Description

FIELD OF THE INVENTION The present invention relates to a composition for fertilizing plant crops by-product comprising a manganese nutrient and optionally a mixture of clay minerals and / or vinasse and / or CMC.

In agricultural practice, many formulations are used to supplement individual nutrients. The technology of nutrient supply to crop plants has been particularly advanced in recent years.

Several chemical companies so called. has developed a product line (Peretrix, Fitohorm, Mikromix, etc.) to better adapt to farm needs.

Each composition may be chelated or complexed, partly in the form of a suspension (liquid solution, e.g. Voligop, Peretrix) suspension (e.g., Wuxal suspension), solid-granulated (e.g., Mikramid), crystalline (e.g. Fertilinz !, and its chemical composition.

No. 175,870. Hungarian Patent Lignosulfate, U.S. Patent No. 180,583; and a Hungarian patent describes lignocellulose-based metal chelates.

No. 178,991. Hungarian Patent Publication No. 181,455 to Oligo and Polyglucuronic Acid Metal Complexes; Maltobionic acid metal complexes, U.S. Pat. and U.S. Patent No. 4,123,125 discloses the metal chelate of a urea derivative.

Specifies a composition containing organic matter in U.S. Patent No. 174,081. Hungarian Patent Publication No. 175,338; and a iron-containing composition. Many known products are intended to meet plant needs, e.g. the Fitohorm product line for apples, wheat, corn and laying vegetables. (The Folisol and Mikromix product lines also provide several plant-specific formulations.) Zeafert is a formulation developed for maize. Many products are marketed with unique nutrient contents (eg Fitohorm, Voligop product lines) to enable companies to make individual nutritional deficiencies. Formulations have also been developed for certain special soils, e.g. iron deficient areas (Sequestern 330, Fertilon), manganese deficiency replacement (eg Manettra, Sequestern-Mn). Suitable for bulky areas is provided by No. 169,227. Composition according to Hungarian Patent Specification.

These formulations - liquid and solid plant nutrient mixtures - are available in a wide variety of formulations and compositions, but do not fully meet the needs of agricultural holdings for the following reasons:

the formulation of each formulation is limited by the manufacturing technology and brand name, some formulations have high taper costs, the simultaneous application of the micro and macro elements is either not possible or requires the development of a separate blending technology.

It is an object of the present invention to provide for the replacement of manganese, optionally with other micro-nutrients, soil and crop rotations, while simultaneously replacing the macro- and meso-nutrients.

It is another object of the present invention to replace the trace elements of manganese, optionally other, such as Fe, Mn, Zn and Cu, by applying a liquid fertilizer in the most modern form so as to improve the stability and handling of the liquid fertilizer.

It is a further object of the present invention to provide a composition which is fully adapted to the needs of the farm and enables the application of manganese, optionally other trace elements, in a single operation with the liquid fertilizers.

It has been recognized in our work that the above object is achieved by using a composition for fertilizing crop plants which comprises a combination of a manganese by-product obtained during manufacture and, optionally, vinasse and other macromolecular material and mineral.

The present invention thus provides a composition for fertilizing crop plants with the use of a by-product which comprises 0.01-0.9% by weight, preferably 0.02-0.05% by weight, of manganese acetate in a ratio of 1:10 to 10: 1 based on the solid weight of the fertilizer. and carboxymethylcellulose (CMC) having a defined pH by-product containing sulfate and sulfate and optionally containing 1.3-1.7 methyl groups per unit mineral and / or vinasse and / or glucose anhydride, preferably 12-30% by weight. 0.01-0.3: 0.01-10: 0.1-1. The density of the vinasse is 1.2-1.4 t / m ³ , preferably 1.39 t / m ³ . The pH of the manganese byproduct is between 4 and 6.5. The manganese-containing by-product and / or optionally, the trace elements are added according to the needs of the plant according to soil and plant test data. The stability of the liquid fertilizer can optionally be improved with charcoal powder below 100 microns. The manganese-containing by-product may optionally be supplemented with other biologically active substances during the production of the nitrogen solution.

It is an essential feature of the present invention that the combination of a manganese by-product obtained during manufacture and optionally vinasse and other macromolecular substances and clay minerals increases the stability or efficiency of the liquid fertilizer.

It is a further discovery of the invention that the manganese by-product, optionally supplemented with vinasse and other macromolecular substances and clays, increases the utilization of manganese, optionally other micro and meso elements, after application to the soil.

It is a further object of the present invention that between the manganese acetate and sulfate by-products (1: 10 to 10: 1) and optionally vinasse of appropriate density or other macromolecular material and clay mineral, the stability of the liquid fertilizer and there is a synergistic effect on the utilization of other micronutrients.

It is further recognized that the density of the vinasse and the degree of substitution of the CMC used are critical to the structure, stability and viscosity of the resulting suspension.

The composition according to the invention is prepared by adding the manganese acetate and sulfate (1: 10-10: 1) by-product to the nitrogen solution according to the needs of the farm, or with a specific density of vinasse and optionally with a degree of substitution CMC and / or mixed with clay and added to the liquid fertilizer.

By-products containing manganese acetate and sulfate in a ratio of 1:10 to 10: 1 are used in the organic chemical industry for esterification and purification. resulting from separation operations.

The following are non-limiting examples of the composition and preparation of the invention. Some examples of comparative applications are also presented. (% In the example would break g%.)

After the slurry had warmed up, 3.5 t of white crystalline potassium salt containing 60% K2O was added followed by 0.6 t of urea. After 10 minutes of vigorous stirring, 2.1 t of a stabilizer containing 0.15% by weight of manganese by-product and 0.5% by weight of CMC with a degree of substitution of 0.7 is added. This gives essentially 10 m ³ NPK slurry fertilizer 90: 180: 270.

Comparative Application Examples

Example 5

For potato plants grown on brown forest soil (Ka * = 48, humus content = 2.1%), the fertilizer of Example 1 was applied in the autumn at 800 l / ha. The yield increased by 4.5% (13.5 q / ha) compared to the control ** plot.

Example 6

The tubers were treated with the liquid fertilizer of Example 1 at planting on sandy loam brown forest soil (Ka = 40, humus content = 2.05%, P2O5mg / 100g soil = 10, K2O mg / 100g soil = 16). The liquid fertilizer was sprayed onto the tuber at a volume of 30 1 / t. The rate of tuber dressing improved and yield was 5 t% (20 q / ha) higher. Starch content and vitamin C content increased significantly in the treated area.

Example 7

Example 11

On chernozem type soil (Ka = 46, CaCoa content = 2%, humus content = 3%, AL '' soluble phosphorus and potassium medium), the liquid fertilizer of Example 2 was applied to 1000 l / ha of maize prior to seedbed preparation. The yield was 8 t / ha, δ t% higher than the control plot.

'Ka = Gold binding' In the examples, the control plot is the soil treated with fertilizer not containing the additive of the invention.

"'AL = aluminum lactate

Example 8

800 l / ha of liquid fertilizer of Example 2 was applied to the Mn-deficient grassland in the fall. The yield (3 t / ha hay) did not increase significantly, but the starch value and Mn content of the hay was higher in the treated area.

Example 9

For head fertilization of wheat grown on meadow chernozem soil (Ka = 50, CaCO3 content = 0.5%, humus content = = 3.5%, A1 soluble phosphorus medium, AL soluble potassium good - medium), 3. The fertilizer-containing liquid according to Example 1 is dispensed. The yield increased by 3% (1.5 t / ha), and the condition of the herb was improved by 1 unit during the vegetation by bonitization (scale 5).

Example 10

Field crops grown on field soil (Ka = 43, CaCOa content = 2%, humus content = 2.1%, AL soluble phosphorus = 10 mg / 100 g soil, AL soluble potassium = 18 mg / 100 g soil) in September 800 l / ha of liquid fertilizer according to Example 3 were sprayed and 80 kg / ha of nitrogen head fertilizer was added in the form of a nitrogen solution (28% by weight N and 0.5% by weight Mn). The stock was credited (scale 5). The treated area developed more vigorously during the vegetation (1 unit better than the control) and the yield was 0.5 t / ha higher. (Both powdery mildew and fusarium infection decreased by 1 unit - bonitization - which contributed to the increase in yield.)

Spring barley (malting barley) cultivation (Ka = 43, CaCO3 content = 0.5%, humus content = 1.8%, AL soluble phosphorus and potassium medium) was applied at 800 l / ha in the fertilizer of Example 4. Liquid fertilizer improved the quality of the crop by increasing the opening content of the kernel by about 10 t% and by approx. The protein content decreased by 15% on average in several field experiments. (The fracture surface of the grains and the weight of a thousand grains changed significantly in terms of the qualification of malting barley.)

Example 12

The average 3-year results of small plot trials with potato signaling (6 is20 repetitions) significantly demonstrated that 800 l / ha liquid fertilizer fertilizer to soil and tubers of Example 4 promoted stolon formation and improved tuber binding (by bonitization). It also had a positive effect on tuber size distribution and starch content. The yield increased by 1.5-3 t / ha.
