In contrast to crops such as coffee, citrus and pineapple, there is little information about the use of liquid soil fertilizer for grain-producing crops such as soybean and maize and in pastures. To address this gap was developted a research at the Advanced Research and Development Center for Rubber Tree and Agroforestry Systems of the Agronomic Institute (IAC) of the São Paulo Agency for Agribusiness Technology (APTA), which is located in the Cerrado biome in the municipality of Votuporanga, São Paulo State, Brazil. This research gave rise to this book.
