  • 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 ...

  • Enzyme activities and litter decomposition in agricultural soils

    Although enzyme activities were extensively investigated in soils with reference to abiotic environmental conditions and human impact, their role in litter decomposition is not fully understood. Therefore, decomposition rates and enzyme activities were studied using nylon bags and three litter types buried in silty-loamy Cambisols and Luvisols in northern, central and southern Germany under ...


  • Soils, souls and agricultural sustainability: the need for connection

    Sustainability is a contested term, and has much in common with justice and liberty in meaning very different things to different people. Typically it is the vision of the developed North that has dominated. This paper describes some of the results of a long-term research project based in Kogi State, Nigeria, designed to explore agricultural sustainability, and in particular how a Northern-based ...

  • Persistence of the tricyclic antidepressant drugs amitriptyline and nortriptyline in agriculture soils

    Amitriptyline and nortriptyline are widely‐used tricyclic antidepressant drugs. They have been detected in wastewater, surface runoff, and effluents from sewage treatment plants. As such, they could potentially reach agriculture land through the application of municipal biosolids or reclaimed water. In the absence of data on their fate in the environment, the persistence and dissipation ...

  • 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 ...

  • Introduction of composted digestates in agriculture

    Municipal organic waste is increasingly recycled by aerobic composting or anaerobic digestion procedures. In 1997, 230 000 Mg organic waste were composted and used for agriculture in the region of Cologne, which is an increase by 70% compared to 1994 (Anonymous, 1999). Therefore, the effects of compost on the soil and the plants require studies on:- its nutrient contents to contribute to the ...
