high potassium and phosphorous blend...
Potassium deficiency is quite common in intensive agriculture and
horticulture. Potassium salts are usually soluble and move with
moisture through the soil. Although often a considerable percentage
of the potassium is present in the soil, it can be locked up in
solid rocks and minerals, and some is not freely available as it is
trapped in clay layers. The portion trapped in clay is often
referred to as “slowly available” potassium. It is slowly released
into the soil moisture over a period of years but the rate is highly
variable and is influenced by the soil moisture and the chemical and
physical nature of the clay.
Sufficient potassium is essential for growth and a deficiency
results in stunted growth and reduced yields. The exact function of
potassium in plant growth is not completely clear but it improves
resistance to disease and insect attack, stimulates growth,
particularly early growth and is associated with movement of water,
nutrients and products of photosynthesis in plants. The easiest and
probably most reliable way to determine if the available potassium
is sufficient is from soil tests. If the level is below 80 ppm then
the crop is likely to be adversely affected. (Standard soil tests
measure only the available potassium... not any that is locked up in
rocks etc).
The amount available and easy of uptake of potassium is influenced
by a number factors such as soil moisture, soil temperature and soil
aeration. No-till agriculture may reduce the amount of potassium
because of decreased root growth. Unlike the other macronutrients,
phosphorus and nitrogen, excess potassium does not appear to have
any detrimental effects on plants. High Potassium is designed as a
foliar feed and contains soluble phosphorus and a small amount of
nitrogen and sulfur all in a readily available form. Being a foliar
fertilizer most of the potassium in the product gets into the plant
and is immediately available if applied correctly. The product
contains no chloride so its use avoids the problems associated with
high chloride fertilizers such as muriate of potash.
When applying the product a fine spray should always be used where
possible. If a coarse spray is used it is recommended to dilute with
additional water. Leaf burn should not occur provided the product is
applied when the temperature is below 25 degrees C.
Since leaf burn is more likely to occur when the humidity around the
leaf is low, it is prudent to spray later in the day when the
temperature is likely to fall and the humidity is likely to
increase.
High Potassium Foliar feed is not a balanced fertilizer but designed
to be used as a foliar feed to minimize the effect of a soil
potassium deficiency or to supply additional potassium when there is
high demand. It can be used as a soil drench but in high rainfall
areas a significant amount of potassium may be washed out of the
soil.
High Potassium may be tank mixed with Superfine, Premium, Spurt or
Quick Grow.
The water and High Potassium should be added to the tank first then
Premium, Spurt or Quick Grow added.
Application
Mix 1 part High Potassium with at least 7 parts water.
On pasture High Potassium can be used up to 15 ltrs p/Ha and may be
repeated every 4-6 weeks.
