Tropical lowland regions are characterized by high humidity and annual rainfall. Lowlands exist around the world in microclimates but predominate areas of South and Southeast Asia, Latin America and Caribbean, and Coastal regions of the tropics. One of the main agricultural concerns for lowland regions is dealing with waterlogged soils and related plant pathogens.



  1. 1997-11-19 Principles for increasing organic matter in order to increase soil fertility. Little by little, work in a dozen countries has convinced us that the vast majority of soils can be made highly fertile. How? By using our first principle:maximize organic matter production.
  2. 关键资源 2015-09-21 The System of Rice Intensification (SRI) is a method of raising rice that produces substantially higher yields with the planting of far fewer seedlings and the use of fewer inputs than either traditional methods (i.e., flooding) or more “modern” methods (using mineral fertilizer or...
  3. 2020-08-31 Tomatoes are difficult to grow during Southeast Asia’s hot and humid monsoonal rainy season.

  7. 2019-02-15 This article is from ECHO Asia Note # 37. 可持续农业最大的挑战之一就是如何将充足且价格实惠的有机资源(碳基)用于食物和饲料生产。利用堆肥、肥料、覆盖物和其他来自农业的有机投入本身就是一个挑战,而且每一种生产往往都需要自己特有的投入材料。有的材料在农业生产中常常是有直接竞争关系的,完全供应给土地小和劳动力少的农场是有挑战性的。例如,地膜可能与牲畜饲料直接竞争,因此在生产足够地膜的同时喂牲畜是一个挑战。使用同样的材料来制造堆肥或燃料就更有挑战性了。 在访问了该地区许多不同的小规模农场后,最成功的农场似乎都有一个共同的方法,那就是找出一种容易获得的有机...
  8. Farm-generated fertility makes agriculture more sustainable. Crop residues and manures are part of the nutrient cycle and can lower input costs through the use of thermophilic composting, vermiculture, bokashi production, or green manures. Farm-generated feeds can also reduce expenses, if farmers...
  9. 2015-08-01 As densities of livestock increase, an industrious farmer finds ways and means to increase his farm’s nutrient stream for the benefit of his system.
