Improvement of Soil Chemical Properties of Typic Hapludult After Application of Organic and Inorganic Fertilizers

Oleh: Mubarok, Syariful, Kusumiyati, Kusumiyati, Muhardiono, Iman

Tuberose (Polyanthes tuberosa L.) is a potential flowering plant that will be developed in Jatinangor, West Java, Indonesia. However, the characteristics of Typic Hapludult soil in Jatinangor , i.e. clay texture, acidic pH, and high amount of total-P but low in available-P cause the tuberose difficu...

Improvement of Latex Quality Using Locally-Produced Organic Fertilizer from Rubber Processing Sewage Sludges

Oleh: Riwandi, Riwandi, Prasetyo, Prasetyo, Hasanudin, Hasanudin

Most of rubber plants in Indonesia are cultivated in highly-weathered soils; therefore, their annual productions are relatively low with the low quality of latex. The aim of this reseach was to increase the latex quality from a rubber plantation grown on low fertility soils by applying a locally-pro...
