The objective of this work was to evaluate the ability of soil management systems to change the contents and dynamics of soil carbon. Natural vegetation and systems composed of perennial tropical pastures, annual crops under conventional tillage and no-tillage systems, and pasture rotation with annual crops were evaluated in long-term experiments carried out in Dourados, Maracaju and Campo Grande, Mato Grosso do Sul state, Brazil. The experiments were set in a completely randomized block design, in Dourados and Maracaju, and in a randomized complete block design in Campo Grande. Contents and stocks of total C in soil and in soil organic matter (SOM) fractions were measured. The quality of SOM was estimated by the ratio of C in labile and nonlabile fractions, and expressed in the form of lability. Permanent pasture or pasture in rotation with crops increased C in the particulate fraction and the SOM lability. Lower rates of accumulation and of stocks of soil C were observed in systems explored only with annual crops, while higher values were recorded in systems with pasture.

The objective was to evaluate the yield of three soybean (Glycine max) varieties, each one growing in different year, using three fertilizer (Fosmag, 00-17-17, Yorin + KCl, ARAD + KCl, 02-27-20) rates: recommended, low and control. To conduct the experiment on Maracaju municipal district, Mato Grosso do Sul state Brazil, in an Oxisol, a randomized block design with five repetitions and eleven treatments (ten treatments + control) was used. The application of Fosmag and 00-17-17 formulation showed to be the best fertilizer to three varieties under experimental soil conditions.

The aim of this study was to determine the effect of different levels of crambe meal (CM) in the diet as a substitute for soybean meal on feed intake, growth performance, blood parameters, carcass characteristics and meat quality of lambs. A total of 80 sheep predominantly from the Texel breed, 40 male (23.3. ±. 0.98. kg) and 40 female (22.1. ±. 0.95. kg) lambs, were fed 0, 64, 128 or 192. g/kg dry matter (DM) CM in the total mixed diet. Intake of DM increased in parallel with the level of CM inclusion in the diet and there was no effect of CM on digestibility and weight gain. The feed to gain ratio decreased as levels of CM increased in the diet. Yields of carcass and commercial cuts were similar among diets. The proportion of muscle and the muscle to bone ratio tended to decrease with higher CM level in the diet. Male and female lambs responded similarly to CM levels except for subcutaneous fat where there was a greater decrease in carcass of male than female lambs with increasing CM dietary level. Chemical composition and quality of the longissimus dorsi were similar among diets. These data suggest that there are no ill effects on carcass quality and animal performance when CM is provided at up to 192. g/kg DM in the diet of growing lambs fed a forage to concentrate ratio of 350-650. © 2016 Elsevier B.V.

The objective of this work was to analyze the effect of grain moisture and crop yield spatial distribution on grain losses and quality during bean uprooting, collecting, threshing and separating process on a retirement-threshing machine. The work was performed in a 35 ha area under a central pivot irrigation system. Grain moisture on the uprooting and collecting process, the crop yield, the machine work speed, the grain losses during uprooting, collecting, threshing and separating process and the material-other-than-grain were measured. Grain losses and product quality displayed high variation over the area, showing the need for a specific regulation of the retirement-threshing machine on each case during the harvest, in function of the grain moisture and crop yield.

Sulphur is a component of protein and aminoacids in plants, being required in an expressive amount by leguminous, as function of high protein levels in these plants. Then, this work aimed to verify the influence of different sulphur sources on soybean grain yield. The experiment was carried out at the experimental area of Fundação MS, Maracajú, MS, in three consecutive years in a randomized block design with four replications, submitted to variance analysis of group experiments. The cultivars used were BRS-133 (2002/03 and 2003/04) and CD 202 (2004/05). As treatments, it was evaluated the application of sulfur as Simple Superphosphate, MAP sulphured + Sulfurgran, Sulfurgran, elemental sulphur, granulated gypsum, Fosmag 509M6, agricultural gypsum throwed on surface, and a witness without application. Soybean crop answer is positive to soil applied sulphur in Brazilian cerrado soils, in most of the time to obtain higher grain yield. Most of S sources were efficient to provide this nutrient for soybean, highlighting the applications of MAP Sulphured + Sulfurgran, Formag 509M6 and agricultural gypsum, that promoted the highest soybean grain yield. Elemental sulphur was not efficient to provide available S for the crop.
