Biophosphate Biorun

Phosphorus (P) is a key element with a plethora of functions in plant growth and metabolism, including cell division, photosynthesis, breakdown of sugars, energy transfer, etc. Most agricultural soils contain large reserves of phosphorus, a considerable part of which has accumulated due to regular application of P fertilizers by farmers. However, most of these phosphorus reserves are rapidly immobilized, fixed, and so, become unavailable to plants. Depending on soil acidity (pH), the process of P fixation occurs by free oxides and hydroxides of aluminum and Iron in acid soils, and by calcium in alkaline soils. Introduction of efficient phosphorus solubilizing bacteria (PSB) is a practical strategy to overcome the problem of P availability in agricultural soils.

Biophosphate Biorun is a new P biofertilizer that is produced as granular formulation by the Nature Biotechnology Company. Biophosphate Biorun is characterized by simultaneous presence of phosphorus solubilizing bacteria (5 × 104 CFU per gram), organic matters (8%), and mineral phosphorus (20% based on P2O5). This product is applicable in any type of agricultural soils, especially those suffering from phosphorus deficiency or unavailability.

  • Contributing towards reduction of the use of chemical P fertilizers in agriculture.
  • Preventing phosphorus fixation and insoluble P accumulation in soils.
  • Improving soil structure and biodiversity with respect to biological activity of bacteria.

Fruit and ornamental trees

For fruit and ornamental trees, Biophosphate Biorun can be used during winter fertilization and in combination with other types of fertilizers such as manure, humus, chemicals, humic acid, etc. An average dose of 1-2 kg fertilizer is recommended for each tree. As an easy way, use a hand or mechanical auger to dig a series of small holes (20 cm in depth and at least 50 cm apart) under the tree canopy. Mix the fertilizer with appropriate volume of composted manure or humus and pour the mixture in holes. Fill the hole with soil and water the garden.

Field crops

Biophosphate Biorun can be used at the time of sowing or ploughing for all types of field and greenhouse crops, and vegetables. The dose of application can be determined according to phosphorus content of soil, which is evidenced through soil analysis (see Table below). Where soil analysis is not present, an average dose of 100 kg per hectare is recommended. Fertilization can be performed either by broadcasting, where the fertilizer is uniformly distributed throughout the field before ploughing, or as band placement, where the fertilizer is applied in continuous bands near (usually below) the seeds, such that the growing roots will easily reach it.
