ABSTRACT For the development of nutrient budget models to recommend lime and fertilizers for agricultural and forestry crops, curves of plant growth and nutrient accumulation are required. Information about how nutrients are partitioned between the different plant organs is also necessary, but still scarce for pine in Brazil. This study evaluated the growth, biomass partitioning, and nutrient dynamics in pine forests in southern Brazil. To this end, we assessed unthinned 2, 4, 6, and 8-year-old stands of Pinus taeda L.

Nutrition and crop yield can be affected by chemical modifications of the soil owing to lime and phosphogypsum surface application. The purpose of this study was to evaluate the effects of surface application of lime and phosphogypsum, at the establishment of a no-tillage system, on nutrition and grain yield of black oat, in a dry-winter region, in area previously used with conventional tillage. The experiment was carried out in 2003 and 2004, on a Haplorthox in Botucatu County, São Paulo […]
