FERTILIZER RECOMMENDATIONS

      Soil Type

      Cucumbers are adapted to a wide variety of soil types which have good                 drainage and adequate soil-holding capacity.

        Optimum pH


   Cucumbers don't perform well on acid soils but do well under slight acidity. The optimum pH is 5.5-7.0. In general, if the soil pH is below 5.8 and the available soil calcium is less than 2,000 lbs. per acre, apply 2,000 lbs. per acre (4.5 lbs./100 square feet) of agricultural lime 8 to 12 weeks before planting. However, some Hawaiian soils may require considerably more lime. Liming to a pH of 7.2 to 7.5 plus the use of nitrate-nitrogen fertilizer sources help to reduce incidence of Fusarium wilt, Fusarium oxysporum in the field. Micronutrient availability may be reduced at a pH above 6.5.
