The Relationship between Acid Fragrance Spirit and Humidity and Soil Quality

Further, the relationship between soil quality, humidity and organic acids (including citric acid, malic acid, acetic acid, fatty acid, chlorogenic acid) and inorganic acids (phosphoric acid) in coffee beans was discussed. Dr. Guyot of the International Centre for Agricultural Development Research in France and chemist Joseph E. Joseph A. Rivera Rivera concluded that:

Volcanic rock producing areas are easy to breed a good body and a good taste of coffee. The coffee tester also found that coffee from volcanic rock soil has the most balanced acid, aroma, sweet, alcohol and bitter flavors, and also the most diverse. The study found that this is because volcanic rocks contain high concentrations of sulfur and sulfide, which happen to be essential elements before some aromatic spirits are synthesized, so coffee grown in volcanic areas usually has a stronger aroma. In addition, the soil is rich in potassium, which contributes to the body of the coffee, and also increases the weight of the beans and the thickness of the branches. Interestingly, Vivitenango, Coban (located in the north) and New Oriental three of Guatemala's eight major producing areas are not volcanic soil, and the coffee flavor is obviously different from the other five volcanic producing areas. The overall flavor of Vivetnam fruit (strong acid), Coban (heavy fruit flavor) and New Oriental (prominent chocolate flavor) is unbalanced, but it is very beautiful, which may be caused by less sulfur and potassium elements in the soil of these three areas.

When breeding coffee trees, you can choose some weakly acidic soil, but basically coffee trees do not have very high requirements for soil, so you can raise them with garden soil mixed with other soil.

If you want to keep the soil weak acid, you can pour a little rice washing water when you usually maintain it.

Return soil and build platform 15 - 30 days before planting. The thickness of the first return soil is 0. 20 meters, then add 1500 kilograms of farm manure +100 kilograms of phosphorus fertilizer per mu, evenly stir the base fertilizer. After the second soil return, the groove will be filled up and the level ladder will be carried out. The table width is required to be 1. 20 meters, table inclined 2 - 3 degrees. After finishing the table, lime powder will be evenly spread on the table, the purpose is to adjust the soil PH value, enhance the soil microbial activity, and improve the effectiveness of soil mineral nutrients.
