Definitions

  • the present invention relates to certain free flowing plant nutrient compositions containing calcined clay granules having various plant nutrients attached thereto, a method for their preparation and a process for their use.
  • Growth media are generally mixtures of an organic material such as peat or tree bark with inorganic granular materials such as sand, perlite, or exfoliated mica. They have desirable air relations for commercial plant growing operations and are usually relatively free of insects and diseases compared to many natural soils. Additionally, they are easier to handle and ship due to lightness.
  • Micronutrients are iron, zinc, manganese, copper, boron, molybdenum and chlorine.
  • micronutrients to growth media
  • Another method of supplying certain of these micronutrients is to apply them as their metal chelates.
  • These chelates are in ready available form for plant uptake or foliar absorption. In general, they are used to cure an acute problem and are not effective for long term problems because leaching readily removes those chelates from the media. Thus, they must be applied repeatedly, making them expensive. Additionally, ionic micronutrients can not be supplied as chelates.
  • Plant nutrient compositions suitable for providing plant micronutrients to growth media should possess certain characteristics which include (1) essentially uniform chemical and physical properties;
  • An object of this invention is to provide plant nutrient compositions containing micronutrients which have essentially uniform chemical and physical properties, have a suitable means for micronutrient retention and release, have a low risk of providingmicronutrient imbalances, are compatible with growth media and can be easily incorporated into such media.
  • Another object of this invention is to provide slow release plant nutrient compositions.
  • Another object of this invention is to provide plant nutrient compositions containing micronutrients and the macronutrient sulphur.
  • the plant nutrient compositions of this invention include calcined clay granules as carriers having attached thereto micronutrients and the macro ⁇ nutrient sulphur.
  • the importance of sulphur is that it is used by plants in amounts comparable to phosphorus and should be present in amounts to provide a nitrogen: sulphur ratio of about 12:1 in order to metabolize protein.
  • Most high analysis fertilizers are nearly devoid of sulphur.
  • Calcined clay granules are utilized in the practice of this invention. It is to be understood herein that the term calcined clay means that it has been heated at elevated temperatures to effect bonding among individual particles. In general the clay should be calcined at a sufficiently high temperature i.e., 500o C. to 750o C. to insure dimensional stability wet or dry and should be capable of absorbing about 30 to 45% by weight of aqueous liquid and still maintain flowability of individual granules.
  • Such granules be largely composed of what is called three platelet or 2:1 layer silicate minerals.
  • the most widely distributed 2:1 clay is montmorillonite which is an essential component of what is called bentonite. Similar clays are attapulgite, sepiolite, chlorite and vermiculite. All of these clays to some degree have a permanent negative charge by isomorphous substitution of a lower valence cation for aluminum in the middle (octahedral) layer or aluminum for silicon in the outer Ctetrahedral) layer. The result of these quirks of nature is structural negativity not influenced by pH. For example, selected calcined clays have a permanent cation exchange capacity in the range of 15-25 milliequivalents per 100 grams.
  • the clay granules To be compatible with and allow even distribution throughout the commonly used growth media, which generally have a density of from about 0.3 to about 0.8 gm. cc and a particle size of from about 0.1 to 10 mm, the clay granules generally have a bulk density from about 0.4 to 0.8 grams per cc with a particle size from about 4 to about 50 mesh (U.S. standard seive).
  • micronutrients are attached to the calcined clay granules: iron, zinc, manganese, copper, molybdenum, boron and chlorine.
  • the macronutrient sulphur is also attached.
  • the micronutrients and macronutrient are present in a form suitable to nourish plants. Thus, they may be present in ionic form or combined as molecules, e.g., Fe +2 , Fe +3 , Zn +2 , Mn +2 , Cu +2 , H 2 BO 3 -1 , HBO 3 -2 , BO 3 -3 , MoO 4 -2 , Cl -1 , SO 4 -2 , FeSO 4 , ZnSO 4 , FeCl 2 and ZnCl 2 .
  • the plant nutrient compositions of this invention exhibit plant nutrient composition characteristics which include having essentially uniform physical and chemical properties, having a suitable means for nutrient retention and release, having a low risk of providing nutrient imbalances, being free flowing, having reduced dustiness, being compatible with growth media and being easily incorporated into growth media.
  • micronutrients and the macronutrient sulphur are present in the plant nutrient compositions of this invention in plant nutrient amounts, i.e., when such compositions are used in plant nourishing amounts, sufficient micronutrients and the macronutrient are present to nourish plant growth.
  • Nutrient amounts include, for example, in the case of iron an amount of from about 0.1 to about 5.0 weight percent, in the case of manganese an amount from about 0.05 to about 1.0 weight percent, in the case of zinc an amount from about 0.02 to about 2.0 weight percent, in the case of copper an amount from about 0.05 to about 0.5 weight percent, in the case of sulphur an amount from about 1.0 to about 5.0 weight percent, in the case of boron an amount from about 0.02 to about 0.03 weight percent, in the case of molybdenum an amount from about 0.0005 to about 0.0010 weight percent and in the case of chlorine an amount from about 0.1 to about 3.0 weight percent. All values are on an elemental basis, basedon the total weight of the plant nutrient composition.
  • compositions of this invention When the compositions of this invention contain cations they are attached to the negatively charged exchange sites until the charges are satisfied. Excess cations, anions and combined molecules, if present, are absorbed by physical forces and held on the internal and external surfaces of the granules. Usually, the ferrous ion, if present, oxidizes in part to ferric ion and this ion forms a coating on the granule which it is believed acts as a barrier to the free egress of the absorbed ions.
  • the bulk density of tile compositions of this invention is generally in the range from about 0.5 to about 1.2, preferably from about 0.8 to about 1.0 grams per cc and the particle size of the composition is in the range from about 4 to about 50 mesh U.S. standard seive.
  • compositions of the present invention are prepared by a method which comprises mixing with the calcined clay granules under ambient conditions a solution or suspension containing the micronutrients and the macronutrient, sulphur.
  • the solutions in highly concentrated form are sprayed on tumbling granules.
  • the micronutrients and sulphur in their water soluble salt form are dissolved in water to form the solution or suspension to be applied to the clay granules.
  • incompatibilities e.g., salting out, reaction, precipitation
  • more than one solution or suspension is employed.
  • a first solution containing ferrous chloride, boric acid, ammonium molybdate or other suitable soluble, iron, boron, molybdenum or chloride salts is applied by spraying to the calcined clay granules.
  • the concentration is from about 25% to about 35% on a dissolved solids basis.
  • a second solution containing manganese sulfate, zinc sulfate and copper sulfate or other suitable manganese, zinc, copper or sulphur salts is applied by spraying to the calcined clay granules.
  • a sequestering agent is contained in the solutions.
  • sequestering agents include citric acid, tartaric acid, ethylene diamine tetra acetic acid, ethylene diamine di (o-hydroxy phenyl acetic acid), etc. in sequestering amounts, usually from about 0.1% to about 5% by weight based on the total weight of the product composition of this invention.
  • the sequestering agents tend to accelerate the release of iron and other metallic ions.
  • the process of using the plant nutrient compositions of this invention comprises applying the compositions to the growth media in plant nourishing amounts , i . e . , an amount sufficient to nourish plant growth.
  • plant nourishing amounts i . e .
  • an amount sufficient to nourish plant growth is in the range of about 1 to 20 1b. per cubic yard of medium.
  • the compositions are conveniently applied by mixing the correct quantity with the media.
  • the resulting product weighed 1524 g. and flowed freely. It was extracted in 1:1 HCl and the elements converted to soluble form and analyzed by official methods of the Association of Agricultural Chemists. Chlorine was extracted in nitric acid and determined separately also by official methods.
  • the product was found to contain the following micronutrients. Percents are by weight on an elemental basis
  • the resulting product weighed 1000 lb. and flowed freely.
  • Example II The composition of Example II incorporated in a 1:1 peat-perlite at 5 1b. per cubic yard of mix was equilibrated at field capacity for 24 hours, then leached with 1/2-inch increments of water daily for 5 days.
  • the extract was composited and showed:
  • Marigolds were grown for 3 months in an untreated peat-perlite mix and a mix treated with 2.5 lb. of the composition of this invention per cubic yard. Analysis of the plants indicated the following concentrations of elements:
