“…In this work, addition of biochar and sludge to the soil with and without fertiliser, decreased the cellulose content of Coolatai grass. As discussed by Ward (1959) the chemical composition of forage may be altered through the use of fertilisers and it is very likely that the addition of nutrients through the biochar and sludge in the current work may have reduced the amount of cellulose in the grass. The highest hemicellulose content was in the grass cultivated under the SS treatment which is significantly different to the SBF treatment.…”

“…It appears that in case of all treatments where biochar was not applied, including fertiliser treatment, the crude protein content of the Coolatai plant does not meet the minimum requirements as a feed for livestock. Application of wastewater sludge biochar increased the amount of crude protein of Coolatai grass possibly because the biochar contains bioavailable nitrogen and phosphorus, which are directly involved as protein and nucleic acid forming constituents (Ward, 1959).…”

“…Davis ( 1951) suggested that plants growing on infertile soils supplied inadequate energy requirements for domestic and wild animal growth. Ward ( 1959) suggested that a balanced nutrient supply, whether at a low or high level, generally resulted in forage of approximately the same nutrient composition, but caused variation in seed yields. West and Meng ( 1966) found no significant differences in energy content of plant parts of willows (Salix spp.)…”

Important in the bioenergetics of granivores is the difference in energy content of seeds from plants grown on different areas within the organism's normal environment. To determine possible differences in energy content, seeds of nine species of plants (Solanum rostratum, Helianthus annuus, Rhus aromatica, R. glabra, Ambrosia trifida, Cornus drummondi, Symphoricarpos orbiculatus, Setaria lutescens, and Bromus japonicus) were collected from four distinct range sites. No differences were detected (except for Rhus aromatica) between mean energy content of seeds from the four sites. However, significant intraspecific differences (P < 0.05) were noted between means of energy content of seeds from different locations within the same range site.

“…[1,4,5] The soil nutrient status has been demonstrated to significantly affect energy distribution. Ward [7] suggested that a balanced nutrient supply whether at low or high level, generally resulted in forage of approximately the same nutrient composition, but yield varied.

A field experiment was conducted in Hangzhou, Zhejiang Province, P.R. of China in 1999 to investigate the quantitative caloric energy characteristics of two rice cultivars (Oryza sativa L.), early crop rice Jia yu 948 and late crop rice Jia yu 93390 were grown in different nitrogen levels and climate conditions. The two cultivars were grown with 0, 80, 120, 160, and 200 kg ha À1 of nitrogen fertilizer and in ample water and farming management activities. Analysis of caloric energy showed that significant differences occurred among treatments and plant organs in both rice cultivars. However, no significant differences occurred among same organs under different nitrogen treatments in both cultivars except for the panicles. The mean caloric energy of both cultivars increased with nitrogen fertilizer application. However, no optimal level of nitrogen fertilizer treatment with caloric energy was established, as there was still an increase in caloric energy even at 200 kg N ha À1 fertilizer treatment. Cultivar Jia yu 948 had a higher mean caloric energy of 4172 cal g À1 compared to 4117 cal g À1 of cultivar Jia yu 93390. There were significant differences in caloric energy among the plant organs. The ascending order of energy distribution was as follows; root, stem, husk, leaf, grains, and panicles. Of great interest is the relatively high amount of energy invested in the husks. This amount was similar to that of the leaf. There was a linear relationship between caloric energy and nitrogen application levels. The basic rice caloric values are 4058 cal g À1 , an increase in 1 kg N ha À1 of nitrogen (pure) resulted in an increase of 0.41 cal g À1 and 0.29 cal g À1 of dry weight in the cultivar Jia yu 948 and cultivar Jia yu 93390 respectively. Thus Jia yu 948 had a better utilization efficiency of nitrogen nutrient than Jia yu 93390 considering the caloric value increase.
