  1. 2020-01-01 In a tropical setting, growing seedlings can be difficult. A major factor of concern for nursery production is water logging (Zhu et al. 2007). During the rainy season, oversaturated soils can effectively suffocate root systems of a seedling by restricting flow of oxygen and other important...  
  2. 2019-10-01 Soil infertility is a key constraint to crop production for small farmers. Soils throughout Sub-Saharan Africa are degraded and deficient in nutrients and organic matter. As a result, there is a growing demand for soil testing services from farmers and NGO staff who want guidance on which inputs...
     
  3. 2019-10-01 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....

  9. 2020-01-01 A comparison trial of winged bean varieties was conducted at the ECHO farm in North Fort Myers (zone 9a/10b), Florida. Seven varieties of winged bean (Psophocarpus tetragonolobus) were evaluated for pod production, pod length, and seed production. Winged bean plants were planted on August 18th,...  
  10. 2020-01-01 Vermicompost contains significant numbers of biological organisms capable of suppressing plant diseases on leaf surfaces. This study, done at ECHO in southwest Florida during the spring of 2011, was conducted to evaluate the potential of foliar-applied vermicompost teas for plant disease...
