Deficit irrigation optimization of cotton with aquacrop
Given the current pressures to reduce irrigation water use, it is important to optimize the use of water in irrigated agriculture. This work was aimed at determining the optimum level of applied irrigation water (AIW) for cotton (Gossypium hirsutum L.) production in southern Spain under several climatic and agricultural policy scenarios. To generate the yield response to variations in AIW, we ...

Novel simulation-based algorithms for optimal open-loop and closed-loop scheduling of deficit irrigation systems
The scarcity of water compared with the abundance of land constitutes the main drawback within agricultural production. Besides the improvement of irrigation techniques a task of primary importance is solving the problem of intra-seasonal irrigation scheduling under limited seasonal water supply. An efficient scheduling algorithm has to take into account the crops' response to water stress at ...

Using Soil Water Sensors to Improve Irrigation Management
Abstract Irrigation water management has to do with the appropriate application of water to soils, in terms of amounts, rates, and timing to satisfy crop water demands while protecting the soil and water resources from degradation. In this regard, sensors can be used to monitor the soil water status; and some can be used to calculate irrigation amounts and to decide when to optimally irrigate. ...

From (cyber)space to ground: new technologies for smart farming
Increased water demand and climate change impacts have recently enhanced the need to improve water resources management, even in those areas which traditionally have an abundant supply of water, such as the Po Valley in northern Italy. The highest consumption of water is devoted to irrigation for agricultural production, and so it is in this area that efforts have to be focused to study ...

Irrigation water demand and implications for groundwater pricing in Pakistan
This study employs the positive mathematical programming (PMP) approach to estimate groundwater derived demand for irrigation using a cross-sectional dataset of 200 predominantly groundwater irrigated farms from the Punjab province of Pakistan. First, we find that the PMP optimal solution uses less water than what is available (being extracted) in order to make farmers allocate all the ...

Efficient Vineyard Irrigation Series #2: How to Predict Soil Moisture for the Next Two Weeks
As viticulturists and grape growers know, understanding current and future soil moisture content is a prerequisite for taking actions to reduce crop variability, optimise water usage, and tackle irrigation problems. Adequate soil moisture is critical for ensuring fruit quality. Water stress and over-vigorous growing conditions can result in inferior fruit quality and reduce profitability. ...

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 ...

Participative modelling to help collective decision-making in water allocation and nitrogen pollution: application to the case of the Aveyron-Lere Basin
The aim of this study is to develop simplified tools and methods in collaboration with local stakeholders to facilitate collective decision-making. The project is based on a series of experiments carried out between farmers and environmental officers and researchers (Aquae Project)1 on the Aveyron-Lere catchment area. Within this framework, a model of the catchment area was constructed to examine ...

Modeling the impacts of increase in temperature on irrigation water requirements in Palakkad district: a case study in humid tropical Kerala
Rise in temperature is one of the predicted impacts of climate change with significant implications on water resources management. An attempt has been made to calculate the water requirement of crops in different agro-ecological zones of Palakkad district in humid tropical Kerala using the CROPWAT 8.0 model. Sensitivity analysis was done for a simulated rise in temperature from 0.5 to 3.0 ...

Cotton subsurface drip and overhead irrigation efficiency, maturity, yield, and quality
Subsurface drip (SSD) is used as a water-efficient alternative to overhead irrigation in many crops. This study compared soil water, water use, crop maturity, lint yield, and fiber quality of cotton (Gossypium hirsutum L.) grown with SSD to cotton grown with overhead irrigation. Three experiments were conducted at two Georgia locations in 2004 and 2005. Treatments consisted of overhead irrigated, ...

Evaluation of yield, quality and crop water stress index of sugar beet under different irrigation regimes
This study was carried out to evaluate the use of the crop water stress index (CWSI) for irrigation scheduling of sugar beet for two years under the semi arid climate of Iran. Statistical relationships between CWSI and yield, quality parameters and irrigation water use efficiency (IWUE) were investigated. Irrigations were scheduled based on 100 (I100), 85 (I85), 70 (I50) and 0% (I0) of plant ...

Potential water savings associated with agricultural water efficiency improvements: a case study of California, USA
This study analyzes the potential for water savings from irrigation efficiency improvements in California, USA. We model water savings associated with three efficiency scenarios in wet, average and dry water years. The ‘efficient irrigation technology’ scenario shifts a fraction of the crops from flood irrigation to sprinkler and drip systems; the ‘improved irrigation scheduling’ scenario uses ...

Improved Agricultural Irrigation Scheduling Using a Soil Water Content Sensor - Case Study
Abstract The key to scheduling irrigation timing and amounts is determining moisture depletion in the soil. Two common methods include tracking crop evapotranspiration (ETc) and tracking the water content with a sensor buried in the soil. In Colorado, a popular online tool that estimates the ETc for a variety of well-irrigated crops is the Colorado Agricultural Meteorological Network (CoAgMet). ...
