Increased fertiliser efficiency, together with effective water drainage and optimal soil aeration, are essential for increased productivity in the horticultural sector.
Grolite® from Pratley: A Unique Solution
Grolite® from Pratley is a unique, naturally occurring processed mineral used extensively as a horticultural growing medium.
Pratley’s Innovative Process
Pratley Marketing Director Eldon Kruger
Pratley actively processes a volcanic mineral called Perlite sourced from a unique deposit in South Africa. The ore is processed using proprietary technology to produce Grolite® for the horticultural and hydroponic industry.
Benefits of Grolite® Horticultural Perlite
“Grolite® allows for improved fertiliser efficiency, which boosts plant health and growth. It also promotes water drainage, while retaining the required moisture, leading to healthier plants and increased crop yields. In a water-scarce country like South Africa, this is vital to horticulturists,” Pratley Marketing Director Eldon Kruger comments.
Micropores and Capillary Action
Tiny micropores on the surface of the Grolite® particles assist in capturing nutrients and water molecules. The capillary action occurring in the voids between the particles ensures uniform distribution of water and nutrients, which results in consistent and improved crop yields.
Optimal Soil Aeration
Grolite® also maintains optimal soil aeration, a critical factor in normal plant growth. This is because the supply of oxygen to roots in adequate quantities is essential for healthy plant growth.
Sterile and Durable
Grolite® is processed at temperatures in excess of 950°C, resulting in a sterile product that is completely free of weeds and pathogenic microbes. Unlike other ordinary horticultural Perlites, the unusually strong surface structure of Grolite® means it does not deteriorate during transportation or when being mixed.
Cost-Effectiveness and Reusability
This unique feature means hydroponic farmers, for example, can reuse the product for more than one season, increasing its cost-effectiveness. “It’s a feature which is quite specific to Grolite®, as the Perlite raw material is from an older deposit which is unlike perlite deposits found in other parts of the world,” explains Eldon.
Nationwide Availability and Expert Support
Grolite® is available nationwide in various grade sizes to cater for specific blends. “Pratley experts are always on hand to discuss specific customer requirements, or to respond to any queries,” Eldon highlights.
