S.J.B.
AG-NUTRI is an Australian liquid fertilizer company formed by Steven
Brooks in 1989. Having already worked as an Area Manager and Agronomist
with a large distributor of agricultural products for 6 years prior,
Steven saw the potential and demand for a quality range of liquid
fertilizers formulated specifically for Australian agriculture. In
conjunction with Geelong Agricultural Laboratories, Steven designed a
range of chelated nutrient liquid fertilizers.

The liquid
fertilizers or 'Prescribe Mixes' were first manufactured to suit soil and
plant analysis conducted by clients in various areas. Once this market
began to develop, our knowledge of the nutritional requirements of
different crops in different growing areas throughout Australia
broadened, and especially in the rapidly expanding horticultural areas.
As Australian horticulture is growing at a rate of 25% per year,
expansion is, in a lot of cases, into very deficient and sandy soils in
arid semi-desert regions with high temperatures. Therefore traditional
horticultural practices are no longer applicable in these areas. We
needed products that would translocate quicker, bind to leaves under high
volumes of irrigation, be available through fertigation even in adverse
soil conditions, and bind to the soil so they would not leach.
The answer
was low molecular weight lignin with altered ionic charges. This gave us
a product with a high percentage of organic chelation that not only
improved the plant availability of nutrients but also had superior
binding properties. S.J.B. AG-NUTRI Pty. Ltd. now has a large range of
registered products that are independently manufactured and quality
controlled to S.J.B. AG-NUTRI specifications.
