Chemical Variation in Soil Fertirrigated With Effluent

Purpose: The aimed witch of this study was to evaluate the chemical changes in soil cultivated with Panicum maximum cv. Mombaça grass, when submitted application different doses dairy effluent (ARL), sodium as a limiting factor.
 
 Method/design/approach: Was applied ARL an area grass order provide at concentrations 75, 150, 300 and 600 Kg ha-1. Soil samples were collected depths times, having determined active acidity (pH) phosphorus (P), potassium (K), organic matter (MO) cation capacity (CTC).
 Results conclusion: Regarding initial conditions, pH, MO CTC Did not show significant Variations. However, there are reductions P increases K concentration. For Environmental Conservation, providing kg ha-1 year-1 may become Recommendation for treatment reuse these effluents, relation did variations. environmental conservation, recommendation effluents.
 Research implications: In relevant literature, technical that restricts effluents 150 sodium, halophyte cultures, has been used interchangeably, making it difficult use effluent. research concluded can be fertigation rate up ha-1sodium.
 Originality/value: This indicates increase amount delivered through effluents.
