Savannah floodplains are a natural agroecosystem located in the eastern plains of Colombia, with soils considered to be low fertility. This assumption has not been rigorously validated by direct experimental studies. The aim study was analyze soils’ physicochemical characteristics “banks” and “lows”, which physiographic positions, from floodplain savannah Arauca, Colombia. Soil samples were col...

Rice seedlings and weeds emerge concurrently in direct-seeded rice (DSR) production systems, while there is no flooding water to inhibit weed germination, emergence development at crop emergence. Because of this, are considered the biggest living barrier DSR significantly reduce yield. The purpose research was devise an approach for management cultivated under various agroecosystems, optimizing...
