  • Soil Fertility: QUEFTS and Farmers’ Perceptions Free to Non-OECD Countries

    Soil fertility is one of many factors influencing farmers’ choices regarding agricultural production, fertilisation and soil and water conservation. However, before we can study the effects of soil fertility, we need to measure it. We use the QUEFTS model (Quantitative Evaluation of the Fertility of Tropical Soils Janssen et al, 1990) which ...

  • Agricultural Chemicals and the Environment

    Enormous increases in agricultural productivity can properly be associated with the use of chemicals. This statement applies equally to crop production through the use of fertilizers, herbicides and pesticides, as to livestock production and the associated use of drugs, steroids and other growth accelerators. There is, however a dark side to this ...

  • Isotopic Studies of Azolla and Nitrogen Fertilization of Rice

    Nitrogen is the most limiting element for crop production. Traditionally, expensive commercial fertilizers are used to correct soil nitrogen deficiencies. Indeed, 50% of the increase in rice yields after World War II can be attributed to increased fertilizer nitrogen use. Although an increased rate of fertilizer nitrogen application has been ...

  • Improving Efficiency of Urea Fertilizers by Inhibition of Soil Urease Activity

    This book is a comprehensive and updated review of fundamental studies on inhibition of soil urease activity and of applied studies on improving efficiency of urea fertilizers by inhibition of soil urease activity. The general literature on these topics covers 65 years and the patent literature comprises a period of nearly 40 years. The potential ...
