Crop water use efficiency
Crop water use efficiency (WUE), or yield per unit of water used, can be improved through irrigation management and methods, including deficit irrigation (irrigating less than is required for maximum yields) and supplemental irrigation (irrigating to supplement precipitation so as to avoid crop failure or severe yield decline). Thus, WUE is key for agricultural production with limited water ...

How much water is needed to grow bioenergy crops?
A Dutch study has assessed the water requirements of 13 bioenergy crops across the world. The findings could help select the best crops and locations to produce bioenergy. The EU climate action and renewable energy package has set a target of increasing the share of renewable energy to 20 per cent of energy used by 20201. This includes a minimum 10 per cent share for transport, which could ...

Flow4 sap flow logger from Dynamax press release
Flow4 Sap Flow Logger - Irrigation Control from Dynamax Inc (281-564-5100), is a stand-alone water balance measurement system for irrigation automation based on plant transpiration. Four Dynagage sap flow sensors read crop water consumption. These measurements are compared to rainfall, soil moisture and irrigation water supplied. The water balance or water deficit then determines the amount of ...

Soil Moisture Probes as a management tool for broadacre cropping enterprises
Are you interested in being involved in a 'Cutting Edge' Agronomic Project and Discussion Group? SANTFA and Rural Directions Pty Ltd, are kicking off a project focussing on Soil Moisture Probes as a management tool for broadacre cropping enterprises, which will run from July 2009 through to May 2010. The project is about using soil moisture monitoring as a guide for making informed decisions in ...

Where is your soil water? Crop yield has the answer
Crop yield is highly dependent on soil plant-available water, the portion of soil water that can be taken up by plant roots. Quantitative determination of the maximum amount of plant-available water in soil using traditional methods on soil samples remains challenging, especially at the scale of an entire field. However, a map of plant-available water capacity for a field would be instrumental in ...

Pivot App update: Water allocation, NDVI and much more
Our Pivot App has been recently upgraded, giving row crops growers even better visibility of their plants, soil and irrigation status to support their decision making. Let's see what's new. NDVI inside NDVI maps have been added without additional cost to all our customers. With Sentinel-2 NDVI images for each plot, every 5 days (depending on cloud cover) growers have another significant data ...

Fertiliser can offset heat for African farmers
[NAIROBI] African smallholders in dry areas can overcome climate change and even double crop yields if they invest in fertiliser use and harvest rainwater, researchers have found. Farmers in arid and semi-arid areas usually protect themselves from climate-related losses by investing as little as possible in farm inputs such as fertilisers. But in doing so they fail to grab opportunities for ...

Mixed crop-livestock farming could help adaptation in Africa
According to new research, African farms with both crops and livestock could be more resilient to climate change than farms that only grow crops. The research suggests that policy makers should support farmers in making the switch to integrated farming. The Intergovernmental Panel on Climate Change (IPCC) has indicated that agriculture in tropical under-developed countries is the most vulnerable ...

Better water management could improve global crop production
A new global study is the first to quantify the potential of water management strategies to increase crop production. It indicates that a combination of harvesting run-off water and reducing evaporation from soil could increase global crop production by 20 per cent. The EU has recognised the impact of climate change on water and the subsequent effects on agriculture in its white paper on ...

Straw covering on soil can increase crop yields and improve the efficiency of water use
Straw from previous harvests can be used to help increase crop yields and improve the efficiency of water use in arid regions, finds a new study from China. By testing different techniques to improve water efficiency, the researchers found that the most effective method involved using straw to cover the soil when growing maize and wheat together in the same growing season. In north-western ...

Farmers and Nonprofits Sue Trump`s USDA Over Organic Soil-Less Loophole
Today, Center for Food Safety (CFS), along with a coalition of organic farms and stakeholders, filed a lawsuit challenging the United States Department of Agriculture's (USDA's) decision to allow hydroponic operations to be certified organic. The lawsuit claims that hydroponic operations violate organic standards for failing to build heathy soils, and asks the Court to stop USDA from allowing ...

Squeezing more crop out of each drop of water
Studies in China and Colorado by Agricultural Research Service (ARS) scientists and cooperators have revealed some interesting tactics on how to irrigate with limited water, based on a crop’s critical growth stages. Laj Ahuja, research leader at the ARS Agricultural Systems Research Unit in Fort Collins, Colo., and colleagues conducted the studies. As one example, with wheat in China, they ...
