The optimization of the paddy field irrigation scheduling using mathematical programming
In planting rice, a significant amount of irrigation water is required to prepare the farmlands and do transplanting and this is directly related to the number of machines and workers available; that is, the more the length of plowing and transplanting process due to the lack of required machinery and labor, the more the water volume consumed. Therefore, in such conditions, it is important to ...

Conjunctive use of coffee effluent and pond water on the performance of robusta coffee and soil properties
A field experiment was conducted to study the influence of coffee effluent irrigation on performance of established robusta coffee, nutrient contribution and microbial activities in the soil. The results revealed that the field irrigated with coffee effluent from aerobic tank having COD of 1009 ppm, did not affect the yield of clean coffee (1309 kg ha-1) and it was on par with the plots irrigated ...

A strategy for sustainable livestock husbandry wastewater treatment in China
A strategy for sustainable treatment of the livestock husbandry wastewater is proposed, which is to recycle anaerobic treatment effluent as irrigation water. The existing treatment system was modified by deleting the treatment units after the anaerobic digestion. Chinese cabbage and Korean radish were selected as seeding plants in two sets of field irrigation experiments with various portions of ...

Quantification of soil surface evaporation under micro-scale advection in drip-irrigated fields
The objective of this study is to quantify soil surface evaporation under micro-scale advection in drip-irrigated fields. A numerical model for estimating soil surface evaporation under micro-scale advection, assuming drip-irrigated fields, is introduced. Results indicate that the soil surface evaporation changes spatially. Soil surface evaporation at the upwind edge of wet soil portions adjacent ...

Eima 2016: A success for irrigation
Energy saving and maximum efficiency are the cardinal points of agriculture 2.0. Today, through the micro irrigation and subsurface irrigation, agricultural production reached a high level of efficiency that assures quality and quantity. “Micro-irrigation”, or drip irrigation, is a method which allows the farmer to give the same amount of water to the roots of each plant, without ...

Acrylamide monomer leaching from Polyacrylamide-treated irrigation furrows
Water-soluble anionic polyacrylamide (WSPAM), which is used to reduce erosion in furrow irrigated fields and other agriculture applications, contains less than 0.05% acrylamide monomer (AMD). Acrylamide monomer, a potent neurotoxicant and suspected carcinogen, is readily dissolved and transported in flowing water. The study quantified AMD leaching losses from a WSPAM-treated corn (Zea mays L.) ...

Growing Produce Focuses on Drip Irrigation
Reporter Matthew Grassi from Growing Produce has just published an article about the choice growers face when switching from overhead to drip irrigation. They can save water and labor while deploying more sustainable and automated practices, but some may still be waiting to move forward. The article is titled, “Will Drip Replace Overhead Irrigation in Farm Fields?,” and you can read ...

Modeling irrigation management strategies to maximize cotton lint yield and water use efficiency
Increasing pumping costs and declining well capacities in the Southern High Plains compel producers to seek irrigation strategies to maximize yield and water use efficiency (WUE), which is the ratio of yield to evapotranspiration (ET). Cotton (Gossypium hirsutum L.) is suited to deficit irrigation using wells ranging from 0.29 to 0.93 L s–1 ha–1 capacity to supply limited, 2.5 mm d–1, to ...

Performance of solid-state sensors for continuous, real-time measurement of soil CO2 concentrations
Recent advances in sensor technology provide a robust capability for continuous measurement of soil gases. The performance of solid-state CO2 sensors (Model GMM220 series, Vaisala, Inc., Helsinki, Finland) was evaluated in laboratory, greenhouse, and irrigated winter wheat (Triticum aestivum L.). In ambient CO2 concentration, the GMM222 sensor averaged 427 ± 8.3 µL L–1. Under variable CO2 ...

Egypt, Kazakhstan and Australia. Plastic-Puglia is exporting its technology
Plastic-Puglia continues to invest in research and development of new products for irrigation. The company is moving into areas where the technology and water resources are scarce or mismanaged. In this field, the business group is well known and appreciated in over 40 countries worldwide. In recent weeks, the meetings in the palace of the Iranian Ministry of Agriculture to establish an ...

Treating Winery Wastewater Without Ponds
Wineries traditionally treat their wine process wastewater with aerobic (aerated) ponds to biologically degrade the biochemical oxygen demand (BOD). The treated wastewater from these ponds needs to have a BOD of 40 ppm or less (depending on the location of the winery) before the winery can discharge the water to the vineyards for irrigation. The discharge level of 40 ppm as well as the ...

Florida - Island Development case study
Steeped in history and tales of pirates, Blacks Island has become a residential paradise, thanks in part to creative decentralized wastewater solutions. In October of 2006, Blacks Island LLC received approval to begin construction of a twenty-six lot residential development on this seven-acre island located off the Florida panhandle in St. Joe Bay. The town of Port St. Joe sprang up in the ...

Does skip-row planting configuration improve cotton net return?
Cotton (Gossypium hirsutum L.) growers want information about alternative planting configurations to reduce seed, technology, and other production costs. We evaluated the impact of solid and 2 x 1 skip-row configurations on net returns for cotton grown in 25-, 76-, and 102-cm rows based on yield and fiber quality data from an experiment in adjacent nonirrigated and irrigated fields at Milan, TN. ...

AquaCrop model simulation under different irrigation water and nitrogen strategies
On a global scale, irrigated agriculture consumes about 72% of available freshwater resources. Deficit irrigation can be applied in the field to save irrigation water and still lead to acceptable crop production. The AquaCrop model is a simulation model for management of irrigation and nitrogen fertilizer. This model is a new model that is accurate, robust and requires fewer data inputs ...

Solid and skip-row spacings for irrigated and nonirrigated upland cotton
Producers of upland cotton (Gossypium hirsutum L.) are interested in alternative row spacings and planting patterns to improve productivity. We conducted factorial experiments for 3 yr in adjacent irrigated and nonirrigated fields at Milan, TN, of cotton grown in 25-, 76- and 102-cm rows, each planted in a solid and 2 x 1 skip-row pattern. Narrower rows and solid plantings tended to close canopy ...

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. ...
