“…Fertilization is an efficient way to increase rice yield and maintain food security (Lu et al., 2017; Wu et al., 2013). However, K fertilizer is often ignored by farmers compared with N and P fertilizer, which accelerates mining of soil K (Sui et al., 2015; Wang, Lu, Lu, Dai, & Li, 2012; Wu et al., 2014; Xu et al., 2014). With the use of high‐yielding varieties and the increase of multiple cropping indices, negative apparent K balances were widespread and K deficiency in soil has become a limitation for sustainable development of agriculture (Dobermann, Cassman, Mamaril, & Sheehy, 1998; Liu, Zhang, Zhang, Ficklin, & Wang, 2009; Wang & Wu, 2015).…”

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.

“…For example, Chowdhury et al (2000) observed that compared with rice husk and sawdust composts, a manure compost had high easily decomposable C, which was more effective to enhance soil microbial biomass C. Moreover, soil enzymes activities are closely associated with the rate of microbial mediated processes, and the diversity of enzyme is closely related to the complexity of soil organic matter (Paz-Ferreiro and Fu 2016). Thus, crop straw incorporated in soil can bring a large amount of organic matter and C, which will influence soil characteristics (Yadvinder-Singh et al 2004;Sui et al 2015).…”

“…Double cropping systems have been used in many countries (Heggenstaller et al 2008;Graß et al 2013;Sui et al 2015). For example, a wheat-cotton rotation system is widely used in the Yangtze River in China, and compared with a single system, two different kinds of straw are produced in double cropping systems (Sui et al 2015). In production, wheat straw and cotton residue are produced about 0.9 and 0.7 t•ha − 1 per year, respectively, in Yangtze River Valley.…”

Recently, Sui et al (2015) and Yu et al (2016) found that for the wheat-cotton rotation system, in the first and second year, 0.9 t•ha − 1 wheat straw or 0.7 t•ha − 1 cotton residue incorporation in soil before planting cotton could replace 150 kg•ha − 1 of inorganic K fertilizer for cotton growth. Then, they compared the influences of wheat straw, cotton straws and chemical K fertilizer on soil apparent K balance.…”

Background: Crop residue incorporation into the soil is an effective method to augment soil potassium (K) content, and effects of crop residue and K fertilizer on soil K balance have been compared. However, their influences on other soil characteristics such as carbon (C) and nitrogen (N) characteristics and microbial activities have not been quantified. To address this, field experiments were conducted in 2011 at Dafeng (sandy loam) and Nanjing (clay loam) in China with treatments including blank control without crop residue incorporation and K fertilizer application, 0.9 t•ha − 1 wheat straw incorporation (W1C0), 0.7 t•ha − 1 cotton residue incorporation (W0C1), 0.9 t•ha − 1 wheat straw + 0.7 t•ha − 1 cotton residue incorporation (W1C1) and two K fertilizer rates (150 and 300 kg•ha − 1 (K 2 O)) during the cotton season. Results: Compared with control, K fertilizer treatments did not alter soil water-soluble organic carbon/soil organic carbon (WSOC/SOC) ratio, microbial biomass carbon (MBC)/SOC ratio, MBC/microbial biomass nitrogen (MBN) ratio, water inorganic nitrogen/total nitrogen ratio (WIN/TN), the number of cellulose-decomposing bacteria, or related enzymes activities, however, W0C1, W1C0 and W1C1 treatments significantly increased WSOC/SOC ratio, MBC/SOC ratio and MBC/ MBN ratio, and decreased WIN/TN ratio at both sites. W0C1, W1C0 and W1C1 treatments also increased the number of soil cellulose-decomposing bacteria and activities of cellulase, β-glucosidase and arylamidase. Regarding different crop residue treatments, W1C0 and W1C1 treatments had more significant influences on above mentioned parameters than W0C1 treatment. Moreover, MBC/MBN ratio was the most important factor to result in the differences in the number of cellulose-decomposing bacteria and soil enzymes activities among different treatments. Conclusions: Short-term K fertilizer application doesn't affect soil C and N availability and microbial activities. However, crop residue incorporation alters soil C and N characteristics and microbial activities, and the influence of wheat straw is much stronger than that of cotton straw.
