The effects of the original soil pH (4.4) and adjusted to 5.0, 5.5, 6.0 and 6.5 with CaCO3, to 6.0 withMgCO3, to 5.5 with CaCO3 plus CaSO4, and CaSO4 at original pH (4.4) on the root growth and mineral contents of four citrus rootstocks (Volkamer lemon, Rangpur lime, Cleopatra mandarin, and Sunki mandarin) were determined in a nursery experiment. The soil was an Oxisol (Typic Haplorthox, U. S. Soil Taxonomy) with acid pH CaCl2 of 4.4., low base saturation and high Al saturation. Root growth increased with increasing soil pH adjusted with CaCO3, CaCO3 plus CaSO4, and CaSO4 treatments. The MgCO3 treatment had no effect on root growth. The citrus rootstocks growth followed the order: Volkamer =Rangpur lime > Cleopatra > Sunki. The Volkamer and Rangpur rootstocks showed the best performance in acid soil conditions and the highest response to lime. Sunki mandarin was the poorest rootstock under acid soil condition. The concentrations of N, P, K, Mg, Cu, and Zn in root and leaf tissues were unchanged with soil amendments, While ca increased and Mn decreased with increasing soil pH adjusted with CaCO3. Optimumroot growth was associated with the two soil acidity variables: decreased Al concentration and improved Ca nutrition. |

In order to determine reasonable planting time and zoning for soybean in the regions of Northeast and Southeast Pará, water ballance simulation and a zoning approach were conduced. Water balance was analysed by using combinations of 12 planting time, soil available water and two crop varieties. In adition, field informations related to soil texture, plant phenology and crop water consumption were also analysed. From water balance several paramaters were determined including the moisture satisfaction index (HNSI) and climatic risks. The zoning approach was based on two aspects: the climatic risks as an indicator to determine the climatic suitability classes for soybean and the geographic system analyses(GIS) for spatial analysis. The overall results show 72 zoning maps indicanting favorable planting time and suitable areas for soybean crop. |
