DIRECTIONS FOR USE
APPLICATION RATES are based on incorporating 0.1% Broadleaf P4 granules on a weight to weight basis into soil media. This rate has been found to produce practical, optimum cost/benefit ratios over a wide range of crops and growing conditions.
The rate may be varied to suit local conditions and/or specific requirements, but for most conditions we do not recommend application of less than 0.05% or greater than 0.2%, except where soil and/or irrigation water salinity exceeds 4500ppm. In such high salinity, the application rate may be increased to 0.4%, especially when evapotranspiration rates are also very high.
BARE ROOT- TRANSPLANTING (ROOT DIP): Stock loss during transport to planting site can be greatly reduced by dipping roots in hydrated Broadleaf P4 root dip. Moisture equal to more than seven times the root mass can be applied by dipping the roots in an equilibrium mixture. Start by mixing six gallons of water per cup (.37 lb) of Broadleaf P4 fine. Add more water after 30 minutes if water is soft. The maximum hydration of P4 fine with no free water (equilibrium) will be achieved between 6 to 10 gallons of tap water per cup of P4 fine, depending on water hardness.
Root dip is not intended to replace the regular use of P4 standard grade in backfill during transplanting.
CONTAINER PRODUCTION: When added to potting soil at recommended rates, Broadleaf P4 will provide approximately three times the available water and increase the volume (bulking) of the mix by up to 20%. Because water is "containerized" in the P4, water logging will not occur. After cutting is rooted or plant is established, harden off by drying soil to drive roots into the P4 gel. Within 10 to 15 days, plant roots will draw moisture and nutrients directly from the P4 gel. Under proper water management, Broadleaf P4 can reduce leaching. Fertilization will therefore have to be reduced. The number of containers yielded per cubic yard below include the approximately 20% increased bulking of planting mix due to the hydrated P4.

PER CUBIC YARD
BULK MIXING OF CONTAINER MEDIA
One gallon of potting soil
Five gallons of potting soil
One cubic foot of potting soil
Directions for mixing potting media: Measure out media, apply recommended amount of P4, then mix thoroughly Alternate method: Prehydrate P4 and mix are 1 part P4 gel to 4 parts soil by volume.
General Mixing Guide for Open Beds, etc.: Mix P4 dry thoroughly throughout potting media or open bed at the rate of 1 oz. per cubic ft. of media or 2 lbs. per cubic yd. of open bed. Incorporate to a minimum depth of 4" to 6".
TRANSPLANTING: Broadleaf P4 can virtually eliminate transplanting shock by "containerizing" water in the root zone and eliminating stress from both over and under watering. If directions are followed, P4 will more than triple the water available within the root zone in normal soils. After plant is established harden off by drying soil and driving the roots into P4. After 10-15 days, the plant's roots will draw moisture and nutrients directly from the P4 gel. Under proper water management, Broadleaf P4 can reduce leaching. Fertilization may therefore have to be reduced.
For all container stock up through 10 gal. size, excavate hole twice the diameter and 1.5 times the depth of the container holding the transplant. For containers larger than 10 gal. size. restrict the depth to 1.25 times the depth of the container holding the transplant material. Backfill below and around the plant with media that has been amended with P4 at the following recommended rates according to container size being used. Multiply volumes given by number of each plant size being transplanted to obtain total volume of media.
Designations given for container sizes such as 6 in., 1 gal., 5 gal., etc. are terminologies used by the potting industry. Volumes can vary as much as 25% from the true U.S. gallon capacities.

BOX SIZE-VOLUME INFORMATION
TURF SODDING AND GRASS SEEDING: Broadleaf P4 provides the perfect balance between water retention and aeration porosity, promoting strong, extensive root systems to support a hard-working turf. The resilient quality of the polymer will help to prevent compaction and maintain a permanently well-structured soil. It will also allow better penetration of rain or irrigation water, drawing roots down to a greater depth for better survival and reduced watering needs, while reducing the need for thatching and aerating.
Recommendations are based off an average application rate of 7 pounds of P4 per inch of incorporated depth, which will provide an average additional increase in moisture holding of 1/4 inch per inch of incorporation. We recommend a minimum rate of 14 pounds per 1,000 square feet, incorporated a minimum of 3 inches deep. The maximum recommended rate is 30 pounds per 1,000 square feet incorporated at least 6 inches deep. The range of 14 -30 pounds will provide an additional one half to 2.5 inches of water holding capacity. Water well and allow to drain before seeding or sodding. If P4 is applied within the specified ranges, a firm playing surface can be achieved and maintained.
Recommended rate is 5-7 lbs. per 1000 square feet applied with spreader.
Hanging Baskets: Use hydrated or dry per instructions. P4 will significantly reduce the chronic problem of basket dry-out.
Tree/Shrub Transplanting: Dig planting pocket for the tree/shrub twice the width and 1.5 times the height of the plant container or root ball. Add P4 at the following rate per size of container or root ball.
Plant container/ Root ball size
Quantity P4 dry
1 round tablespoon
1/4 level cup
1/4 level cup
1/2 level cup
1 heaping cup
Mix 1/2 the recomrnended amount of P4 in the bottom of the planting pocket. The remaining quantity of P4 should be mixed into the backfill surrounding the root ball.
Seed Germination: Mix 3 pounds dry granules per 100 square feet of bedding area into seed bed and water well prior to sowing.
