Marginal value of natural water in agriculture: a study in the suburbs of Mekelle City, Ethiopia
In areas where markets for natural water are lacking, information on its marginal value can be an important tool for proper pricing to achieve efficient allocation of the resource. This article investigates the marginal value of natural water (rainwater used as a proxy) in agricultural crop production in the suburbs of Mekelle City, Ethiopia, by econometrically estimating individual value ...

Biotechnology in developing countries: opportunities in solid state fermentation applied in the agricultural industry
This paper summarises the experiences in Israel and elsewhere of the biotechnological processing of organic matter experiences that could be applied in developing countries. Emphasis is given to relatively simple technologies, and the applications include preservation of forage crops and by-products, mushroom cultivation and recovery of plant cell contents. These technologies might increase milk ...

USGS Study Points To Biofuel Crop Related Land-Use Change Reducing Honey Bee Habitat
On August 29, 2016, the U.S. Geological Survey (USGS) published a study on the result of land-use changes on North and South Dakota commercial honey bee colonies in the journal Proceedings of the National Academy of Sciences. USGS scientists found that grasslands and other landscape features favored by beekeepers were decreasing, with crops that are avoided by beekeepers, such as corn and ...

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 ...

Managing agricultural biotechnology for sustainable development: the case of semi-arid India
Managing agricultural biotechnology for sustainable development demands more than research and intellectual property rights policies. Economic and regulatory institutions conducive to application of intrinsically sustainable technologies are also required. From an interdisciplinary development research perspective, it is argued that sustainability of Indian agriculture and food crop production ...

Scale of biomass production from new woody crops for salinity control in dryland agriculture in Australia
There is scope internationally to utilise surplus and degraded agricultural land for biomass crops that might also be environmentally beneficial. For example, dryland salinity in southern Australian could be ameliorated using profitable woody biomass crops. A model was developed to predict biomass production from such woody crops. At a biomass price of A$35/t (green) and a water use efficiency of ...

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 ...

Analysis of price volatility of mineral fertilisers: possible issues for European farmers
European farmers are currently affected by an increase in the price of fertilisers (from an index of 100 in 2005 to 150 in 2012 after it peaked at almost 200 at the end of 2008) that calls into question the future availability of these kinds of inputs. Since 2007, the strong demand from emerging countries, geopolitical tensions over natural resources, and the rise in the price of energy have been ...

Benefits of fertilizer produced organic fertilizer granulator with chemical fertilizer
The actual utilization rate of chemical fertilizer in many areas is only 30% - 45%, and even lower in some areas! After applying organic fertilizer, due to its beneficial biological activity, the soil structure was improved, the soil water and fertilizer retention capacity was increased, the loss of nutrients was reduced, and the effective utilization rate of chemical fertilizer was increased to ...

An overview of preharvest factors influencing postharvest quality of horticultural products
Postharvest product quality develops during growing of the product and is maintained, not improved by postharvest technologies. Available genetic material allows discrimination of external and internal quality attributes that must satisfy consumer requirements and indulgences. Farmers face challenges in utilising technologies for producing high quality crops; meaningful manipulation of light, ...

Seeding rate and planting arrangement effects on growth and weed suppression of a legume-oat cover crop for organic vegetable systems
Winter cover crops can add soil organic matter, improve nutrient cycling, and suppress weeds in organic vegetable systems. A 2-yr study was conducted on organic farms in Salinas and Hollister, CA, to evaluate the effect of seeding rate (SR) and planting arrangement on cover crop density, ground cover, and cover crop and weed dry matter (DM) with a mixed cover crop. The mix contained legumes (35% ...

To Meet Agtech’s New Movers and Shakers, Look Beyond Buenos Aires
Last November, Arable participated in Silicon Valley Argentina in Rosario, a forum co-organized with Fundación CEDEF, Chacra Media Group, and Silicon Valley Forum. We’ve been to a number of ag shows in the US, and have never seen anything that compares to the caliber of this event. The best part was its forward-thinking focus on ‘the next generation of ag’: It was more ...

So what is the role of commodity programs? Can they even be justified?
No matter what our area of daily activity, it is natural and even necessary that we myopically focus on the problems and issues of the day. But it is also important to step back once in a while to consider how the situations of today fit into a longer-term context. Along that line, we are in the midst of a series of columns that goes beyond the agricultural issues and policy motivations of ...

Glasshouse hygiene - the importance of staying clean
The nature of ornamental crops will mean plants are often in production for a long time, which can result in pest and disease carry over; so, it’s crucial that growers employ a rigorous hygiene and disinfection routine between crops. Start clean Starting the season with remnants of inoculum in the glasshouse, means growers are already on the backfoot, as the growing environment will always ...

Modern Miracles
When a technology comes along that unlocks a new way of thinking about an old problem, we marvel at it as a “modern miracle.” Growing up in Ireland, I know that memories of the Great Potato Famine still run deep. Today, Irish farmers know how fungicides have helped ensure that potato late blight remains a distant memory. Agriculture has come a long way since the nineteenth century, ...

Land application of sugar beet by-products: effects on Nitrogen mineralization and crop yields
Land application of food processing wastes has become an acceptable practice because of the nutrient value of the wastes and potential cost savings in their disposal. Spoiled beets and pulp are among the main by-products generated by the sugar beet (Beta vulgaris L.) processing industry. Farmers commonly land apply these by-products at rates >224 Mg ha–1 on a fresh weight basis. However, ...
