slugs are a major pest of crops globally, and have emerged as a serious pest for australian grain growers in recent decades... Slugs will eat all parts of a crop plant seedlings are the most vulnerable and this is the time when major economic losses can occur... Current research cultivation is effective in reducing slug is investigating this further, but preliminary numbers as it destroys their habitat results suggest that a minimum of 250,000 this is not an option in zero-till operations bait points per hectare may be required...

Maintaining and increasing the level of organic carbon in the soil will have benefits in terms of maximising water-holding capacity and crop productivity but farmers should not expect large returns from carbon credits... increase soil organic carbon (soc) by retaining crop residues, green manuring or cover cropping and reducing stocking rates on cropping paddocks... If carbon offsets were valued at $20/tonne of carbon, then the payments would be $2-3/ha and likely to be less than the cost of monitoring and administering a carbon credit program...

disease control using fungicides is an economic decision... fungicide timing Factors that influence spray timing recommendations include: growth stage; level of disease; length of the grain fill period; crop yield expectations; whether the region/season is high or low rainfall and if an early seasonal cut-off is expected; the resistance rating of the variety; and the likelihood of disease... Factors to consider in making this decision are: the presence of disease; yield potential; potential loss of yield and quality; commodity prices; and cost of fungicide plus application...

void surprises when selling stored grain by monitoring for insect pests monthly... insect control protects grain if stored grain is not properly managed there is a potential for it to become infested with stored grain pests... Protecting any grain stored from insect attack makes economic sense, because even feed grain can lose value though loss of protein or palatability, affecting livestock growth rates...

When first shifting to variable rate inputs, start with those that are not time-critical such as applying lime, gypsum or top-dressed nitrogen or potassium... In-paddock variation can be measured and mapped at harvest and during the growing season while crops are growing... But more detailed and accurate zones are produced using statistical software packages that combine different layers of spatial data (such as yield and EMI maps, see Figure 2)...

disease control using fungicides is an economic decision... Spray if disease threatens key plant parts (flag to flag-2) of varieties that are moderately susceptible (MS) or susceptible (S)... fungicide timing Factors that influence spray timing recommendations include: growth stage; level of disease; length of the grain fill period; crop yield expectations; whether the region/season is high or low rainfall and if an early seasonal cut-off is expected; the resistance rating of the variety; and the likelihood of disease...

TAKING CONTROL OF YOUR PERSONAL HEALTH.. Looking after your health is important for you, your family and your business... There are lots of ways to incorporate activity into your daily routine: walk or ride a bicycle to check crops or stock; do some stretches before you start work and throughout the day; wash the car or machinery by hand; do some gardening, mow the lawns with a push mower, dig a vegie patch; or participate in a structured recreational activity like golf, tennis, water-skiing and so on...

The checklist will help you get an appreciation of your current level of understanding of farm business management and identify areas you may want to focus on... There are references to recent GRDC Farm Business Management Fact Sheets to provide you with suggestions and guidance on improving your farm business management skills... 1. Strategy - setting direction and overseeing your business...

KEy pointS After decades of consistent phosphorus (P) application, many soils in the southern region now have adequate P reserves... As a result of this, along with high rates of P fertiliser being regularly applied, many soils in the southern grains region now have good soil P reserves... In a situation where 12 kilograms per hectare of applied P on 15 to 18cm row spacing has been recommended, the same result may be achieved with 9kg/ha of applied P if the crop were seeded on 25 to 30cm row spacing...

NORTHERN, SOUTHERN AND WESTERN REGIONS BETTER FERTILISER DECISIONS FOR CROP NUTRITION Inefficient or incorrect use of fertiliser can be a substantial, but somewhat hidden, cost in the cropping operation... KEY POINTS Fertilisers are a major cost of growing a crop... An initial soil test that includes both N and organic matter can provide a better understanding of potential N needs throughout the season...
