Agricultural Water Management
Water Wisdom: A Comprehensive Guide to Agricultural Water Management Water is essential for life and crucial for agriculture. As the global population continues to rise, so does the demand for food production. However, with limited resources such as water, it has become increasingly important for agricultural industries to find sustainable ways to manage this precious resource. In today’s ...

Conjunctive effect of water productivity and cultivation pattern on agricultural water management
Agricultural water resources are scarce in Iran, and agricultural water management is essential to overcome this limitation. Determination of the water productivity index (WP) using the methods of optimization of cropping patterns and optimal water allocation is the most effective tool in water management in the agricultural sector. In this study, a non-linear optimization model was used to ...

Optimizing Agricultural Water Management through Water Quality Sensors
Water is a precious resource that plays a critical role in agricultural production. As the global population increases, meeting the demand for food and fiber becomes increasingly challenging, particularly in regions facing water scarcity. The utilization of water in agriculture must be efficient, sustainable, and environmentally friendly. This article explores how water quality sensors have ...

Review of agricultural water management policies in Near East and North African Region in light of water scarcity
This paper explores the current debate about water management policies and the factors affecting their formulation and implementation in the arid and semi–arid zones of the Near East and North African Region (NENAR). In this context, relevant and significant experiences of other countries in the world facing similar challenges are also considered (Sachdeva, 2009). The literature pertaining ...

Estimation of maize evapotranspiration using extreme learning machine and generalized regression neural network on the China Loess Plateau
Accurately estimating crop evapotranspiration (ET) is essential for agricultural water management in arid and semiarid croplands. This study developed extreme learning machine (ELM) and generalized regression neural network (GRNN) models for maize ET estimation on the China Loess Plateau. Maize ET, meteorological variables, leaf area index (LAI), and plant height (hc) were continuously ...

Incentives and instruments for sustainable irrigation
This book looks at Sustainable Irrigation in a holistic way, considering the multidisciplinary objectives of sustainable agriculture, sustainable water management, sustainable water infrastructure, sustainable irrigation communities and a sustainable environment, the need to reallocate water between competing users, and the need for water and food security in an environment of scarcity. It does ...

A time domain transmission sensor with TDR performance characteristics
Abstract Time domain reflectometry (TDR) has become a standard method for determining water content in soils and porous media. However, the cost of instrumentation and the level of user ability required often limit its application, especially for agricultural and urban soil water management. The objective of this paper is to report on a new, lower cost time domain transmission (TDT) sensor and to ...

Spectral Reflectance Properties of Winter Cover Crops in the Southeastern Coastal Plain
Conservation tillage is a commonly adopted best management practice for reducing runoff and erosion, and increasing infiltration. Yet current methodologies in place to monitor conservation tillage adoption are largely inappropriate for regional or national assessments. A major goal of this study was to evaluate the spectral response properties of four alternative winter cover crops using remotely ...

Analysing the links between agriculture and climate change: can 'best management practices' be responsive to climate extremes?
Rural communities the world over depend on agriculturally–based livelihoods. In the Canadian prairies, access to sufficient quality and quantity of water can be challenging. Agriculture is fundamentally susceptible to access to water during critical crop germination and growth periods. Climate change models for the Canadian prairies indicate, in general, that summer growing seasons will ...

Soil Water Sensors for Agriculture – Theory and Issues
Soil water sensors have been used for irrigation and water management in agriculture for many years, but with limited success in many cases. Nonetheless, the use of soil water sensors in increasing as water scarcity increases and, conversely, problems associated with over irrigation also increase. Common problems with soil water sensing included sensor failure, problems with wiring, lack of or ...

Land, water, and forests : assets for climate resilient development in Africa
Africa is a continent rich in natural resources. Its land, water, and forests underpin the sustained productivity of food crops and livestock on which millions of Africans depend directly for their livelihood and survival. These resources are major assets on which most countries depend for economic growth and sustainable development. In the face of growing climate change threats, such as ...

Nitrate leaching from a potato field using adaptive network-based fuzzy inference system
The conventional methods of application of nitrogen fertilizers might be responsible for the increased nitrate concentration in groundwater of areas dominated by irrigated agriculture. Appropriate water and nutrient management strategies are required to minimize groundwater pollution and to maximize nutrient use efficiency and production. Design and operation of a drip fertigation system ...

Five benefits of agricultural smart irrigation
Population growth and an increase in irrigated agricultural land lead to a greater need for water and energy, at a time when global warming and rising greenhouse gas emissions are posing a real environmental challenge. In this context, the benefits of smart irrigation, i.e., using the exact amount of water needed for each crop, help to optimize this scarce resource. If we take a closer look at ...

Remote monitoring helps growers, water districts do their jobs
Propeller flow meters have long been an important tool for agricultural irrigation management. As water scarcity and resource management have become increasingly critical, getting the most timely, accurate readings available from those meters is becoming more important than ever. Here is how growers and water conservation districts (WCDs) are each getting the best of both worlds for their own ...
