Manage your Pivot Remotely with FieldNET
Zimmatic Controllers – The Only Control Panel Compatible with Fieldnet Control panels have always been used on pivot sprinklers. New smart control panels, however, are revolutionizing pivot irrigation. These devices reduce water consumption and lead to savings in time and labour. Zimmatic control panels have everything for the grower who is ready to take complete control of their ...

Giving way to the elephant: the dynamics of participation in the management of a Balinese subak
Irrigation Communities, a common reference point for Water Users' Associations, are corporate groups that manage irrigation systems under local or indigenous charters. This paper begins by pointing out that local control in irrigation does not necessarily imply effective participatory management. It then undertakes a detailed examination of the internal dynamics of participation in an Irrigation ...

Study on the joint probability distribution of irrigation water volume and irrigation water efficiency
Using the copula method, the joint probability distribution of irrigation water volume and efficiency is constructed, and their joint return period is also described to reveal the encounter probability of irrigation water volume and efficiency. Furthermore, the conditional probability of irrigation water efficiency with different water volumes is built to show the quantitative effects of flow ...

A tale of two developments of irrigation: India and USA
This paper offers a comparative study of economic history of two of the four largest irrigation systems in the world covering a period of about one hundred years, and points out the major lessons learnt from development experiences. This is especially significant since one is a developing country (which was considered a "more developed" irrigation system a century ago) and the other is a ...

Irrigation Service Contract Template
If you're not using legally-binding contracts in your irrigation business it's probably a good idea you start to. They're one of the irrigation business essentials. Not only can contracts provide legal backing in case of potential discrepancies down the road but they can also provide a foundation of information for your day-to-day operations. ...

An analysis of groundwater irrigation expansion in India
This paper suggest that groundwater irrigation expansion in India is driven mainly by the population pressure and not necessarily dependent on the change in surface water irrigation. However, in the districts irrigated by Groundwater only, our findings indicate that the marginal effect of groundwater on Gross Irrigated Area (GIA) is lower than that in the district endowed with both surface and ...

Impact analysis of reducing multi-provincial irrigation subsidies in China: a policy simulation based on a CGE model
Water pricing policy is believed to be an efficient method for addressing the water scarcity problem in China. The motivation of this study is to provide a better understanding of how reducing irrigation subsidies impacts farming sectors and rural households. We apply a Computable General Equilibrium model to simulate the irrigation water and irrigation subsidy in 16 provinces. The results ...

The effect of winter flood irrigation with saline water on groundwater in a typical irrigation area
Flood irrigation in the winter has been widely applied in northwest China for several years, but little attention has been paid to the flood irrigation program to date. In order to seek a reasonable irrigation quota, a flood irrigation experiment using two common quotas (1,800 and 1,200 m3 ha−1) was conducted in an area irrigated by saline water in the Nanjiang basin with shallow ...

How does participatory irrigation management work? A study of selected water users' associations in Anand district of Gujarat, western India
Measuring the performance of water users' associations (WUAs) is a complex task. Literature associates a large number of parameters with their success and failure. This paper presents an in-depth study of two WUAs that are considered to be functioning well by the irrigation department in Anand, India. It discusses some new issues and innovations being tried out in Anand, namely: (1) ...

The implementation of participatory irrigation management in Andhra Pradesh, India
This paper discusses the implementation of irrigation reform policy in the State of Andhra Pradesh, India. It reports on the impact of the introduction of participatory irrigation management (PIM) in two secondary canals (distributaries) in the Tungabhadra Right Bank Low Level Canal irrigation system. The empirical findings are that the rural elite has captured most of the seats in the water ...

Creeping bentgrass putting green turf responses to two summer irrigation practices: Rooting and soil temperature
Light and frequent (LF) and deep and infrequent (DI) irrigation are two common practices for golf course managers. Few studies have compared the effects of these two opposing irrigation practices on summer root performance in creeping bentgrass (Agrostis stolonifera L.). The objectives of this field study were to quantify summer root development and longevity in response to LF vs. DI irrigation ...

Olives - Monastir, Tunisia- Case Study
Ecotube was installed in two lines, left and right of each tree. The results of the yield were much better then what was achieved prior to ecotube with drip irrigation. The trees have developed stronger roots and used less water since the installation. Even in the hot summer month, the irrigation quantity is ...

Factors affecting phosphorus exports from sites irrigated with abattoir wastewater
Abattoir wastewaters often contain significant quantities of phosphorus, inorganic salts, nitrogen and biodegradable organic materials. The nutrients in abattoir wastewaters are potentially useful for plant production and in many countries the application of abattoir wastewaters to land is considered a preferable option to other forms of treatment. In this paper we investigate the factors that ...

Eggplant- Saudi Arabia - Case Study
Eggplants in Saudi Arabia are usually planted in sandy soils inside a greenhouse with temperatures rising upt to 50°C. With the utilization of ecotube, the harvest could be done two weeks earlier and the biomass was 48% higher in comparison to conventional drip irrigation systems. All while saving aproximately 90% water. Most of it due to no evaporization. In the picture, the plants on the ...

Extracting physical homogeneous regions out of irrigation networks using fuzzy clustering method: a case study for the Ghazvin canal irrigation network
Improving the current operation and maintenance activities is one of the main steps in achieving higher performance of irrigation networks. Improving the irrigation network management, influenced by different spatial and temporal parameters, is confronted with special difficulties. One of the controversial issues often faced by decision-makers is how to cope with the spatial diversity of ...

Can drip irrigation technology be socially beneficial? Evidence from Southern India
Drip irrigation has received considerable attention from policy makers because of its significant contribution towards resource saving, enhanced agricultural productivity and environmental sustainability. This paper explores the potential benefits of drip irrigation adoption by addressing the social benefits and costs in Southern India. The study shows that adoption of drip irrigation technology ...

Irrigation demand modelling using the UKCP09 weather generator: lessons learned
The determination of irrigation demand is typically based on crop modelling using a long historic record of local daily weather data. However, there are rarely adequate weather station records near to given sites; often any local records cover a limited number of years, are incomplete, costly or are of poor quality. This paper examines whether version 1 of the UKCP09 weather generator can ...
