Soils often become deficient due to their inherent physical problems or by the addition of other products, creating a chemical imbalance.
IDENTIFYING SPECIFIC NUTRIENT DEFICIENCIES Trace Elements Deficiencies On new growth and young leaves Normally occur under alkaline (high pH ) conditions Iron Manganese Zinc Major Nutrient Deficiencies On lower or older leaves Normally occur under acidic (low pH) conditions Magnesium Phosphorus Potassium Nitrogen IRON DEFICIENCY Symptoms are typically the yellowing of top fresh leaves with veins remaining green. Manutec Iron Chelate EDTA is fast acting, high analysis product that performs well even under alkaline soil conditions. Manutec Iron Sulphate is also high analysis economical source of Iron, but is not as effective under alkaline conditions. Iron Sulphate is also a soil acidifier and helps in the controlling of moss. ZINC & MANGANESE DEFICIENCY Symptoms are typically the yellowing of top fresh leaves with veins becoming pale green. In severe cases, this results in little or bunch leaves. Manutec Zinc & Manganese is an easy to use, high analysis, soluble product - providing a quick remedy. MAGNESIUM DEFICIENCY Symptoms are similar to that of Iron (interveinal yellowing) but is seen in the older, matured leaves. Manutec Epsom Salt (Magnesium Sulphate) is a high analysis and fast acting product - providing a quick remedy. Easy to use, highly soluble and value for money. COPPER DEFICIENCY Symptoms similar to that of Zinc with interveinal yellowing in young or fresh leaves with pale green veins. Under severe deficiency, the die off of leaf tips can be seen. Manutec Copper Sulphate is high in analysis, easy to mix into a solution, and fast acting providing a quick remedy. BORON DEFICIENCY Symptoms commonly occur at the very tips of plants with the discoloration of leaf buds and die back. Deficiency symptoms are also evident in fruit or produce - such as "brown heart" in Cauliflower, brown spots in apples/pears etc. Manutec Boron is high in analysis, fast acting - providing a quick and easy remedy. POTASSIUM DEFICIENCY An initial deficiency symptom is the scorched leaf margins/leaf edges. A continual deficiency results in the poor colour, reduced size and yield quantity of Flowers and Fruits. Manutec Liquid Potash Plus is fast acting providing both Potassium & Phosphorous to enhance flowering & fruiting.

Sandy soils (with poor water & nutrient holding capacity) and soils where organic manures have been excessively used, are prone to deficiencies. In particular Potassium & Trace Elements. In alkaline soils (affected by salts/lime), plants are unable to absorb all available nutrients and this triggers lime induced trace element deficiencies of Iron, Manganese, Zinc etc. In acidic (low soil pH) conditions, this commonly triggers deficiencies of major nutrients such as Nitrogen, Phosphorus, Potassium, Calcium & Magnesium. Soil pH & nutrient availability Acidic Low Soil pH MdaejCfoirrceiNeauntetcrsiieesnt Neutral Optimum pH range for plant growth Nitrogen Phosphorous Potassium Sulphur Calcium Iron Manganese Magnesium Boron Copper and Zinc Molybdenum Alkaline High Soil pH Creates deEfilTcerimaecneecnites The above chart shows how Soil pH directly effects nutrient availability and uptake. All the nutrients are easily available in the neutral pH range of 6-7. Hence it is most important to regularly check and correct your soils pH. TRACE ELEMENTS MIX Manutec has a range of high analysis soluble Trace Element products to correct specific deficiencies. If unsure of a specific issue, try our unique product Trace elements.
