Utilizing Coal ash and Lignite Enriched-Compost to Improve Chemical Properties of Ultisols
Fajarindo, Fadil, Suwardi, Suwardi, Iskandar, Iskandar
Continuous monoculture activities can cause soil degradation, leading to low pH, organic matter content, and nutrient deficiencies in Ultisols. Compost has been used to improve soil fertility. Unfortunately, its effectiveness has been limited due to rapid decomposition in the humid tropic area. This...

Release Pattern of Nitrogen and Potassium from Controlled Release Fertilizer (CRF) in the Soil
Suwardi, Suwardi, Suryaningtyas, Dyah Tjahyandari, Saputra, Hens
Nitrogen (N) and potassium (K) are macronutrients that plants need for better growth and yield. However, they are readily lost from the soil through volatilization, denitrification, and leaching, aside from being absorbed by plant roots. Thus, a Controlled Release Fertilizer (CRF) may be formulated ...
