Abstract
A solid fertilizer composition which contains a growth nutrient for plants and which is soluble in an aqueous solution, characterized in that it comprises a solid carbon dioxide releasing substance and an inorganic acid for producing an effervescent effect when the composition is in contact with water.
Description
Solid fertilizer composition.
The present invention relates to a solid fertilizer composition which contains growth nutrients for plants.
More in particular, the present invention relates to a solid composition that is soluble in an aqueous solution.
It is known to produce fertilizer compositions in a powdery- form that are based on salts readily soluble in water.
A disadvantage of these powdery compositions is that they have a slow speed of dissolution and need stirring.
Another disadvantage is that during stirring, undissolved salts will move to the border on the bottom of a watering can, which makes it even harder to get dissolved. This will result in a non-homogeneous fertilisation of the plants.
Alternatively, it is known to produce fertilizer compositions in a liquid form that are based on salts readily soluble in water, which compositions are selected to give a suitable mixture of essential anions and cations. These liquids are often put in a bottle provided with a cap that can be used for dosage.
A disadvantage of these liquid compositions is that they are difficult to handle because the bottle becomes sticky and difficult to open due to the crystallization of salt between the bottle and the cap.
Another disadvantage of these liquid compositions is that it is very likely to get an incorrect dosage due to the presence of salt precipitates inside the cap.
Furthermore, fertilizers in the form of spikes, sticks or tablets for insertion in the potting medium have been developed.
A disadvantage is that these solid fertilizers are less efficient than liquid compositions with respect to nutrition.
Another disadvantage is that the distribution of nutrients in the soil is not very good and the nutrients do not reach all roots, which causes an additional and unnecessary constraint for the plant since the roots have to grow towards the spike, stick or tablet.
One more disadvantage is that the risk exists that too much fertilizer is dissolved in a small volume of the root environment, which results in salinisation and salt stress, which consequently reduces the plant growth performance.
Finally, fertilizer compositions in the form of tablets have been developed.
GB 2.134.506 describes such a fertilizer composition in the form of a tablet which is soluble in water, whereby the tablet contains growth nutrients . The tablet comprises a combination of a solid carbon dioxide-releasing substance
and a salt with an acid reaction for producing an effervescent effect when the composition is in contact with water.
In the first place, carbonates and bicarbonates are used as carbon dioxide releasing substance.
The other component in the effervescent mixture is a salt with acid reaction. More in particular, this salt can be a partial salt of an organic or preferably an inorganic polyvalent acid, like sulphuric acid and phosphoric acid.
A disadvantage of these tablets is that they are based on organic acids that do not contain nutrients, which results in less concentrated compositions.
The present invention aims to remedy one or more of the above-mentioned disadvantages .
To this end the present invention provides a fertilizer composition which contains a growth nutrient for plants and which is in the form of a solid material and soluble in an aqueous solution, whereby the composition comprises a solid carbon dioxide releasing substance and an inorganic acid for producing an effervescent effect when the composition is contacted by water.
An advantage of this fertilizer composition is that it is very reactive and that it can dissolve in water in a small amount of time.
Another advantage is that the fertilizer composition increases the amount of carbon dioxide of the soil atmosphere, and that plants assimilate the released carbon dioxide which has a beneficial effect on the growth of the plant.
Preferably, the inorganic acid of the fertilizer composition is a dry, crystalline, strong inorganic acid.
An advantage of these compositions is that they have a high concentration of nutrient substances.
According to a preferred embodiment of the invention, the fertilizer composition is produced in the form of effervescent tablets.
An advantage of these tablets is that they are easy to handle and that an accurate dosage is possible.
With the intention of better explaining the characteristics of the invention, hereafter, as an example without any limitative character, a preferred form of embodiment is described of a solid fertilizer composition according to the invention.
The solid fertilizer composition for plants according to the invention contains a growth nutrient for plants, which composition is soluble in water.
The fertilizer composition comprises at least a solid carbon dioxide releasing substance, readily soluble or
fairly readily soluble in water and which comprises a cation and an anion.
Preferably, the carbon dioxide releasing substance contains bicarbonates as they produce a very effective release of carbon dioxide relative to their weight but it is also possible to use carbonates or mixtures of carbonates and bicarbonates .
Alkali metals, with the exception of lithium, and ammonium form carbonates and bicarbonates that dissolve easily in water.
When a carbonate or bicarbonate of potassium or ammonium is used, the carbon dioxide releasing substance contributes to the nutritional value of the fertilizer composition at the same time. In particular, it is preferable to use potassium bicarbonate as a carbon dioxide releasing substance.
The fertilizer composition further comprises an inorganic acid, preferably a strong, inorganic acid whereby a strong inorganic acid offers the advantage that it dissolves easily in water whereby hydroxonium ions and negative ions are formed and virtually all the acid in the water solution will react with the water molecules to produce hydroxonium ions and negative ions .
An example of a strong acid that is particularly suitable for fertilizer compositions is phosphoric acid.
It is further preferable to provide the inorganic acid in a
dry, crystalline form as part of an adduct with a fertilizer salt.
This phosphoric acid can be provided in the dry form of urea phosphate (CO (NH2) 2.H3PO4) , which is an adduct of urea (CO (NH2) 2) and phosphoric acid (H3PO4) or it can be provided in the form of KH2PO4-H3PO4 which is an adduct of mono potassium phosphate (KH2PO4) and phosphoric acid (H3PO4) .
The above-mentioned substances providing the phosphoric acid, also contribute to the nutrient value of the composition as they contain nutritional elements for plants (N, P, K), which is in contrast with the organic acids currently used.
The fertilizer composition contains preferably a concentration of strong inorganic acid, that is sufficiently high for all carbon dioxide to be released from the carbon dioxide releasing substance.
It is further preferred that high amounts of carbon dioxide releasing substances are used so that the dissolution is as rapid as possible.
Preferably, the inorganic acid and the carbon dioxide releasing substance represent each 10 to 40% of the molecular weight of the composition.
Insofar as the other nutrient sources in the tablet are concerned they are the conventional N, P, K, magnesium (Mg), sulphur (S), calcium (Ca) sources such as, but not
limited to, ammonium sulphate, urea, ammonium nitrate, diammonium phosphate, mono-ammonium phosphate, mono- potassium phosphate, potassium nitrate, potassium sulphate, calcium nitrate, magnesium sulphate, magnesium nitrate.
Preferably, the substances delivering N, P, K, Mg, S and/or Ca represent 15 to 75% of the molecular weight of the fertilizer composition. This is without the nitrogen, phosphorus and/or potassium contribution from the inorganic acid and carbon dioxide releasing substance.
The fertilizer composition may also contain trace elements like boron (B) , copper (Cu) , iron (Fe) , manganese (Mn) , molybdenum (Mo) , zinc (Zn) . These trace elements can be provided in the composition in the form of carriers containing these elements, like for example salts, oxides, hydroxides, chelates and/or complexing agents. They represent up to 5% of the molecular weight of the fertilizer composition.
A suitable mixture of anions and cations is elected, taking into account, the concentrations of these ions that are obtained from the effervescent substances .
It is common practice in fertilizer compositions for potted plants to provide a ratio of 3:1:3 of NiP2C^K2O.
However, the NPK-ratio in the fertilizer composition can depend on the type of plant the composition is used for since different plants have different nutrition requirements .
If desired, substances which stabilize the fertilizer composition against moisture can be added to improve the storage stability of the preparation and to prevent a premature reaction between the effervescence producing substances, like for example starch, albumen and sodium sulphate.
When the fertilizer composition is provided in a tablet form, inactive ingredients or binders can be added to the composition in order to improve the strength of the tablet and to hold the tablet together. A wide variety of binders can be used, like for example lactose powder, dibasic calcium phosphate, sucrose, corn (maize) starch, microcrystalline cellulose or modified cellulose, like for example hydroxymethyl cellulose.
The fertilizer composition may also contain an ingredient that can act as a disintegrant , which hydrates readily in water and thereby improves the dispersion of the fertilizer composition in water. Some of the above-mentioned binders, like for example starch and cellulose, can also be used as a disintegrant.
When the fertilizer composition is provided in tablet form, it may be preferable to add a small amount of lubricants to the composition which helps the tablet, once pressed, to be more easily ejected from the die.
Commonly used lubricants are for example magnesium stearate, stearic acid (stearine) , hydrogenated oil and
sodium stearyl fumarate.
The tablets of the fertilizer composition may further be coated after being pressed. This coating should be stable and strong enough to survive the handling of the tablets. It is preferable to choose a coating that prevents the tablets from sticking together during the coating process. Moreover, the coating can also facilitate printing on tablets, if required. Tablet coatings can also be useful for extending the shelf-life of components that are sensitive to moisture or oxidation.
The fertilizer composition of the present invention is primarily intended to be used when watering potted plants but it can also be used for example when watering or supplying growth nutrients for example to flower beds and bushes .
The present invention is in no way limited to the embodiment described by way of an example, however, such a solid fertilizer composition according to the invention, can be realized in various forms without leaving the scope of the invention.
