Development and Rainfed Paddy Soils Potency Derived from Lacustrine Material in Paguyaman, Gorontalo
Rainfed paddy soils that are derived from lacustrine and include of E4 agroclimatic zone have many unique properties and potentially for paddy and corn plantations. This sreseach was aimed to: (1) study the soil development of rainfed paddy soils derived from lacustrine and (2) evaluate rainfed padd...
