Steady N
The ingredients in Steady N stimulate microbial activity within the soil, which hold nitrogen in the soil for longer leading to greater nitrogen efficiency and therefore better yields and greater productivity.
SprayMate
SprayMate is Southern Humates liquid humate that contains the three main ingredients of humate: Carbon, Fulvic and Humic. As well as feeding beneficial organisms in the soil, SprayMate reduces the amount of water required for crop production.
The trial showed conclusively that the addition of Southern Humates lifted both the beneficial fungi and bacteria levels.
Most notably, however, was the dramatic increase in the total fungi and active fungi.
The desired ratio of active fungi to active bacteria in pasture is 1:1. Our trial showed that the addition of humate was beginning to bring this back into balance after only six weeks, through activating the existing fungi as well as multiplying total fungi levels.
Case Studies
North Island fruit growers reaping rewards
John Thomas, has a wide range of pasture and crop experience including growing maize and owning a kiwifruit orchard. John also furthered his hands-on knowledge and undertook study in the USA to become a qualified agronomist.
Having worked with humates for more than 15 years, he could be described as one of the early innovators of its use in New Zealand.
John’s work with the avocado industry in particular has proven to be extremely successful. Growers are reportedly ecstatic with the increased yields from using humates which allows them to fruit annually as opposed to biannually using a naturally occurring, chemical-free product to energise their avocado plants.
South Island farms and vineyards seeing benefits of humates
Canterbury-based biological farming and soil fertility consultants, Top Soils, have seen positive results from Southern Humates.
Don Hart is the founder and CEO of Top Soils in Methven, which specialises in soil fertility programmes for all soils and farming operations. Top Soils balance soil nutrients using the Kinsey-Albrecht system of soil fertility. The company uses fertilisers that are not harmful to soil health, soil life and plant roots, and add humates to fertilisers to buffer and increase the efficiency of the fertilisers. The addition of humates with fertilisers increases the percentage of applied nutrients passing through the root cell wall.
“Southern Humates have been supplying us with quality humates for the last three years. We include humates in all our fertiliser blends and aim to have at least 10% of the fertilisers used in the form of humates.”
Southern Humates preferred by soil and fertiliser specialist
Independent biological soil and fertiliser consultant, Jeff Broomfield, has used humates for the last 15 years within his farm fertiliser programme, applying humate at rates of 3-5% by volume to all fertiliser applications. He believes he has seen the benefits and efficiencies of the fertilisers used.
“Over the last seven years we have lifted Ca base saturation from 40% to close to 65% using 4-5 tonnes of agricultural lime applied; theoretically we should have used 9-10 tonnes to achieve this result. The trend for production is approximately 3-4% annual increase, as the block is used as a cut and carry operation and all grass has been weighed and dry mattered.”
Broomfield has been recommending the use of humates to his clients on a similar basis to his own farming operation. These clients range from intensive dairy, sheep (dryland and irrigated) and cropping to extensive pastoral grazing on hill country throughout the lower South Island.
“To date, crop yields have been more consistent, applications of urea with humate have appeared to grow more grass, animal health has improved and there have been less urine patches observed.”
Broomfield’s fertiliser programmes are all designed to create a stable and biologically friendly environment; he strongly believes that humates have helped to achieve these successes.
The successes that he has observed on these various farming operations are similar to the results from the Southern Humates trials, where production from a conventional product increased by more than 30% when humates were added to it.
“Until now we have had only farmer observation and the belief that humates will create better efficiencies with our fertiliser programmes, now these observations are supported by science.”
