Description
【０００１】
【産業上の利用分野】
本発明は、石灰混合肥料、すなわち石灰を主剤とし、これに水酸化マグネシウムおよびカキガラを配合し、場合によりさらに腐植酸を添加してなる肥料に関する。本発明はまた、上記諸成分を一粒に造粒した、飛散しにくく取り扱いやすい形態の混合石灰肥料に関する。
【０００２】
【従来の技術】
作物、たとえば種々の野菜の作付け前に、土壌のｐＨを矯正することと石灰を補給することを目的として「石灰質肥料」が使用されている。その材料は、生石灰、消石灰、炭酸カルシウム、貝化石などであり、この種の肥料は、単独で施肥されることが多い。
【０００３】
土壌改良剤としては、水酸化マグネシウムも用いられている。これは肥料取締法にいう「苦土質肥料」に該当し、苦土成分がもっとも高いものである。肥料といっても、実際の施用は苦土補給のみを目的とするもので、苦土の欠乏が生じやすい土壌に用いるだけである。
【０００４】
腐植酸は、土壌改良資材として、有機物の補給、ＣＥＣ、保水性の増大および土壌微生物の活性化など、土壌物理・化学・生物性の改善を目的に、しばしば施用されている。このほか、微量要素の補給には、ホウ酸、マンガン等の塩を調合した微量要素肥料が施用されている。
【０００５】
上記の石灰質肥料または苦土質肥料に腐植酸を添加したものが提案され、市販されている。これらは通常、単独で土壌改良用ととして施用されている。（参照：特開昭５０−３８５０、特開昭５１−２７５７５、特許第３０８７９４４号）
【０００６】
前述の肥料および土壌改良資材は、その特性と土壌の要求ないし条件が合致すれば、単独での施用で、十分にその効果を発揮することができる。しかし、近年の農業従事者の減少と、高齢化の傾向により、畑の管理が不十分になりがちであるという農業環境の中、Ｎ・Ｐ・Ｋを主体とした各種肥料の多量施用、土壌中の塩類過多、有機物・苦土・微量要素の不足、酸性化など、土壌が当面する問題はさまざまであり、より適切な資材の使用が望まれている。
【０００７】
しかし、現実には、望ましい形での施肥は、必ずしも行なわれていない。たとえば石灰質肥料は、有機物と同時に施用すると作物に対しとりわけ効果があるとされているが、昨今の畜産や酪農の停滞による慢性的な農業用有機物の不足と、その取り扱いが嫌われやすいことから、石灰質肥料のみの施用に頼っているのが現状である。水酸化マグネシウムはマグネシウムの補給源であり、緩効的に土壌に作用し、その効果は長期間にわたり持続性がある。酸性の強い土壌では、石灰質肥料と併用することが望ましいが、併用は面倒である。
【０００８】
腐植酸だけの施用は、上記した諸効果すなわち有機物の補給、ＣＥＣ、保水性の増大、土壌微生物の活性化などが期待できるが、単独では化学成分（Ｎ，Ｐ，Ｋ，Ｃａ，Ｍｇ）の補給が行なわれず、十分な土壌改良には至らない。そこで、石灰質肥料、または苦土質肥料に腐植酸を混合しものが考案され、すでに市販されているが、それだけでの施用では、ホウ素、マンガン等の微量要素が不足し、十分な土壌改良には繋がらない。微量要素を補給するための微量要素肥料は、施用量が少量であるため、畑全体に均一に施肥することが難しく、土壌中で成分の偏在を生じがちであるという問題を含んでいる。
【０００９】
各種の肥料や土壌改良剤の同時施用はまた、各資材の計量や配合などの作業に伴う頻雑さが生じ、資材によっては粒子が微細で飛散しやすいものもあり、施用時に問題がある。
【００１０】
【発明が解決しようとする課題】
本発明の一般的な目的は、石灰石、ドロマイト、カキガラ、さらには腐植酸のもつ特性を生かして、それらを適切なバランスをもって組み合わせ、複雑な土壌条件にも合致できるように、石灰成分、苦土成分、微量要素、さらに腐植酸成分の割合を調整したものであって、一時に施用することができる混合石灰肥料を提供することにある。本発明の特別な目的は、この混合石灰肥料を一粒にした造粒物であって、飛散しにくく取り扱いが容易な混合石灰肥料造粒物を提供することにある。
【００１１】
【課題を解決するための手段】
本発明の一般的な目的を達成する混合石灰肥料の、第一の形態は、下記の諸成分を配合してなる混合石灰肥料である（％は重量）。
１）ドロマイトまたは石灰石：
ドロマイトの場合は２０〜４０％、石灰石の場合は３０〜５０％、
２）水酸化マグネシウム：１０〜４０％、および
３）カキガラ：１０〜６０％。
【００１２】
第二の形態は、上記に腐植酸成分を加えたものであって、下記の諸成分を配合してなる混合石灰肥料である（％は重量）。
１）ドロマイトまたは石灰石：
ドロマイトの場合は２０〜４０％、石灰石の場合は３０〜５０％、
２）水酸化マグネシウム：１０〜４０％、
３）カキガラ：１０〜４０％、および
４）腐植酸：５〜４５％。
【００１３】
【発明の実施形態】
第一および第二の形態において、各成分の配合割合を上記のように定めた理由は、つぎのとおりである。
【００１４】
ドロマイトまたは石灰石：
ドロマイトの場合は２０〜４０％、石灰石の場合は３０〜５０％
石灰は、酸性土壌の矯正に有効であり、酸性土壌の多い日本の畑地には好適な材料である。石灰肥料に水酸化マグネシウム成分を添加することにより、効果が長期にわたり、一度の施用でも栽培期間中安定して石灰成分や苦土成分を補給することができる。しかし、水酸化マグネシウムそれ自体は、肥料の原料としては高価なものである。そこで、炭酸カルシウムとともに炭酸マグネシウムを含有する鉱物である、ドロマイトの使用が推奨される。ドロマイトは、栃木県をはじめ国内で産出する資源であり、水酸化マグネシウムに比較すれば安価に入手できるから、ドロマイトを混合して、有効成分中の苦土分を補充することは、コスト面でも有利である。石灰石を使用する場合は３０〜５０％の範囲で、ドロマイトを使用する場合は、これが苦土成分の補給源をも兼ねていることから、２０〜４０％の範囲で、それぞれ配合する。
【００１５】
水酸化マグネシウム：１０〜４０％
ニガリに石灰乳を添加して沈殿させたものや、海水から製造した水酸化マグネシウムを使用する。苦土成分の補給源としてドロマイトを使用する場合、それに応じて、水酸化マグネシウムの配合量を減らすことができる。その場合の量は、１０〜３０％の範囲から選ぶことが適当である。
【００１６】
カキガラ：１０〜４０％
海産物であるカキガラには、海水中から取り込んだ臭素、マンガン、亜鉛等の微量成分が含まれ、しかもカキガラは産業廃棄物であって安価であるから、積極的に利用することが好ましい。微量要素源としては、ホウ酸塩やマンガン塩を使用すればよいが、これらは高価であるから、わざわざ市販品を使うのは不利であり、カキガラに求めることが賢明である。いうまでもなくカキガラの主成分は炭酸カルシウムであって、石灰成分の源であるが、本発明ではカキガラを、むしろ微量要素の補給源として利用する。カキガラはまた、この混合肥料を、畑に均一に撒布することを助ける。上記の効果を確実に得るためには、少なくとも１０％の配合を必要とする。一方、他の成分とのバランスから、最大４０％を上限とする。
【００１７】
腐植酸：５〜４５％
腐植酸は、石灰などのアルカリ性資材と同時に施肥すると、土壌中で溶け出して、カルシウムやマグネシウムを土中に浸透させるはたらきをする。また、土壌中の鉄やアルミナによるリン酸の固定をやわらげ、熟畑化を促進し、保肥効果を高め、土壌の急激な酸性化や塩類濃度障害を防ぐ、緩衝能を与える。これらの作用は、腐植酸のＣＥＣ（陽イオン交換容量）が大きいほど強いから、ＣＥＣが２００ｍｅｑ以上のものを使用することが好ましい。腐植酸は、石灰類と混合施肥することにより、相乗的な効果となって得られる。こうした効果を確保するには、５％以上の存在が必要であるが、他の成分とのバランスを考えると、配合量の上限は４５％である。通常好適な範囲は、１０〜３０％である。
【００１８】
本発明の混合石灰肥料において、飛散が避けられ、取り扱いが容易である造粒物は、上記した各原料を適切な割合で配合し、粉砕して混合し、圧片成形法または転動造粒法により成形し、粒径を０．５〜１０ｍｍの範囲に揃えてなるものである。
【００１９】
造粒物の中でも製造が容易で、かつ使用にも好都合なものは、バインダーを使用して、転勤造粒法により成形したものである。バインダーとしては、下記の材料から選択したものの１種または２種以上が好適である：
イースト菌発酵廃液、アミノ酸発酵廃液、パルプ廃液、カラメル製造廃液、乳酸発酵廃液、アルコール発酵廃液、および化工でんぷんの水溶液もしくは水分散液
【００２０】
これらのバインダーは、糖、各種アミノ酸（グルタミン酸、ロイシン、チミン等）、リグニン系有機物などを含有するので、施肥後、土壌微生物の繁殖に寄与し、有機物の分解を早め、さらに熟畑化を促進させるメリットがある。適切な添加量は、バインダーのもつ粘結力や、水溶液の場合は濃度などの因子によって異なるが、通常、原料配合物に対して重量で５〜２０％の範囲にある。

【発明の効果】
本発明の混合石灰肥料は、石灰成分、苦土成分および微量要素を、対象土壌の特性に合わせて組み合わせた組成を有し、態様によってはさらに腐植酸成分をも含有するから、日本のどの地域の土壌に使用しても、十分な改良効果を上げることができる。原料にはとりたてて高価なものはなく、とくに苦土成分の補給源としてドロマイトを使用することにより、水酸化マグネシウムの使用量を少なくした態様は、コスト面できわめて有利である。市販の水酸化マグネシウムの価格と比較すると、ドロマイトの粉砕品は、一桁低い価格で入手することができるからである。各原料を配合し、粉砕して一粒に造粒したものは、施肥に当たって飛散することがなく、取り扱いが容易である。[0001]
[Industrial applications]
The present invention relates to a lime-mixed fertilizer, that is, a fertilizer comprising lime as a main ingredient, magnesium hydroxide and oysters, and optionally further adding humic acid. The present invention also relates to a mixed lime fertilizer in which the above-mentioned components are granulated into a single grain, in a form that is difficult to fly and easy to handle.
[0002]
[Prior art]
Prior to planting crops, such as various vegetables, "calcinous fertilizers" are used to correct soil pH and replenish lime. Its material is quicklime, slaked lime, calcium carbonate, shell fossils and the like, and this type of fertilizer is often applied alone.
[0003]
Magnesium hydroxide is also used as a soil conditioner. This corresponds to the "mafic fertilizer" referred to in the Fertilizer Control Law, and has the highest magnesia content. Even though fertilizers are used, the actual application is only for the purpose of replenishing the mafic soil, and is only used for soils that are liable to be depleted in mafic soil.
[0004]
Humic acid is often applied as a soil improving material for the purpose of improving soil physics, chemistry, and biological properties, such as replenishment of organic matter, CEC, enhancement of water retention, and activation of soil microorganisms. In addition, trace element fertilizers prepared by mixing salts such as boric acid and manganese are applied for replenishment of trace elements.
[0005]
The above-mentioned calcareous or fertile fertilizers added with humic acid have been proposed and are commercially available. These are usually applied alone for soil improvement. (Reference: Japanese Patent Application Laid-Open Nos. 50-3850, 51-27575, and 3087944)
[0006]
The above-mentioned fertilizer and soil improvement material can sufficiently exert their effects by application alone if the characteristics and the requirements or conditions of the soil match. However, in the agricultural environment where the management of fields tends to be inadequate due to the decrease in the number of agricultural workers and the tendency of aging in recent years, the application of a large amount of various N, P, and K fertilizers and soil There are a variety of problems with the soil at hand, such as excess salt in the soil, lack of organic matter, hard soil, and trace elements, and acidification, and the use of more appropriate materials is desired.
[0007]
However, in practice, fertilization in a desirable manner is not always performed. For example, calcareous fertilizers are said to be particularly effective for crops when applied simultaneously with organic matter.However, due to the recent shortage of agricultural organic matter due to the recent stagnation of livestock and dairy farming, and the tendency to dislike their handling, At present, they rely only on calcareous fertilizers. Magnesium hydroxide is a source of magnesium and acts slowly on the soil, the effect of which is long lasting. In strongly acidic soils, it is desirable to use it together with calcareous fertilizers, but the use is troublesome.
[0008]
Application of only humic acid can be expected to have the above-mentioned effects, ie, replenishment of organic substances, increase of CEC, increase of water retention, activation of soil microorganisms, etc., but the chemical components (N, P, K, Ca, Mg) alone can be expected. There is no replenishment and no sufficient soil improvement. Therefore, a mixture of humic acid and calcareous fertilizer or mafic fertilizer has been devised, and it is already on the market.However, application by itself is insufficient for trace elements such as boron and manganese. I can not connect it. The trace element fertilizer for replenishing the trace elements has a problem that it is difficult to apply the fertilizer uniformly to the whole field because the application amount is small, and tends to cause uneven distribution of components in the soil.
[0009]
Simultaneous application of various fertilizers and soil conditioners also involves frequent operations such as weighing and blending of each material, and some materials are fine and easily scattered, which is problematic in application.
[0010]
[Problems to be solved by the invention]
The general object of the present invention is to make use of the properties of limestone, dolomite, oysters, and humic acid, to combine them in an appropriate balance, and to make them compatible with complex soil conditions, It is an object of the present invention to provide a mixed lime fertilizer in which the proportions of components, trace elements, and humic acid components are adjusted and can be applied at one time. A special object of the present invention is to provide a granulated product in which the mixed lime fertilizer is made into one granule, which is hard to be scattered and is easy to handle.
[0011]
[Means for Solving the Problems]
A first form of the mixed lime fertilizer which achieves the general object of the present invention is a mixed lime fertilizer comprising the following components (% is weight).
1) Dolomite or limestone:
20-40% for dolomite, 30-50% for limestone,
2) Magnesium hydroxide: 10-40%, and 3) Oysters: 10-60%.
[0012]
The second form is a mixed lime fertilizer to which the above-mentioned humic acid component has been added, and which comprises the following various components (% is weight).
1) Dolomite or limestone:
20-40% for dolomite, 30-50% for limestone,
2) magnesium hydroxide: 10 to 40%,
3) Oysters: 10-40%, and 4) Humic acids: 5-45%.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
In the first and second embodiments, the reason why the mixing ratio of each component is determined as described above is as follows.
[0014]
Dolomite or limestone:
20-40% for dolomite, 30-50% for limestone
Lime is effective in correcting acidic soil, and is a suitable material for Japanese farmland with a lot of acidic soil. By adding the magnesium hydroxide component to the lime fertilizer, the effect is long-term, and even with a single application, the lime component and the formic component can be replenished stably during the cultivation period. However, magnesium hydroxide itself is expensive as a raw material for fertilizers. Therefore, the use of dolomite, a mineral containing magnesium carbonate together with calcium carbonate, is recommended. Dolomite is a resource that is produced domestically, including in Tochigi Prefecture, and can be obtained at a lower cost than magnesium hydroxide.Therefore, it is costly to mix dolomite and replenish the formic acid in the active ingredient. It is advantageous. When limestone is used, it is blended in the range of 30 to 50%, and when dolomite is used, it is blended in the range of 20 to 40% because it also serves as a supply source of the formic component.
[0015]
Magnesium hydroxide: 10-40%
Use lime milk added to bittern and precipitated, or magnesium hydroxide produced from seawater. When dolomite is used as a replenishment source for the formic component, the amount of magnesium hydroxide can be reduced accordingly. The amount in that case is suitably selected from the range of 10 to 30%.
[0016]
Oysters: 10-40%
Oysters, which are marine products, contain trace components such as bromine, manganese, and zinc taken from seawater, and because oysters are industrial waste and inexpensive, it is preferable to actively use them. As a trace element source, a borate or a manganese salt may be used, but since these are expensive, it is disadvantageous to use a commercially available product, and it is wise to ask for a oyster. Needless to say, the main component of the oyster is calcium carbonate, which is a source of the lime component. However, in the present invention, the oyster is used as a source for supplying trace elements. Oysters also help spread this mixed fertilizer evenly over the field. To ensure the above effects, at least 10% of the compound is required. On the other hand, from the balance with other components, the upper limit is 40% at the maximum.
[0017]
Humic acid: 5-45%
Humic acid, when fertilized at the same time as alkaline materials such as lime, melts out in the soil and acts to infiltrate calcium and magnesium into the soil. It also softens the fixation of phosphoric acid by iron and alumina in the soil, promotes ripening, enhances the fertilizing effect, and provides a buffering capacity that prevents rapid acidification of the soil and impairment of salt concentration. Since these effects are stronger as the CEC (cation exchange capacity) of the humic acid is larger, it is preferable to use one having a CEC of 200 meq or more. Humic acid can be obtained as a synergistic effect by mixing and fertilizing with limes. To ensure such effects, the presence of 5% or more is necessary, but considering the balance with other components, the upper limit of the blending amount is 45%. A generally preferred range is 10-30%.
[0018]
In the mixed lime fertilizer of the present invention, the granulated material which can be prevented from being scattered and which is easy to handle is prepared by blending the above-mentioned raw materials in an appropriate ratio, pulverizing and mixing, and using a pressure molding method or rolling granulation. It is formed by a method and the particle size is adjusted to a range of 0.5 to 10 mm.
[0019]
Among the granules, those which are easy to manufacture and convenient to use are those formed by a transfer granulation method using a binder. Suitable binders are one or more selected from the following materials:
Yeast fermentation waste liquid, amino acid fermentation waste liquid, pulp waste liquid, caramel production waste liquid, lactic acid fermentation waste liquid, alcohol fermentation waste liquid, and aqueous or aqueous dispersion of chemical starch
Since these binders contain sugars, various amino acids (glutamic acid, leucine, thymine, etc.), lignin-based organic substances, etc., they contribute to the propagation of soil microorganisms after fertilization, accelerate the decomposition of organic substances, and promote ripening fields. There is a merit to make. The appropriate amount of addition varies depending on factors such as the binding power of the binder and the concentration in the case of an aqueous solution, but is usually in the range of 5 to 20% by weight based on the raw material formulation.
