  • Ramial Chipped Wood: the Clue to a Sustainable Fertile Soil

    Close to forty percent of the world's agricultural land is seriously degraded, which could undermine the long-term productive capacity of those soils. Plus, the economic and social effects of agricultural land degradation have been much more significant in developing countries than in industrialized countries. However, they are the regions where the greatest growth in food production will be ...

  • Manioc peel and charcoal: a potential organic amendment for sustainable soil fertility in the tropics

    In tropical areas, where crop production is limited by low soil quality, the development of techniques improving soil fertility without damage to the environment is a priority. In French Guiana, we used subsistence farmer plots on poor acidic soils to test the effect of different organic amendments, bitter manioc peel (M), sawdust (Sw) and charcoal (Ch), on soil nutrient content, earthworm ...

  • 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 ...

  • Synthetic nitrogen fertilizers deplete soil nitrogen: a global dilemma for sustainable cereal production

    Received for publication December 19, 2008. Cereal production that now sustains a world population of more than 6.5 billion has tripled during the past 40 yr, concurrent with an increase from 12 to 104 Tg yr–1 of synthetic N applied largely in ammoniacal fertilizers. These fertilizers have been managed as a cost-effective form of insurance against low yields, without regard to the inherent effect ...

  • Sugarcane response to mill mud, fertilizer, and soybean nutrient sources on a sandy soil

    Improving soil organic matter and soil fertility are important factors in the sustainability of sugarcane (Saccharum spp.) production. A 3-yr field trial was established in 2004 on a sandy Alfisol in Florida to compare the effect of organic and inorganic nutrient sources on sugarcane production. The three nutrient sources were (i) mill mud (filter cake, cachaza), (ii) local standard fertilizer, ...

  • Analysis of Organic Fertilizer Market

    Organic fertilizer is processed by fermenting the animal and plant residues, it not only contains major elements that plant required such as nitrogen, phosphorus and potassium, also contains microelements such as molybdenum, zinc, iron, copper and other trace elements which is ...


  • Creating a sustainable food future, installment three: Achieving replacement level fertility

    The world’s population will rise from just over 7 billion in 2012 to nearly 9.6 billion by 2050. Most of the world’s regions have already achieved or are close to achieving replacement level fertility. “Replacement level fertility” is the total fertility rate—the average number of children born per woman—at which a population exactly replaces itself from one ...

  • Soil management practices for sustainable agro-ecosystems

    A doubling of the global food demand projected for the next 50 years poses a huge challenge for the sustainability of both food production and global and local environments. Today’s agricultural technologies may be increasing productivity to meet world food demand, but they may also be threatening agricultural ecosystems. For the global environment, agricultural systems provide both sources and ...

  • Agricultural Management Practices to Sustain Crop Yields and Improve Soil and Environmental Qualities

    Increasing crop production to feed the growing population was a major challenge to the agricultural community in the past few decades. As a result, management practices consisting of intensive tillage and high rate of fertilization were used to increase crop production. While these practices increased crop production by severalfold compared with less intensive tillage and no fertilization, little ...


  • Losing Soil

    In 1938, Walter Lowdermilk, a senior official in the Soil Conservation Service of the U.S. Department of Agriculture, traveled abroad to look at lands that had been cultivated for thousands of years, seeking to learn how these older civilizations had coped with soil erosion. He found that some had managed their land well, maintaining its fertility over long stretches of history, and were ...

  • Extension workers' attitude towards usefulness of an integrated soil fertility and nutrient management approach in Bangladesh

    The main focus of this study was to determine extension workers' attitude towards usefulness of Integrated Soil Fertility (ISF) and Nutrient Management (NM) approach for sustainable crop production. Data were collected from 64 extension workers from four districts in Bangladesh using face-to-face interview from December 2005 to January 2006. Findings indicated that more than two-thirds (68%) of ...

  • Fertilization management of paddy fields in Piedmont (NW Italy) and its effects on the soil and water quality

    The fertilization management of the rice crop in Piedmont was analyzed at a regional scale, and the agronomic and environmental sustainability of the actual fertilization strategy of rice was evaluated through the analysis of its effect on the soils and waters quality. On average, a total amount of 127 kg ha − 1 of N, 67 kg ha − 1 of P 2 O 5 and 161 kg ha − 1 of K 2 O were ...

  • Crop rotation and nitrogen input effects on soil fertility, maize mineral nutrition, yield, and seed composition

    Knowledge of complex relationships between soils, crops, and management practices is necessary to develop sustainable agricultural production systems. Objectives were to determine how maize (Zea mays L.) would respond to monoculture (C-C), 2-yr rotation (C-S) with soybean [Glycine max (L.) Merr.], or 4-yr rotation (C-S-W/A-A) with soybean, wheat (Triticum aestivum L.), and alfalfa (Medicago ...

  • Long-term fertilizer experiment network in China: Crop yields and soil nutrient trends

    Results are summarized for the first 15 yr of an eight-site, long-term experimental network in China designed to assess the sustainability of cropping systems in environments representing 70% of Chinese cropland. Systems were wheat–maize double cropping (two crops per year) at four sites, wheat–rice double cropping, rice-based triple cropping, and wheat or maize single cropping. Without ...

  • Wastes as fertilizer – Is this a way to lower food costs?

    Researchers in the UK think they may have found a way to produce fertilizers that should cut farmers’ costs and at the same time boost some types of renewable energy. Their scheme, which involves using waste material from anaerobic digesters and ash from burnt biomass, would also cut fossil fuel use and save natural resources. ...

  • Microorganisms as indicators of soil quality

    If we are to monitor soil quality, we need indicators of trends and changes. In order to choose relevant indicators, we must understand the factors controlling soil quality. Soil quality is dependent upon the physical, chemical and biological soil components. The interaction between these components is complex. The chemical and physical components have been more fully investigated than the ...

  • Local fertilizer manufacturing: A new look at agro-business

    The American farmer works in a tough business. Aside from the demanding physical and mechanical processes to raise fertile crops from tiny seeds, the farmer must also battle against supply for adequate water, the right seeds, pest and weed control products, and various fertilizers. All these elements have added stress and cost to bring a crop to market, making it less profitable than ever to ...
