An alternative method for measuring plant available water in inorganic amendments
Inorganic amendments (IA) added to the rootzone of turfgrass are used to increase plant available water (PAW), however conflicting amounts of PAW contents have been reported for some of these amendments. The concept of PAW and the common technique used to estimate PAW in IAs have been reviewed. We hypothesized that hydraulic nonequilibrium in pressure-plate measurements results in an ...

Estimating plant-available water using the simple inverse yield model for claypan landscapes
Plant-available water (PAW) is one of the fundamental soil factors affecting crop yield, yet quantitative determination of plant-available water capacity (PAWc) at a field scale has been challenging. A simple inverse yield model (SIYM) has been devised and shown to be successful in estimating PAWc at a field scale for well-drained soils by matching simulated corn (Zea mays L.) yield with measured ...

Testing confirms more efficient fertiliser use lifts gross margins
This article discusses how accounting for the variation in crop yield potential due to season and soil type when formulating fertiliser rates can increase profit and reduce nutrient excesses. It shows that improved estimates of yield potential can increase gross margins by A$2–$20/ha over ‘farming-for-the-average’, with higher increases on soils with lower plant-available water capacity at drier ...

Axle-load impacts on hydraulic properties and corn yield in no-till clay and silt loam
Wheel traffic-induced compaction in no-till (NT) farming can alter soil hydraulic properties and reduce crop yields, but specific information on the impacts of different levels of axle loads on the relationships between soil hydraulic properties and crop yields under long-term NT systems is limited. Thus, this study set out to measure the differences in soil hydraulic properties including ...

Estimating genetic coefficients for the CSM-CERES-Maize model in North Carolina environments
CSM-CERES-Maize has been extensively used worldwide to simulate corn growth and grain production, but has not been evaluated for use in North Carolina. The objectives of this study were to calibrate CSM-CERES-Maize soil parameters and genetic coefficients using official variety trial data, evaluate model performance in North Carolina, and determine the suitability of the fitting technique using ...

Irrigation frequency effects on growth and ethanol yield in sweet Sorghum
With the increasing costs of fossil fuels, new methods of generating renewable fuels need to be researched and developed. This study was undertaken to assess the effects of irrigation frequency on crop growth and ethanol yield of sweet sorghum [Sorghum bicolor (L.) Moench]. Nine combinations of pre- and postanthesis irrigation frequencies triggered by 35, 50, or 65% depletion of plant-available ...

Late Spring Almond Irrigation
Late spring (late April to early June) is an important time in almond orchard development. During this time, the almond embryo is developing into a mature kernel. At this point in the season, proper irrigation management can be a major contributor to the difference between a marginal and major improvement in crop yield and quality. Development is complete when the kernel fills the shell ...

Tie-ridge tillage for high altitude pulse production in northern ethiopia
Pulses including faba bean (Vicia faba L.), lentil (Lens culinaris Medic.), and field pea (Pisum sativum L.) are important components of the cropping systems of semiarid high-altitude northern Ethiopia. Yield potential is often constrained by severe water deficits during grain fill which might be alleviated by reducing runoff throughout the season using microbasin or tie-ridge tillage. Research ...

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 led ...
