Implications of 2018 drought and frosts for nutrient management in 2019?

2018 provided many challenges for grain growers, with mother nature dealing out drought and frost and everything in between across Australia’s grain growing regions.  In light of these seasonal conditions and with harvest 2018 nearly over for many, what plans should you be making for your 2019 crop nutrition program? […]

Can you come to a BFDC workshop this week?

The Better Fertiliser Decisions for Cropping (BFDC) program wants feedback. How have we done so far, and how can we improve? If you can make it, there are two sessions this week: Date: Thursday 29th November 2018 Time: 10:30 AM to 12:30 PM followed by lunch Venue: Auditorium, Longerenong College, […]

Which soil problem should you fix first? Ask ROSA

Western Australian growers with multiple soil constraints can check which one is costing them the most. The WA tool, Ranking Options for Soil Amelioration (ROSA), assesses which soil management options will give the biggest return on investment. WA croppers lose $4.3 billion each year from soil constraints. Most losses are […]

BFDC III webinar – a chance to have your say on its future

Inspecting biomass produced in a biserrula pasture phase

Please register for a webinar on the Better Fertiliser Decisions for Cropping database and have your say on its future. – Nov 15, 2018 2:00 PM AEDT The Better Fertiliser Decisions in Cropping (BFDC) database and data interrogator has been developed over the last 7 years with training and support […]

How to adjust phosphorus after a dry year

A poor or failed crop last season will affect nutrient budgets this season. Cereal hay removes about 1–2 kg of phosphorus (P) per tonne of dry matter. Canola removes about 3 kg of P per tonne (see Table 1). Table 1. Comparison of nutrients removed in grain, straw, canola hay, […]

Chicken manure improves sandy soils

Chicken manure is helping to ameliorate sandy soils on South Australia’s Yorke Peninsula. Trial results over three years indicate that high-rate surface applications combined with deep ripping are delivering the highest marginal returns. Positive results The marginal returns from applying chicken litter (or a comparable, inorganic fertiliser), and deep ripping, […]

Make better crop nutrition decisions with these tools

There are a variety of free and paid support tools to help make crop nutrition decisions. Please note this is not a complete list. Check out Climate Kelpie for more decision support tools. Free Tools SoilMapp collates data from national soil databases (ASRIS and ApSoil). View maps, photos and satellite […]

Growing legumes? How to check their nodules

Late winter and early spring is the best time to check legume nodules. To fix nitrogen, legumes need the symbiotic soil bacteria rhizobia in their root nodules. Legumes without effective nodules will deplete soil N and can perform poorly. Lack of rhizobia causes poor nodulation. Rhizobia come from the soil […]

Legumes provide significant N in low rainfall systems

Legume break crops can provide significant fixed nitrogen (N) for subsequent cereal crops. From 2013 – 2015, Michael Moodie (Mallee Sustainable Farming) compared various legume crop productivity and N contribution in low rainfall environments. Trials were conducted in the Victorian and South Australian Mallee regions, where N is often limiting. […]

Nutrient implications for failed crops

Many growers and advisers in eastern Australia are weighing up the options for their drought-stressed and frost-damaged crops.  Is it more economical to conserve crops as hay or silage, graze them or hope to eventually harvest them? Has the generally high cost of hay cutting been fully taken into account? […]
