Do not adversely affect pH of soil.
Microbial activity and vitality of soil is enhanced leading to sustainable enhanced production.
Naturally Slow Release (sustained release) with roughly 18%-20% (tested by CA Labs and measured after dissolving in citric acid solution) of nutrients being immediately available to the plant, the balance being released by microbial activity in the soil over an extended period.
Applied every 4-6 months in good soil, which amounts to labour reduction, cost savings, and less management effort.
Granular in structure which allows fertiliser to be trapped between soil particles where nutrients are released over an extended period, making it a beneficial fertilizer (even in sandy soil) as nutrients are not lost through leaching.
