“…The significant effects of fertilization with castor cake as top-dressing only occurred at the highest irrigation depths because the moisture affects its mineralization, which results in the greater release of nutrients, particularly N (Lima et al, 2011). Boyhan et al (2007) report that N fertilization has a strong impact on onion production and is necessary to obtain higher bulb yields.…”

“…However, few studies have analyzed the effects that water availability and application have on the performance of organic fertilizers. The soil moisture affects the mineralization process of these materials, resulting in a greater release of nutrients, especially nitrogen (N) (Lima et al, 2011), which increases the productivity of onion bulbs (Boyhan, Torrance, & Hill, 2007;.…”

“…Castor cake is a byproduct of castor oil extraction (Magriotis et al, 2014); it contains 4.15, 0.61, and 0.96% of N, P, and K, respectively, and has a C/N ratio of approximately 11.6 (Zapata, Vargas, Reyes, & Belmar, 2012). Thus, it is considered a high-quality fertilizer (Lima et al, 2011). This material has been widely used in the production of vegetables in organic systems (Santos, Espíndola, Guerra, Leal, & Ribeiro, 2012).…”

“…The chemical composition of the pith is; cellulose (32.9 %), hemicellulose (9.61 %) and lignin (8.77). The composition not only varies at different positions on the stem, such as lower stem region, upper stem region or branch region but also with harvest seasons [18,47]. The composition reported by Li et al [18] was cellulose (33.19 %), hemicellulose (11.12 %) and lignin (15.48 %).…”

Lignocellulosic biomass is a rich source of cellulose and one of the most promising raw materials for the production of biofuels and other value added chemicals. However, its high lignin content and complex cellular structure represent a significant processing challenge. In this work, the effect of pretreatment using [EMIM][Ac] was studied at various process parameters in order to develop a cost-effective process. In order to minimize the loss of sugars in this process bulk of the solids, comprising both regenerated cellulose and undissolved particles were subjected to the enzymatic hydrolysis. Up to 96 % enzymatic digestibility was achieved, even with relatively coarse particle sizes (0.6-1.0 mm range), at 10 % biomass loading. The enhanced digestibility of CS is attributed to reduction in lignin content, crystallinity of the cellulose coupled with an increase in surface area.

“…biodiesel (Da Silva César and Batalha 2010). India is the world's largest producer of castor seed with an annual production of 590 × 10 6 kg and approximately 400 × 10 6 kg castor seed cake (RSC) remains after extraction of the oil (Lima et al 2011). The RSC is rich in N, so it could also easily be used as organic fertilizer (Ramachandran et al 2007), but might contain toxic compounds, e.g.…”

Extraction of oils from castor bean (Ricinus communis L.) and Jatropha curcas L. to produce biofuel is set to increase. The produced seed cake could be applied to soil as it is nutrient rich, but might affect soil functioning. Seven soils from Chiapas, México, were amended with seed cake of both plants while CO 2 , CH 4 and N 2 O emissions and mineral N concentrations were monitored in an aerobic incubation. The concentration of phorbol esters in the J. curcas seed cake (JSC) was 0.993 mg/g while no ricin was detected in the R. communis seed cake (RSC). Application of JSC increased CO 2 emission 2.5-times, N 2 O 12.6-times and CH 4 18.4-times compared to the unamended soil, while RSC CO 2 emission 2.1-times, N 2 O 21.3-times and CH 4 2.3-times. On average, 66% of the 88 mg organic N added with JSC was mineralized and 83% of the 101 mg organic N of the RSC within 56 days. It was found that J. curcas and castor bean seed cake increased CO 2 , CH 4 and N 2 O emission and mineral N in soil, without inhibiting soil microbial activity.
