“…Potassium is an essential macronutrient for rice growth. The amount of K required by rice is relatively high, which normally exceeds P but is close to N (Che et al., 2016; Xu et al., 2015). Potassium is not involved in the structure of plant tissues, it mainly acts as a regulator or cofactor of many enzymes involved in osmoregulation, carbohydrate and protein metabolism (Britto & Kronzucker, 2008; Nieves–Cordones at al., 2019).…”

“…(2017), only 144 kg K 2 O ha −1 for wheat ( Triticum aestivum L.) and 192 kg K 2 O ha −1 for rice achieved a positive K balance for the cropping system. In general, rice crop utilized about 162 kg K for a yield of 7.8 t ha −1 , while only 15% of the K was transported to the grain (Che et al., 2016). These high levels of K in straw mean that retaining straw in fields will return a considerable amount of plant K to the soil, thus alleviating the apparent negative K balance in the soil (Buresh et al., 2010; Zhang et al., 2010; Zhang et al., 2017; Zhao et al., 2014).…”

Yield and potassium uptake of rice as affected by potassium rate in the middle reaches of the Yangtze River, China Abstract Potassium is an essential macroelement for rice (Oryza sativa L.), but K deficiency in paddy ecosystems has increased widely and limited sustainable rice production in China. Two-year field trials were conducted with five K levels (0, 60, 120, 180, and 240 kg K 2 O ha -1 , designated as K0, K60, K120, K180, and K240) in Qichun county, Hubei Province, to investigate grain yield, K uptake characteristics, and K use efficiencies of rice. The results showed that application of K increased rice yield by 9.8-29.3%, compared to K0. No significant differences were observed in rice yield among the K120, K180, and K240 treatments. The K uptake in aboveground biomass increased linearly with the K rate, while K harvest index decreased. As K uptake increased, rice yield increased linearly at first and then stabilized, showing the phenomenon of luxury consumption of K. The growth period for fast K uptake in different rice varieties and K levels was 29-67 d after transplanting, and sufficient nutrient supply is needed to ensure the increase of rice yield and growth during this period. Internal use efficiency (IUE), agronomic efficiency (AE), and physiological efficiency (PE) declined as the application rate of K increased. These results indicated that absorption and utilization of K in rice were affected by the K supply rates, and that luxury consumption occurred when K application was excessive. The luxury consumption of K by rice was mainly stored in straw.Abbreviations: AE, agronomic efficiency; F1, Fengliangyouxiang no. 1; H3, Hua'an no. 3; IUE, internal use efficiency; KHI, K harvest index; L6326, Liangyou 6326; PE, physiological efficiency; RIE, reciprocal internal efficiency; t 1 , the beginning peak period; t 2 , peak period; t 3 , the end peak period; v m , the maximum uptake rate of potassium; Y6, Yangliangyou no. 6; Δt, the time of potassium rapid accumulation lasted.

“…Wheat ( Triticum aestivum L.), rice ( Oryza sativa L.) and corn ( Zea mays L.) are three major crops worldwide and are also the main crops in China, making up 67.5% of the total crop yield (Wang et al, 2012). Table 6 lists the average crop residue yield (Che et al, 2016; Meng et al, 2016; Zhao et al, 2013), grain yield (Che et al, 2016; Chuan et al, 2013; Meng et al, 2016), K, Ca and Mg contents of crop residue and grain (Huang et al, 2016; Niu et al, 2016; Tang et al, 2014; Xu, He, et al, 2013; Xue et al, 2017; Zhao et al, 2013) and required amounts of nutrients for wheat, rice and corn. The table also lists the calculated biochar needed annually in the acidic soil region of China considering the corresponding total leaching percentages of K, Ca and Mg (Figure 4b).…”

Biochar affects base cation retention and leaching when it is used to enhance the base cation status of acidic soil. However, the details of its contribution are not yet clear. In this study, six loadings of corn straw biochar (0%, 2%, 4%, 6%, 8% and 10%, w/w) were applied to an acidic Ferralsol and incubated for 1 year. The results showed that the content of water‐soluble and exchangeable base cations of K, Na, Ca and Mg increased with increasing levels of biochar in amended soil. The percentage of water‐soluble Na, Ca and Mg of amended soil significantly decreased, while the percentage of exchangeable K, Ca and Mg increased significantly after the addition of biochar. For K and Na, biochar affected their leaching concentrations both as a source and by increasing the pH. For Ca, biochar reduced Ca leaching when the biochar loading was ≥4%, and the contribution increased from 30.8% to 100% at 4%–10% loading. For Mg, biochar reduced Mg leaching at biochar loadings 2%–10%, the reduction increasing from 22.0% to 70.5%. The results show that corn straw biochar can increase the content of the soil nutrient base cations K, Ca and Mg by increasing their exchangeable forms and enhance soil retention by decreasing their leaching. Thus, corn straw biochar can be used to effectively improve acidic soil base cation fertility.

“…Brazil, as one of the main producers of cattle beef in the world, presents a great potential for the use of slaughterhouse waste as organic fertilizer. An adequate management of fertilization is essential to increase rice productivity (Che et al, 2016). However, research shows that an efficient use of nutrients by rice is influenced by the type of cultivar (Crusciol et al, 2016).…”

Due to the expansion of the slaughterhouses sector, there is huge availability of waste from agricultural products. These waste products may be used as alternative for the production of organic fertilizers. Fertilizer efficiency depends on the type of rice cultivar. Thus, traditional, intermediate and modern plant types may respond differently to the combined use of mineral and organic fertilizers. The objective of this study is to evaluate the effects of different combinations of mineral and organic fertilizers based on slaughterhouse waste on the development, productivity and industrial quality of upland rice cultivars. The soil of the the experimental area was a typical clayey dystroferric Red Latosol and the climate of the region is Aw: humid tropical, rainy in the summer and dry in the winter according to the Koppen classification. The experimental design was randomized blocks arranged in a 3 x 6 factorial design. We evaluated three different types of rice cultivars (Caiapó, traditional type; BRS Primavera, intermediate type; and IAC 202, modern type) and levels of combinations of mineral and organic fertilizers (100% mineral, 80% mineral + 20% organic, 60% mineral + 40% organic, 40% mineral + 60% organic, 20% mineral + 80% organic, 100% organic). The cultivar IAC 202 presented a productive potential higher than the cultivars Caiapó and BRS Primavera. The 60% mineral + 40% organic and 40% mineral + 60% organic fertilizer combinations produced more yield in comparison with the 100% organic fertilizer. The cultivar Caiapó showed the highest grain quality. Organic fertilizer based on slaughterhouse waste can be used for upland rice farming.
