Soil Quality Engineering Using Vermicompost and its Effect on the Corn (Zea mays L.) Production in Coastal Area

Oleh: Riwandi, Riwandi, Hasanudin, Hasanudin, Gusmara, Herry

The low quality of Entisol is caused by low availability of nitrogen, phosphorus, and potassium as well as low soil pH, so the addition of vermicompost is necessary. The purpose of this study was to determine the effect of vermicompost application on soil quality and to obtain the highest vermicompo...

Response Macronutrient Content of Saline-Resistant Paddy to the Saline Source Distance

Oleh: Putra, Aditya Nugraha, Adelyanti, Martiana, Sitorus, Albert Fernando

The impact of salinity on paddy production in Indonesia was pronounced with an average decline of 6.83% (2015-2019). Salinity interferes with macronutrients' absorption into plants, causing stunted growth (salinity contributed to a 42% decrease in paddy production). One solution to solve the salinit...
