Abstract


Evaluation of soil fertility status on agricultural is to know the fertility of soil chemically through soil analysis or soil test. This is done to obtain estimates data of land characteristics based on parameters observed and tested for various alternative uses based on specific objectives. Parameters used to assess soil fertility status are Cation Exchange Capacity (CEC); Bases Saturation (BS); Organic Carbon; Total P and K levels. Evaluation of soil fertility status is needed as an effort to know the potential and direction of the management of production land on the cultivation of agricultural crops, and to know the factor of fertility that limits on the land. Based on the above description, it is necessary to evaluate the status of soil fertility in Tirtomoyo District in order to be used in the effort to provide and increase food sustainability for Wonogiri region and able to increase the economy level and income for the farmers. The results showed that the soil fertility status in all areas of Tirtomoyo District classified into the low category. This is due to the low value shown in almost all observation parameters; Cation Exchange Capacity (CEC); Base Saturation (BS); Organic Carbon; Total P and K levels. The limiting factor of soil fertility status caused by a very low Total P value of 2.16 mg 100 g-1 to 14.19 mg 100 g-1, and Organic Carbon which is low with 0.4% to 1.7%.
