The incorporation of previous crop residues in agricultural management benefits soil fertility, crop production, and environment. However, there is no enough information about maximum residue application level without negative effect over next crop yield. To evaluate maize (Zea mays L.) yield under short-time conservation management with incorporation and/or importation of different residue levels, a biannual rotation experiment was conducted in ash volcanic soil in south-central Chile. The experiment consisted of two previous crops, canola (Brassica napus L.) and bean (Phaseolus vulgaris L.), and four levels of residue incorporation (0%, 50%, 100%, and 200% of generated residue; from 0 to 21.4 Mg ha⁻¹ for canola and from 0 to 19.0 Mg ha⁻¹ for bean). Previous crop species and residue level affected some nutrients concentrations in grain and plant and some soil chemical properties, without effect in maize yield, which averaged 16.6 Mg ha⁻¹. Bean residue increased Ca and reduced S in maize plant, increasing soil P, Ca, Mg and K (P < 0.05). Maize grain Ca content was positively and proportionally affected by canola residue level and negatively and proportionally affected by bean residue level. All canola residue levels increased soil pH and Mg, but the highest level reduced soil S; soil P concentration increased proportionally with bean residue level. The highest bean residue level increased soil S. Different crop and levels of residue did not affect maize yield but did some plant nutrient concentration, and also affected some soil chemical properties.

将先前的农作物残留物纳入农业管理有利于土壤肥力，农作物生产和环境。但是，没有关于最大残留量施用水平的足够信息，而对下一季作物的产量没有负面影响。为了评估在短期保护管理下掺入和/或输入不同残留水平的玉米（Zea mays L.）的产量，在智利中南部的火山灰土壤中每两年进行一次轮作试验。该实验由以前的两种农作物油菜籽（芸苔）和菜豆（菜豆）和四种残渣掺入水平（0％，50％，100％和200％产生的残渣；从0到0）组成。 21.4 Mg公顷^-1双低油菜籽为0到19.0 Mg ha ^-1（豆为0 ）。先前的农作物种类和残留水平影响了谷物和植物中的某些养分浓度以及土壤的某些化学性质，而没有影响玉米产量，平均水平为16.6 Mg ha ^-1。豆渣会增加玉米植株中的Ca含量并减少S含量，从而增加土壤P，Ca，Mg和K（P <0.05）。玉米籽粒中钙含量受芥花籽油残留量的影响呈正比关系，受豆渣残留量的影响呈正比关系。所有低芥酸菜籽残留物水平均提高了土壤的pH和Mg，但最高水平则降低了土壤S。土壤磷含量与豆渣水平成正比。最高的豆渣水平增加了土壤S。不同作物和残渣水平​​不会影响玉米产量，但会影响植物的某些养分含量，还会影响土壤的某些化学性质。
