Phosphorun plus

Phosphorus (P) is an essential element in a multitude of functions in plant growth and metabolism, including cell division, photosynthesis, breakdown of sugars, energy conversion, etc. Most agricultural soils have large reserves of phosphate, a considerable part of which has accumulated due to the regular application of P fertilizers by farmers. However, most phosphate reserves could rapidly be 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 acidic soils, and by calcium in alkaline soils. The introduction of efficient phosphorus solubilizing bacteria (PSB) and plant growth-promoting rhizobacteria (PGPR) is a practical strategy to overcome the problem of P availability in agricultural soils.

Phosphorun plus is a new biofertilizer that is produced as a granular formulation and is characterized by the simultaneous presence of PSB and PGPR, mineral phosphate, sulfur, and organic matters. This product is applicable in any type of agricultural soil, especially those suffering from phosphorus deficiency or unavailability for fruit trees, field and greenhouse crops, vegetables and ornamental plants, etc. PSBs are a group of rhizosphere microorganisms that convert non-absorbable phosphate into absorbable form by biochemical activities in the soil and provide absorbable phosphate to the plant. PGPRs also play an important role to improve plant growth and health and inducing resistance to biotic and abiotic stresses by producing a group of phytohormones, phosphate solubilizing enzymes, siderophores, antibiotics, hydrolyzing enzymes, and antifungal metabolites.

  • In addition, providing plant's nutritional needs causes the dissolution of insoluble phosphate and enhances nutrient uptake by plants.
  • Increases crop yields in fields and fruit orchards
  • The best alternative to chemical phosphorus fertilizers
  • Possibility of organic crop production, free of chemical residues
  • Reduction of environmental pollution caused by chemical phosphorus fertilizers
  • Easy to apply by hand or with a machine similar to conventional chemical phosphorus fertilizers

Fruit and ornamental trees

For fruit and ornamental trees, Phosphorun+ can be used during winter fertilization. An average dose of 0.5-1 kg Phosphorun+ is recommended for each tree. As an easy way, use a hand or mechanical auger to dig a series of small holes (40-50 cm in-depth and at least 50 cm apart) under the tree canopy. Mix the fertilizer with a proper amount of manure or humus compost and pour the mixture into holes.

Field crops

Phosphorun+ can be used at the time of sowing or ploughing for all types of field and greenhouse crops, and vegetables. Application dose can be determined according to the phosphorus content in the soil, which is evidenced through soil analysis (see Table below). An average dose of 75 kg/ha is recommended, where soil tests are not present.

If soil content is higher than 20 ppm/kg, use the other biofertilizer, Phosphate BehRoshd, as seed inoculation (1-4 liter for 100 kg seeds according to type and size of seeds) or along with irrigation (3-4 L/ha).
