Plant-Prod 20-10-20, water soluble fertilizer has 60% of its nitrogen in the nitrate form, and a complete minor elements package including a higher level of molybdenum, as required for soilless mixes. This is an ideal formulation for use in low light conditions.
Plant-Prod 18-6-20 water soluble fertilizer contains over 60% of the nitrogen in the nitrate form, a high level of magnesium, an increased level of molybdenum, a low boron level and chelated micronutrients.
Plant-Prod 15-30-15 water soluble fertilizer is ideal for hydrangeas since the high phosphorus content ties up excess aluminum in the soil which causes a strong pink colouration in the blooms. Acid-loving plants such as african violets respond well to this formulation due to its high potential acidity. Use during the early stages of crop growth, when many greenhouse crops require extra phosphorus, particularly tomatoes and cucumbers grown in soil. 15-30-15 can be used to remedy phosphorus deficient soils.
Plant-Prod 15-15-30 is a water soluble fertilizer that supplies twice as much potassium as nitrogen, while still maintaining the optimal levels of the other plant nutrients. Over 58% of the nitrogen is in the nitrate form. It has a very low potential acidity, exhibiting minimal acidifying tendencies in the soil. It is recommended when soil levels or tissue samples show low potassium levels or when plants are setting bud, as well as during maturation and blooming.
Plant-Prod 15-0-15 is a completely water soluble prilled fertilizer mixture of calcium nitrate, potassium nitrate and micronutrients. With over 90% of the nitrogen in the nitrate form and no urea, Plant-Prod 15-0-15 is very effective under low light conditions. With a relatively high potential basicity this formula can be used to raise media pH. Prilled form improves product flowability.
Plant-Prod 14-0-14 is a water soluble prilled fertilizer formulation useful whenever additional calcium and magnesium are required. commonly used in rotation with 20-8-20 but also excellent for plug production. Plant-Prod 14-0-14 contains a complete micronutrient package including high molybdenum and over 90% of the nitrogen is in the nitrate form.
Calcium to magnesium ratio is 2:1.
Zinc plays an important role in the utilization of other plant nutrients. Deficiencies commonly occur in sandy soils, soils low in organic matter or where phosphates have been excessively applied. Plant-Prod Chelated Zinc Fertilizer 14% can be used to correct such deficiencies.
The availability of copper is influenced by pH, the amount of organic matter and the presence of other metallic ions such as iron or magnesium. Deficiencies can appear as chlorosis, wilting and dieback of stem and twigs. Plant-Prod Chelated Copper Fertilizer 14% can be used to correct such deficiencies.
Iron deficiency is a problem in several crops particularly in conditions of high pH. Plant-Prod Chelated Iron Fertilizer 13.2% is an efficient source of iron to correct iron deficiencies.
Manganese deficiency results in reduced photosynthetic activity. Conditions of high pH, low organic matter or sandy soils will reduce the availability of manganese. Plant-Prod Chelated Manganese Fertilizer 13% can be used to correct such deficiencies.
