertilizers are live formulates of microorganisms that are ready to be used and improve the quality and the health of the soil and the plant species by increasing the nutrient availability for the soil, seeds and roots. Biofertilizers naturally activate the microorganisms found in the soil restoring the soil's natural fertility and protecting it against drought and soil diseases and therefore stimulate plant growth.
Synthetic fertilizers are made from nonrenewable fossil fuel resources, create nutrient imbalance in the soil and are often used in excessive amounts. Soils and plants are becoming dependent on the synthetic fertilizers, which increases their negative effects. Biofertilizers are a natural way to get the benefits of synthetic fertilizers without risking the quality of soil health and crop products. Using biofertilizers can increase the crop yield by 20 or 30 percent. In addition, biofertilizers are cost effective when compared to synthetic fertilizers.
Nitrogen biofertilizers help to correct the nitrogen levels of the soil. Nitrogen is a limiting factor for plant growth because plants need a certain amount of nitrogen in the soil to thrive. Different biofertilizers have the optimum effect for different soils, so the cultivated crop determines what type of nitrogen biofertilizer should be used. Use Rhizobium for legume crops, Azotobacter or Azospirillum for non-legume crops, Acetobacter for sugarcane and blue-green algae and Azolla for low land paddies used to grow rice.
Just like nitrogen, phosphorus is also a limiting factor for plant growth. Phosphorus biofertilizers help the soil to reach its optimum level of phosphorus and correct the phosphorus levels of the soil. Unlike nitrogen biofertilizers, the usage of phosphorus biofertilizers is not dependent on the crops cultivated on the soil. You can use Phosphatika for all crops with Rhizobium, Azotobacter, Azospirillum and Acetobacter.
You can also use biofertilizers to enrich your compost and the bacterial processes breaking down the compost waste. Suitable biofertilizers for compost use are Cellulolytic fungal culture and Phosphotika and Azotobacter cultures.
