System C

Agriculture Planter Design

AGRICULTURE PLANTER SYSTEM DESIGN

Planter system C is designed for agriculture planter systems with total depths greater than 14 inches and includes three layers; a drain layer, filter fabric, and intensive agriculture growth media layer. Each component provides favorable characteristics that influence plant growth through the supply of water and nutrients. The upper portion of System C is characterized by a high organic matter and a structural mineral mix to increase the porosity and water holding capacity, while maintaining long-term structural stability. Particle size distribution, organic matter and nutrient content have been adjusted to specifically meet the special requirements for farming and the production of highest quality produce. The separation fabric is put in place to mitigate the threat of migration of fine particles from the growing medium while still allowing root penetration. The bottom layer, or drainage layer, consists of a coarse aggregate to provide a high rate of water flow from the upper layers to the drainage system.

With any planter or container design, it is important that the volume, stability and health of the growth media do not change over time. By specifying and using the leading brand of certified green roof media, rooflite, the integrity of the system can remain intact for years to come. Regardless of shape, depth, or size, optimize your planter’s performance using these state of the art products.

For more information on the individual products in each of these layers, please see below:

rooflite intensive ag
A soilless blend containing premium organic components which mimic a fertile topsoil for farming or horticultural use.

This formulation of rooflite intensive has been optimized for farming. Particle size distribution, organic matter, and nutrient content have been adjusted to specifically meet the special requirements for farming and the production of highest quality produce. Several pilot farm projects using rooflite intensive ag have been very successful in producing delicious, fresh produce and having great yields.

Based on the USDA classification for types of soil rooflite intensive ag could be called a modified lightweight version of a sandy loam with high organic matter content and excellent supply of nutrients and beneficial microorganisms.

rooflite separation fabric
A thin, yet durable, fabric which has an important function as the top layer of the drainage – separating the coarser aggregate of the drainage from the base layer above. It is crucial that the rooflite separation fabric be root-permeable so that plants can use the total container volume for root growth. At the same time, rooflite separation fabric works as a filter, which keeps the finer particles contained in the media layers above from migrating into the drainage. rooflite separation fabric can easily be cut to fit any planter size and will not clog or degrade over time.

rooflite drain
A porous granular material, rooflite drain provides an excellent root environment with an ideal water/air distribution which allows for water retention and reliable drainage of excess water at the same time. Rooflite drain can be adjusted to any given area or depth.
