The results indicated that the soils were slightly acidic, with a low organic matter and total nitrogen content, as well as a low cation exchange capacity. The average carbon/nitrogen ratio of the soil was 10, a normal value with respect to the release of nitrogen. However, in correlating that ratio with the organic matter content, the higher the quantity of organic matter, the higher such ratio, and consequently the agricultural soils under study ...
