Subsequently a key extension publication was developed that outlines the considerations required prior to the use of animal manures and organic wastes in grain cropping systems... The research highlights that a large volume of available data exists on the use of manures and organic amendments in cropping systems... Higher rainfall cropping zones (more than 600 mm/year) have the greatest capacity to store soil carbon (18 tonnes per hectare compared with 2.5 tonnes per hectare for rainfall less than 600 mm/yr) and are more likely to positively respond to organic inputs...

Shaun Nolan says diminishing market returns were the catalyst for major changes to their farm management, aimed mostly at efficiency improvements... "Without the moves to finetune efficiency in grain, forage and beef cattle production in the past decade, I doubt our family would still be farming today," Shaun says bluntly... Leaving behind work as an agronomist with Queensland Cotton, Shaun has spearheaded the changes since returning in 2003 to the property he farms with his wife, Amanda, and parents, John and Elizabeth...

Growers set to profit from nutrition knowledge.. Northern region growers are being offered a valuable insight into the critical relationship between soil nutrient balance and crop profitability during a series of More Profit from Crop Nutrition (MPCN II) workshops and field walks... Department of Agriculture, Fisheries and Forestry (DAFF) researcher and project leader, Dr Kaara Klepper said the workshops provided growers with an opportunity to enhance their knowledge of soil and crop nutrition, and discuss individual issues related to crop production, soil testing, nutrient budgeting, crop yield and grain protein targets...

Feedlot manure can provide half price nutrients.. With around 450,000 cattle on feed in Queensland, there is close to 500,000 tonnes of manure to be utilised as fertiliser each year... Potassium: K There is more than enough K when manure is used to supply P. Sorghum yielding 5 t/ha, has K removal around 22 kg/ha/yr, which means 170 kg of K in 10 t/ha of manure would last 7 years...

The objective of the report is to analyse the energy system within a fee options are available for utilising an energy output (manure), the value of that and what implications emissions and their trade may have on its use... vii Existing bioenergy developments have proved difficult to justify in feedlots in th a result there has been little interest in this area, anaerobic digesters are not manure feedstock and conventional gasifiers struggle to cope with high ash content manure... Other uses proposed include fly ash in construction mate concrete and road base...

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...

Every nine weeks Grant supplies 90 tonnes of cereal straw and removes 50 truckloads of chicken shed waste - a total of 5500t of manure each year... By providing all the straw, Grant has created a 'closed loop' to prevent outside weed seed contamination in the manure. ".. Grant has bought a telehandler (a telescopic handler) and a 25-cubic-metre spreader and an additional truck is contracted to cart some of the manure...

The paddock is finished with a conventional method of ploughing before a crop is planted... Richard Wright (2012), principal of Wright Produce Ltd, U.K, stated "we started in pigs in the 1960's and now run 3,600 sows; the pigs make us money but it's the value of the manure that keeps us in pigs... Given that there is a good chance of extensive soil disturbance by the pigs at the same time, nutrient runoff could happen in heavy rain, polluting water ways and causing water quality problems...

Intensive livestock industries are rapidly expanding in southern Qld and northern NSW and the by-products can be an attractive source of nutrients for use in broadacre farming systems... While manures and other organic waste materials (eg. sugarcane mill muds, by-products from ethanol plants, municipal biosolids) can provide many benefits to soil health, fertility and crop productivity, there are also a number of issues that growers and advisors need to consider before determining the most effective combination of management strategies to use, and the economic benefits (if any) of making a change to current practices... The paper highlights some of these issues, while providing examples of recent research to look at the roles of feedlot manures in supplying N and P to crops...
