“…Size of alignment was 386 bp, and gaps were omitted. Bootstrap values were based on 2,000 trials correlated with low LNB density and diversity (Andrade et al 2002;Bala et al 2002;Grewal and Williams 2003). Although most of the studied soils had high Al content (Table 2) with significant differences among LUSs, it seems that they were not affecting LNB communities.…”

Understanding native communities is a crucial step for the management of biological nitrogen fixation, since they may be either a source of efficient strains or a limiting factor when efficient strains need to be introduced. This work aimed to evaluate the density, diversity and efficiency of Leguminosae nodulating bacterial (LNB) communities and their component strains in soils under various land use systems (LUSs): pristine forest, agriculture, pasture, agroforestry, young secondary forest, and old secondary forest,. The LNB communities were trapped from these soils by using the promiscuous host siratro under controlled conditions. We also studied their relationships with physical and chemical attributes of the soil. Agroforestry and agriculture soil samples induced the highest number of nodules in siratro, while forest soil samples induced the lowest number of nodules. No relationship was found between LNB and Leguminosae species diversity in the LUSs. The soil chemical variables that were most related to differences in nodule number and shoot dry matter weight of plants inoculated with soil suspensions of the LUSs were, respectively: Ca 2+ , Mg 2+ , base saturation, exchangeable bases and Cu 2+ ; and pH, cation exchange capacity, B, Cu 2+ and clay. Although, LNB communities from all LUSs were efficient under controlled and similar conditions, they were found to be composed of strains with variable efficiency: inefficient, efficient, highly efficient and superior efficiency. Efficient strains occurred at the highest frequency in all LUSs. The isolated strains presented similar and new sequences that were phylogenetically related to well known LNB genera in α-and β-Proteobacteria. Unusual genera in these branches, as well as in other branches, which are probably endophytic bacteria, were also isolated from nodules. These data support siratro as a useful trap species to study the LNB biodiversity of diverse ecosystems in tropical soils. The fact that the highest diversity and nodulation were seen in managed systems such as agriculture and agroforestry suggests a high resilience of LNB communities to changes in land use after deforestation in a region where large forest areas are still preserved and can be a source of propagules.

“…Liming is a necessary ameliorative practice in the process of fertility increase of acid soils (Grewal and Williams, 2003;Dugalic et al, 2006). The application of lime caused the decrease of Al and Mn toxic concentrations, as well as the decrease of extremely high Fe concentrations in the soil and raspberry leaves (Sikiric et al, 2009).…”

Raspberries thrive best in an acid soil. However, if the soil pH is lower than 5.6, lime application is necessary. In this study the effects of lime and dolomite application in combination with NPK 15:15:15 fertilizer (600 kg ha -1 ) on the macroelement contents (N, P, K, Ca, and Mg) in an extremely acid soil (pH 4.35) and raspberry leaves were evaluated during a three-year period. Optimal pH value for raspberry cultivation (5.84) was achieved with the application of 9 t ha -1 of lime. The mineral nitrogen (NH 4 + NO 3 )-N content and P content in the soil after liming increased significantly, but P concentration stayed below the optimal values. Additionally, no changes were noted in K concentration in the soil. The Ca concentration increased significantly in all treatments, while the Mg content increased significantly only in the treatment with dolomite. The N content in the raspberry leaves increased, but K content decreased after liming. There was no change in P content in the leaves affected by liming. Lime increased Ca content in the leaves above the optimal values, while it did not affect the initially optimal Mg content in the leaves. After liming and NPK fertilization, the concentrations of N, P and K in the leaves were still below the optimal values, indicating a need for the combination of higher rates of fertilizer with lime in raspberry cultivation in very acid soils.Additional key words: amelioration of acid soils; macronutrient concentration; raspberry cultivation; Rubus idaeus L. ResumenOptimización del contenido en macroelementos en hojas de frambueso mediante encalado en suelos muy ácidos Los frambuesos crecen mejor en suelos ácidos. Sin embargo, si el pH del suelo es inferior a 5,6, es necesario aplicar cal. En este estudio se evaluaron durante un período de tres años los efectos de aplicar cal y dolomita, en combinación con fertilizantes NPK 15:15:15 (600 kg ha -1 ), en el contenido de macroelementos (N, P, K, Ca y Mg) en un suelo extremadamente ácido (pH 4,35) y en hojas de frambueso. El pH óptimo para el cultivo del frambueso (5,84) se logró con la aplicación de 9 t ha -1 de cal. En el caso del suelo, después del encalado el contenido en nitrógeno mineral (NH 4 + NO 3 )-N y de P aumentó significativamente, pero la concentración de P se mantuvo por debajo de los valores óptimos; además, no se observaron cambios en la concentración de K; la concentración de Ca aumentó significativamente en todos los tratamientos, pero el contenido de Mg aumentó significativamente sólo en el tratamiento con dolomita. En las hojas de frambueso, después del encalado el contenido de N aumentó, pero el contenido de K disminuyó; no hubo cambios en el contenido de P; el contenido de Ca aumentó por encima de los valores óptimos, mientras que no se afectó el contenido inicial óptimo de Mg. Después del encalado y la fertilización NPK, las concentraciones de N, P y K en las hojas estaban todavía por debajo de los valores óp-timos, lo que indica la necesidad de combinar mayores tasas de abono con cal en el cultivo...

“…In acid soils, many nutrients are not readily available to plants, although they are present in sufficient quantities (Su and Evans, 1996). Satisfactory crop yields on acid soils can be achieved by soil liming (Grewal and Williams, 2003). However, the effect of lime application at 3 t*ha -1 before alfalfa seeding on alfalfa yield decreases over the years (Lazarević, 2011).…”

Soil acidity is one of the most common reasons for low yields of forage crops. This paper analyzes the long-term effect of liming (control -without CaO; 3 t*ha -1 CaO; 6 t*ha -1 CaO) applied to an acid soil (pHH2O 4.8) before stand establishment on the productivity of a mixture of red clover (Trifolium pratense L.) and tall oat grass (Arrhenatherum elatius L.) during the third year of production. Soil liming significantly increased hay yields in the first and second cuts by 17-25% and 46%, respectively, which resulted from an increase in the total yield and dry matter content of forage. In the third cut, soil liming had no effect on forage and hay yields due to the lower amount of precipitation in the second part of the growing season. Both lime application rates led to a significant reduction in the percentage of red clover in the first and second cuts, thus favoring the percentage of tall oat grass. In the third cut, only the percentage of weeds was lower in both lime treatments, as it decreased by more than 55% compared to the control.Keywords: forage yield, red clover, soil liming, tall oat grass Sažetak Kiselost zemljišta je jedan od najčešćih razloga za niske prinose krmnih useva. U radu je analiziran produžen uticaj primene kalcizacije (kontrola -bez CaO; 3 t*ha -1 CaO; 6 t*ha -1 CaO) na kiselom zemljištu pH 4,8, pre zasnivanja useva, na produktivnost smeše crvene deteline (Trifolium pratense L.) i francuskog ljulja (Arrhenatherum elatius L.) tokom treće godine proizvodnje. Kalcizacija zemljišta je uticala na značajno povećanje prinosa sena u prvom i drugom otkosu za 17-25%, odnosno 46% po redosledu. To je posledica povećanja ukupnog prinosa krme i sadržaja suve materije u krmi. U trećem otkosu, kalcizacija zemljišta nije ostvarila Agriculture, 2018, 19(2), p.482-489 482 uticaj na prinos krme i sena, zbog manje količine padavina u drugom delu vegetacije. Primena oba nivoa kalcizacije zemljišta je uticala na značajno smanjenje udela crvene deteline u prvom i drugom otkosu, na račun povećanja udela francuskog ljulja. U trećem otkosu je jedino udeo korova bio manji na obe varijante kalcizacije za više od 55% u odnosu na kontrolu.
