Resource management for growers
Natural resources such as soil, water and nutrients should be managed to ensure they are available now and in the future.
Efficient use of resources reduces costs to farmers, and reduces the impact of agricultural practices on the environment.
Understanding soil management in farming soils
In general, soils in the Northern Territory (NT) are very poor.
Soil structure is poor and they lack sufficient naturally available plant nutrients to produce a good crop of vegetables. This results in low moisture and nutrient holding capacity.
To find out more about managing and improving soil for agricultural use, read the following publications:
- effects of agricultural management on soil carbon and pH in the Douglas Daly region of the NT
- green manure cropping in horticulture
- improving soil structure and pH levels in top end soils for horticulture
- supporting sustainable development - risks and impacts of plant industries on soil condition .
Understanding water and irrigation in farming soils
Horticulture in the NT relies heavily on irrigation for its sustainable development and viability.
Irrigation is one of a number of factors which need to be carefully managed for efficiency, cost, yield and production.
To find out more about managing water and irrigation in agricultural production, read the following publications:
- review of mango irrigation research in NT - (2010) (combined research from the NT Government and the CSIRO on water use in mangoes)
- NT mango irrigation survey 2012: how much fruit from how much water?
- irrigation of horticultural crops
- the environmental impact of plant industries on inland water in the NT
- rainfall at Katherine
- the method for estimating crop irrigation volumes for the Tindall limestone aquifer, Katherine, water allocation plan
- approximate water use for Darwin area horticulture .
Understanding nutrient efficiencies in farming soils
Farmers, growers and others involved in Australia's agriculture industries can significantly improve their nutrient use efficiency.
The Australian Government has programs to encourage farmers and land managers to create credits for carbon biosequestration and pollution reduction activities associated with agricultural production.
To find out more about the carbon farming initiative, go to the Australian Government's Department of Agriculture, Water and the Environment website.
To read more about the emissions reduction fund, go to the Australian Government's Department of Industry, Science, Energy and Resources website.
For more information for growers, go to the N2O Network website.
To understand and improve nutrient efficiencies in agriculture, read the following publications:
- greenhouse gas emissions in top end horticulture
- reducing nitrous oxide emissions when fertilising hay crops with nitrogen fertiliser
- vegetable fertilizer guide for top end gardeners
- optimising nutrient management for improved productivity and fruit quality in mangoes - go to the Department of Industry, Tourism and Trade website.
You should also watch the video about measuring N2O emissions on the Department of Industry, Tourism and Trade's YouTube.
