Pacific Fertiliser Emerge Phosphate Fertiliser blend (11-18-0-10) provides a high level of phosphorous and sulphur (similar to double super), but with the added advantage of a some nitrogen.

PacFert’s Goldphosphate equivalent fertiliser blend is competitively priced and available from all major Australian ports.

General addition rates for pasture applications are  60 –  125 kg/ha.

The products is suited to belt spreader and aerial applications.

Why Does Chicken Manure Perform better with Gypsum blends

When gypsum is blended into a compost windrow or mixed in a manure pile before or after spreading, the sulfate salt naturally attaches to the ammonia molecules, forming ammonium sulfate – effectively trapping it in another stable form and preventing ammonia volatilization.

Test results have proven a reduction of ammonia loss can be achieved with the presence of gypsum or sulfate. Compared to other products gypsum has more sulfate available so it can trap more ammonium over superphosphate and triple superphosphate. The more product blended in the mix, the more ammonia was trapped.

Some chicken manure results show that gypsum can absorb moisture from chicken manure, thereby increasing matric and osmotic stress, which led to a 38% – 71 % decrease in urea-degrading bacteria (UDB). In the chicken broiler-rearing houses, ammonia (NH3) volatilization from broiler litter can impair bird health during the rearing process, decrease the fertiliser value of final chicken litter, and is bad for the environment. As urea was hydrolyzed in gypsum-amended manure blends, additional CaCO3 present in the products can precipitate and buffer against large increases in pH that accompany urea hydrolysis.

For soils high in sodium like those in the areas with irrigation water containing high salt contents (TDS), growing quality produce and crops can be a challenge.

There are a few common methods to treat soils with high sodium contents;

• Rain events or irrigation with low TDS water to leach the salts out of the root zone and down through the soil profile (both can be hard to organise).
• Gypsum Application – Gypsum improves soil structure by displacing sodium (and magnesium) on the surface of clay particles with calcium. Gypsum can be applied as broadcast, through foliar or fertigation applications.
• Humate application – Salt is composed of a metal ion bonded with chlorine. Depending on soil moisture, salt will occur either in solution or as a crystal within the soil. If chelation techniques can capture the metal ions, releasing the chlorine, the salt molecule will be broken. It is generally recognised organic acids common to soil humus are excellent chelating agents. Humic acid can be applied as broadcast, through foliar or fertigation applications.
