  • IDHA chelates as a micronutrient source for green bean and tomato in fertigation and hydroponics

    The new biodegradable chelating agent imidodisuccinic acid (IDHA) has been studied for its application in agriculture. This study was conducted to compare the efficiency of mixed IDHA and ethylene diamine tetraacetic acid (EDTA) formulations to provide Fe, Mn, Zn, and Cu to green bean (Phaseolus vulgaris ‘Perfección negra polo’) and tomato (Lycopersicum esculentum Mill. ‘Shiren’) plants grown in ...

  • Distribution of arsenic and other minerals in rice plants affected by natural straighthead

    Because of the inconsistency and unpredictability of naturally occurring straighthead, arsenical herbicides are sometimes used to induce straighthead-like symptoms to study this sterility disorder. In 2005, an outbreak of naturally occurring (nonchemically induced) straighthead in rice (Oryza sativa L.) study fields in Stuttgart, AR provided an opportunity to examine the role of minerals in this ...

  • Uses of winery and distillery effluents in agriculture: characterisation of nutrient and hazardous components

    ABSTRACTTwenty-one samples of winery and distillery effluents were collected from different Spanish winery and distillery industries. Electrical conductivity, pH, redox potential, density, organic charge (chemical oxygen demand, biological oxygen demand, total, volatile and suspended solids, oxidisable organic C and polyphenols) and contents of plant nutrients and heavy metals were analysed. The ...

  • Effect of compost-, sand-, or gypsum-amended waste foundry sands on turfgrass yield and nutrient content

    Received for publication July 19, 2008. To prevent the 7 to 11 million metric tons of waste foundry sand (WFS) produced annually in the USA from entering landfills, current research is focused on the reuse of WFSs as soil amendments. The effects of different WFS-containing amendments on turfgrass growth and nutrient content were tested by planting perennial ryegrass (Lolium perenne L.) and tall ...

  • Benefits of composting at home

    There are a lot of ways that we can take part in helping save the environment. Ways include water management, smart shopping, fuel efficiency and recycling. However, the most environmentally valuable action that we can all take part is composting.

  • Vermicompost’s Role in Farming

    One of the main goals of every organic farmer is to build long-term soil fertility and tilth by feeding the soil with a variety of natural amendments. The regular addition of compost is one of the best ways to enhance the soil’s organic and humic content, which helps to build a fertile soil structure. This soil structure makes better use of water and nutrients. It is easier to till and, ...

  • Knowledge of Farm Practices – The Key for Successful Farming

    Agriculture plays an important part in the world economy. One-third of the economically active population obtains its livelihood from agriculture. In Asia and Africa, millions of small-scale farmers, fishermen, and indigenous people produce most of the food consumed worldwide, in most cases on very small plots of land. Agriculture is increasingly called upon to address a wide range of critical ...

  • 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 ...

  • Connections: New Green Revolution

    We are in need of a new revolution in how food is grown. A growing population in combination with climate change has put heavy pressure on our current system. The last time this happened (about 50 years ago) we had the Green Revolution to save the day. Major improvements in crop breeding and the use of synthetic fertilizers and pesticides resulted in enormous yield gains in farms across Asia, ...

  • Evaluating Microbiology of Compost

    The fact that not all compost is created equal has both producers and growers looking for ways to successfully evaluate compost quality. Traditional compost analysis has focused on NPK and micronutrient concentrations in an effort to mirror fertilizer analysis. Compost, however, is much more complex than fertilizer and its most significant value to the grower may be far more than its mineral ...

  • Science’s role in growing diverse, nutritious food

    Can science meet the demand for more diverse and nutritious food? Jan Piotrowski investigates. The riots that swept Africa in 2007 and 2008 in response to the spiralling costs of staple crops brought the effects of food shortages into sharp focus. Images of unrest circled the globe, and the consequent instability brought to the forefront of political debate a question that had ...

  • What is the Future of Horticultural Science in Africa?

    Horticulture is a labour intensive sector that is important for human wellbeing: 'agriculture supplies protein, carbohydrates and staple crops - but we would have a pretty boring life without horticulture.' Nevertheless, in many countries, faculties of agriculture and their departments of horticulture have been swallowed by schools of life or earth sciences. As a result horticulture gets ...

  • Creating a Sustainable Food Future: Interim Findings - A menu of solutions to sustainably feed more than 9 billion people by 2050

    The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who depend on agriculture for their livelihoods, and reduce environmental impacts, including ecosystem degradation and ...
