Sugarcane Straw Removal Enhances Short-Term N Source and N Source Efficiencies Under Sandy Soil Condition

The objectives of this study are to assess the effects of sugarcane straw removal with fertilizer application on (i) N source (soil mineral N, SOM lability (microbial biomass C and N)) and N source efficiency and (ii) the sugarcane straw decomposition. The field experiment used a randomized complete block design (RCBD) with three replications based on micro-plot size 1 m2 and litter bag study (32 weeks) at Khon Kaen University in a Yasothon sandy soil. A sugarcane straw dry weight (DW) of 6.25 tons ha−1 was used. There are eight treatments, i.e., burn (sugarcane straw burned after application), 50
