Definitions

  • Foliar feeds are conventionally applied as solutions of dissolved salts to the plant leaves. Recent research has demonstrated that, initially, the feed moves mainly through the stomata, while later on, penetration across the cuticle is the primary pathway.
  • the foliar feed solution contains both positively charged cations and negatively charged anions, which enter the plant through stomata, found mostly on the undersides of the leaves.
  • the stomatal pores are the main route for the entry of carbon dioxide (CO 2 ) into the plant and the exit of water vapour from the plant. Once the plant surface has been hydrated, the main entry of dissolved salts into the leaf is via the cuticle and its polar pores; the smaller molecules entering faster than the larger ones.
  • a problem with the conventional application of foliar feeds is that the initial uptake of the dissolved salts into the plant is dependent on the regulation of the opening of the stomatal pores. At least two mechanisms trigger the opening or closing of stomatal pores. Firstly, in most plants the stomata are closed at night and the CO 2 is depleted during the dark phase of photosynthesis. At dawn, light triggers the stomata to open and resume CO 2 uptake. Secondly, when the amount of water entering the leaf via the roots is less than the amount of water exiting the leaf in the form of water vapour, such as would occur in hot weather, the stomatal pores close in order to protect the leaf from further dehydration.
  • Figure 3 shows the comparative growth of tomato plants treated with the nutrient feed solution
  • the nutrient feed solution is produced by way of a cation exchange process, preferably involving a cation exchanger.
  • a cation exchanger there are many different types that could be used, including a cation exchange resin or a fibrous ion exchange medium.
  • a cation exchange resin is particularly preferred.
  • the resin may be in the form of a gel resin, a macroporous resin or a fabric type resin. It will, however be appreciated that the cation exchanger also may comprise a combination of cation and anion exchange resins with cation and anion fibrous ion exchange mediums that incorporate cathodes and/or anodes, and which separate the cations and anions in a process of electro- deionisation.

Abstract

L'invention concerne un procédé permettant de fournir un apport de nutriants à une plante, une solution d'apport de nutriants contenant ceux-ci, et un processus et une composition permettant d'obtenir ladite solution. Notamment, cette invention a pour objet une solution d'apport de nutriants, spécifiquement, une solution acide inorganique diluée à appliquer sur les parties aériennes d'une plante, ladite solution contenant des nutriants qui ont des molécules suffisamment petites pour traverser rapidement une cuticule de plante.
