In order to grow soybeans in cerrado soils it is necessary a previous, reduction of soil acidity and to build up the soil fertility. It is recommended the application of limestone to raise the soil pH up to the range between 5,5 and 6,0 or to increase base saturation up to 50%. The chemical constraints for root growth in the subsurface soil layers, such as the high aluminum saturation and/or calcium defficiency, can be overcome by the addition of gypsum. The recomended levels of gypsum vary from 700 kg/ha for sandy soils to 3200 kg/ha for heavy clayey soils. Fertilizers to supply phosphorus and potassium are recommended according to their availability in the soil determined by chemical analysis. Critical levels for those nutrients as well as the fertilizers recommendations are presented and vary with soil clay content. Alternatives for these aplications are offered. As for the micronutrients, the fertilizers recommendations are based on their availability detected either by plant or soil analysis. The most common deficiency is related to zinc. There are, also, some indications for boron and copper defficiencies after a few years of cropping. |

Fusarium kalimantanense is a genetic lineage of Fusarium oxysporum f. sp. cubense (Foc) and belongs to the Fusarium oxysporum species complex (FOSC). This pathogen is a causative agent of Panama disease, an infection that has caused damage to the banana crop worldwide. Bacillus sp. (LPPC170) showed preliminary antagonist activity against F. kalimantanense (LPPC130) in vitro tests from the cultivation of axenic culture and co-culture with inhibition of mycelial growth of phytopathogen of 41.23%. According to these findings, volatile organic compounds (VOCs) emitted from Bacillus sp. were obtained by solid-phase microextraction and identified by gas chromatography coupled with a mass spectrometer (GC–MS). The multivariate data analysis tool (PLS-DA and Heatmap) identified short-chain organic acids as the main antagonistic VOCs responsible for inhibiting the mycelial growth of LPPC130. Acetic acid, propanoic acid, butanoic acid, valeric acid, and isovaleric acid exhibited a strong inhibitory effect on the mycelial growth of LPPC130, with inhibition of 20.68%, 33.30%, 26.87%, 43.71%, and 53.10%, respectively. Scanning electron microscopy revealed that VOCs caused damage to the vegetative and reproductive structures of the fungus. These results suggest Bacillus LPPC170 as an excellent biocontrol tool against the phytopathogen causative agents of Panama disease. |
