The objective of this work was to access spatial variations of soils from experimental plots for integrated coconut production based on the detailed mapping of soils and the construction of contour maps of soil properties. Observations and measurements were formed and samples collected in small trenches and soil profiles. The amount of soil clay from small trenches was evaluated in the field by finger touch feeling. Physical and chemical analyses were performed in all samples. Particle-size-distribution (profiles), Al, Ca and […]
