The Better Fertiliser Decisions for Crop Nutrition Fact Sheet states that inefficient or incorrect use of fertiliser can be a substantial, but somewhat hidden cost, in the cropping operation... The new fact sheets have been distributed to growers with the November-December issue of GRDC's Ground Cover magazine and can also be viewed and downloaded via www.grdc.com.au/GRDC-FS-BFDCN and www.grdc.com.au/GRDC-FS-CropNutrition-Micronutrients ... Caption: The Grains Research and Development Corporation (GRDC) has released two new fact sheets to enhance grain growers' understanding of crop nutrition...

Growers are advised to test their soils ahead of sowing in 2016 to determine whether an opportunity exists to adjust fertiliser inputs, especially phosphorus (P)... Dr Rob Norton from the International Plant Nutrition Institute says that in non-calcareous soils, less of the P applied in a dry year will be immobilised than in a normal year... "The best way to find out if P is running down on a farm is to soil test and then assess if the program needs to build or rebuild fertility using P rates above removal, or if at maintenance, use P rates around long-term removal," Dr Norton said...

Manures prove their worth in a fertiliser program.. Manures can be a cost effective means of supplementing traditional in-organic fertilisers to help replace nutrients such asnitrogen (N) and phosphorus (P) which are extracted from the soil during a crop's growth cycle and removed from the paddock in grain... Manures from beef cattle feedlots and poultry farms are increasingly being used to supplement traditional in-organic fertilisers in helping replace nutrients such as nitrogen (N) and phosphorus (P) which are extracted from the soil during a crop's growth cycle and removed from the paddock in grain...

If growers reduce P rates at seeding then, unless it replaces what is removed, soil test values will decline, according to IPNI's Dr Rob Norton... Dr Norton says growers spend from $50 to $100 per hectare on P every year, which is a big investment when they do not know what the result is going to be at the end of the season... "Shallow samples over-estimate soil test values and deeper samples underestimate the true value representative 10cm deep samples are critical to interpret the current soil P tests...
