た。Concentration of serum is performed for the purpose of facilitating the handling of a large amount of discharged natural rubber serum and increasing the content of its components when used as a fertilizer. . Concentrating the serum produces a precipitate of potassium sulfate, which has low solubility in the serum, and increases the viscosity, so it was not easy to handle it as a fertilizer in the liquid state. Does not cause precipitation of potassium sulfate,
When the natural rubber serum is diluted with water so that the viscosity becomes easy to handle, there is a problem that the serum has a low osmotic pressure and is prone to putrefaction. For this reason, utilization and development of natural rubber serum as a liquid fertilizer has not been conventionally performed.

造コストも高かった。However, the method of utilizing natural rubber serum as a solid fertilizer, which has been developed so far, requires more labor in spraying than the method of transporting by pipeline like a liquid fertilizer and spraying by a sprinkler,
It could not be used as is for hydroponics.
Further, the solid fertilizer usually has to undergo various steps of granulation, drying, and adjustment, and a large amount of heat is required for drying, so that the manufacturing cost is high.

の低下を起こすという問題があった。Further, since natural rubber serum is acidic, there is no problem when it is used at a low concentration, but if it is concentrated to enhance the effect as a fertilizer, plants may cause acid damage. Must be corrected. When urea is mixed as a nitrogen fertilizer in the production of solid fertilizer and it is attempted to correct the hydrogen ion concentration using this urea, ammonia is generated by heating for drying in the presence of sulfate radicals, and this is volatilized. Therefore, there is a problem that the nitrogen component is lowered.

It is preferable that the solid content concentration is pretreated by a method such as membrane separation, centrifugation, concentration or dilution to about 1 to 45% by weight, preferably about 15 to 30% by weight, and used in the method of the present invention. The reason for setting the solid content concentration of natural rubber serum to the above range is that the viscosity range is not so high that neutralization and various fertilizers can be dissolved and mixed efficiently, and the handling is easy. Also, it is possible to suppress the occurrence of precipitation of potassium sulfate having a low solubility in serum.

ある。The natural fertilizer composition of the liquid fertilizer composition of the present invention is acidic, so there is no problem when it is used at a low concentration, but acid damage of plants may occur when it is used at a high concentration. Conceivable. Neutralization is preferably carried out by adding urea, ammonia, ammonium phosphate or potassium phosphate. Urea or ammonia is mixed with natural rubber serum at room temperature. By using urea phosphate, ammonium phosphate such as diammonium phosphate, and potassium phosphate such as dipotassium phosphate hydroxide, the pH can be corrected without fear of ammonia volatilization. The range of hydrogen ion concentration of the neutralized liquid is
The pH is preferably 4-9, more preferably 5-8. Conventionally, natural rubber serum was heated and processed to be used as fertilizer, but when heated,
Urea decomposed in the presence of sulfate to generate ammonia. The generated ammonia volatilized as a gas, resulting in a decrease in the nitrogen content of the fertilizer composition. However, the present invention does not require heating because the final fertilizer form is liquefied, the decomposition of urea added as a neutralizing agent, the subsequent generation and volatilization of ammonia does not occur, and does not cause a decrease in nitrogen content. Therefore, there is an advantage that the use of urea is not restricted. The liquid fertilizer composition of the present invention preferably comprises a nitrogen fertilizer, a phosphate fertilizer, a potassium fertilizer, etc., using the natural rubber serum whose pH is corrected from such a weakly acidic to weakly alkaline region. is there.
