The fertiliser tab is where you enter Product (a range of commercially available New Zealand fertiliser products), Organic (compost/mulch, diary factory waste, piggery effluent, or other) and Soluble fertilisers, Lime and DCD applications for the farm.
Once the suite of fertilisers used on the farm are entered, their applications can be added, edited and deleted from this tab and there are two additional functions - Merge and Split applications which provides more flexibility when managing a copied analysis where fertiliser applications need to be changed.
The green fertiliser summary section at the top of the fertiliser tab shows each fertiliser product that has been entered for the farm. The summary shows the number of applications that product has on the farm, the total kilograms applied of the product and also the total kilograms applied of each nutrient. This provides a useful summary to check against fertiliser records.
The product details can be edited by selecting the edit button at the end of the products row. It also can be deleted from here. If the fertiliser is deleted all of it's corresponding applications will also be deleted.
Add, edit and delete a fertiliser products application by selecting the name of the fertiliser product in the summary section. When selecting the name of the product all of the corresponding applications are displayed and can be edited or deleted and more can be added.
DCD reduces the amount of nitrous oxide emitted and N leached. DCD applications were added to Overseer before their use was suspended in New Zealand in 2013.
DCD can be applied up to 3 times per year.
