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 Top End 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 publications listed below.
- 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 Northern Territory 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 publications listed below.
- 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

Understanding nutrient efficiencies in farming soils
Farmers, growers and others involved in Australia's agriculture industries can significantly improve their nutrient use efficiency.
To find out more, go to the Australian Department of Agriculture and Water Resources website about the Carbon Farming Initiative and the Australian Department of the Environment's website about the Emissions Reduction Fund.
Go to the N2O Network website which has information for growers
Read the publications listed below about understanding and improving nutrient efficiencies in agriculture.
- 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 Primary Industry and Resources website.
