Pasture degradation is a concern, especially in susceptible sandy soils for which strategies to recover them must be developed. Microbiological and biochemical soil health indicators are useful in the guindace of soil management practices and sustainable soil use. We assessed the success of three Panicum maximum Jacq. cultivars in the reclamation of a pasture in a sandy Typic Acrudox in the northwest of the state of Paraná, Brazil, based on soil health indicators. On a formerly degraded pasture with Urochloa brizantha (Hochst. ex A. Rich.) R.D. Webster, a trial with three P. maximum (cv. Massai, Tanzânia, or Mombaça) was conducted. Lime and phosphate were applied at set-up, and mineral N and K as topdressing. A remnant of degraded pasture adjacent to the...

Soil quality indicators in a rhodic kandiudult under different uses in northern Parana, Brazil. Repositório Alice
KUWANO, B. H.; KNOB, A.; FAGOTTI, D. S. L.; MELEM JUNIOR, N. J.; GODOY, L.; DIEHL, R. C.; KRAWULSKI, C. C.; ANDRADE FILHO, G.; ZANGARO FILHO, W.; TAVARES FILHO, J.; NOGUEIRA, M. A..
Sustainable use of soil, maintaining or improving its quality, is one of the goals of diversification in farmlands. From this point of view, bioindicators associated with C, N and P cycling can be used in assessments of land-use effects on soil quality. The aim of this study was to investigate chemical, microbiological and biochemical properties of soil associated with C, N and P under different land uses in a farm property with diversified activity in northern Parana, Brazil. Seven areas under different land uses were assessed: fragment of native Atlantic Forest; growing of peach-palm (Bactrys gasipaes); sugarcane ratoon (Saccharum officinarum) recently harvested, under renewal; growing of coffee (Coffea arabica) intercropped with tree species; recent...
