Conteúdo: |
In tropical acid soils, acidity is an important constraint for avail-ability and uptake of nutrients by annual crops, and this leads tolower crop yields. Factors that contribute to low nutrient uptakeefficiencies in these soils are low natural levels of most essentialplant nutrients and unfavorable soil and plant environments. HighPfixation capacity, Al, Mn and H toxicity, low activities of bene-ficial microorganisms, soil compaction, infestation of weeds, dis-eases and insects, drought and intensive monoculture are some ofthe major factors that contribute to the unfavorable soil and plantenvironments. Improving nutrient use efficiency in these soils de-mand adoption of special management practices. These practicesinclude timely application of adequate levels of lime, gypsum and fertilizers to meet crop demand, use of proper crop rotation, im-provement of organic matter content, control of soil erosion anduse of acid tolerant crop species and cultivars within species. |
