“…The high percentage of soil organic matter is influenced by the use of organic fertilizers (Mazur & Mazur, 2015), since the inclusion of techniques such as polyculture, favors the plant association, which benefits the soil stability and also can lead to a generation in average of 1.7 (Askari & Holden, 2015), which is coupled with the use of synthetic fertilizers, can lead to a reduction of soil organic carbon and Total N of 28 and 25%, respectively (Ponge et al, 2013).…”

Índice de calidad del suelo en fincas convencionales y semi-ecológicas productoras de plátano (Musa AAB simmonds cv. Dominic Harton) en Anolaima-Cundinamarca, Colombia AbstractThis research aimed to generate a soil quality index which have allowed to compare the effect of conventional and semi-ecological plantain farming systems. For its construction, we considered biometric data of near-to-harvest plants, physical, chemical and biological indicators which were evaluated using a principal components analysis; the weight of each indicator was calculated, and so were the response curves, establishing a minimum set of data which includes: sand percentage, sheet of water, pH, Nitrogen, organic carbon percentage, potassium, biodiversity conservation and microbial respiration, respectively. In fact, this index was validated in areas cultivated with plantain cv. Dominic Harton in farms located in the same taxonomic unit in Anolaima-Cundinamarca, Colombia. Results indicate that farms with semi-ecological practices had achieved a better soil quality than those with conventional practices.Key words: agriculture, alternative agriculture, indexes, agricultural practices, soil. ResumenEl objetivo de esta investigación es generar un índice de calidad del suelo que permita comparar el efecto de sistemas de producción de plátano convencionales y semi-ecológicos. Para su construcción se consideraron datos biométricos de plantas cercanas a la cosecha, indicadores físicos, químicos y biológicos que fueron evaluados a través de un análisis de componentes principales; se calculó el peso de cada indicador y además se establecieron las curvas de respuesta, estableciendo un Conjunto Mínimo de Datos, del cual hacen parte: porcentaje de arena, lámina de agua, pH, Nitrógeno, porcentaje de carbono orgánico, Potasio, conservación de la biodiversidad y la respiración microbiana. Este índice se validó en áreas cultivadas con plátano Dominico Hartón en fincas ubicadas en la misma unidad taxonómica en Anolaima, Colombia. Los resultados indican que las fincas que realizan prácticas semi-ecológicas presentan una mejor calidad de suelo que aquellas cuyo manejo es de tipo convencional.

“…Among the analyzed datasets, that of the scientific literature contains the smallest number of selected variables, and a smaller and less complex MD is desirable (Askari & Holden, 2015) for distributing and weighing soil quality indicators within the detailed functions in the model (Rousseau et al, 2012). …”

“…Proposed soil quality models are similar to SQI procedures as for the concepts and approachs, except that they include soil properties related to soil functions (regulation of hydrologic cycle, bioremediation of waste, carbon sequestration), in addition to the ones related to agricultural productivity. Karlen & Stott (1994) suggested a simple additive model that is widely used in the literature (Fernandes et al, 2011;Lima et al, 2013;Askari & Holden, 2015;Nakajima et al, 2015).…”

-The objective of this work was to assess soil quality indicators obtained with different datasets to compare soil management systems in the Brazilian Cerrado. Three criteria were used to select soil physical, chemical, and biological indicators: the full set of indicators obtained, with 36 parameters, for which all the physical, chemical, and biological soil properties were determined; a subset of indicators selected by principal component analysis (20 parameters); and a subset of indicators with some frequency of use in the literature (16 parameters). These indicators were obtained from the following management systems: no-tillage, conventional tillage, and native cerrado vegetation. Soil samples were collected at 0.0-0.1-m soil depth, and soil quality indicators were subjected to analysis of variance and their means were compared. The incorporation of soil native cerrado into agriculture decreased soil quality. The most commonly used indicators in the scientific literature are sensitive enough to detect differences in soil quality according to land use. Therefore, the selection of a minimum set of representative data can be more useful than a complex set of properties to compare management systems as to their soil quality.Index terms: no-tillage, principal component analysis, soil functioning, soil health, soil management, soil security. Seleção de indicadores da qualidade do solo para diferentes sistemas de manejo do solo no CerradoResumo -O objetivo deste trabalho foi avaliar indicadores da qualidade do solo, obtidos de diferentes bases de dados, para comparar sistemas de manejo do solo no Cerrado. Três critérios foram utilizados para a seleção de indicadores físicos, químicos e biológicos do solo: o conjunto completo de indicadores obtido, com 36 parâmetros, entre os quais todas as propriedades físicas, químicas e biológicas foram determinadas; um subconjunto de indicadores selecionados por análise de componentes principais (20 parâmetros); e um subconjunto de indicadores com alguma frequência de uso na literatura (16 parâmetros). Esses indicadores foram obtidos a partir dos seguintes sistemas de manejo: plantio direto, preparo convencional e cerrado nativo. As amostras de solo foram coletadas a 0,0-0,1 m de profundidade, e os indicadores de qualidade do solo foram submetidos à análise de variância e suas médias foram comparadas. A incorporação do solo de cerrado nativo à agricultura diminuiu a qualidade do solo. Os indicadores mais comumente utilizados na literatura científica são suficientemente sensíveis para detectar diferenças de qualidade do solo de acordo com o uso da terra. Portanto, a seleção de um conjunto mínimo de dados representativos pode ser mais útil do que um conjunto complexo de atributos, para comparar sistemas de manejo quanto à qualidade do solo.Termos para indexação: plantio direto, análise de componentes principais, funcionamento do solo, saúde do solo, manejo do solo, segurança do solo.

“…Crop rotation is paramount for achieving the largest production and best quality of the potato (Campiglia, Paolini, Colla, & Mancinelli, 2009), mainly for interrupting life cycles of pests and diseases (Keiser Häberli & Stamp, 2012) and improving soil quality (Askari & Holden, 2015). However, the herbicides used in rotation crops such as corn and wheat can persist in the soil and impair growth and development of the potato plant.…”

ABSTRACT. Crop rotation improves potato (Solanum tuberosum L.) crops; however, in some cases, it can have some negative effects due to the herbicides previously used in crops under rotation. These effects are the decline in the yield and the appearance of physiological disorders, including cracked tubers, which impair the quality and economic value of the potato. Two field experiments were performed with applications of tembotrione and atrazine, alone or in combination. In the Rio Paranaiba (Minas Gerais State) area, in clay soil, the herbicides were applied at post-emergence in corn (Zea mays L.). After corn harvest and soil preparation, the potatoes were planted. In the Serra do Salitre (Minas Gerais State) area, in the medium texture soil, the herbicides were applied and incorporated into the soil, and the potatoes were planted the day after. No injuries were found in the shoots. Decline in the potato yield was found only in the medium texture soil (Serra do Salitre). Atrazine did not affect the quality of potato tubers. In the two areas, tembotrione promoted cracks in "Atlantic" potato tubers.Keywords: Atlantic; herbicide; physiological disorder; Solanum tuberosum.Carryover de tembotrione e atrazine afeta a produtividade e a qualidade de tubérculos de batata RESUMO. A cultura da batata (Solanum tuberosum L.) é favorecida pela rotação de culturas e, em alguns casos, desfavorecida pelos efeitos adversos dos herbicidas utilizados anteriormente nas culturas em rotação. Esses efeitos são redução de produtividade e desordens fisiológicas como, por exemplo, rachaduras de tubérculos, que reduzem a qualidade e valor comercial da batata para consumo in natura ou processamento industrial. Em dois experimentos de campo foram realizadas aplicações de tembotrione e atrazine, isolados ou em mistura. Na área de Rio Paranaíba (Estado de Minas Gerais) em solo de textura argilosa, os herbicidas foram aplicados na cultura do milho (Zea mays L.) em pós-emergência e na área de Serra do Salitre (Estado de Minas Gerais) em solo de textura média, foram aplicados e incorporados um dia antes do plantio da batata. Não foram observadas injúrias na parte aérea das plantas. A produtividade de batata foi reduzida somente no solo de textura média (Serra do Salitre). O atrazine não influenciou a qualidade dos tubérculos de batata. Nas duas áreas o tembotrione causou rachaduras em tubérculos de batata "Atlantic".
