  2. An Introduction To Soil Fertility

    Sumber Daya Utama
    20 Januari 2009 All plants need certain mineral elements for proper growth, development, and maintenance. The basic structure of all organisms is built of carbon (C), oxygen (O) and hydrogen (H). Plants obtain these elements from water (H2O) in the soil and carbon dioxide (CO2) in the air, so no input is...

  3. Acidic soils of the Tropics

    01 Oktober 2019 Acidic soils are soils with a pH lower than 7. For most plants, having a pH between 6 and 7.5 is ideal (see table 1 for more exact numbers), but soils can become dangerous when their pH drops beneath 4.5. As the pH drops, aluminum becomes more soluble, toxifying the soil and harming the plants....

  4. Soil acidity and liming.

    01 Januari 1984 Excessive soil acidity is a continuing problem in many agricultural areas and is increasingly becoming a yield-limiting factor in other areas. The pH of soils of the dryland wheat-growing area of the Pacific Northwest has dropped an average of one unit in the last 20 years. Similar effects are...

  5. Terra Preta: the Secret of Rich, Dark Soil in the Amazon

    20 April 2004 Terra preta is very productive soil with long-lasting fertility—unusual in the tropics, where most soils are very weathered, highly acidic, and low in organic matter and essential nutrients. The key to terra preta soils long-term fertility seems to be charcoal; terra preta contains up to 70 times...

  6. Soil pH Buffering Capacity and Nitrogen Availability Following Compost Application in a Tropical Acid Soil

    ABSTRACT - Journal of Composting Science and Utilization, 2017 Tropical acid soils are highly weathered as they exist under tropical environment with high rainfall and temperature throughout the year, which affects nitrogen availability. Soil organic nitrogen is important in estimating soil...

  7. The Effect of Aluminum in Acidic Soils on Plant Growth

    20 April 2001 Soil acidity, or low pH, limits plant growth in many parts of the world. Although low pH can harm plants in many ways, this article will deal only with one of these factors, aluminum (Al) toxicity.Al is the third most abundant element on the earth (after oxygen and silicon), and the most abundant...

  8. Nutrient Quantity or Nutrient Access? A New Understanding of How to Maintain Soil Fertility in the Tropics

    20 Januari 2002 The conventional view of the relationship between soil nutrients and crop productivity in the tropics is leading to both damaging agricultural policies and inefficient and damaging farm-level practices. There is no need to use the huge quantities of chemical fertilizers that are so often...
