“…However, plant N values were very low. Although critical values for plant N in herbage are not often cited, Bolton et al (1976) and Goh and Kee (1978) reported critical deficient levels for Lolium perenne of 25 g kg -t and 29 g kg -5, respectively; Benton Jones et al (1991) reported a sufficiency range for optimum yields of between 45 and 50 g kg-1. Over the entire experimental period of the present study, the compost was a poor N-supplying material to ryegrass, but it provides relatively large amounts of inorganic N, particularly with compost rates of 40 and 50 t ha -~ (Table 3).…”

The use of composted municipal refuse on agricultural land requires prior knowledge of the interactions among compost, soil, and plants. Research into the availability of N in highly matured municipal refuse compost is particularly important considering the current concern about groundwater contamination by NO3-N. A greenhouse pot bioassay was conducted to determine the percentage of short-term apparent bioavailable N of a highly matured refuse compost and its relative efficiency in supplying inorganic N to the soil-plant system in comparison with NH4NO 3. Municipal refuse (after 165 days of composting) was applied at rates equivalent to 10, 20, 30, 40, and 50 t ha-1 to a ferrallitic soil from Tenerife Island (Andeptic Paludult). NH4NO 3 was applied at rates equivalent to the total N content of the compost treatments. Perennial ryegrass (Lolium perenne L.) was grown in 3-kg pots and the tops were harvested at regular intervals after seedling emergence. The compost increased dry matter yield, soil mineral N, and plant N uptake proportional to the applied rate. These increases were significantly higher than the control at an application rate of 20t ha-1. After 6 months the apparent bioavailable N ranged from 16 to 21~ The relative efficiency was 43~ after 30 days. This suggests that large inputs of inorganic N into soil can be obtained with high rates of this kind of compost, with a potential for NO3-N contamination. However, applied at moderate rates in our bioassay (<50t ha-l), compost showed a low N-supplying capacity to ryegrass, i.e. a small fraction of the mineralized compost N was used by plants in the course of time. This was ascribed to a partial biological immobilization. This pattern of N availability in highly matured municipal refuse compost, positive net mineralization but partial immobilization, is similar to the pattern of N availability in biologically active soils and is therefore extremely interesting for the conservation of N in agro-ecosystems.

In an experiment to determine the effect of N and S fertilizer rates on yield and S uptake by cool‐season forage grasses, two cultivars of tall fescue (Festuca arundinacea Schreb.) and one of phalaris (Phalaris aquatica L.) were grown in greenhouse and field experiments on a Cahaba fine sandy loam (Typic Hapludult) at comparable fertility levels. Fertilizer rates in the greenhouse were 38, 75, 125, 175 ppm N and O, 5, 10, 20 ppm S. Nitrogen rates in the field were 85, 170, 280, 390 kg/ha; and S rates were 0, 11, 22, 44 kg/ha. Organic‐S content of foliage was about equal in greenhouse and field experiments; it progressively increased with higher N rates but not with S rates. Inorganic‐S content was much higher in the green. house experiment,. particularly with phalaris; it progressively decreased with N rates and increased with S rates. Phalaris accumulated potentially toxic levels (to ruminants) of sulfate in the greenhouse but not in the field. Greenhouse‐grown plants accumulated much higher levels of S than did field‐grown plants, probably because the field soil was able to retain only a portion of the fertilizer sulfate within the rooting zone of the soil profile.

“…Sulfur (S) as an essential element in the life processes of all living things is an important part of the proteins that are needed to sustain life in all biological organisms. S plays an important role in plant metabolism, crop yield and quality (Goh and Kee 1978;Droux 2004). S has been identified as a limitaing factor for production and quality of winter wheat in many countries, despite its relatively low requirement for wheat (Zhao et al 1999;Zhu et al 2010;Gallejones et al 2012).…”

Water shortage has threatened sustainable development of agriculture globally as well as in the North China Plain (NCP). Irrigation, as the most effective way to increase food production in dry land, may not be readily available in the situation of drought. One of the alternatives is to supply plants with enough nutrients so that they can be more sustainable to the water stress. The objective of this study was to explore effects of irrigation and sulphur (S) application on water consumption, dry matter accumulation (DMA), and grain yield of winter wheat in NCP. Three irrigation regimes including no irrigation (rainfed, I 0) during the whole growth period, once irrigation only at jointing stage (90 mm, I 1), and twice respective irrigation at jointing and anthesis stages (90 mm plus 90 mm, I 2), and two levels of S application including 0 (S 0) and 60 kg ha-1 (S 60) were designed in the field experiment in NCP. Results showed that increasing irrigation times significantly increased mean grain yield of wheat by 12.5-23.7% and nitrogen partial factor productivity (NPFP) by 21.2-45.0% in two wheat seasons, but markedly decreased crop water use efficiency (YWUE). Furthermore, S supply 60 kg ha-1 significantly increased mean grain yield, YWUE, IWUE and NPFP by 5.6, 6.1, 23.2, and 5.6% (across two wheat seasons), respectively. However, we also found that role of soil moisture prior to S application was one of important greater factors on improving the absorption and utilization of storage water and nutrients of soil. Thus, water supply is still the most important factor to restrict the growth of wheat in the present case of NCP, S supply 60 kg ha-1 with once irrigation 90 mm at the jointing stage is a relatively appropriate recommended combination to improve grain yield and WUE of wheat when saving water resources will be considered in irrigated wheat farmlands of NCP.
