Ground cover cuts evaporation
Increasing profitability with ground cover
Story by BOB McGUFFICKE AND JEFF LOWIEN
Soil and water are the essence of agriculture for grazing and cropping but these aspects can be tremendously influenced by preserving good ground cover.
Ground cover is a quite excellent indicator of both the production and sustainability of pastures and crops and includes increasing and dead plants and litter.
Litter plays a essential part in minimizing rainfall runoff, evaporation and minimising extremes of soil temperatures. Sufficient levels of litter can reduce evaporation by 50 per cent and minimize temperatures in the best five cm of soil by up to 20 degrees C compared to bare soil in hot summer time situations.
It is also the major meals supply for micro-organisms, with high levels of microbial activity resulting in elevated organic matter, cycling of nutrients and improvements in soil structure and water infiltration.
Most soil organisms are in the top five cm of soil and their activity depends on suitable soil temperature and moisture, and sufficient litter.
Investigation on the North West slopes has shown that maintaining sufficient ground cover is quite important for improving the water cycle for sustainable grazing systems. The water cycle is a balance in between evapotranspiration (water use by plants and evaporation), runoff and deep drainage.
While you can not handle the rainfall you receive, several of your on-farm management decisions can influence the effectiveness of rainfall.
Evapotranspiration represents about 93 per cent of annual rainfall on the North West Slopes. In a 700 mm rainfall zone with low ground cover up to 520 mm can be lost as evaporation from the ground surface.
Investigation has shown that this evaporation can be halved if ground cover, which includes plant litter, is elevated from 40 per cent to 70 per cent.
Also by increasing ground cover, runoff is reduced (70mm/year) and by utilizing deep rooted perennials a additional 5mm/year is gained by much less deep drainage. Add these figures and it is attainable to obtain an further 300mm of effective rainfall for added growth resulting in enhanced profits for you from improved pasture or crop production.
With climate change occurring and the possibility of decrease rainfall, this additional successful rainfall would be worth its weight in gold.
Ground cover is the most effective way to maximise water infiltration by minimising rainfall runoff and soil erosion. Adequate ground cover is important to maintaining healthier soil and vegetation and productive pastures.
Research has shown that at least 70 per cent ground cover is necessary on the North West Slopes to minimise soil degradation and sustain production. This figure increases in steeper slopes and far more erodible soil sorts and in the Tablelands grazing circumstance should be at least 95 per cent.
