Liquid Fertilisers: Most Common Questions Answered

What is liquid fertiliser?

 

Liquid fertilisers are a concentrated mixture of the plant’s essential nutrients that can be added to water and applied directly to soil. These products include synthetic chemicals such as nitrogen, phosphorus, potassium and iron.

Liquid fertilisers are used in large scale crop farming, particularly for non-wetting (water repellent) soil and dry sowing conditions. This liquid form offers a better chance of penetrating the soil, making nutrients immediately available to crops quicker than alternative solid fertiliser forms.

 

There are three main common ingredients used in liquid fertilisers:

 

  • Nitrogen: Nitrogen helps plants synthesise the energy they need to grow and produce high-quality fruits or seeds.

  • Potassium: Potassium helps stimulate food production as well as boosts immunity against infections and diseases in plants.

  • Phosphorous: Crops need phosphorus to grow and produce fruit. Without these nutrients, crops do not receive enough energy throughout their structure and cannot reproduce or mature properly.

  • Calcium: Plants need calcium to build a solid cell wall structure. Calcium also makes it easier for other minerals to be absorbed.

What are the different ways to apply liquid fertiliser?

Liquid fertiliser can either be applied directly to the ground or on top of leaves. Foliar applications make it more readily available but don't last as long, while ground application lasts longer and provides a better supply for plants throughout the season.

 

What are the benefits of using liquid fertiliser? 

Liquid fertiliser provides many benefits including easy application and handling. The most obvious benefit is that it can be blended with any crop protection product in a single pass for an entire season to deliver double the nutrients to your paddocks. Liquid fertilisers distribute nutrients more evenly than granular forms of fertiliser, which makes them ideal when used alongside other types of plant food add-ons such as pesticides and herbicides

 

What is the difference between liquid and solid fertilisers?

 

Speed of action

Liquid: Fast-acting, ideal for water repellent soils and dry sowing conditions. They don't need to be broken down by the soil's water which makes them more readily absorbed by roots. Ideal if fast nutrient uptake is needed!

Solid: Slowly acting. First broken down by water from the soil, which is ideal if you want a slow release of nutrient uptake.

 

Application 

  • Liquid: Fluid fertilisers are said to seep into the soil and distribute nutrients more evenly than granular fertilisers, giving crops a more consistent coating.

  • Solid: In contrast to liquid fertilisers, solid fertiliser is applied in patterns throughout the paddock that may not be uniform. The result of this application method causes less consistent results for farmers and their crops.

 

How quickly does liquid fertiliser work? 

 

It takes just a few minutes for the liquid fertiliser to be absorbed into your crops' nutrient stream. Urea based liquid fertilisers take approximately 5 days to work but environmental conditions like temperature and humidity levels can also affect how slow or fast they will work.
