Applications for long periods of organic animal waste as a source of nutrients to crops can contaminate the soil and the surface and subsurface waters. This study aimed to evaluate how the utilization of organic waste, after successive applications, affects P fractions in the soil and consequently environmental contamination. deep bedding and NPK fertilizer for eight years (urea + triple superphosphate + potassium chloride) provided accumulations of P fractions in the soil that were above the necessary for a proper nutrition to plants considering the available P fractions (AER + organic NaHCO 3 + inorganic NaHCO 3 ) in the soil. In addition, they showed that the use of swine deep bedding, followed by pig slurry, means higher levels of available P fractions in the soil. In this sense, the establishment of a dosage of organic waste to meet the nitrogen need of crops is not an environmentally appropriate parameter. It may cause P accumulation in the soil, increased absorption ability of plants and soil support, contributing to environmental contamination.

“…Phosphorus is one of the most essential plant nutrients and its accumulation in alfalfa is significantly improved by supplying P-compost at 30 t ha -1 . There is considerable evidence in the literature dealing with the increase of phosphorus solubility following organic material application (Sanyal and De Datta 1991). Concerning the potassium accumulation, results showed inversely behavior among the first and second crop seasons under the different amendment treatments (Fig.…”

Purpose Date palm (Phoenix dactylifera L.) is one of the predominant fruit trees grown in oases ecosystems (Southern Mediterranean regions) and produces several wastes during practicing cultivation since fruit and bunch thinning is frequently applied. Yet, the valorization of date palm wastes as bioresources has received little attention. The main objective for the present research is to assess palm trees compost (P-compost) as organic fertilizer for alfalfa (Medicago sativa L.). Methods The experiment was carried out in an experimental field involving four replicates and three soil amendment treatments (1) control, conventional mineral fertilizer diammonium phosphate, (2) 30 t ha -1 of cow manure, and (3) 30 t ha -1 of palm tree compost (P-compost). Plots were planted on with alfalfa and the measurements of studied traits (growth, yield, seed yield and minerals uptake) were determined for two crop seasons (2010 and 2011). Results Compared with untreated soil, the palm compost application at 30 t ha -1 improved significantly both organic matter and water retention capacity of the soil and decreased the electrical conductivity (-70%).Furthermore, palm compost supply significantly increased fresh biomass production of alfalfa by 21 and 28%, respectively, during the first and second seasons. Also, it enhanced the grain yield and growth rate (stem length and leafs expansion) of this species. At the first crop season, the palm compost application had a positive impact on minerals nutrition compared to the control treatment, with improving rates of ? 32% for phosphorus, ? 25% for potassium and ? 6% for nitrogen. In addition, these contents were higher than in plants grown under cow manure amendment. However, at the second season, the palm compost improved only P and N contents. Conclusions This preliminary finding suggests that palm compost at moderate dose (30 t ha -1 ) could be highly beneficial for forage plant yield.

“…O papel desempenhado pela matéria orgâni-ca é ambivalente, já que ela tanto pode adsorver o fósforo como também bloquear os sítios de adsorção que ocorrem nas superfícies das argilas e dos óxidos de ferro e alumínio (SANYAL e DE DATTA, 1991). Quanto à mineralogia e características de cristalinidade dos óxidos de ferro e alumínio, vários estudos têm mostrado que a capacidade de adsorção de fósforo parece estar relacionada com a área superficial do óxido (FON-TES e WEED, 1996) e com o seu grau de cristalinidade.…”

Neste estudo foram avaliadas possíveis correlações entre atributos físicos e químicos do solo e a capacidade máxima de adsorção de fósforo (CMAP) em solos com argila de atividade baixa de diferentes regiões do Brasil, sendo utilizadas amostras de horizontes superficiais (A) e subsuperficiais (B) de 16 perfis de solos. As doses para a determinação da CMAP foram calculadas com base no teor de fósforo remanescente e variaram de 0 a 135 mg.L-1. A partir dos dados obtidos foram então construídas isotermas de adsorção de Langmuir. Foram feitas correlações entre CMAP e os teores de argila, de carbono orgânico, ki, kr, superfície específica, teor de alumínio determinado por ataque sulfúrico e teores das diferentes formas de ferro extraível. Foi observada grande variação nos valores de CMAP para o horizonte superficial (48 a 1429 mg.kg-1) e para o horizonte subsuperficial (455 e 1.667 mg.kg-1). Os coeficientes de correlação demonstraram haver uma associação significativa entre a CMAP e o teor de argila dos solos, ferro e alumínio, determinados pelo ataque sulfúrico e ferro extraído com ditionito-citrato-bicarbonato (DCB). A análise de regressão múltipla mostrou bom ajuste aos valores da CMAP com base em atributos dos solos estudados.
