Polyether-Modified Polysiloxane


SOIL-JET®BSP100 is a patented soil surfactant based on polysiloxane that enhances Agricultural, Horticulture, Ornamental, Sports Turf Amenity and Forestry productivity. It benefits Growers, Farmers, Greenkeepers, and Foresters seeking improved yield, crops, turf, efficient nutrient utilisation, and sustainable soil management.
SOIL-JET® BSP100 enhances penetration and infiltration of irrigation water and rainfall into the soil profile. It also helps to reduce surface evaporation, maintain homogeneous soil moisture in the root zone and optimize plant nutrition.
SOIL-JET® BSP100 contributes to better crop health, root weight, fruit quality, and yield. Moreover, it is highly effective even at high temperatures and is environmentally friendly.
The ideal time to apply SOIL-JET®BSP100 is at the beginning of the irrigation cycle, either immediately before rainfall or before sprinkler or pivot irrigation. It can be applied alone with water or together with nutrients in fertigation systems, with a recommended dose rate of 1 L/ha, up to 2 L/ha for certain crops. Additionally, it is advisable to repeat applications with a minimum interval of 10 days, up to 6 times per growing season, irrigating between application cycles as usual.
The recommended dosage is 1 – 2 L per hectare for specific crops such as horticultural and ornamental crops, fruit trees, citrus, grapes/vineyards and turfgrass. You can apply it up to 6 times per growing season, with a minimum interval of 10 days between applications. It’s crucial to irrigate between application cycles as usual.
SOIL-JET®BSP100 can be applied either alone with water or together with nutrients in fertigation systems. This means you can mix it with synthetic fertilisers during application to enhance the efficiency of water use and nutrient uptake by plants.
Yes, SOIL-JET®BSP100 can be sprayed during the daytime or on a hot day, but it’s essential to follow safety precautions and recommendations provided on the label.
  • Reduces surface tension, runoff, soil erosion, and nutrient loss.
  • Enhances water/nutrient absorption for improved plant nourishment.
  • Facilitates water penetration and infiltration into the soil profile.
  • Reduces water evaporation, ensuring even distribution in the root zone.
  • Maintains constant humidity, promoting sustained nutrient availability.
  • Prevents water repellence in soils.
  • Dissolves nutrient deposits in irrigation tubes.
  • Increases Soil Volume; provides more space for root growth.
It’s generally recommended to avoid mixing SOIL-JET®BSP100 with chemical fungicides unless compatibility has been specifically tested and confirmed. For more information and guidance, please consult our technical team.
SOIL-JET®BSP100 primarily conditions grass to withstand environmental stresses and should be used alongside proper mineral fertilization practices.

SOIL-JET®BSP100 can positively impact turfgrass fertilization programs in several ways:

  • Enhanced Water Penetration: SOIL-JET®BSP100 improves water penetration, ensuring better nutrient delivery to turfgrass roots.
  • Reduced Evaporation: By reducing surface tension and preventing soil repellency to water, SOIL-JET®BSP100 helps maintain constant soil moisture levels, reducing water loss through evaporation and ensuring consistent nutrient availability.
  • Increased Nutrient Uptake: This enhanced water distribution improves nutrient uptake, maximizing the efficiency of fertilization programs.
  • Enhanced Nutrient Use Efficiency: SOIL-JET®BSP100 optimizes nutrient use efficiency, promoting healthier turfgrass growth and improved overall quality.
  Overall, incorporating SOIL-JET®BSP100 into turfgrass fertilization programs can help maximize the effectiveness of nutrient applications, leading to healthier, more resilient turf.

SOIL-JET®BSP100 is compatible with various irrigation systems and can be combined with synthetic fertilizers, nutrients in fertigation systems, and beneficial microorganisms applied through irrigation. 

You can typically expect to see results shortly after using SOIL-JET®BSP100, as it works to enhance water penetration, reduce evaporation, and improve nutrient uptake efficiency. However, the exact timing of visible results may vary depending on factors such as soil conditions, weather, and crop type.

SOIL-JET®BSP100 should be handled with caution, especially around pets and children, as indicated by its safety data sheet.
