Fluidised fertiliser is the term used for combining and processing proven fertiliser products into a form that is more evenly distributed and provide the plant with both foliar and root feeding. After processing extremely small amounts of liquid (water or liquid nutrients) are added to moisten the product for optimum foliar and root uptake, eliminate dust and targeted application. A smart way to use fertiliser!
The energy available for use by ruminant animals from feeds such as pasture. ME is expressed as MJ (megajoules). The requirements of animals is given in ME as can the feeding value of pasture.
From an agronomic efficiency perspective, lime should be fine – meaning minus 100 microns. Lime has been typically sold and applied in much coarser form simply because of spreading, dust and safety issues. Infrequent heavy applications of coarse ‘aglime’ were more convenient for solid application, but lead to a zig-zag effect on soil pH, especially in the critical 50-100mm depth, which greatly increases the risk of aluminum toxicity. Superfine lime (below 40 microns) is extremely expensive to produce, and confers no agronomic advantages over fine lime.
Futurespread uses 100 micron fine lime which is relatively inexpensive, yet fine enough to rapidly correct soil acidity and aluminum toxicity, and stimulate soil microbiological activity and organic matter turnover.
The ‘base’ N content is present as DAP. Additional N in higher N-content fluidised products is incorporated as fine urea, incorporating urease inhibitor. For an organic source we use Moana 15%N. Fluidised urea containing urease inhibitor is vastly more efficient (two and a half times!) than granular urea. This is because fluidised urea, unlike other forms of N, can be taken up directly through the leaves, for greater plant growth efficiency. However, a urease inhibitor must be present to prevent urea being volatilized directly from the leaves before uptake.
A urease inhibitor, temporarily blocks (inhibits) the action of the urease enzyme, and in so doing minimises volatilisation for 7 - 14 days, the critical period for volatisation losses after application.
Volatilisation is gaseous losses of N (nitrogen) to the atmosphere and can occur when the urea reacts with the soil moisture and breaks down leaving free ammonia (NH3) present at the soil surface. The enzyme urease, which is produced by denitrifying bacteria, facilitates the reaction. Research has shown that urea fertilisers can lose up to 30 percent or more of their N if not incorporated into the soil solution within 72 hours.
