| No-tillage planting in mechanically-chopped secondary-forest seeks to replace slash-and-burning agriculture. We evaluated the effect of horizontal (HC) and vertical (VC) chopping-and-mulching mechanisms on vegetation fragmentation and decomposition rate and nutrient release from chopped residue, and on cassava production in eastern Amazon. Chopped-and-mulched residue was classified into four residue-size (Fs1 = 1?7, Fs2 = 7?25, Fs3 = 25?35, and Fs4 = >35 mm) and six residue-type (with husk/bark ? WB, partially chopped ? PC, compact ? C, partially shredded into fibers ? PS, completely shredded into fibers ? CS, and formless residue ? F) classes. In litter-bags, residual dry matter (DM) was determined at five different days after chopping-and-mulching and... |
