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 ...

Different Asias, same problems: negotiating the state-user interface in surface irrigation in China and India

This paper explores the dynamic interface of state-water users' relationships in large-scale surface irrigation in India and China, to inquire to what extent the issues encountered in large-scale irrigation management and governance are independent of regime characteristics. Though operating in very different overall political regimes, China and India exhibit strong similarities in the way a ...

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 ...

Brazil: Controlled Composting In Developing Countries

For more than six years, pilot and large-scale composting experiments have been done at the University of Vicosa in Vicosa, Brazil. We focused on low cost technologies, forced aeration techniques, vector and leachate control, process monitoring, staff training, and technical assistance to farms and city councils. It seems that an unwritten law for solid waste management for developing countries ...

Using Compost To Control Plant Diseases

Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...

Control of algal production in a high rate algal pond: investigation through batch and continuous experiments

For decades, arid and semi-arid regions in Africa have faced issues related to water availability for drinking, irrigation and livestock purposes. To tackle these issues, a laboratory scale greywater treatment system based on high rate algal pond (HRAP) technology was investigated in order to guide the operation of the pilot plant implemented in the 2iE campus in Ouagadougou (Burkina Faso). ...

Supply- and demand-side management of water in Gujarat, India: what can we learn?

Agriculture in Gujarat has grown rapidly over the last decade, driven at least partly by diversification to high value crops and dairying. High value agriculture requires better water control and offers higher returns for irrigation. Farmers, farm communities and the state government in Gujarat have responded to this requirement by implementing large-scale water supply and demand management ...

Crops flourish with Scalewatcher

Water is an essential component of horticulture and agriculture whether it is used for irrigating field-scale vegetables, nursery stock, flowers or fruit. Where water contains high degrees of calcium, magnesium and sodium, it can cause nutrient deficiency in plants and crops resulting in stunted growth and poor yields. Calcium also blocks irrigation systems and boilers in heated ...

Separation of solids and disinfection for agronomical use of the effluent from a UASB reactor

The present work addresses the preparation of the effluent from a full-scale upflow anaerobic sludge blanket (UASB) reactor for drip irrigation of orange crops. The pilot plant included a lamella plate clarifier followed by a geo-textile blanket filter and a UV disinfection reactor. The clarifier operated with a surface load of 115 m3m−2d−1, whereas the filter ...

Could food shortages bring down civilization?

One of the toughest things for people to do is to anticipate sudden change. Typically we project the future by extrapolating from trends in the past. Much of the time this approach works well. But sometimes it fails spectacularly, and people are simply blindsided by events such as today’s economic crisis. For most of us, the idea that civilization itself could disintegrate probably seems ...
