Trash management after green cane harvesting and its effect on productivity and soil respiration † [Full subscriber]

A long-term trash management experiment is in progress at Cenicañas’ experiment station to evaluate the effect of continual retention of cane residues on the soil surface after green cane harvesting. The soil is a Mollisol with medium organic matter content (3.6%), high content of P (42 ppm) and K (0.46 cmol/kg) at the beginning of the study. Three trash loads of residues produced by the crop were evaluated: zero, single and double load of fresh residues were retained or removed from the soil surface of each treatment. To evaluate the nutrient supply from each load of residues, six fertiliser rates…
