Adapting to water scarcity: constraints and opportunities for improving irrigation management in Khorezm, Uzbekistan
Like many irrigation schemes in Central Asia, the one in Khorezm faces a two-fold challenge: on the one side, the severe problems inherited from the past need to be remedied and on the other side, the rising supply–demand gap driven by sharpening competition for water and climate change must be dealt with. Located in the lower part of the Amu Darya basin, Khorezm irrigation and drainage ...

Estimating the contribution of groundwater to rootzone soil moisture
In the Huaibei Plain basin, China, soybean is a main crop. During the soybean growth period, rainfall can vary largely and depth to watertable can also vary largely. The amount of water supplied to the soybean rootzone by groundwater affects soybean growth and yield. Accurate simulation of groundwater contributions to soybean rootzone soil moisture (groundwater contribution) can be important ...

How cooling irrigation systems benefit orchards
Typical Challenges in Orchards Managing an orchard comes with several challenges. Pest and disease control is a constant battle to protect trees and ensure high-quality fruit. Weather fluctuations, including extreme temperatures and storms, can harm tree health and productivity. Adequate water management, by balancing irrigation and drainage, is crucial for optimal growth. Nutrient management ...

Measurement and modelling of the water requirement of some greenhouse crops with artificial neural networks and genetic algorithm
Crop evapotranspiration is the most important parameter for management of irrigation systems in greenhouses. This study was conducted to determine the evapotranspiration of cucumber, tomato and peppers, using micro–lysimeter during seven months in a greenhouse located in central region of Iran. Reference evapotranspiration estimated using drainage lysimeters and the water balance of soil ...

Soil Moisture Terminology
Soil Moisture Terms. What do they mean and how do we use them? By the end of this short article you will hopefully understand the following statement. “For good crop growth, maintaining water above stress point will maximise vegetative growth. Setting a refill point above stress point will ensure there is always readily available water for the crop. Replacing ...

Irrigation - Water Management, Pollution and Alternative Strategies
Irrigated agriculture is the most significant user of fresh water in the world and, due to the large area occupied, is one of the major pollution sources for the water resources. This book comprises 12 chapters that cover different issues and problematics of irrigated agriculture: from water use in different irrigated systems to pollution generated by irrigated agriculture. Moreover, the book ...

Evaluation of the management practice for controlling herbicide runoff from paddy fields using intermittent and spillover-irrigation schemes
Two water management practices, an intermittent irrigation scheme using automatic irrigation system(AI) and a spillover-irrigation scheme (SI), were compared for the fate and transport of commonly used herbicides, mefenacet (MF) and bensulfuron-methyl (BSM) in experimental paddy plots. Maximum mefenacet concentrations in paddy water were 660 and 540 µgL−1 for AI and SI plot, respectively. ...

Potential impacts of on-site greywater reuse in landscape irrigation
This study investigated the effects of irrigation with different types of waters on soil, plants, and public health. The test plant was ryegrass grown in 12 planters filled with sandy loam soil and irrigated with three types of waters (4 planters for each type): freshwater, raw domestic light greywater (GW), and treated domestic light GW. The sodium adsorption ratio (SAR), EC, pH and alkalinity ...

Unlocking Precision and Sustainability with Portable Soil EC Detectors
For millennia, farmers have tilled the land, guided by intuition and tradition. But beneath the surface, in the hidden realm of the soil, lies a powerful language waiting to be deciphered. A language not of words, but of electrical whispers, dictating the very foundation of plant growth and ecosystem health. This language is spoken in terms of Electrical Conductivity (EC), and to understand it, ...

Why Drip Irrigation Design is Crucial to Your Success
Drip irrigation is one of the most cost-effective and efficient watering methods in agriculture. It has become incredibly popular in the past 50-years and has been widely adopted by agriculturalists in dozens of countries throughout the world. In simple term, drip irrigation works by sending water through plastic pipes into drip emitters. These emitters are specifically designed to release water ...
