in the past several decades, using wheat germ has become more prevalent as an alternate way of controlling excess algae growth.
Excessive algae growth is among the most frequent issues occurring in ponds from Pennsylvania. Conventional mechanical and pond algae control systems aren’t always economical or efficient.
In the last few decades, using wheat germ has become more prevalent as an alternate way of controlling excess algae growth. This page summarizes using barley straw according to Dr. Newman’s work and our adventures in Pennsylvania.
When implemented at the appropriate time and speed, barley straw was a really prosperous algae management technique in Pennsylvania ponds.
How does this function?
Barley straw does not kill present algae, but it inhibits the newest development of algae. The precise mechanism is poorly known, but it would appear that wheat germ, when subjected to sunlight and at the presence of oxygen, creates a compound that inhibits algae growth.
In reality, in some instances aquatic plant expansion has grown after wheat germ programs because algae are no more present to contend with plants.
When should it be implemented?
Barley straw is the most effective when implemented early in the calendar year before the appearance of algae (autumn through early spring). When employed to cold water (less than 50°F), it might take six to eight months to the straw to start generating the active compounds that inhibit algae growth.
If the straw is employed to warmer water (over 70°F), it might become successful in no more than one to two weeks. Whatever the situation, wheat straw stays effective for about six months following program.
Just how much straw?
The most frequent program is roughly two to three bales per surface acre of pond (roughly 10 to 25 g of hens per square meter of pond area). The depth of water at the pond isn’t important. In ponds which are often muddy or the ones which have a history of significant algae growth, a couple of instances this recommended dose could be required for your first therapy.
But, overdosing the pond using barley straw might lead to fish kills since the straw oxygenates the water since it decays. This is particularly an issue if the pond is overdosed with straw through a protracted warm spell.
