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 ...

Select groundcover management systems found viable for organically managed apple orchard
Determining and implementing orchard management practices that can improve soil organic matter is one of the primary goals of the USDA's National Organic Program. For producers in the southeastern United States, where interest in small-scale and organically managed orchards is growing, the challenge can be finding combinations of groundcover management systems and organic nutrient sources that ...

Soil moisture for crop health topic of symposium
Soil moisture sensing through either contact or remote technology captures soil-plant-water information that relates closely with plant water availability and use. Innovations in remote sensing technologies can inform plant health assessments and more. The “Soil Moisture Sensing for Crop Health Assessment and Management” symposium planned at the Resilience Emerging from Scarcity ...

Soil moisture monitoring for better irrigation and crop nutrition in Cucumbers
Soil moisture monitoring is often thought of as a water saving technology. While this is true, there are other significant benefits from soil moisture monitoring. Crop nutrition is intrinsically linked to crop irrigation. Many nutrients move quickly with water or only move through plants when water is available. Nitrogen (N) is released in water and too much irrigation can result in nitrogen ...

Perfect Poinsettias for Christmas? Controlling Compost Moisture Can Remove the Need for Chemical Growth Retardants
Poinsettias, the classic Christmas pot plant, are grown in their thousands in UK nurseries from late July onwards, but growers have to rely on the use of plant growth regulators (PRGs) to ensure that the optimum height and number of bracts is achieved by early December. With protective environmental legislation threatening to reduce the availability and use of such PGR treatments, a project ...

New irrigation strategies for pecans in humid climates
Georgia is the largest pecan producing state in the U.S. Although this humid region receives an average of 127 cm or more rainfall annually, periods of moisture stress can occur during the pecan growing season, particularly during August and September when pecans are in the kernel-filling stage and water demand is at its peak. Pecan producers throughout the region depend on irrigation strategies ...

Simulating the effect of climate change on agriculture
Increased atmospheric CO2 levels and climate change are believed to contribute to extreme weather conditions, which is a major concern for many. And beyond extreme events, global warming is also predicted to affect agriculture.1,2 While climate change is expected to affect agriculture and reduce crop yields, the complete effects of climate change on agriculture and the resultant human food ...

Simulating Agricultural Climate Change Scenarios using Controlled Growth Chambers
Extreme weather, believed to result from climate change and increased atmospheric CO2 levels, is a concern for many. And beyond extreme events, global warming is also expected to impact agriculture.1,2 Although it is expected that climate change will significantly affect agriculture and cause decreases in crop yields, the full effects of climate change on agriculture and human food supplies ...
