Abstract

ABSTRACT Adequate use of poultry manure under tropical conditions can contribute to the recovery of degraded soils. The objective was to evaluate the effect of poultry manure on structure and some indicators of fertility in tropical soils such as Inceptisol Mollic Eutrudept Ustept, Inceptisol Ustept, Rhodic Eutrustox, Pellic Vertisol Typic Hapluster and Aquic Plinthic Kandiustalf. Five experiments were established under controlled conditions, one in each soil, using samples of 0–20 cm soil depth. The treatments were: control without the application of poultry manure, 2 t ha−1 of poultry manure, 4 t ha−1 of poultry manure, 6 t ha−1 of poultry manure, 8 t ha−1 of poultry manure, 10 t ha−1 of poultry manure. The results showed increases in pH and organic matter that contributed to greater availability of phosphorus and potassium, as well as improvements in soil structure and stability. The best results of the application of poultry manure were obtained using 6 t ha−1. The R2 values of 0.93 (pH versus assimilable potassium), 0.77 (organic matter versus structure factor) and 0.67 (pH versus assimilable phosphorus) indicated that poultry manure can achieve effects on the recovery of degraded soils regardless of the type and content of clay.

家禽粪便对热带土壤结构和某些肥力指标的影响

摘要：在热带条件下充分利用家禽粪便有助于恢复退化土壤。目的是评估家禽粪便对热带土壤结构和一些肥力指标的影响，如Inceptisol Mollic Eutrudept Ustept、Inceptisor Ustept，Rhodic Eutrustox、Pellic Vertisol Typic Hapstluster和Aquic Plinthic Kandiustalf。在受控条件下建立了五个实验，每个土壤一个，使用0–20 cm土壤深度的样本。处理为：不施用家禽粪便的对照，2 t ha−1家禽粪便，4 t ha−2家禽粪便，6 t ha−3家禽粪便，8 t ha−4家禽粪便，10 t ha−5家禽粪便。结果表明，pH值和有机质的增加有助于提高磷和钾的有效性，并改善土壤结构和稳定性。施用家禽粪便的最佳结果是使用6t ha−1。R2值0.93（pH与可同化钾）、0.77（有机质与结构因子）和0.67（pH与可同化磷）表明，无论粘土的类型和含量如何，家禽粪便都能对退化土壤的恢复产生影响。

期刊介绍： rchives of Agronomy and Soil Science is a well-established journal that has been in publication for over fifty years. The Journal publishes papers over the entire range of agronomy and soil science. Manuscripts involved in developing and testing hypotheses to understand casual relationships in the following areas: plant nutrition fertilizers manure soil tillage soil biotechnology and ecophysiology amelioration irrigation and drainage plant production on arable and grass land agroclimatology landscape formation and environmental management in rural regions management of natural and created wetland ecosystems bio-geochemical processes soil-plant-microbe interactions and rhizosphere processes soil morphology, classification, monitoring, heterogeneity and scales reuse of waste waters and biosolids of agri-industrial origin in soil are especially encouraged. As well as original contributions, the Journal also publishes current reviews.
