“…However, most photosynthates produced by Guinea grass plants grown with S limitation were allocated to the roots. Similar results have been shown in S‐limited alfalfa ( Medicago sativa ) (Wang et al ., ) and beans ( Phaseolus vulgaris cv. Zlota saxa) (Juszczuk and Ostaszewska, ).…”

Forage plants constitute the primary food source for ruminants, and their aboveground growth and belowground growth depend on mineral nutrient supply. The objective of this study was to identify and quantify variation in morphology, production and nutritional status in Panicum maximum cv. Tanzânia and Stylosanthes guianensis cv. Mineirão grown with varying levels of S availability. In an experimental setting, plants of both species received rates of S calculated to reflect suboptimum, adequate and excessive levels of the element. S had a direct effect on morphology and production in both species. S limitation altered the allocation of photosynthates between the aboveground and belowground portions of Guinea grass and stylo, and was associated with lower root dry mass production. Guinea grass plants increased root surface area as an adaptive mechanism when S was limiting in the growth medium. The relative chlorophyll index of recently expanded leaves was correlated with aboveground dry mass production. After the initial growth, Guinea grass and stylo plants showed similar S requirements and use efficiency to achieve the maximum of aboveground productivity, although leguminous plants have a substantially higher capacity for store S in the shoot tissue as compared to gramineous plants growing under similar availability of S in the medium. While applying S was necessary for increasing dry mass production in both species, planting these species together is a promising strategy for guaranteeing high yields of forage with a nutritional value that satisfies the S requirements of ruminants.

“…Sheep manure is the only source for soil fertilisation in Inner Mongolian grassland; about 40% of sheep excrement is deposited in stock camp areas and is spread directly onto the soil surface after composting . Previous studies in the Xilin River basin focused on the impacts of cultivation, soil types, grassland communities, and grazing on fluxes of CO 2 , CH 4 , and N 2 O (Dong et al 2000;Wang 2001;Wang et al 2001;Hu et al 2003;Wang et al 2003b;, and have suggested that the Inner Mongolian grasslands are a sink of CH 4 and a source of N 2 O (Wang et al 2005). Wang et al (2001) found that CH 4 uptake increased greatly while N 2 O emission decreased significantly when grassland was grazed moderately (4 sheep ha -1 ).…”

Excrement patches of grazing animals play an important role in greenhouse gas (GHG) fluxes due to the high nitrogen (N) and available carbon (C) deposited in small areas, but little information is available for the effect of excrement in the Inner Mongolian grassland (43°26 N, 116°40 E). To elucidate the effect of grazing sheep urine, fresh dung and compost on fluxes of methane (CH 4 ), carbon dioxide (CO 2 ), and nitrous oxide (N 2 O), a short-term field study (65 days) was carried out in the typical grassland of Inner Mongolia with the optimised closed chamber/GC technique. Compared with the control, cumulative net CH 4 consumption decreased 36, 31, and 18% from urine, fresh dung, and compost plots, respectively; net CO 2 -C output increased by 6.5, 1.5, and 1.2% from urine, fresh dung, and compost treated soil, respectively; about three times as much N 2 O-N was emitted from urine and the fresh dung treatments during 65 days. Nitrous oxide emission was positively correlated with CO 2 emission (R = 0.691, P < 0.01) and water-filled pore space (R = 0.698, P < 0.01). The percentages of N 2 O-N loss of applied-N were 0.44 and 1.05% for urine and fresh dung, respectively. Our results suggest that in autumn in the degraded grassland of Inner Mongolia, the effect of sheep excrement may be ignored when evaluating the total GHG emissions.

“…Alfalfa crops have a greater demand for S than annual crops such as cereals. Sulfur nutrition of alfalfa is important, because its application not only increases yields but also improves the production of protein by legume crops (Wang et al 2003). Legumes tend to be deficient in the S-containing amino acids cysteine and methionine.…”

Alfalfa crops were grown in the field at the University of Ankara (473939 E, 4385149 N), over two seasons between 2001 and 2003 with sulfur (S) supplied at two different rates. The experimental design was a randomized complete block with five replicates and three cutting dates in each season. Sulfur was applied at rates of 0 (control), 160 (S 1 ), and 240 (S 2 ) kg ha 21 as gypsum. Alfalfa hay was harvested three times each year, and the concentrations of elements in the hay were measured by polarized energy dispersive x-ray fluorescence (PEDXRF). Sulfur fertilization increased S concentrations and improved alfalfa hay yield for both years. Applied S slightly reduced phosphorus (P) and magnesium (Mg) concentrations in the first year and had no significant effect on the potassium (K) and calcium (Ca) concentrations of alfalfa hay for either year. The highest S (240 kg ha 21 S) level increased sodium (Na) concentrations in the first year but decreased them in the second year. Sulfur application also decreased chloride (Cl) concentration in the first year. Molybdenum (Mo) concentration of the alfalfa was significantly reduced by S 1 treatment in year 1. Iron (Fe) concentration was increased by S 2 treatment in the 2264 second year, and zinc (Zn) concentration was increased by S 1 treatment in the first year. However, applied S had no effect on manganese (Mn), copper (Cu), titanium (Ti), vanadium (V), cobalt (Co), nickel (Ni), barium (Ba), uranium (U), and lead (Pb) concentrations for either year. Applied S decreased aluminum (Al) and silicon (Si) and increased bromine (Br) and rubidium (Rb) concentrations of alfalfa in the first year. In addition, strontium (Sr) concentration was increased by S 2 treatment in the first year but was decreased in the second year. The stage of cutting greatly affected mineral concentrations. Compared with the first cutting, S concentrations were higher in the second and third harvest for both years. In general, the concentrations of P, Mg, Na, Cl, Mo, Ti, V, Br, Co, Ba, Sr, Rb, U, and Pb were increased, whereas the concentrations of Fe, Zn, Mn, Cu, and Ni were decreased with later cutting. The concentrations of K and Ca did not vary between cuts.
