Frequently Asked Questions

Vickery Bros has put together some of our most asked questions by customers for your benifit but if you cant find the one your after contact us to answer your questions.

What is fertiliser?

Fertiliser is a product that combines the nutrients that plants need to grow - nitrogen, phosphorus, and potassium. Think of it as plant food.

What is phosphorus?

Phosphorus used in fertilisers comes from the fossilized remains of ancient marine life found in rock deposits in the U.S. and other parts of the world, or from plant and animal materials.

Phosphorus helps plant health, density, and root growth.   Phosphorus is the plant world's equivalent of carbohydrates - it provides the energy that a plant needs to grow. 

What is soil testing and why should I care?

Soil testing means sending a sample of your soil to a laboratory to learn what levels of nutrients currently exist in your soil.  The test results also provide recommendations on what your soil needs (in terms of pH, phosphorus, and potassium) to be healthy.


How often should I test my soil

Depending on your production system and stocking rate, you should test your soil every 3-4 years.

Generally to get a good indication of what is happening an average of a whole paddock is sampled and analysed. If you are going to treat land classes and soil type differently though grazing and fertiliser management, then these areas need to be tested separately.

For example; if you are going to fence off the top of the hill and section it from the lower slopes and flats, you should be testing them differently as they will carry different stocking rates.

If more intense fertiliser applications and stocking rates are applied to the paddock then it should be tested every 2-3 years.


What is Agrotain and why do we use it?

Agrotain is a coating applied to urea that reduces Nitrogen (N) losses from volatilisation.

What is volatilisation?

Volatilisation occurs when urea is converted to ammonia gas, a process which takes place in the first 48 hours after application.  So conditions during that first 48 hours are critical in terms of the amount of N lost to the atmosphere.

How much Nitrogen is lost?

Losses of N between 14 to 30% are not uncommon during the drier months.  These losses are less through winter as rainfall events and soil moisture levels increase.  However there are still losses in this period, particularly if canopy cover is less than optimal and wind speeds are high.

What does Agrotain cost?

At today’s urea price it equates to around 10% more than straight Urea.  Therefore if the potential loss to volatilisation is greater than 10% you are well in front.  Agrotain does not alter the N % of urea (46%).

When should I use Agrotain?

Spring, Summer and Autumn is the simple answer.  But in reality it ought to be used at any time of year when conditions prevail that could make urea application risky in terms of volatilisation.  September, October & November are all months where we see periods of warm dry weather that make us nervous about applying and potentially losing N.  Agrotain coating onto urea at this time of year will reduce these risks.  Autumn and early winter can also give us cause for concern when applying urea to crops and pastures as rainfall can be intermittent.  Research from overseas also indicates Agrotain coated urea can enhance N uptake at soil temperatures of minus 5 degrees.
