Nitrate and potassium dynamics in profiles of soils cultivated with fertigated sugarcane crops.

Nitrate and potassium dynamics in profiles of soils cultivated with fertigated sugarcane crops.

The objective of this study was to evaluate the distribution of NO3- and K+ in the profile of soils cultivated with sugarcane crops, after application of different nitrogen (N) and potassium (K2O) rates via subsurface drip fertigation, in Teresina, PI, Brazil. The experiment was conducted at the experimental area of Embrapa Meio-Norte, using a randomized block design with four replications.
