  • The sanitation and urban agriculture nexus: urine collection and application as fertilizer in São Paulo, Brazil

    Separately collected urine is an attractive potential fertilizer because of its high nutrient content, low cost, and inherent linkage of urban wastewater management and peri-urban agriculture. Urine from waterless urinals was applied to corn and lettuce plants to examine the impact of urine application rates and frequency on plant growth and soil parameters. In both corn and lettuce ...

  • Opportunities for saving and reallocating agricultural water to alleviate water scarcity

    As water scarcity worsens globally, there is growing interest in finding ways to reduce water consumption, and for reallocating water savings to other uses including environmental restoration. Because irrigated agriculture is responsible for more than 90% of all consumptive water use in water-scarce regions, much attention is being focused on opportunities to save water on irrigated farms. At ...

  • Effects of two different water sources used for irrigation on the soil geochemical properties and the quality of the Lohan guava (Psidium guajava L. Lohan)

    The effect of two different water sources (treated waste water and lake water) used for irrigation on the soil geochemical properties and the fruit quality parameters of the Lohan guava were studied. The fruits' physical attributes, physicochemical attributes, nutritional attributes, mineral content as well as consumers’ acceptance were evaluated. The properties of the different water sources ...

  • Impact of agricultural water reallocation on crop yield and revenue: a case study in China

    Our study area in the People's Victory Canal Irrigation District of Henan Province in China has been transferring agricultural water to the city for municipal use. This study starts with an examination of the impacts of irrigation frequency, irrigation water sources, and irrigation water supply performance on crop yield and net crop revenue, using data from a survey of 182 households in the ...

  • It’s time to stop overspending our freshwater budget

    If freshwater is to remain a renewable resource, we must balance supply and demand on farms, in cities, in industry and in power production. When you look to the year ahead, what do you see? Ensia recently invited eight global thought leaders to share their thoughts. In this interview with Ensia contributor Lisa Palmer, World Resources Institute Global Water Program director Betsy Otto responds ...

  • Assessment of swine-specific bacteriophages of Bacteroides fragilis in swine farms with different antibiotic practices

    We assessed the occurrence and specificity of bacteriophages of Bacteroides fragilis in swine farms for their potential application in microbial source tracking. A local B. fragilis host strain, SP25 (DSM29413), was isolated from a pooled swine feces sample taken from a non-antibiotic farm. This strain was highly specific to swine fecal materials because it did not detect ...

  • Sustainable Farm Practices for Rice Farming

    Rice is the third-largest crop production, after sugarcane and maize. The main producers of rice are the nations of China, India, Indonesia, Bangladesh, and Vietnam. Rice is a staple crop. More than half the people in the world, about 3.5 billion people, rely on its production. Not only is rice a key source of food but it is also good source of income for many smallholder farmers. The Challenges ...

  • From (cyber)space to ground: new technologies for smart farming

    Increased water demand and climate change impacts have recently enhanced the need to improve water resources management, even in those areas which traditionally have an abundant supply of water, such as the Po Valley in northern Italy. The highest consumption of water is devoted to irrigation for agricultural production, and so it is in this area that efforts have to be focused to study ...

  • Salinization/sodification of soil and physiological dynamics of sunflower irrigated with saline–sodic water amending by potassium and farm yard manure

    Sunflower (Helianthus annuus L.) plants were grown with saline–sodic water (SSW) by treating with potassium (K @ 100 and 200 mg K2O kg−1 soil) and farm yard manure (FYM @ 5 and 10% of soil, w/w). Irrigation with untreated SSW caused soil salinization/sodification, leading to an increase in electrical conductivity (EC) of 165% and sodium adsorption ratio (SAR) 100% with ...

  • Farming in a Controlled Environment

    There is considerable pressure on today’s farmers. This is because of farming, as a special type of manufacture, largely depends on climate and natural resources. Climate changes have led to unpredictable weather conditions that can endanger farmer’s efforts with frequent hail, frost or drought. With increased global population, that is predicted to reach a number of 9.6 billion by ...
