RUSTICA PLUS by Campbells Fertilisers Australia
Slow-release NPKS compound fertiliser with Magnesium, Calcium and Micronutrients.
A dry spread application fertiliser that meets the complete nutritional requirements of vegetables, fruits, vines, flowers, turf and ornamentals. Rustica Plus has been widely used in Australian horticulture for over 40 years.
NUTRIENT FORMS:
Nitrogen is present both as nitrate and ammonium. The readily available nitrate-nitrogen gives an immediate growth response, while the more slowly available ammonium-nitrogen ensures a long-lasting effect.
Potassium is present as sulphate of potash only, which makes the product chloride-free.
Phosphorus is in a soluble form, allowing ready uptake by plant roots and is essential for the establishment and early development.
Secondary Nutrients and Micronutrients are present, with amounts tailored to plant production, with emphasis on calcium, sulphur, magnesium, zinc and boron.
ADVANTAGES:
The specific ratio of nutrients in Rustica Plus is formulated to meet the complete nutritional needs of a vast range of horticultural crops.
Rustica Plus has a low salt index and hence minimises the potential for fertiliser scorch. It is near neutral in its effect on soil pH, which helps maintain a productive soil environment.
Rustica Plus is a true compound fertiliser, not simply a mixture of different fertilisers pressed into a granular form (a granulated blend) or different fertilisers physically mixed together (a blended fertiliser). The consistent granule size range allows uniform application with no separation of nutrients.
APPLICATION FOR INDOOR PLANTS:
Apply compound pallets sparingly around the base of the plant and water as usual. The fertiliser will be released when watered. Once pallets completely dissolve, re-apply as needed. See the website for more directions before opening.
GENERAL APPLICATION:
Campbells Rustica Plus is ideal as a base or top dressing. It is a non-dusting, free-flowing product that can be applied as a band or broadcast or can be incorporated into the soil or growing medium prior to planting.
