Performance The Red Onion (Allium ascalonicum L.) by Husk Charcoal and Fertilizer K Application

Oleh: Rakhmiati, Rakhmiati, Handayani, Etik Puji, Jamaludin, Jamaludin

The cultivation of Red Onions (Allium ascalonicum, L.) in paddy fields needs to be investigated further because paddy fields have constraints on the soil physical and chemical properties, such as soil structure, drainage, pH, and nutrient availability. The application of husk charcoal and K fertiliz...

Changes of Soil Physical and Chemical Characteristics of Vertisol by Organic Matter and Sands Applications

Oleh: Mindari, Wanti -, Sasongko, Purnomo Edi, Santoso, Setyo Budi

Vertisol has a clay texture, high micropores, and high water and nutrient absorption ability. The high water content of Vertisol causes the air to decrease, thus inhibiting root development. Stretching of the Vertisol structure is expected to increase soil porosity and reduce ion and water absorptio...
