Assessment of climate change impact on crop yield and irrigation water requirement of two major cereal crops (rice and wheat) in Bhaktapur district, Nepal
Rice and wheat are major cereal crops in Nepal. Climate change impacts are widespread and farmers in developing countries like Nepal are among the most vulnerable. A study was carried out to assess the impact of climate change on yield and irrigation water requirement of these cereal crops in Bhaktapur, Nepal. Laboratory and soil-plant-air-water analysis showed silt-loam being the most ...

Modeling the impact of nitrate fertilizers on groundwater quality in the southern part of the Nile Delta, Egypt
The use of fertilizers in agriculture in Egypt, especially nitrogen, has increased significantly in the last decade, resulting in nonpoint contamination of the groundwater resources. This study investigated the effect of using nitrogen fertilizer on groundwater contamination with nitrate in the central southern part of the Nile Delta. NO3− concentrations in shallow groundwater were assessed ...

Opportunities to Generate Cash Flow for Family Forests Using Conservation Payments
There has been significant discussion about the merits of stacking conservation payments over the past few years. A simple explanation for credit stacking is when landowners are paid for conservation practices on their property that provide multiple benefits to the environment. Examples of credits types that might be stacked include: endangered species, water quality, wetlands, and carbon. ...

Is Water RunOff Effecting my Pond?
What is Water RunOff? Runoff is precipitation that did not get (infiltrated) absorbed into the soil, or did not evaporate, and therefore made its way from the ground surface into places that water collect. Runoff causes erosion, and also carry chemicals and substances on the ground surface along to the ponds, lakes and rivers where the water ends up. (eschooltoday.com) Phosphorus and Nitrogen ...

Fecal sludge-derived pellet fertilizer in maize cultivation
Fecal sludge (FS) contains significant amounts of plant nutrients and organic matter although it also contains pathogens. Therefore, FS can be used as fertilizer after proper sanitization. This study was designed to test dried fecal sludge (DFS)-based pellet fertilizers on maize cultivation. The DFS fertilizers were produced by composting, co-composting with sawdust, or irradiated by ...

Soil Moisture Terminology
Soil Moisture Terms. What do they mean and how do we use them? By the end of this short article you will hopefully understand the following statement. “For good crop growth, maintaining water above stress point will maximise vegetative growth. Setting a refill point above stress point will ensure there is always readily available water for the crop. Replacing ...

Influence of nitrogen fertilizer on Cd and Zn accumulation in rapeseed (Brassica napus L.) biomass
Diffuse soil contamination with heavy metals and Cd in particular is a matter of serious concern. Application of conventional remediation methods usually is not feasible due to the large territories and relatively low heavy metal content. Thus, phytoremediation is seen as an alternative. Rapeseed was grown on Cd and Zn contaminated as well as clean soil under the greenhouse conditions. Solid and ...

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 ...

One crop, two ways, multiple benefits
Nitrogen fixation is one of the best examples of cooperation in nature. Soil microbes – naturally occurring bacteria in the soil – work with plants to pull nitrogen from the air. They turn the nitrogen into a form the plant is able to use. In return, the plant lets the microbes eat some of the sugars it makes. Faba beans (also called fava beans) are one example of plants that work ...

The farmers' perceptions of ANPS pollution and its influencing factors in Poyang Lake Region, China
Individual farmers represent the main management entities of agricultural production under the family-contract responsibility system in China, and thus play crucial roles in the prevention and control of agricultural nonpoint source (ANPS) pollution. The analysis of the farmers' perceptions of ANPS pollution as well as the factors affecting their perceptions can provide valuable information ...

Sustainable Soil Health
“A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing population of the world. However, ...

The complex nature of GMOs calls for a new conversation
An honest discussion of genetically modified organisms must move beyond narrow concepts of human health to the wider social and environmental impacts of engineered crops. The GMO debate is one from which I’ve kept a purposeful distance. For one thing, it’s an issue that has already garnered more than its fair share of attention. For another, when you consider that many domesticated ...

Phosphorus runoff is a big problem, but Florida is getting closer to a solution
Excess phosphorus runoff and emissions from urban areas and croplands, animal feedlots, sewage treatment plants, and combustion of fossil fuels has been blamed for the dead zone in the Gulf of Mexico, toxic algal blooms in Lake Erie and problems in numerous other lakes and rivers around the world. For years unwanted nutrients were also choking the Florida Everglades, but in a surprising ...

How to grow more food with less water
Scientists and farmers collaborate on a quest for more efficient irrigation This story was co-published with Civil Eats, a daily news source for critical thought about the American food system. From reading the weather to choosing a crop, farming has always been a hands-on enterprise. When a farmer wonders how much water a crop needs, a simple test has always sufficed: Grab a handful of soil ...

LIVE FROM THE NCRS: Yet Another Busy Day at the NCRS
So yesterday (Wednesday Jul 22, 2015) was another busy day to take advantage of the nice weather. Like moving the wheat harvest operation over to Farm 7. OK, this is pretty lame. But you have to admit that the chrome on the back of the grain trailer is kept pretty shiny. (See what happens when you go from researcher to management!) Over in the orchard the crew is continuing the ...

Transition of fertilizer application and agricultural pollution loads: a case study in the Nhue-Day River basin
Rapid socio-economic development in suburban areas of developing countries has induced changes in agricultural waste and nutrient management, resulting in water pollution. The study aimed at estimating agricultural nutrient cycles and their contribution to the water environment. A material flow model of nitrogen (N) and phosphorus (P) was developed focusing on agricultural activities from ...

Evaluation of climate change impacts and adaptation strategies for maize cultivation in the Himalayan foothills of India
This study evaluates the impacts of climate change on rainfed maize (Zea mays) yield and evaluates different agro-adaptation measures to counteract its negative impacts at Sikkim, a Himalayan state of India. Future climate scenarios for the 10 years centered on 2025, 2055 and 2085 were obtained by downscaling the outputs of the HadCM3 General Circulation Model (GCM) under for A2 and B2 ...
