Both Macro and Micro Elements are essential for optimal plant growth. Trace elements (micros) are often removed from the soil through years of intensive farming, use of fertilizer, lime application and natural causes. Through the use of Yield Plus Classic and Yield Plus Grain the plant is not only growing and producing at an optimum with a reduction of osmotic and other stress factors from Yield Plus but the micros will ensure there are no shortages of these elements allowing for maximum productivity, yield and quality.

Yield Plus (AATC) observed in plants.

  • Increased survivability under stress conditions
  • Increased drought resistance
  • Reduction of osmotic stress
  • Reduction of temperature stress
  • Reduction of soil and other agronomic stress
  • Reduction of transplant stress
  • Reduction of plant diseases (resistance to rust and other fungi)
  • Accelerated and increased recuperation after stress factors
  • Uniformity of growth
  • Uniformity of crop
  • Increased yield
  • Increased quality
  • Increased shelf life
  • Increased exports and returns
  • Improved base plant development
  • Improved root system
  • Improved foliar growth
  • Improved protein synthesis
  • Improved proline synthesis
  • Greater carbon cell development
  • Greater uptake and utilization of nutrients
  • Improved overall plant vigour
  • Improved fruit set for the following season


As documented in international scientific literature

Plant requirements

(Zn) Zinc

  • Essential for pollen grains enhancing fertilization and fruiting
  • Increases sugar and starch production
  • Essential for the natural production of plant hormones


  • Zinc is a very common deficiency often caused by lime and phosphate applications. (Most notable in citrus)
  • Growth will be poor showing short stems and internodes along with small curled leaves
  • Flowers may be smaller in size
  • Fruit production will be affected

(Mn) Manganese

  • Essential for photosynthesis particularly in sugar production
  • Controls the uptake of other ions and nutrients from the soil


  • A shortage of Mn will result in chlorosis (yellowing) of leaves
  • Leaves become spotted (marble effect)
  • Reduction of flowering and growth
  • Cucumber, beans and many ornamentals are particularly susceptible to this deficiency.

(Fe) Iron

  • Iron produces chlorophyll, (Green leaves) and is therefore essential for photosynthesis, enzyme reaction, growth and development of the plant.


  • Fe shortage results in chlorotic (yellow or white) leaves while the veins may remain dark green.
  • Petioles of tomato plants become purple
  • Standard growth is apparent with crop yields sometimes reduced in excess of 70%

(Cu) Copper

  • Essential for respiration and photosynthesis, greening of leaves, development of flowers, seed production, fruit production and protein development.
  • Copper controls nitrogen fixation by legumes and iron uptake by all plants
  • Increased defence system of plant
  • Helps prevent wilting of leaves during dry osmotic stress periods.


  • Apparent poor leaf colour with deformed leaves and flowers.
  • A reduction in fruit production and quality may be in excess of 50%
  • Citrus may develop abnormal shoots with deformed leaves, fruit with thick oily skins and gum spots

(B) Boron

  • Boron helps reproduction along with seed and fruit set essential when used with Yield Plus
  • Assists in seed, head and ear development of grain plants (as much as 25 - 30%) when used with Yield Plus (Some observed results have exceeded 100%)
  • The diseases resistance in plants is dramatically improved with adequate levels of Boron
  • Root growth and development is greatly enhanced.


  • Shows decreased seed production: a poor flowering and poor fruit set.
  • B deficiency results in deterioration of root and stem growing points, standard roots, wrinkled leaves and hard fruit disease (particularly noticeable in citrus)
  • Crops most effected are grain, cabbage, broccoli, brussel sprouts, cauliflower, carrots, radish and citrus.

(MO) Molybdenium

  • Essential for the sexual functions of the plant and development of embryos
  • Assists in production of and increase of proteins in plants. Also helps with the production of vitamins especially vitamin C
  • A key function in chlorophyll production (greening of leaves)
  • Mo is a key factor to nitrogen fixation by legumes
  • Mo. Protects plants from aluminium toxicity


  • Results in yellow/orange spots on leaves between the veins.
  • "Whiptail" leaf symptoms ie. cabbages etc. and "yellow spot" disease in citrus.
  • Reduction of crop, especially fruit through reduced and small flowers that may not open with deformed reproductive organs. Yield decreases could be in excess of 80%.

(CO) Cobolt

  • Acts as plant catalyst for the uptake of nitrogen therefore essential for all nitrogen related functions in the plant.


  • Reduction in chlorophyll function, protein development, nicotine development in tobacco and all other nitrogen related development factors.
